Adds Home Assistant as a service provider with two coordinated surfaces:
Notifications (subscription):
- Long-lived WebSocket client (aiohttp ws_connect) with auth handshake,
exponential-backoff reconnect, bounded event queue, and area-registry
enrichment cached per (re)connect
- ServiceProvider ABC gains an optional `subscribe()` method for push-style
providers; HomeAssistantServiceProvider uses it via a per-provider
supervisor task started in the FastAPI lifespan
- 4 event types (state_changed, automation_triggered, call_service,
event_fired), 4 default Jinja templates (en + ru), HA-specific
tracker filters (entity_glob, domain_allowlist, exact entity ids)
- Extracted shared dispatch pipeline (api/webhooks.py → services/
event_dispatch.py) so subscription and webhook ingest share the same
event_log + deferred-dispatch + quiet-hours code path
Bot commands:
- /status, /entities [glob], /state <entity_id>, /areas
- Multi-command WS session so /status and /areas cost one handshake
- Sensitive-attribute blocklist (camera access_token, entity_picture, etc.)
and 30-attribute cap to keep /state output safe and within Telegram's
message size
- Error-message redaction strips URL userinfo before surfacing to chat
Frontend:
- HA descriptor with toggle ConfigField type (new) and tag-input filter
mode for free-text glob/domain lists (new TagInput component)
- 15 command slots + 4 notification slots wired into the existing
template-config UI
