Aqara TVOC Air Quality Monitor vs Ecobee Smart Thermostat Premium

The Ecobee Smart Thermostat Premium wins this comparison, leading on owner rating, warranty, connectivity, integrations and sensors. It is a smart thermostat with a built-in air quality monitor, so it does far more than the Aqara. The Aqara TVOC Air Quality Monitor wins on price and offers more alert types, but it is a single-purpose VOC sensor.

Their core purpose. The Ecobee Smart Thermostat Premium is a wired smart thermostat that also senses VOCs, CO2, temperature, humidity and occupancy on a 4-inch color touchscreen. The Aqara TVOC Air Quality Monitor is a small, battery-powered air sensor that only measures VOCs, temperature and humidity and shows them on an e-ink screen through a Zigbee hub.

The Ecobee Smart Thermostat Premium connects over dual-band Wi-Fi and Bluetooth and works with Google Home, Alexa, HomeKit, SmartThings, Home Assistant and IFTTT with no hub. The Aqara TVOC Air Quality Monitor runs on Zigbee and needs an Aqara hub, after which it reaches HomeKit, Google Home, Alexa, Home Assistant and IFTTT but not SmartThings.

Two: price and alerts. The Aqara TVOC Air Quality Monitor is much cheaper and battery-powered, so you can place it anywhere without wiring, and it offers temperature, humidity and air-quality alerts. The Ecobee Smart Thermostat Premium provides temperature and air-quality alerts but no dedicated humidity alert, and it must be hardwired like any thermostat.

Anyone who wants heating and cooling control plus air sensing in one device. The Ecobee Smart Thermostat Premium senses VOCs, CO2, temperature, humidity and occupancy, has a color touchscreen, works with every major smart-home platform, and includes a three-year warranty. It requires standard thermostat wiring, so it is not a portable, place-anywhere monitor.

People who want a cheap, movable VOC and climate sensor rather than a thermostat. The Aqara TVOC Air Quality Monitor runs on batteries, shows VOCs, temperature and humidity on an e-ink screen, and works with HomeKit, Google Home, Alexa, Home Assistant and IFTTT through a Zigbee hub. It does not control your HVAC or measure CO2.
