Salut tout le monde !

Ce sujet est désormais en cours de développement.

Une PR a été ouverte pour permettre à l’assistant IA de répondre sur l’état des piles :

Implements feature request: https://community.gladysassistant.com/t/concernant-l…ia-etat-des-piles/10354 This PR was opened by an automated Claude Code run and needs human review before merging. ### Description The forum request asks the AI to answer questions such as « donne moi l'état en % de toutes les piles » and « quel est l'état de la pile du capteur température salon ». **What was missing:** battery levels are ordinary device features (`DEVICE_FEATURE_CATEGORIES.BATTERY`, type `integer`, unit percent), but the `battery` category is **not** part of `sensorFeatures` in `server/services/mcp/lib/selectFeature.js`. As a consequence the AI could not read them at all today: battery features never appear in the `schema://home` resource, they are absent from the `device_type` enum of `device.get-state`, and a `device.get-state` call filtered on them returns nothing. So neither of the two questions above could be answered — this is not a duplicate of an existing tool. **What this PR adds:** - `isBatteryFeature` in `selectFeature.js` (alongside the other feature predicates) and wired on the `MCPHandler` prototype. - A new `device.get-battery-levels` MCP tool in `buildSchemas.js`, registered only when at least one device of the home reports a battery level, like `device.set-shutter`, `device.set-light`, `sensor.set-state` and `device.get-energy-consumption` are. Categories: `device_query` and `other`. - Optional `device` and `room` parameters (both zod enums built from the home), so the same tool serves the "all batteries" question (no parameter) and the "this one sensor" question. - Each entry carries the room, the device name, the feature name, the category, the value, the unit and the `age` of the value, through the shared `formatValue` helper — same shape as `device.get-state`, so the existing prompt rules about `age` apply unchanged. - Fresh values are read with `device.getBySelector` at call time, like `device.get-state`, instead of the cached list built when the tools are registered. - Error branches modelled on the neighbouring tools, all returning an explicit sentence instead of an empty list (an empty result is the case where a model invents a plausible value): unknown room (with the list of the real rooms, "No room" excluded), unknown device name (with the list of the devices that do report a level), and a scope with no battery powered device. - A prompt rule in `server/config/prompts/aiChat.prompt.txt` pointing the model at `device_get_battery_levels` for every battery question, telling it that devices absent from the result do not report a level, and what to say when the tool is not available. **Sorting choice:** results are sorted by level ascending, lowest battery first, because what a user asking for the state of all their batteries actually wants is the ones to replace — and a model summarizing a long list answers from its head. Devices that have never reported a level (`last_value` null) are kept at the end rather than sorted as if they were 0. **Deliberately not done:** the `battery` category was *not* added to `isSensorFeature`. That would have been the smaller diff, but every battery feature would then be added to the home schema and to every `device.get-state` answer, where it is noise for questions about temperature, lights or shutters, and it would also have made battery features writable through `sensor.set-state` for MQTT devices. Only `battery` (percentage) is covered; `battery-low` (binary) is left out of scope. ## Forum Forum: https://community.gladysassistant.com/t/concernant-lia-etat-des-piles/10354 ### Checklist - [x] Tests pass: `cd server && npm run coverage` (Codecov requires 100% coverage on changed lines) and Cypress (`npm run cypress:run`) if the UI changed - [x] Linter and prettier pass on both front and server (`npm run eslint`, `npm run prettier`) - [x] No undocumented breaking change Details on what was actually run: - `npm_config_service=mcp npm run test-service` → 144 passing, including 4 new tests: the sorted whole-home listing (with a device without a room and two devices that never reported a level), filtering by device and by room, the three error branches, and the tool not being registered when no device has a battery. Every existing `mcpHandler` mock in `buildSchemas.test.js` got `isBatteryFeature` added, since `getAllTools` now calls it. - `c8` over the MCP suite: no uncovered line and no uncovered branch in the new code (`selectFeature.js` at 100%). The only lines `c8` reports as uncovered in `buildSchemas.js` (798-801, a `device.turn-on-off` branch) are pre-existing and untouched. - `npm run eslint` in `server/`: 0 errors (only pre-existing warnings elsewhere in the repo, none in the touched files). `npm run prettier-check`: clean. - `test/lib/gateway/gateway.forwardMessageToAiChat.test.js`: 43 passing. Not run: the full server suite. `test/lib/gateway/gateway.restoreBackupEvent.test.js` has 2 failures, verified identical on an untouched checkout of `master` — unrelated to this change. - No front-end change, so Cypress was not run. --- _Generated by [Claude Code](https://claude.ai/code/session_013yxguVaLdJ8ZKmw5x3HePT)_ ## Summary by CodeRabbit - **New Features** - Added battery-level information for supported devices. - Battery readings can be filtered by device, room, or home. - Results are sorted from lowest to highest charge level. - Low-battery indicators reflect configured warning thresholds. - Unavailable or missing readings are clearly handled. - Electric vehicle and home storage batteries are excluded from results. - Battery tools are available only when supported by the connected devices. - **Bug Fixes** - Improved validation for unknown device and location filters. - Added more reliable handling of sensor state and persisted settings.
