Hi. No unfortunately you cant set it in developer mode in the mi home app. There is no About menu like there is with the v2 gateway. Happy to be told differently but have had a good look and cant find anywhere in thg e menu systems to activate it. I have had a v2 gateway so I know where I'm locking.
I recently bought this AirBnk M500 lock and was unable to integrate this with home assistant. One of reasons I am considering switching to Hubitat.
So, can you confirm this lock integrates well with Hubitat?
This lock doesnt integrate with Hubitat. It has it's own app AirBnk which is pretty flaky. Its Tuya based so HA wouldngive tou better integration. Not come across anyone that's managed to flash this with Tasmota either
