Wyze Switch is not a dimmer switch.
However, with Smart Control enabled, you may be able to configure your controls to lower the brightness setting on your smart bulbs.
In the Wyze app, tap on your Wyze Switch, then the Settings gear. If you have Smart Control enabled (tap Single Press to check) then you add an Action under Additional Controls for Double Press, Triple Press, or Press and Hold to set the brightness of your bulbs.
