The Sonoff SNZB series covers nearly everything needed day to day: temperature and humidity, motion, door and window opening, water leak and even human presence sensors. Most of them communicate over ZigBee, so the home needs a gateway — without one the sensors will not show up on your phone. TP-Link Tapo devices run in their own ecosystem instead. A presence sensor differs from a motion sensor in that it also notices a person who is standing still.
