Accessory is not responding on Home app

[roeekl]

Hi, I have a problem where after few commands, the accessory stops responding on the home app and homebridge. Here are the logs that was shown at the moment it stopped respond:

From that moment the only solution is to restart homebridge, and reinstall the accessory.
