Home Connect Bosch Washer and Dryer

Robert-N · May 25, 2026, 8:36am

Hi all, I had a half year ago 2 new machines and succesfully added them in HA, with de home connect integration.
But a few days ago, suddenly the washer is unavailable in HA. In the home connect app the machine is doing fine, everything connected and so on.
Also my dryer is doing fine in both HA and home connect.
I cant delete the washer alone, I tried some things but I stays offline. Does someone has an idea whats going on here and how to fix it?

I rebooted HA, the washer and so on. Everthing seems to be up to date.

Well, my home connect app is connected. Only 1 of the 2 machines appears to be not available.
