I installed some window sensors at a friend’s place and showed him that it just detects a magnet. Since he wants his smart Home completely local, I thought about how to notify Home Assistant, that someone came home or is somewhere else. My Idea is now do take one Window Sensor per Person and put them on a 3d printed Key rack. Every key gets a magnetic hanger and his own position. Now HA knows who is at home and who is not and can start automations e.g. Do you have other ideas how to misuse Sensors, lights etc. for some practical purposes?
