I have the same problem with the bind error issue as everyone else here. Since I have been trying to set mine up using my Samsung S20 running Android 13, BT ver 5.0. When you stated that you used your wife’s iPhone and that was how you solved the problem I thought since I am not an iPhone user I would try my Samsung Tab S7 FE tablet running Android 13, BT ver 5.2. Same binding error. Then I tried my Motorola e5+ running Android 8.0, BT ver 4.2 and “BAM” it worked on the three switches that I just wired in. So, the difference between the iPhone, Motorola and Samsung could be the Bluetooth version it is running, the Android version or the phone manufacturer. Maybe the Wyze development team could look into this if they are monitoring this thread.
