Eufy Smart Lock (T8520) not working

Third party integrations
1

I’ve added my door lock using the Eufy Security integration. I can see the entities in Home Assistant, but I’m unable to Lock or Unlock the door.

When I click on one of the actions I get the following error:

Failed to call service lock/unlock. {‘type’: ‘result’, ‘success’: False, ‘messageId’: ‘device.set_property.c4220f1e3731483e9818ee9ec24bbfb6’, ‘errorCode’: ‘unknown_error’}

I’ve added the lock to the Eufy app and shared it with the account I use for Home Assistant. I have a doorbell working this way as expected. Anything I’m missing to get the door lock to work?

any logs from add-on?

Do these help? I just replaced my IP in the below.

Did you end up getting any info on this? I just tried to update from 2.9.0 to 6.1.1 and the same thing happened to me and I had to go back to 2.9.0

Unfortunately not. Still not too sure why my other devices seem to work, but for whatever reason I can’t lock/unlock this one. I can see it and even get the battery level.

@yesterdayshero I have the same issue over here and just logged the issue on GitHub: Smart Lock Touch (TR8520) is not locking/unlocking · Issue #681 · fuatakgun/eufy_security · GitHub

I’ve still had no luck, but noticed your issue has been marked as closed :frowning:
