Merge pull request 'v0.18.0: channel-2 auto-responder with extensible #command boilerplate' (#38 ) from feat/channel2-autoresponder into main

Add channel-2 #command auto-responder (v0.18.0)
Event-driven CommandService dispatches exact case-sensitive #command matches on COMMAND_CHANNEL (default 2) through a single-registration-point registry; first command #ping -> #pong!. Replies ride COMMAND_CHANNEL: directed DM back to the sender when present, else broadcast. Failing handler/send only logs a warn. DI: CommandModule's factory injects MeshService and attaches itself via MeshService.attachCommands() — a constructor-level cycle leaves one side null in NestJS 12's injector (verified), so no forwardRef is used. Tests 106 -> 121; docs synced (AGENTS.md, MESHTASTIC.md, README).

 # Changelog
 ## v0.18.0 — 2026-09-25 17:08
 - New channel-index-2 auto-responder (`src/commands`): an event-driven `CommandService` reacts to decoded rx text on `COMMAND_CHANNEL` (env, default `2`) and dispatches exact `#command` matches (case-sensitive, surrounding whitespace trimmed) through a single-registration-point registry — handlers registered in the constructor via `register(name, fn)` receive `{ text, from?, id? }` and return a reply string or void (= no reply). First command: `#ping` → replies `#pong!`.
 - Reply routing v1: directed DM back to the sender when present, else broadcast — always on `COMMAND_CHANNEL`, via the existing `MeshService.sendText(to, text, undefined, channel)` path. No threading/`replyId` in v1. A failing handler or send only logs a warn; it never crashes the app.
 - Wiring: `MeshService` gains an optional third constructor param (`commands?`) plus a public `attachCommands()` — the rx handler calls `this.commands?.onRx(channel, text, from, id)` right after `notifyRx()`, fire-and-forget like the notifier. DI note: a constructor-level MeshService ↔ CommandService cycle leaves one side null in NestJS 12's injector (verified empirically), so `CommandModule` provides `CommandService` via a factory that injects `MeshService` and attaches itself as a side effect — no `forwardRef`, no module cycle.
 - Tests: 106 → 121 specs — directed/broadcast replies on ch2, non-command-channel and non-command text ignored, case-sensitive exact match, whitespace trimming, `COMMAND_CHANNEL` override, void handler = no reply, extensibility (second registered command), failing handler/send swallowed; end-to-end over the fake bridge (`#ping` on ch2 answered with a directed `#pong!` tx record, ch3 not answered); DI spec asserts both sides of the wiring resolve to real instances.
 - Docs: AGENTS.md "Other" bullet + MESHTASTIC.md "Channels & sending" describe the auto-responder; README env list gains `COMMAND_CHANNEL`.
 ## v0.17.0 — 2026-09-25 16:18
 - The mesh→agent notify gate is now a comma-separated multi-channel list: `MESH_NOTIFY_CHANNEL` (default `3`) parses to channel indices, each entry trimmed, empty/invalid entries ignored (`"3,0"` → `[3, 0]`).
 - ch0 DM-only filtering: ch0 is the shared default channel where other users talk — only directed messages (both sender and recipient present) notify there; ch0 broadcasts and undirected traffic are ignored. Synthetic injections (`POST /api/messages`, `injectMessage`) ride ch0 by design and stay exempt from the rule, so they still notify when 0 is in the list.
 - `notifyRx()` gains optional params: `to?` (the packet's destination, now passed through from the rx handler) and an `injected` flag; the field is renamed `notifyChannel` → `notifyChannels`. Self-echo filter unchanged.
 - Tests: 102 → 106 specs — multi-list match/non-match, ch0 broadcast ignored even with 0 in the list, ch0 directed DM notified, ch0 injection notified via a multi-list, invalid env entries ignored.
 - Docs: AGENTS.md + MESHTASTIC.md "Notifications" describe the list semantics and the ch0 DM-only rule; README env bullet/forwarded/notifier lines and the controller's `GET /api/forwarded` description kept in sync. Local `.env` (gitignored) now `MESH_NOTIFY_CHANNEL=3,0`.
 ## v0.16.0 — 2026-09-25 15:49
 - New `GET /api/forwarded`: the last 100 rx texts that passed the notify gate and were forwarded to opencode, newest first as `{ id, from?, text, channel, at }[]` — the id is the packet id (real rx) or generated record id (injected), `from` omitted when there is no sender. Backed by an in-memory ring buffer in `MeshService`, recorded in `notifyRx()` at hand-off: after the channel gate (`MESH_NOTIFY_CHANNEL`) and self-echo filter pass, right before the `OpencodeService.notify()` call; an unwired notifier records nothing (a notifier disabled internally still counts — MeshService cannot see its enabled flag). In-memory only, reset on restart. Purpose: a replying agent gets exactly the notified subset with packet ids instead of scanning all of `/api/messages`.
