The homeseer HSM 200 is a plug-in model with an indicator light that can be one of seven colors. Reports motion, temperature, and light level, although the light level reading is weird, it’s obviously intended just to have it function as a night light.
Quite a few people are using it. This one is even more expensive than the Aeotec, but the indicator light can be a nice feature.
It Also functions as a Z wave repeater, one reason people often choose plug-in devices. The Aeotec also does when it’s plugged in, but not when running on battery. ( battery operated devices generally do not repeat because it would use up too much battery life.)
