This blocks ALL other integrations from completing setup.\n\n**Log:**\n2026-04-06 18:50:39.442 WARNING (MainThread) [homeassistant.bootstrap] Setup timed out for\nbootstrap waiting on {\u003cTask pending name='Task-604'\ncoro=\u003cHisenseWebSocket._connect_ws() running at\n/config/custom_components/hisense_ac_plugin/websocket.py:119\u003e\nwait_for=\u003cFuture pending cb=[Task.task_wakeup()]\u003e cb=[set.remove()]\u003e} - moving forward\n\n**Expected behavior:** The websocket connection should either complete quickly or fail gracefully \nwithout blocking HA startup. Consider using `hass.async_create_background_task()` instead of \nblocking the setup phase.\n\n### Bug 2: TypeError in switch.py line 474 (15 occurrences per boot)\n\nAfter startup, multiple `TypeError: 'NoneType' object can't be awaited` errors are logged \nfrom `switch.py:474`. With 5 AC units × 3 switches each, this generates 15 errors per boot.\n\n**Log:**\n2026-04-06 18:45:21.509 ERROR (SyncWorker_5) [homeassistant] Error doing job:\nTask exception was never retrieved (task: None)\nTraceback (most recent call last):\nFile \"/config/custom_components/hisense_ac_plugin/switch.py\", line 474, in _async_schedule_update\nawait self.async_schedule_update_ha_state(True)\nTypeError: 'NoneType' object can't be awaited\n\n**Expected behavior:** `_async_schedule_update` should check if `async_schedule_update_ha_state` \nreturns a valid awaitable before awaiting it, or handle the None case gracefully.\n\n### Additional warnings (non-blocking)\n\nThe integration also logs these warnings for each device, which is expected behavior \nbut worth noting:\nWARNING [custom_components.hisense_ac_plugin.number] No supported numbers found\nWARNING [custom_components.hisense_ac_plugin.water_heater] Skipping unsupported device: 009-199 (...)\nWARNING [custom_components.hisense_ac_plugin.humidifier] Skipping unsupported device: 009-199 (...)\n\nThese are just informational (009-199 are AC units, not water heaters/humidifiers), but could \nbe silenced to keep logs clean.","author":{"url":"https://github.com/pifma","@type":"Person","name":"pifma"},"datePublished":"2026-04-06T17:35:18.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":5},"url":"https://github.com/28/HomeAssistantPlugin/issues/28"}