 - Tests: 96 → 102 specs — ring records on a gated forward (shape + newest-first via `forwarded()`), no record on channel mismatch / self-echo / unwired notifier, injected messages count when they pass the gate (`from` omitted when absent), cap at 100 with oldest evicted.
 - Docs: README endpoint bullet + curl example; AGENTS.md endpoints list kept in sync with the controller.
 ## v0.15.0 — 2026-09-25 15:40
 - New `POST /api/respond` endpoint and MCP `respond(messageId, content)` tool: reply to an earlier message by packet id with automatic routing — the caller never thinks about where it goes. rx records are answered as a DM back to the original sender unless the original was a broadcast (then the reply is a broadcast), tx records go to their own destination, injected messages without a sender get a broadcast. The reply always rides the record's channel and carries `replyId = messageId`, so the recipient app renders it as a threaded quote of that packet. Returns `{ id }`; 400 on invalid messageId/content, 404 when no message has the given id (in memory or in SQLite), 503 when the bridge is down; MCP tool errors carry the same messages.
 - Captured rx history records now persist their destination (`to: pkt.to`) — no schema change needed: the `to_node` column already existed for tx rows and flush/seed already round-tripped it, so captured packets simply fill it in too. This is what lets a reply tell a DM from a broadcast original.
 - The opencode notifier wrapper now includes the packet id: msg = `New mesh message (id <packetId>)[ from node <n>]: "<text>" — please react to it.` — the id is the rx packet's id, or the generated record id for injected messages; the `from node` part is still omitted when absent.
 - Tests: 88 → 96 specs. New: captured-rx row persists `to_node`; six `respond` service specs (rx DM → directed send back to sender on the original channel with wire-level replyId, broadcast original → broadcast reply, tx record → its destination/channel, SQLite fallback when the record is outside the in-memory buffer, 404 memory+DB miss, 400 validation matrix); MCP `respond` wiring spec (routing + unknown-id/out-of-range/empty-content tool errors) and the tool list grows to ten.
 - Docs: README gains the endpoint bullet, a curl example, the MCP tool entry and the updated notifier wrapper format; AGENTS.md endpoints/MCP/notifier lines kept in sync with the controller.
 ## v0.14.0 — 2026-09-25 14:11
 - The standalone Python notify forwarder (`ops/forwarder`, compose service `forwarder`) is gone: its logic now lives in-process as a new `src/opencode` module — an `@Injectable()` `OpencodeService` registered in `MeshModule` and injected into `MeshService`. When an RX text lands on channel `MESH_NOTIFY_CHANNEL` (default 3), `MeshService.notifyRx()` calls `void this.opencode.notify(text, from)` instead of the old webhook POST; the channel gate and self-echo filter stay in `MeshService`, everything else (workspace/session resolution, message POST, retries) moved into the service.
 - Ported forwarder behavior 1:1 with new env names: `OPENCODE_API` (default `http://172.24.0.1:9898` — opencode binds 0.0.0.0 on the host and is reachable from the bot container over dev_net; the old forwarder used 127.0.0.1 only because it ran with `network_mode: host`), `OPENCODE_WORKSPACE_PATH` (default `/home/krzyw/projects/sandbox/mesh-bot`), `OPENCODE_SESSION` (empty = discover the most recently updated session per request; non-empty = pin that session and skip discovery), `OPENCODE_USER` / `OPENCODE_PASS` (HTTP Basic auth on every call). Missing/empty credentials disable the notifier instead of failing: one warn at construction, `notify()` is a no-op — the app keeps running.
 - Workspace/session resolution per request (no caching — messages are rare): `GET {api}/api/workspaces` → match by `path == OPENCODE_WORKSPACE_PATH`, fallback name `mesh-bot`, status `ready` preferred when several match; then, unless pinned, `GET {proxyPath}/session` → most recently updated session (`time.updated`; first entry when none carry it). The message POST body is exactly `{"parts":[{"type":"text","text":msg}]}` with msg = `New mesh message[ from node <n>]: "<text>" — please react to it.` (em-dash, not a hyphen; the `from node` part omitted when there is no sender).
