Recently added the Xiaomi Gateway and I see that all lumen values wrong:
What can it be?
I’m having this issue as well… Not related to HA I don’t think, just an issue with the gateway itself. Every time I toggle the lights in my room where my gateway is, the value changes to a random lumens value. Sometimes it will go up in value if I turn the lights off, and sometimes it will drop in value when I turn the lights on. Not sure what’s wrong, maybe a gateway firmware issue. Hopefully they will fix that in the future.
I don’t think it not related to HA, when I use mijia app to set “when the illumination low, turn on the light” and it can manage it, but when I connected with the HA, the values of the sensor are incorrect as your sensor…
