A "Last Motion" Sensor in Home Assistant: Per-Room Timestamps with input_datetime
A reusable Home Assistant pattern: one input_datetime helper per motion sensor that records the exact time of the last movement — the data foundation for presence heuristics and a tidy "last seen" dashboard, no expensive mmWave sensors needed.
