I’ve been using Wyze thermostats for the past few months, and while they’ve been mostly reliable, I’ve encountered some puzzling behavior that I’d like to share and hopefully get some advice on.
The Setup: I have two heat pumps installed over 11 years ago, both maintained regularly. Recently, one thermostat started acting up, prompting me to replace both with Wyze thermostats. The installation was straightforward, and both units worked perfectly for about two days.
The Problem: Both thermostats have started behaving unpredictably. They randomly change the differential temperature from 1 degree to 2 or 3 degrees, leading to rooms getting too warm until I manually restart the thermostat via the app. This issue occurs sporadically—about 50% of the time—and seems to persist even after multiple reboots and software updates.
What I’ve Tried: I’ve reinstalled the thermostats three times, ensured the latest updates are installed, and checked all wiring connections. The Wi-Fi connection is stable, and I can access the thermostats remotely. Interestingly, my Wyze cameras on the same network haven’t shown any interference.
Theories: I’m considering whether this could be a manufacturing issue since both thermostats were purchased at the same time. It’s also possible that there’s a software bug or a compatibility issue with my heat pumps.
Next Steps: I plan to continue monitoring the thermostats for a few more weeks. If the issue persists, I’ll likely switch to a different brand. In the meantime, I’d love to hear if anyone else has experienced similar problems or has suggestions for troubleshooting.
This has been a bit of a learning curve, but I’m hopeful that with some trial and error, I can get these thermostats working as intended. Thanks in advance for any insights!
