It carries a 5-year warranty, runs on USB-C or batteries, and works with Alexa, Google Home and Home Assistant. The Ecobee Smart Thermostat Premium is the lower priced, better rated device and does something no monitor can: it controls the heating and ventilation it measures, with CO2, VOC, temperature, humidity and occupancy sensing, a 4 inch colour touchscreen and support for Apple Home and SmartThings too.

What the differences mean

Sensors

The Airthings View Plus measures radon, PM2.5, CO2, VOCs, temperature, humidity and pressure. The Ecobee Smart Thermostat Premium covers CO2, VOCs, temperature and humidity and adds occupancy, but has no radon or particulate sensor, so smoke and dust are invisible to it.

Acting on the air

The Ecobee Smart Thermostat Premium is a thermostat, so it can run the heating and ventilation it measures and reminds you to change the HVAC filter. The Airthings View Plus only reports, and acts through Alexa, Google Home or Home Assistant.

Installation and power

The Ecobee Smart Thermostat Premium is hardwired into the HVAC system. The Airthings View Plus plugs into USB-C or runs up to 2 years on six AA batteries, and goes anywhere in the house.

Platforms

Both work with Alexa, Google Home and Home Assistant. The Ecobee Smart Thermostat Premium also supports Apple Home and SmartThings, which the Airthings View Plus does not.

Alerts and warranty

The Airthings View Plus has humidity alerts and a 5-year warranty. The Ecobee Smart Thermostat Premium measures humidity but cannot raise its own humidity alert, and carries a 3-year warranty.

What owners say

Airthings View Plus owners value having radon alongside CO2, VOCs and PM2.5 in one good-looking unit, and say the data changed how they live: CO2 climbing overnight in a sealed home, frying spiking particulates, radon moving with weather and HVAC. Several cross-checked its PM2.5 against outdoor reference sensors and radon against traditional tests and found good agreement, and they praise the web dashboard, CSV export and fast support replacements. Their complaints are the premium price, a CO2 sensor that drifts high without fresh-air recalibration, alert thresholds that cannot be customised, an unlit screen and a 7-day calibration period.
