Well folks, I was able to get wireshark on the thermostat. I found that it is trying to contact these addresses: 54.209.187.172 107.21.255.187 3.214.34.120 Right now none are reachable. I am trying to figure out why this thermostat is trying to reach those addresses. When I do a whois, they come up as being hosted on Amazon... I wonder if one of them comes awake every so often and the thermostat gets the connection and receives a TZ change... So far I have not been able to catch it doing so. When I bought the unit I intentionally did NOT try to use the cloud service, I have tried to get proper communications with Radio Thermostat but so far only idiots... And they do not have a published telephone number.
