Ever since 2021.11.1 my Tuya dimmers act like regular switches. They show as dimmers but the slider does not adjust brightness. Not sure what model the dimmers are but they are from Costco about a year ago - the google home app and the Tuya app control the brightness just fine but home assistant does not. Correct brightness is displayed, ie it changes if I adjust on another app or with the switch.
Running home assistant on a dedicated raspberry pi 4 with most recent updates on everything.
