Is it based on it or a complete rewrite?
How about local connection from openHAB to the BSH appliances?
From reading the manual it seems, that the Bosch app can live without a permanent internet connection.
I asked similar to @FanFan one day, but did not get an answer yet:
Since I don’t have my BSH appliances (yet), I can’t test/verify the local operation myself.
Would be nice if you can try and shed some light on this
