Install it on this device for its own icon and a window without the browser bar. Nothing is downloaded from a file host — your browser does the installing.
Your browser has not offered to install this yet. In Chrome or Edge, look for the install icon at the right of the address bar — or open the menu and choose Install HouseControl.
Every device
Android, iPhone, Windows and Mac. One install, the same screens.
