With Homey Pro 13.3.0 the Bosch System is losing the matter connection after some minutes. A restart of Homey works only some minutes also. Anyone else here facing this issue ?

Problem resolved. Reason was a break in power outage, wich stopped the matter connection. Had to delete the controller in Homey and set it up again. Flows have to be repaired also. This was the most annoying thing in this case. Bosch has adressed this issue in their Juli 26 update. Hope it fix this for possible power outages or restarts of the controller in future.
