I think I may have solved the flashing blue light issue. See if you have an access point with the name “wyze_station_xxxxxxx” in your wifi list. If you do, force close the Wyze app. Then, switch to that AP. After that, reopen the Wyze app. It should act like the station is in travel mode. Tap “Exit” in the upper right corner of the screen and then press “SYNC” on the base station. The blue light should finally stop blinking.
What I think happened is that something in the update process with the app put the thing in a pseudo travel mode when you know you didn’t set it.
