Single Click has always been “To control fixtures with Wyze Bulbs only”.
You have to use the “Additional Controls” area. There you can set Double-Click, Triple, and long-press.
Here’s a nice long thread from 3 years ago that I started where I was fighting with the Additional Controls. Wyze Switch - Dbl-Triple Tap functions work ... and then they don't?
This bug is still present in the switches. It doesn’t always happen but mess with those settings too much and they will stop working. If you get hung up just blank out all the settings in Additional Controls to make them empty. Back out of the switch, refresh your app, then go back in and set everything up the way you want. Editing what you’ve setup is where the bug comes in. If you change them too much (edit, go out, come back, edit, etc), then the Double-Click/Triple/Long action stops working. So you have to go through the blanking procedure I mentioned.
Not great. But, they work when left alone. We click the **** out of mine in my house.
