2026 verdict
Crawlspace radon builds with no smell and no color change, yet the Ecobee Smart Thermostat Premium is the overall recommendation on this sheet.
It is the better reviewed of the two, with a color touchscreen, dual-band Wi-Fi, and CO2, TVOC and occupancy on top of temperature and humidity, across Google Home, Alexa, Apple HomeKit, SmartThings and Home Assistant. The Airthings 2950 Wave Radon is the meter that sees radon, on two AA batteries rated for about 1.5 years, with a wave-to-check light, a 5 year warranty and humidity alerts. It has no screen and no Wi-Fi of its own. Choose the Ecobee Smart Thermostat Premium to ventilate from the wall. Choose the Airthings 2950 Wave Radon for the gas under the floor.

What the differences mean
The gas each one can see
The Airthings 2950 Wave Radon measures radon, temperature and humidity. The Ecobee Smart Thermostat Premium measures CO2, TVOC, temperature, humidity and occupancy, and no radon. More rows on the thermostat do not add a radon sensor. If the crawlspace is the reason for the search, the Wave is the instrument, whatever the overall badge says.
Screen and how you check it
The Airthings 2950 Wave Radon has no display. A wave of the hand lights a green, yellow or red ring, and the numbers live in the app over Bluetooth. The Ecobee Smart Thermostat Premium has a 4 inch color touchscreen at 540 by 540 and stays on 2.4 GHz and 5 GHz Wi-Fi. One asks you to walk up and wave. The other is already on the wall.
Power
The Airthings 2950 Wave Radon runs on two AA batteries for about 1.5 years and can join an Airthings hub over SmartLink for always-on data. The Ecobee Smart Thermostat Premium is hardwired and has no battery. A crawlspace without a convenient outlet is a natural place for the radon meter and a bad place for the thermostat.
Alerts and warranty
The Airthings 2950 Wave Radon alerts on temperature, humidity, air quality and a low battery, and the warranty is 5 years. The Ecobee Smart Thermostat Premium alerts on temperature and air quality only, with a 3 year warranty, and it does not alert on humidity. The longer warranty and the humidity alert both sit on the radon side.
Which one to buy if
- radon in a basement or crawlspace is the only question
The Airthings 2950 Wave Radon measures radon on AA batteries, with a wave-to-check light and humidity alerts. The thermostat has no radon sensor.
- a stuffy room should change the heating on its own
The Ecobee Smart Thermostat Premium reads CO2, TVOC and occupancy on the control that runs ventilation. The Airthings 2950 Wave Radon cannot see those gases.
- you want the reading on a color screen without opening an app
The Ecobee Smart Thermostat Premium has a 4 inch color touchscreen. The Airthings 2950 Wave Radon has no screen, only a colored ring when you wave.
- the house standard is Apple Home
Apple HomeKit and SmartThings are on the Ecobee Smart Thermostat Premium. The Airthings 2950 Wave Radon works with Google Home, Alexa and Home Assistant only.

What owners say
Owners of the Airthings 2950 Wave Radon contrast it with a one-time charcoal kit: the app keeps a history of how radon rises and falls with rain, an empty house or a closed-up week, and several say the number landed close to a professional lab test after the 48-hour acclimation. Watching the level drop once a mitigation fan came back on is the story they repeat. The wave-to-check ring, a one-minute setup and battery life measured in years get the same praise. The complaints cluster on two things. It syncs when the app is opened nearby, not in the background, and Airthings support is described as slow and chat-only. A minority also report a false high spike or two units that did not agree.
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.
