Feedback

Running Home assistant 2021.11.5 with native tuya integration
DS03 fan/light combo switch which used to work using localtuya but now does not have full functionality.

It currently only allows on or off.

There is no light control nor fan speed control available in home assistant

Hey there @tuya, @zlinoliver, @METISU, @frenck, mind taking a look at this feedback as it has been labeled with an integration (tuya) you are listed as a code owner for? Thanks!
