Airthings Wave Plus vs Ecobee Smart Thermostat Premium

Ecobee Smart Thermostat Premium wins overall with its higher owner rating, Wi-Fi connectivity, color touchscreen, six-platform support and HVAC control. Airthings Wave Plus keeps the longer 5-year warranty, richer alerts and unique radon plus pressure sensing, on a battery-powered unit you can place anywhere.

Role. The Ecobee is a wired wall thermostat that monitors air quality (VOCs, CO2, occupancy, temperature, humidity) and acts on it through your heating and cooling. The Airthings is a portable six-sensor monitor whose headline capability is radon, something no Ecobee measures. One controls your climate; the other audits your air.

On top of CO2, VOCs, temperature and humidity, the Airthings Wave Plus adds radon and atmospheric pressure, while the Ecobee Smart Thermostat Premium adds occupancy sensing and, crucially, the ability to run fans or ventilation when air quality drops.

The Ecobee Smart Thermostat Premium: it supports Google Home, Alexa, Apple HomeKit, Samsung SmartThings, Home Assistant and IFTTT. The Airthings Wave Plus covers Google Home, Alexa, Home Assistant and IFTTT, and is Bluetooth-only, needing an Airthings Hub for remote data.

Choose Airthings Wave Plus if radon matters in your home or you want a battery-powered monitor you can move between rooms, with CO2, VOCs and pressure included and a 5-year warranty behind it.

Choose Ecobee Smart Thermostat Premium if you want one wall-mounted device to manage comfort and keep an eye on VOCs, CO2 and occupancy, with a premium touchscreen, dual-band Wi-Fi and compatibility with every major smart home platform.
