Full details →Who the Yale YDM 4109A+ Smart Mortise Door Lock with Fingerprint, PIN, RFID and Key is for
Buy it if: Anyone fitting a smart lock to a standard Indian mortise door who wants it to work without any network.
Avoid it if: Anyone expecting remote access out of the box -- the Wi-Fi module is sold separately.
Who the Aqara Presence Sensor FP2 mmWave Multi-Zone Occupancy Sensor is for
Buy it if: Anyone whose lights keep switching off on a person sitting still, and anyone wanting room-level presence rather than motion.
Avoid it if: Anyone wanting a battery sensor -- this needs permanent USB power -- and anyone on a tight budget, where a PIR does most of the job.
