Wyze Thermostat // Issues With Dual Band Networks

Hey everyone,

I’m having trouble with my Wyze Thermostat. I’m in contact with Support, but I wanted to discuss it here in case others are experiencing similar issues.

Lately, my thermostat struggles to maintain target temperatures. It seems like the problem arises when the thermostat attempts to switch between wifi bands. Whenever the temperature reaches around 19/20 degrees Celsius, the thermostat shows an ‘offline’ status. This leads to the heating turning off, and the thermostat won’t start heating again until I manually restart it in the advanced settings.

I’ve noticed that the thermostat only supports 2.4GHz signals, so I separated the bands on my router. Despite re-adding the thermostat to my account using the 2.4GHz network, the advanced settings still indicate it’s connected to the old dual-band network.

My internet setup is with T-Mobile, using their “Home Internet” Package with a modem/router combo running both bands. I currently have the device connected to a personal router.

Has anyone else experienced similar issues on an aggregated network?

I have not experienced anything like what you are. I would be surprised if Wyze T-stat does not perform default heating and cooling operations when not connected to Wi-Fi. Can anyone confirm what T-stat does when offline?

I am having the same issue I was able to connect all my other devices no problem but when it came time to reconnect the thermostat it will not even give me the option so I put in a 2.4 I set it up and I still can’t get the thermostat to work I cannot get it to connect and this is a brand spanking new thermostat cuz my other one stopped working but I did not know that you could set up that with a router also that’s interesting

Sadly but thankfully, I have resolved other Wyze WiFi connection problems with restarting my router. Maybe it will work for you.

That is an odd problem. Why is it switching over from your preferred router? Both are stationary objects, one might assume.
