I have tried several times, both with group two and group four, but to no avail. I’m trying to associate it with an Everspring HAN02 on/off switch, that’s controlling the light in the mirrors in the bathroom. They should always come on when the door is opened, even if the controller is dead. I see there are a billion different configurations for the device, but I hoped that a simple assosiation would work. Nothing happens, even if I wake the sensor manually. Maybe somebody has a good understanding of these things and can tell me what to do?
