Thanks for the suggestions. I have tried reinstalling the entire app (which included clearing app cache), but that didn’t work. I wasn’t using BLE for any other devices. I only have 2 GHz broadcasting from my router.
I have 4-5 other switches that were installed a couple of years ago. Those didn’t have this error, and have been working fine after installation. The bind switch error I’m experiencing is on unused switches purchased years ago. If I had to guess, it seems like somewhere the app became incompatible with the “old” (but unused) switches.
There are a number of threads from years ago about this error, but I’m experiencing this today. So those issues were apparently not fully resolved.
I haven’t contacted Wyze Support yet, but since there doesn’t appear to be a public solution, I’ll try that next.
