When some devices have been without battery for a while (weeks) i always have to delete it, then re-add it again. especially for my Aqara temp sensors. When i do this i loose all my temp stats from homey. Is there really no other way to make it communicate with homey again?? ---

Don’t delete it! Just pair it again, it responds with “device is already added”, restart app, done. ---
