Wyze thermastat will not show the number 7 shows every other number but that. For 2 weeks it did show the number then just stopped. If it’s 77 degrees in the house it shows blank on one screen and when cooling shows 2 rectangles. If 78 degrees it shows the number 8 or a rectangle and the number 8.
First, I’d pull it from it’s mount and push it back in. That should power-reset it. Then I’d call Wyze Support if the problem persists:
There are many ways to contact Wyze. Their phone number is (206) 339-9646, or you can chat with an agent or create a ticket on the support site.
They’re open for support between 4 am-8 pm PT Monday through Friday, and 8 am-4 pm PT Saturday.
