Can I Toggle More Than One Light From A Scene Controller Button?

Scene Controller buttons can be configured for ON / OFF toggle control of an individual Decora Smart Wi-Fi device.  On/Off toggle control using one button for a group of lights is not supported.

Scene controller button can be configured to run an Activity or a Scene.

The best solution for multiple light control is to use a Scene, Activities, or the Control Multiple Devices group option.

Locate the card for the D2SCS or DW4BC and then tap the three dots in the upper right corner.  Tap the button you would like to program and tap Yes to confirm that this is the button you would like to program.    

Select Group Control 

Select the devices that you want to program to this button and then tap Next

Now set the state of the devices, ON / OFF / Dim Level, etc. and then tap Next

Enter a name for the button and then tap Save.
