Thank you for posting this information. I’m sure it took you a lot of time and effort to do that.
Just got my Wyze thermometer working after paying OnTech $99 to install it. Their installer did a great job even though he had only installed Google Nest thermometers.
My forced air furnace thermometer only had two wires so it would not work with the included Wyze C wire adapter. It was mounted upstairs and the furnace is downstairs which made running a C wire unrealistic. He recommended installing the Wyze thermometer downstairs closer to the furnace and was easily able to run a new cable and connect everything.
No problem controlling it from the Wyze app but I couldn’t get it working with Alexa. Called tech support and Stephanie walk me through that and I was able to use Alexa Through My Echo Dots to control it. I went out shopping and when I came home the thermostat was not working and not connected to anything. I deleted it from the Wyze and re-installed it and now it’s working again. Not sure why equipment but at least I know what to do to fix it.
Also, apparently there is a significant temperature differential between downstairs and upstairs that affects the thermostat so I have to set the temperature higher to warm up the living area. It’s always a learning curve with new gadgets.
Kudos to Wyze tech support (aside from a long wait on the phone) and OnTech for working the problem. The installer said OnTech is owned by Dish Network.
