Wyze Thermostat - Alexa says it has set the temp, but temp is not actually changing

This is a strange issue… the Alexa integration with our Wyze thermostat has been working great up until recently. I’m not sure how long this has been going on because it sounds like everything is fine.

Here is the example of how I discovered the problem:

  • Temp was set low for sleeping (64)
  • Said, “Alexa, turn up the temperature”
  • I heard Alexa respond “The heat is set to 66”
  • Said again “Alexa, turn up the temperature”
  • I heard Alexa respond “The heat is set to 66”
  • after doing that a few more times, I tried saying “Alexa, set the thermostat to 70”
  • I heard Alexa respond “The heat is set to 70”

At this point I opened the “Wyze” app and noticed the temperature setting didn’t change at all (was still at 64). I noted that it was in “Home” mode, and I could SUCCESSFULLY change the set temperature with the Wyze app.

At this point, I disabled the Wyze skill in the Alexa app on my iPhone, then re-enabled it and re-detected devices.

  • same experience - Alexa says that it changed the temperature even though nothing happens.

Now I walk over to the thermostat and reboot it, by removing it from the wall and re-inserting it.

Tried everything again and it STILL won’t let Alexa change the temperature, even though Alexa thinks that it did.

What could be the problem?

Had that issue until today and it works again.