 - Timeout semantics preserved: every call has a 15 s timeout (`AbortSignal.timeout(15000)`); a read timeout on the final message POST means DELIVERED — opencode accepts immediately but holds the response until the agent turn finishes — so it is treated as success and never retried. Workspace/session GET failures are ordinary retryable failures: backoff [2 s, 10 s, 30 s] (the constant moved here from `mesh.service.ts`), up to 4 attempts total, final failure logs `opencode notify dropped after N attempts`.
 - `MeshService` loses `notifyUrl`, `postNotify()` and `NOTIFY_RETRY_DELAYS_MS`; the constructor gains an optional second parameter (`db?, opencode?`) so all existing direct constructions in specs keep working — without a notifier wired, `notifyRx()` is a no-op.
 - `docker-compose.yml`: forwarder service block deleted; bot environment drops `MESH_NOTIFY_URL`, keeps `MESH_NOTIFY_CHANNEL`, and passes the five `OPENCODE_*` vars via `${VAR:-default}` interpolation from `.env`. Local `.env` (gitignored) renamed `FORWARDER_USER/PASS/SESSION` → `OPENCODE_USER/PASS/SESSION` (values unchanged, session pin kept), added `OPENCODE_API=http://172.24.0.1:9898`, dropped the `MESH_NOTIFY_URL=` line.
 - Tests: new `src/opencode/opencode.service.spec.ts` (12 specs — exact wrapper text with/without `from` incl. em-dash and Basic auth header, workspace path match / name fallback / ready preference, session pin vs discovery-by-max-time.updated vs first-entry fallback, POST timeout = delivered success with no retry, GET failure retried then succeeds, give up after 4 attempts with the dropped log, disabled-when-no-creds no-op + construction warn). `mesh.service.spec.ts` notify block rewritten around a mocked `OpencodeService`: channel gate (default 3), off-channel skip, injected channel-0 case incl. `from` passthrough as undefined, self-echo skip for rx and injected; the ten webhook-specific tests (URL/body/retry/HTTP-error/give-up) are gone — retry semantics now live in the opencode spec.
 - Docs: README "Notify forwarder" section replaced by "Opencode notifier", env-var list updated (`MESH_NOTIFY_URL` bullet removed, `OPENCODE_*` documented); AGENTS.md webhook paragraph rewritten for the built-in notifier; MESHTASTIC.md notification rule updated. All FORWARDER_* mentions removed from tracked files (CHANGELOG history keeps them as-is).
 ## v0.13.1 — 2026-09-25 13:02
 - Battery-low alerts now ride channel "testowy" (index 2) instead of the pinned send channel ("test", index 3): `BatteryAlertService` reads new env `BATTERY_ALERT_CHANNEL` at construction (default `2`, same pattern as its other env config) and passes it through the existing `MeshService.sendText(to, text, replyId?, channel?)` path — which gained an optional trailing `channel` argument defaulting to the pinned `MESH_SEND_CHANNEL`, so every other sender (API, MCP, weather) is untouched. Threshold, cooldown, merged one-message-per-cycle format and @mentions are unchanged.
 - Tests: battery specs now assert the send carries channel index 2 by default plus a `BATTERY_ALERT_CHANNEL` override case; the end-to-end case asserts the alert frame rides channel 2 while the pinned send channel stays at its default 3. All pre-existing specs stay green.
 ## v0.13.0 — 2026-09-25 12:34
 - New non-AI `src/battery` module: `BatteryAlertModule` + `BatteryAlertService`, wired into `app.module.ts` exactly like the weather module (ScheduleModule.forRoot() + MeshModule). Every `BATTERY_CHECK_INTERVAL_MS` ms (default 60000, read at construction) it scans the same node state that backs `GET /api/nodes` and collects every node whose reported battery is at or below `BATTERY_ALERT_THRESHOLD` percent (default 20); when any qualify it sends AT MOST ONE broadcast per cycle containing all of them — never one message per node, and nothing at all when none qualify. The comparison is `<=` on purpose — a node sitting exactly at the threshold counts as low; tests pin this choice.
 - Alert format: `⚠️ battery low: @!<8-hex-lowercase-node-num> (<longName or shortName>) <X>%` with additional nodes appended as `, @!<hex> (<name>) <Y>%` (the single-node case is the same template with one entry) — Meshtastic mention syntax (`@!` + zero-padded 8-char lowercase hex, e.g. `@!09a2b3c4`), entries kept tight so common cases stay near the ~190-char single-packet limit; the name part falls back longName → shortName and is omitted entirely when a node reported no name. Broadcasts ride the pinned send channel via the existing `MeshService.sendText(BROADCAST_ADDR, text)` path (MESH_SEND_CHANNEL, default index 3) — no new transport.
