(R5093 Smart Light Strip) TypeError: unsupported operand type(s) for *: 'int' and 'NoneType'

[MartinCarbol]

Hi,

I'm using R5093 Smart Light Strip (7raeccy3ar12nn9x) with Tuya-local integration.

The service light/turn_on returns an error when I'm trying to switch the LED strip on. Sometimes it works well but then many times in a row not.

Please see the log.

Thanks for your time.

[make-all]

Release 0..19.3 contains a fix for the issue indicated in the logs. My guess is that on lights that only return color_temp when in the rgb color mode, this may occur due to lack of data in the info from the light.
