Xiaomi gateway light unavailable after exactly 2,5 hours (Solved)

Hardware
20

So, I think this quick and dirty fix will help. I’ve checked it on 1.4.1_164.0158 firmware and HA 0.87.0

Don’t forget to backup files!
Right now I have no other xiaomi sensors, so can’t check. But I hope they should work as usual.

  1. Enable polling.

Find this code in the xiaomi_aquara component (xiaomi_aquara.py)
In my venv it’s located here at /opt/homeassistant/lib/python3.6/site-packages/homeassistant/components/

    @property
    def should_poll(self):
        """Return the polling state. No polling needed."""
        return False

And change False to True

    @property
    def should_poll(self):
        """Return the polling state. No polling needed."""
        return True
  1. Illumination sensor still does not change the value, no matter we turn light or not.
    Let’s add update def for sensor.
    File is nearby: ./sensor/xiaomi_aquara.py
    def update(self):
        """Get data from hub."""
        _LOGGER.debug("Update data from hub: %s", self._name)
        self._get_from_hub(self._sid)
  1. Next code is for light ./light/xiaomi_aquara.py

This might not needed, but it’s quick and dirty :slight_smile:

Add this to turn_on and turn_off defs:

self.schedule_update_ha_state()

Result should be like this:

    def turn_on(self, **kwargs):
        """Turn the light on."""
        if ATTR_HS_COLOR in kwargs:
            self._hs = kwargs[ATTR_HS_COLOR]

        if ATTR_BRIGHTNESS in kwargs:
            self._brightness = int(100 * kwargs[ATTR_BRIGHTNESS] / 255)

        rgb = color_util.color_hs_to_RGB(*self._hs)
        rgba = (self._brightness,) + rgb
        rgbhex = binascii.hexlify(struct.pack('BBBB', *rgba)).decode("ASCII")
        rgbhex = int(rgbhex, 16)

        if self._write_to_hub(self._sid, **{self._data_key: rgbhex}):
            self._state = True
            self.schedule_update_ha_state()

    def turn_off(self, **kwargs):
        """Turn the light off."""
        if self._write_to_hub(self._sid, **{self._data_key: 0}):
            self._state = False
            self.schedule_update_ha_state()
  1. Restart HA and wait 2.5 hours :slight_smile:
  2. Check traffic by ngrep. You should see read and read_ack every 30 sec.
