Any tablet with Android 7 or higher will work.
Wyze app is still available in Google play for any device running Android 7 or higher, but is no longer available for those running anything lower than Android 7.
If you have or get a tablet running something lower than Android 7 and cannot upgrade past Android 7, then you will have to get an older version of the Wyze app off an APK mirror site, and the older Wyze app version may not have fully function with everything, but some things may still work depending on the device in question and what you are trying to do.
Just check to make sure any tablet you consider runs Android 7 or higher and you’ll be fine. That basically means any tablet created after August 2016 should work fine. If you buy one off ebay or Wish or Alibaba or some knockoff site or generic brand or something then you might get one that is too old, verify the OS version first and you’ll be fine and the Wyze app will be in Google Play.