 - Anti-spam: per-node cooldown of `BATTERY_ALERT_COOLDOWN_MS` ms (default 21600000 = 6 h) in an in-memory `Map<nodeNum, lastAlertEpochMs>` — only nodes outside their window are included in a batch and the alert timestamp is recorded for every node in it after sending, so a node is alerted at most once per window; the map resets on process restart by design (a node may get one duplicate alert after a deploy).
 - Live battery updates: `batteryLevel` was previously only populated from NodeInfo frames during the initial sync. Live NODEINFO_APP packets (port 4, serialized meshtastic.NodeInfo in Data.payload) now update `deviceMetrics` in the node database too — new `decodeNodeInfo()` + `PORT_NODEINFO_APP` in codec.ts, one branch in the existing packet-handling path — so alerts and `/api/nodes` reflect current values between syncs. Unknown nodes get a stub entry when they report metrics live; malformed payloads are skipped like every other port.
 - Tests: new `src/battery/battery.service.spec.ts` (mention hex padding/lowercase, batched message construction incl. multi-node append, name fallbacks and the 190-char ceiling, threshold boundary with default + custom env, no-battery skip, all qualifying nodes merged into exactly one broadcast, send-failure never throws, cooldown suppression within window + re-alert after expiry via fake timers, in-cooldown node excluded from a batch while an out-of-window node still triggers the single message) plus a DI spec mirroring weather's; an end-to-end case drives a real MeshService over the fake bridge and asserts the alert frame rides channel index 3 with the exact text. `mesh.service.spec.ts` gains a NODEINFO_APP live-update case (stale sync battery refreshed, other fields preserved, unknown-node stub). All pre-existing specs stay green.
 ## v0.12.8 — 2026-09-25 12:04
 - Docs (MESHTASTIC.md response protocol): new standing rule per owner request ("remember to always replay on reply on channel when question is send here") — questions received via mesh are **answered on the channel**: every question sent via mesh gets its actual answer broadcast back on the same channel when work completes; an acknowledgement alone is not sufficient, and the answer must not stay only in the private agent session. All existing bullets (always-respond-first, channel-only/no DMs, owner authority 2594370888, language, NO_RESPONSE quirk, self-echo note) unchanged. No code changes — all 64 tests untouched and green.
 ## v0.12.7 — 2026-09-25 11:40
 - `POST /api/send` and the MCP `send_message` tool now accept an optional `replyId` (integer in 1..0xffffffff) referencing an earlier message's packet id from `GET /api/messages` / `get_messages`. When set, the recipient app renders the sent text as a threaded reply/quote of that packet. The value rides Meshtastic's protocol-level reply mechanism: `Data.reply_id` (field 7) on the TEXT_MESSAGE_APP payload.
 - `buildTextToRadio(to, text, channelIndex, replyId?)` in `src/mesh/codec.ts` gained the optional param and sets **camelCase** `replyId` on the Data value (`replyId ?? 0`). The JS protobufs package silently drops snake_case `reply_id`, so camelCase is mandatory; a byte-level spec asserts wire tag `0x3d` (field 7, fixed32) appears iff `replyId` was given.
 - `MeshService.sendText(to, text, replyId?)` passes the value through to the codec. REST validation rejects non-integers and out-of-range values with a 400; MCP validates via zod (`z.number().int().min(1).max(0xffffffff)`). Omitting it leaves the field unset (proto3 default 0, not serialized) — existing callers are unaffected.
 - New specs: codec byte-level `0x3d` presence/absence check and a service outbound-capture case asserting `Data.replyId === <id>` when given and `0` when omitted. All 62 pre-existing tests stay green (64 total).
 - Docs: README endpoint + MCP tool lines, AGENTS.md API section, and the controller's `@ApiOperation` description now document the optional `replyId`.
 ## v0.12.6 — 2026-09-25 10:55
 - Docs (MESHTASTIC.md response protocol): reverted the v0.12.5 reply rule per owner preference ("we will talk on that channel") — replies to messages from a specific node now go back **on the same channel as a broadcast** (no `to`), no direct messages; broadcasts are used for both replies and general announcements such as the hourly weather report. The always-respond-first bullet (**ALWAYS respond ... BEFORE starting any work it triggers**) and every other rule are unchanged. No code changes — `POST /api/send` and the MCP send tool already accept an omitted `to` (broadcast).
