2026 verdict
Long-term radon averages are not what a wall control measures, yet the Ecobee Smart Thermostat Premium is still the overall recommendation.
It is the better reviewed of the two, with CO2, TVOC, occupancy, temperature and humidity on a 4 inch color touchscreen, plus Google Home, Alexa, Apple HomeKit, SmartThings and Home Assistant. The Airthings 2989 View Radon is the one that measures radon, on e-ink, over 2.4 GHz Wi-Fi, with six AA batteries rated for about 3 years or USB-C, humidity alerts and a 5 year warranty. It can also hub other Airthings meters. Buy the Ecobee Smart Thermostat Premium to tie room gases to the heating. Buy the Airthings 2989 View Radon if soil gas is why you started looking.

What the differences mean
Radon versus CO2 and VOCs
The Airthings 2989 View Radon measures radon, temperature and humidity. It does not measure CO2, TVOC, particles or carbon monoxide. The Ecobee Smart Thermostat Premium measures CO2, TVOC, temperature, humidity and occupancy, and it does not measure radon. The sheet gives the thermostat more sensor rows. It does not give it the gas a basement buyer came for.
Where it has to live
The Airthings 2989 View Radon can run about 3 years on six AA batteries or plug in over USB-C, so a basement shelf is enough. The Ecobee Smart Thermostat Premium is hardwired into the HVAC wall and has no battery. One follows the radon from room to room. The other stays on the thermostat wires.
Platforms
The Airthings 2989 View Radon works with Google Home, Alexa and Home Assistant over 2.4 GHz Wi-Fi and Bluetooth, and its SmartLink radio can hub other Airthings devices. The Ecobee Smart Thermostat Premium adds Apple HomeKit and SmartThings, uses both 2.4 GHz and 5 GHz Wi-Fi, and does not speak Matter. Apple Home is the split that actually changes the shopping list.
Alerts
The Airthings 2989 View Radon alerts on temperature, humidity, air quality and a low battery. The Ecobee Smart Thermostat Premium alerts on temperature and air quality, and not on humidity, which it still measures. A damp basement gets a push from the radon meter and silence from the thermostat.
Which one to buy if
- you want radon on Wi-Fi with a screen you can glance at
The Airthings 2989 View Radon measures radon, shows it on e-ink, and alerts over 2.4 GHz Wi-Fi, including humidity and a low battery.
- carbon dioxide and VOCs should change how the house is ventilated
The Ecobee Smart Thermostat Premium reads CO2, TVOC and occupancy on the hardwired control that runs the heating, which the radon meter cannot do.
- the house runs on Apple Home or SmartThings
Those two platforms are on the Ecobee Smart Thermostat Premium. The Airthings 2989 View Radon lists Google Home, Alexa and Home Assistant, and not Apple HomeKit or SmartThings.
- you already own other Airthings sensors that need a hub
The Airthings 2989 View Radon can act as a SmartLink hub for other Airthings devices. The Ecobee Smart Thermostat Premium does not join that radio.

What owners say
Owners of the Airthings 2989 View Radon pick it over a Bluetooth-only puck because they can check radon from anywhere, read the e-ink screen at a glance and get weekly email reports. Several describe levels swinging by room, weather and season in a way a single lab test missed, and a few credit the meter with showing that a mitigation fan had stopped. Battery life on the AA cells is part of that praise, along with moving the unit from room to room. The sour notes are a minority: a unit that sat near zero, two meters that never agreed on radon, and support that felt like a script before a replacement was offered. Others report the opposite, a fast swap, so the service stories do not line up.
Price history compared
Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
