Key differences between Aranet Radon Plus and Third Reality Smart Air Quality Sensor

A summary of selected recorded differences between these air quality monitors. Check the full specification table below for details and conditions.

Feature differences among your selected devices

Bluetooth (connectivity): Aranet Radon Plus — Yes; Third Reality Smart Air Quality Sensor — No.
Screen (display): Aranet Radon Plus — Yes; Third Reality Smart Air Quality Sensor — No (No display: readings are only visible in the hub app. The front carries a single pairing button and the sensor intake grille.).
Automations (features): Aranet Radon Plus — No; Third Reality Smart Air Quality Sensor — Yes (Automations run in the hub with no cloud routing, which is what THIRDREALITY calls Automatic Air Rules.).
Alexa (integrations): Aranet Radon Plus — No (Aranet sensors are Bluetooth instruments read by the Aranet app or the Aranet PRO base station, with no Alexa skill); Third Reality Smart Air Quality Sensor — Yes (Pairs straight to Echo devices with a built-in Zigbee hub, including Echo (4th Gen), Echo Plus (1st and 2nd Gen), Echo Studio, Echo Show 8 (3rd Gen), Echo Show 10 (2nd and 3rd Gen), Echo Hub, Eero 6 and Eero Pro 6.).

Specifications to check side by side

Zigbee (connectivity): Aranet Radon Plus — No; Third Reality Smart Air Quality Sensor — Zigbee Hub required (Zigbee 3.0 end device. THIRDREALITY lists Home Assistant (ZHA and Zigbee2MQTT), SmartThings (2015/2018), Aeotec, Hubitat, Homey Bridge and Pro, the Third Reality Hub Gen2 Plus and Echo devices with a built-in Zigbee hub as the coordinators it pairs with.).
Apple Home (integrations): Aranet Radon Plus — No; Third Reality Smart Air Quality Sensor — Smart Bridge MZ1 required (Not a HomeKit or Matter endpoint on its own. THIRDREALITY's compatibility chart for this sensor reaches Apple Home (HomePod, HomePod mini, Apple TV) through its own Smart Bridge MZ1, the Zigbee to Matter bridge it sells separately.).
Google Home (integrations): Aranet Radon Plus — No; Third Reality Smart Air Quality Sensor — Smart Bridge MZ1 required (Google Home has no Zigbee radio.