 ## v0.12.5 — 2026-09-25 10:45
 - Docs (MESHTASTIC.md response protocol): replies to messages from a specific node now go back **as a direct message to that sender's node number** (`to` = the sender's node num), so they surface in the direct conversation thread ("flagged as reply") instead of as new channel posts.

No code changes — `POST /api/send` and the MCP send tool already accept a `to` target; all other rules (owner authority 2594370888, language, confirm-first-then-work, channel pinning, self-echo note, NO_RESPONSE quirk) unchanged.

 ## Response protocol
 - **ALWAYS respond to a received mesh message on the Meshtastic BEFORE starting any work it triggers** — acknowledge first, then work. This is mandatory for every action triggered by a chat message; the confirmation goes out before you start (so the user gets the fastest possible response).
- Replies to messages from a specific node go back **as a direct message to that sender's node number** (`to` = the sender's node num), so they surface in the direct conversation thread ("flagged as reply") instead of as new channel posts. Broadcasts (no `to`) are reserved for general announcements such as the hourly weather report.
+- Replies to messages from a specific node go back **on the same channel as a broadcast** (no `to`) — do not send direct messages; per owner preference, all conversation happens on the channel. Broadcasts are used for both replies and general announcements such as the hourly weather report.
 - **Questions are answered on the channel** — every question sent via mesh gets its actual answer broadcast back on the same channel when work completes; an acknowledgement alone is not sufficient, and the answer must not stay only in the private agent session.
 ## Channels & sending
 - All bot sends ride channel index 3 ("test") by design (`MESH_SEND_CHANNEL`, default "3") — never the primary channel.
 - Broadcasts show up in `/api/messages` as `failed` / `NO_RESPONSE` on this firmware — known quirk, not a real failure; the message was transmitted.
 - Channel index 2 carries the bot's auto-responder (`COMMAND_CHANNEL`, default 2): exact `#command` texts (case-sensitive) get an automatic reply on that channel — directed back to the sender when present, else broadcast. Currently only `#ping` → `#pong!`. This is a mechanical echo for testing the mesh path; it is not the agent and does not mean the owner has seen anything.
 ## Notifications (mesh → agent)
- RX text on the notify channel (`MESH_NOTIFY_CHANNEL`, default 3) triggers an outbound webhook POST `{text, from}` to `MESH_NOTIFY_URL` (host forwarder :4097 → opencode session). Messages from our own node are never notified (self-echo filter, v0.11.2).
+- RX text on a channel in the notify list (`MESH_NOTIFY_CHANNEL`, comma-separated indices, default 3) is pushed in-process to the live opencode session by `OpencodeService` (workspace/session resolved per request from the opencode API; disabled without `OPENCODE_USER`/`OPENCODE_PASS`). Messages from our own node are never notified (self-echo filter, v0.11.2).
 - Channel 0 is the shared default channel where other users talk: it carries real DMs when both sender and recipient are present, and the bot listens there too — but only directed messages trigger notifications; ch0 broadcasts are ignored. Synthetic injected messages (channel 0) are exempt from this rule.

-## Notify forwarder
+## Opencode notifier
-Second compose service (`ops/forwarder`, `python:3.12-slim`, stdlib only): receives the bot's outbound notify webhook POSTs (`{text, from?}` on `MESH_NOTIFY_URL`) and forwards each one as a message to the mesh-bot folder's live opencode session (Basic auth). The opencode workspace UUID is regenerated on host restarts, so the forwarder resolves it dynamically per request via the opencode API: `GET /api/workspaces` → match by `path == FORWARDER_WORKSPACE_PATH` (fallback name `mesh-bot`, status `ready` preferred when several match) → `GET {proxyPath}/session` → most recently updated session (`time.updated`; first entry if absent). No caching — messages are rare. Runs with `network_mode: host` — it listens on the host's `0.0.0.0:4097`, which is why `MESH_NOTIFY_URL=http://172.24.0.1:4097/notify` works from the bot container, and reaches opencode at `127.0.0.1:9898`. `restart: unless-stopped`; no Traefik labels (host networking).
