Bring precise environmental sensing into your smart home setup with this Zigbee temperature and humidity sensor built around a Swiss Sensirion chip. Temperature accuracy of plus or minus 0.3 C and humidity accuracy of plus or minus 2% place this unit in a different class from standard consumer hygrometers. The Zigbee protocol ensures broad compatibility with Echo 4th Gen, Echo Plus, Echo Studio, Eero 6, SmartThings, Home Assistant, Aeotec, Homey, Hubitat, and the Third Reality hub ecosystem. Adding the optional Third Reality MZ1 bridge extends compatibility further to Apple HomeKit and Google Assistant via the Matter standard. At 3.62 x 3.11 x 0.79 inches, the sensor sits flat against any wall or surface.
