I have been testing a pair of Centralite temp / humidity sensors and the outcome thus far has been excellent. I have tried Zooz and Sonoff and had less than desirable results with both. Very impressed with the out of the box accuracy on the Centralite devices (zigbee) less than 1 degree from the reference thermometer - just a share to my fellow HE friends. j
Centralite stuff is usually pretty solid. I've also liked the MOES humidty/temp sensors. My favorite though are still NYCE
