I have to wonder if Wyze hasn’t quietly prevented v1 sense devices from being added to accounts. Here on their own forums, Reddit, and other home automation web sites you see posts about v1 sensors mysteriously going dead even though they exhibit normal behavior. So even if you were able to try to flash a Mac address back on to them would you be able to add them to your account? My experience suggests no. I’d be curious to know if anyone has been able to add a v1 sensor to their account recently?
All my v1 contact and motions sensors went dead on the same day, every single one of them stopped working at the same time on the same day even though they all had good batteries and I never got any low battery warning in the app for any of them. All of them were of different ages from a few months to just shy of a year old. Wyze support told me to delete them all and try to add them back and that’s where it all went wrong. I cannot add any of them back to any of my three usb bridges no matter which of my six cameras I try to use. All of the sensors, bridges, and cameras indicate all is good - correct LED behavior on sensors, bridges, and cameras.
After many support requests where I was given the scripted answers are v1 not supported, we don’t have any replacement v1 sensors for which to send replacements by some miracle Wyze located some and sent me a few replacement sensors and guess what, I can’t add any of them to my app either whether I try an iPhone or an android phone. The problem follow the sensors to any network where I try to experiment with them.
I keep arguing with Wyze about this but they’ve dug in their heels and refuse to address this massive defect with any sane remedy. They just keep saying “they are out of warranty now, sorry, best we can do is $15 in store credit for your 20+ sensors that mysteriously stopped working all on the same day”.
Strangely enough I did a quick experiment with the Home Assistant software and was able to join one of my v1 motion and v1 contact sensors to Home Assistant! So the sensors are fine! My usb bridges are fine! Which only leaves my Wyze account or some problem with the Wyze back end specific to my account. Weird huh?
I suspect Wyze has been been either lazy or dishonest with me about this. and that’s why I haven’t bought any more of their products and will continue to complain here until the day I have replaced all of my Wyze devices with something else or no longer have any reason to troubleshooting anything from Wyze.
Good luck with your re-programming experiment, I hope you’ll post details about it if it works, I know there are many people out there with bricked sensors who might want to try to resurrect them.
