If you’re trying to view signal strength from an Android device, it’s bugged and will always show no bars (hollow) for all cam types except WCO cams from the base station’s point of view or when using a old version of the Wyze app. iOS devices seem to have no problem displaying signal strength for all cam types except WCO cams. Examples:
v2 cam from an Android device:
Same v2 cam from an iPhone:
v3 cam from an Android device:
Same v3 cam from an iPhone:
Several of us have reported the problem and submitted logs. It must be considered a low priority item as it’s been around for a year.
