One of my two Xiaomi contact sensors now shows offline post migration, another of the same type works fine. Both use a custom DTH and worked for 1yr+ pre-migration.
I’ve tried removing the sensor’s battery to repair, and also power cycled my (v2) hub (removing the batteries) – no joy. I’ve tried moving the device to within 10’ of the hub as well.
I’ve seen related posts saying this can not be a new app issue, but in any case I’d like to fix “using” the new app given I’ve migrated.
