I recently had Caseta devices professionally installed in my home; however, I am having issues with two of the dimmers. With one dimmer, when I use Alexa to turn on the lights, the lights start flashing. In another case I cannot add the dimmer to the Lutron app on my phone. I have tried doing the factory reset on the device and it won't work. The rest of the devices are all working fine. Can someone please help? Thanks!
