I am looking for a way to determine if a body (maybe at rest or not moving much) is in a room. My sons don't turn off lights/fans in their bedrooms, and I want a way to do that. Problem is that with PIR (and even PIR/Microwave dual setups), they don't move enough to trigger it reliably. My one son works odd and varying shifts, so setting a schedule for it does not work. My question is: Is there a Microwave (or equivalent) only detector that will mount in the same area (up in the corner of the room), or can I mod something like the Honeywell Dual detector to alert on MW only (I *think that might be sensitive enough), or is there a better solution? I have the wiring run to the upper corner of the room, so whatever I get needs to mount there too, and be powered by the Konnect 12v module.
