Home Assistant

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"}.

## 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.

## 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.