+In-process service (`src/opencode`, no separate compose service): when an rx text message arrives on a channel in the `MESH_NOTIFY_CHANNEL` comma-separated list, it pushes it to the mesh-bot folder's live opencode session (Basic auth). On ch0 only directed DMs are pushed — broadcasts there are ignored. The opencode workspace UUID is regenerated on host restarts, so the notifier resolves it dynamically per request via the opencode API: `GET {OPENCODE_API}/api/workspaces` → match by `path == OPENCODE_WORKSPACE_PATH` (fallback name `mesh-bot`, status `ready` preferred when several match) → `GET {proxyPath}/session` → most recently updated session (`time.updated`; first entry if absent). No caching — messages are rare. The message POST body is exactly `{"parts":[{"type":"text","text":msg}]}` with msg = `New mesh message (id <packetId>)[ from node <n>]: "<text>" — please react to it.` (the `from node` part omitted when there is no sender; the packet id is the rx packet's id, or the generated record id for injected messages). opencode accepts the message immediately but holds the HTTP response until the agent turn finishes, so a 15 s read timeout on that POST means **delivered** — treated as success, never retried; workspace/session GET failures are retried up to 3 times with backoff (2 s / 10 s / 30 s) before being dropped.
 Config lives in `.env` (gitignored) and is passed via compose environment — credentials are never committed to the repo:

+- `OPENCODE_API` (default `http://172.24.0.1:9898`) — opencode API base URL as seen from the bot container (dev_net bridge → host; opencode binds 0.0.0.0 on the host)

+- `OPENCODE_USER` / `OPENCODE_PASS` — Basic auth credentials; missing/empty **disables** the notifier (one startup log line, no-op) instead of failing

kamilkrzywda	931b42bb1e	Add channel-2 #command auto-responder (v0.18.0) CI / build + unit (pull_request) Successful in 41s Details Event-driven CommandService dispatches exact case-sensitive #command matches on COMMAND_CHANNEL (default 2) through a single-registration-point registry; first command #ping -> #pong!. Replies ride COMMAND_CHANNEL: directed DM back to the sender when present, else broadcast. Failing handler/send only logs a warn. DI: CommandModule's factory injects MeshService and attaches itself via MeshService.attachCommands() — a constructor-level cycle leaves one side null in NestJS 12's injector (verified), so no forwardRef is used. Tests 106 -> 121; docs synced (AGENTS.md, MESHTASTIC.md, README).	2026-09-25 17:11:52 +00:00

kamilkrzywda	1b712f7eee	battery: send alerts on channel "testowy" (index 2), not the pinned send channel CI / build + unit (pull_request) Successful in 1m0s Details Owner request. BatteryAlertService reads new env BATTERY_ALERT_CHANNEL (default 2) at construction and passes it through MeshService.sendText, which gains an optional trailing channel argument defaulting to the pinned MESH_SEND_CHANNEL — every other sender is untouched.

kamilkrzywda	fe8d2dbe0b	battery: merge multiple low-battery nodes into one broadcast per cycle CI / build + unit (pull_request) Successful in 1m0s Details Owner follow-up: 'if multiple ppl shows at once — merge messages to one'. check() now collects every qualifying node (at/below threshold and not within its per-node cooldown) and sends AT MOST ONE broadcast per cycle containing all of them, recording the alert timestamp for each after sending; nothing is sent when none qualify. Format: '⚠️ battery low: @!<hex> (<name>) <X>%[, @!<hex> (<name>) <Y>%]' — single-node case uses the same one-entry template. Cooldown semantics unchanged.	2026-09-25 12:51:25 +00:00
kamilkrzywda	d0b71e6e91	battery: low-battery alert module (v0.13.0) BatteryAlertModule + BatteryAlertService wired into app.module like the weather module. Every BATTERY_CHECK_INTERVAL_MS (default 60 s) the service scans the node state backing GET /api/nodes and broadcasts a single-packet '⚠️ @!<8-hex> battery low: <X>% (<name>)' alert for every node at or below BATTERY_ALERT_THRESHOLD percent (default 20, <= on purpose) not alerted within BATTERY_ALERT_COOLDOWN_MS (default 6 h, in-memory map — resets on restart). Sends ride the pinned send channel via MeshService.sendText like every other bot send.	2026-09-25 12:39:45 +00:00
kamilkrzywda	8ddd91d4b5	mesh: update node batteryLevel from live NODEINFO_APP packets battery_level was only populated during the initial sync; NodeInfo frames streamed as NODEINFO_APP (port 4) now refresh deviceMetrics in the node database so /api/nodes and downstream consumers see current values between syncs. decodeNodeInfo + PORT_NODEINFO_APP added to the codec, one branch in the existing packet-handling path.	2026-09-25 12:39:45 +00:00
