Stupid system
You need to disconnect from your private wifi network and connect to sanutal ventilation wifi system (actually very limited in terms of distance, literally a few meters) to be able to control it. Most of the times it doesn’t work / respond to commands and I have to literally unplug it and the. Re plug it. Defined needs improvement….or alternative had to be provided i.e. to start it manually!!!! Which is not possible..:
