Tapo L900 light strip power meters became unavailable

hmm, this change has side effects for Powercalc :-(
Also see #2142, where other integration / light causes similar problems now.

Fact is previously Tapo L900 only reported hs as possible color_mode of the light. That is the color mode for color control.
However now the entity suddenly also reports color_temp. This breaks powercalc as there are no measurements made for this color mode.
The check No lookup file found for mode is raised upfront during powercalc sensor setup to report issues in early stage, but this error causes the powercalc sensor to not be setup at all.

Not sure how to resolve yet. I'm tempted to just remove the validation on startup all toghether. But than problems will arise whenever a user puts this light on color_temp.

Could you try if color_temp mode is working at all for this lightstrip? Might be that it is falsly reported as a supported_color mode.

It's even worse than that, because TapoLight reports following color_modes:

{<ColorMode.COLOR_TEMP: 'color_temp'>, <ColorMode.BRIGHTNESS: 'brightness'>, <ColorMode.HS: 'hs'>, <ColorMode.ONOFF: 'onoff'>}

That combination should never be possible at all.
brightness and onoff should be only supported color mode of it's own and never be mixed. According to HA specifications: https://developers.home-assistant.io/docs/core/entity/light/#color-modes

So the main issue is in TapoLight integration which is reporting wrong color modes for the light.
I would suggest you to raise an issue in TapoLight repository as this error with the color modes should be fixed in that integration. https://github.com/petretiandrea/home-assistant-tapo-p100/issues
