Looks like an upside down THIRDREALITY Night Light... but it also does mmWave and air quality. I'm a sucker for indicator lights, but price is making me hesitate buying one right now. That, and someone needs to make a driver for it. @kkossev ?
Yeah, I searched the community for ThirdReality Sensor R3 first and nothing came up, and I also searched for just sensor R3. I guess that searched missed that post last week with the more general title about just a "Third Reality" Zigbee multi-sensor.
