Sensors & presence

Because a motion sensor only sees movement. In rooms where people sit still, an office, a reading chair, a dining room, we use millimetre-wave presence sensors instead, which keep reporting that someone is there. Choosing the right sensor for the room is what makes automatic lighting tolerable to live with.

On the controller in your house. Sensors report over Thread, nothing is sent to a manufacturer's cloud, and you can read every value in the app and in the controller's own history. That history is what lets anyone answer why a room was cold or when a door was last opened.

Where the hardware supports it, yes. An integrated detector becomes an input like any other, so the rest of the house can respond to it instead of leaving one unit beeping in a hallway. Some detectors cannot be integrated at all. We look at what you own during the survey and say which ones qualify.

A large part of the survey is exactly that, because good automation is mostly good sensing. We walk the house and note where people actually sit, which doors matter, which rooms run cold and where air quality is worth measuring: CO2, particulates and VOCs. The positions end up in the handover pack.
