Home Assistant

HA OS at `home.thelonglakelodge.com`, proxied via fritzlab sjc001 remote-proxy to the lodge LAN. Use the public HTTPS/WSS path; direct `172.24.24.50:8123` is unapproved IPv4 inventory, not an operational path. API token in `~/.env` as `HA_TOKEN` (long-lived admin token — core API + service calls + Supervisor: WS `{"type":"supervisor/api","endpoint":...}` for JSON endpoints, REST `/api/hassio/addons//logs` for text logs; `/api/error_log` is 404 — use WS `system_log/list`). No SSH (`:22` closed, no terminal addon). No automatic Supervisor full-backup schedule. Local recovery backups include `pre-matter-recommission 2026-07-05` and `post-matter-recommission-2026-07-15`.

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. Retained as fallback.
• Matter (local) — matter integration via the core_matter_server addon, entities climate.*_nest. Primary control path.

8 zones: Office, Kitchen, Bunkhouse Kitchen (forced-air "HVAC"); Eat-in Kitchen, Primary Bathroom, Basement Living Room, Basement Bedroom, Tub Room (in-floor heat).

script.set_away_temperatures (HVAC heat_cool low/high 55–78 / in-floor 55) and script.set_occupied_temperatures (HVAC heat_cool low/high 68–76 / in-floor 67) set all zones, targeting Matter device labels matter_hvac (3 forced-air) and matter_in_floor_heat (5 in-floor). Both run with no delays and resolve device labels to climate entities via label_devices(..) | map('device_entities') | ... | select('match','climate') because labels are on devices. Verified 8/8 for both profiles on 2026-07-15. Cloud devices retain google_nest plus hvac / in_floor_heat labels; any cloud fallback script must serialize commands with an 8 s delay to avoid the Google SDM ExecuteDeviceCommand 429 limit.

## 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.

The 9.0.0 Python→matter.js migration created fabric 2; the old compressed fabric 1E5211CA4C7B5275 is gone. Recovery completed 2026-07-15 by recommissioning all 8 thermostats through Nest multi-admin. Cloud Nest remained available throughout.

## Matter fabric 2 (complete)

core_matter_server 9.1.0 runs matter.js. All nodes are available:

Node	Device	Climate entity	Category	Child sensor
16	Lodge Kitchen Nest	climate.lodge_kitchen_nest	matter_hvac	Lodge Kitchen Sensor Nest
17	Lodge Office Nest	climate.lodge_office_nest	matter_hvac	Lodge Office Sensor Nest
18	Bunkhouse Kitchen Nest	climate.bunkhouse_kitchen_nest	matter_hvac	Bunkhouse Kitchen Sensor Nest
19	Lodge Primary Bathroom Nest	climate.lodge_primary_bathroom_nest	matter_in_floor_heat	—
20	Lodge Eat-in Kitchen Nest	climate.lodge_eat_in_kitchen_nest	matter_in_floor_heat	—
21	Lodge Basement Bedroom Nest	climate.lodge_basement_bedroom_nest	matter_in_floor_heat	—
22	Lodge Tub Room Nest	climate.lodge_tub_room_nest	matter_in_floor_heat	—
23	Lodge Basement Living Room Nest	climate.lodge_basement_living_room_nest	matter_in_floor_heat	—

Every thermostat also has matter_nest. Eight thermostat nodes plus the three bridged sensors equal 11 HA Matter devices. All stale fabric-1 registry devices are deleted.

Recommissioning requires a phone on lodge WiFi; Google Home refuses to generate a Matter code off-network:

1. Google Home app (lodge account) → thermostat → Settings → Linked Matter apps & services → Link apps & services → 11-digit code (single-use, ~5 min).
2. WS {"type":"matter/commission","code":"<code>","network_only":true} (or HA UI Add device).
3. Rename device to " Nest", label matter_nest + matter_hvac (Office, Kitchen, Bunkhouse Kitchen) or matter_in_floor_heat (the 5 in-floor zones), rename climate entity to climate.<zone>_nest.

GOTCHA — Address unreachable / commission timeout after host boot can be a wedged matter.js socket (1 of 1 attempt(s) failed, 1 discovered). Restart core_matter_server, then retry. Do not treat add-on restart as lost-fabric recovery.

post-matter-recommission-2026-07-15 (backup id 2e0efde0) includes HA, database, and core_matter_server data on hassio.local. The nightly Git export does NOT contain Matter fabric storage. Automatic Supervisor backups remain off.

## 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).

Overview thermostat cards point at all 8 local Matter climate.*_nest entities. The Environmentals page remains cloud-backed: three per-category vertical-stacks (Lodge HVAC / In-Floor Heat / Bunkhouse), each with Temperature, Humidity, and Heating/Cooling history graphs (72h). Five in-floor thermostats have no Matter humidity entity, so cloud humidity remains required there.
