Question about light temperature

[pszafer]

Hi,

I have Xiaomi Bedside lamp and your library after set colour is always returning "temperature 0".
If I set temp by app it returns proper light temp, at least looks like K.
Is it some different unit or why is it 0?

First or second gen lamp? It could be a bug, but IIRC it also reports the kelvin values properly when the lamp itself is in the temperature mode, and otherwise simply 0.

Bluetooth only, so first generation I think.
I'm asking because for some reason google_assistant component in HA is trying to get light temperature, and if it is then I've got division by 0 error.

I've changed it to somethink like this for now in _status_cb:

        else:
            if self._dev.temperature > 0:
                self._ct = int(kelvin_to_mired(self._dev.temperature))
            else:
                self._ct = int(kelvin_to_mired(2400))

but for me it somehow no logical that I got temperature 0, it should always return some K temp in any light mode.

Please feel to submit a PR to change the behavior, if you wish to do so. But returning "some K temp" in any mode would cause inconsistent behavior when changing between modes / depending on what commands are being executed, so I don't think that's the correct approach.
