From the case description I could understand that issue is related to switch not powering on
1. Is this a new installation ? Was the setup working fine before ?
2. Was there any power outage that occurred ?
3. On your switch while it's plugged into the outlet, do you see any lights on? (Amber or green) Please let us know which lights are on. (Please refer to the below picture and share a picture of the same)
Please let us know if you have any queries in this regard.
