NV Enegybprovides customers with a wifi thermostat. When I switched to T Mobile home internet I lost connectivity.
NV Energy believes it is because T Mobile is a hot spot and not hardvwired internet.
In the reset instructions the thermostat does show up in my list of wifi options and does connect, but never prompts me for wifi password.
Note:. I have wifi lights that also uses 2.4, and was promoted to enter a password, and they work.
