Never got it to work, could they be bad switches?

Can an HS220 go bad? Lights just stopped working one day. I had one left from the 3 pack I bought and replaced it and the light started working again. All the lights on the switch worked and showed...

Before and after pictures, main just blinks amber/orange and manual switch doesn't work.

Installed per instructions but main switch just blinks amber, which according to directions means it's resetting to factory defaults. What now?

One on Amazon, but it's no longer available.
