2nd (child) device handler for ST

I see now that you need 2 device handlers for smartthings. What is the second devise handler for?

I might have answered my own question, looks like its for the LED Notifications?

Yeah, the child switch driver lets you configure the “notification LED” settings on the device and create child devices that are switches you can use to activate the notification LED with your selected configuration. If you don’t use that feature (or have the Black series), you don’t really need it, but in the provided ST DTH it’s really the only way to get notifications set up.

Good news is now (almost 1.5yrs later), the second (child) handler is no longer needed :slight_smile:
