Hello! Ordered and installed 2 Wyze thermostats December 2020. My house has separate units for upstairs and downstairs and neither have C wires so I used the included C wire adapter.
A few weeks ago I came home to both thermostats dead. Then, the one on my downstairs unit appears to have overloaded and shorted itself out, as you can see in the above pic.
I was out of town so perhaps there was an electrical surge or something while I was away. The transformer for the downstairs unit was also blown.
After tearing the things down, it looks like the blown component was a fuse on the back side. The upstairs unit looks unharmed, but still does not work.
Did I wire these things up wrong or something? I followed the step by step directions in the app closely and as far as I know I did everything correctly. Both thermostats were installed identically.
Any help or information is appreciated. Thank you!
