docs(home-assistant): add HA reference for the lodge
Covers access (WS/REST API, no SSH, no backups), the dual Nest integration (cloud Google Nest + local Matter), the 2026-06-15 Matter fabric loss and on-site recommission steps, the temp scripts (label-driven, serialized to dodge the Nest SDM 429), and the Lovelace dashboard layout. Registered in SKILL.md references. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# Home Assistant
|
||||
|
||||
<overview>
|
||||
HA OS at `home.thelonglakelodge.com`, proxied via fritzlab sjc001 remote-proxy
|
||||
to `172.24.24.50:8123` (also directly reachable on the lab network). Supervisor
|
||||
Observer on `:4357` (read-only health, no auth). API token in `~/.env` as
|
||||
`HA_TOKEN` (long-lived user token — has core API + service calls, but NOT the
|
||||
`/api/hassio/*` Supervisor proxy → 401). No SSH (`:22` closed, no terminal addon).
|
||||
No automatic backups configured (`backup/info` → 0 backups).
|
||||
|
||||
Local control via WebSocket: `wss://home.thelonglakelodge.com/api/websocket`,
|
||||
auth with `{"type":"auth","access_token":HA_TOKEN}`. Useful WS cmds:
|
||||
`config_entries/get`, `config/device_registry/list`, `config/entity_registry/list`,
|
||||
`matter/node_diagnostics{device_id}`, `lovelace/config{url_path:null}` /
|
||||
`lovelace/config/save`. Addon control via REST service:
|
||||
`POST /api/services/hassio/addon_restart {"addon":"core_matter_server"}`.
|
||||
</overview>
|
||||
|
||||
<thermostats>
|
||||
## Nest thermostats are integrated TWICE
|
||||
|
||||
The 8 Nest thermostats appear via two independent paths:
|
||||
- **Cloud (Google Nest)** — `nest` integration, entities `climate.*_google_nest`
|
||||
(+ `climate.lodge_basement` = Basement Living Room) and per-zone
|
||||
`sensor.*_temperature` / `sensor.*_humidity`. Reliable; cloud-dependent.
|
||||
- **Matter (local)** — `matter` integration via the `core_matter_server` addon,
|
||||
entities `climate.*_nest`. Local control, but see incident below.
|
||||
|
||||
8 zones: Office, Kitchen, Bunkhouse Kitchen (forced-air "HVAC"); Eat-in Kitchen,
|
||||
Primary Bathroom, Basement Living Room, Basement Bedroom, Tub Room (in-floor heat).
|
||||
Matter fabric id `1E5211CA4C7B5275`, node ids 1–5,7,8,9 (temp sensors are bridged
|
||||
endpoint-101 sub-devices of their thermostat node).
|
||||
|
||||
`script.set_away_temperatures` (HVAC 55–78 / in-floor 55) and
|
||||
`script.set_occupied_temperatures` (HVAC 68–76 / in-floor 67) set all zones,
|
||||
targeting by **label**: `hvac` (3 forced-air) and `in_floor_heat` (5 in-floor),
|
||||
both applied to the cloud `*_google_nest` devices (resolved in-script via
|
||||
`label_devices(..) | map('device_entities') | ... | select('match','climate')`
|
||||
since the labels are on devices, not entities). Commands are **serialized one
|
||||
zone at a time with an 8 s delay** — firing all 8 at once trips the Google Nest
|
||||
SDM per-user `ExecuteDeviceCommand` rate limit (429 RESOURCE_EXHAUSTED). (Matter copies carry parallel
|
||||
`matter_hvac` / `matter_in_floor_heat` labels — used by the scripts before the
|
||||
2026-06-15 repoint to cloud.) `google_nest` labels all 8 cloud devices.
|
||||
</thermostats>
|
||||
|
||||
<matter-outage>
|
||||
## Matter fabric loss (2026-06-15)
|
||||
|
||||
At 2026-06-15 13:53 UTC an HA Core/Supervisor restart (Supervisor → 2026.06.1)
|
||||
left the `core_matter_server` addon (v8.5.0) with an **empty fabric** — all 11
|
||||
Matter devices report `node_not_found`, all 59 `climate.*_nest` etc. entities
|
||||
`unavailable`. Integration reconnects fine (config entry `loaded`); the server
|
||||
simply has zero nodes. Addon restart + config-entry reload do NOT restore them
|
||||
(storage lost, not transient), and there is no backup to restore from.
|
||||
|
||||
Cloud Nest is unaffected → thermostat control intact via `*_google_nest`.
|
||||
|
||||
Recovery = re-commission each thermostat on-site (non-destructive, no factory
|
||||
reset needed — Nest supports Matter multi-admin):
|
||||
1. On lodge WiFi, Google Home app (lodge account) → tap thermostat → Settings →
|
||||
"Linked Matter apps & services" → "Link apps & services" → generate a Matter
|
||||
setup code (11-digit / QR). Code is single-use, ~5 min TTL.
|
||||
2. HA → Settings → Devices & Services → Matter → Add device → enter the code.
|
||||
Wait ~1–2 min; node appears (bridged temp sensor comes with it).
|
||||
3. Repeat per thermostat (one code at a time). Rename to match.
|
||||
4. Delete the stale unavailable Matter devices afterward.
|
||||
Then re-point dashboard climate tiles back to `climate.*_nest` if local control
|
||||
is wanted (see dashboard note).

||||

|
||||
## Main Lovelace (`lovelace` / "Overview", storage mode)
|
||||
|
||||
Views: `main` (single grid card, columns:1, headed sections: locks/lights,
|
||||
Helpful Scripts, Water Sensors, then climate as three 2-col thermostat-card
|
||||
grids — **Lodge HVAC** (office, kitchen), **In-Floor Heat** (5 in-floor zones),
|
||||
**Bunkhouse** (bunkhouse kitchen)),
|
||||
`Environmentals` (history page), and `Lock Management`. Edit via
|
||||
`lovelace/config` / `lovelace/config/save` (WS).
|
||||
|
||||
HVAC climate tiles point at the **cloud** `*_google_nest` entities (repointed
|
||||
off the dead Matter `*_nest` during the 2026-06-15 outage). The `Environmentals`
|
||||
page is three per-category vertical-stacks (Lodge HVAC / In-Floor Heat /
|
||||
Bunkhouse), each with Temperature, Humidity, and Heating/Cooling history-graphs
|
||||
(72h) scoped to that category's entities.
|
||||
If Matter is re-commissioned and local control is preferred, repoint these back.
