Navien Smart

Control and automate your Navien AirOne — ventilation, dehumidifier and air purifier — and Navien sleep mats. This is an unofficial, community-built app and is not affiliated with Navien. The AirOne gives you power, operating mode (auto, ventilate, ventilate + dehumidify, dehumidify, purify, cooking, sleep, bypass), fan speed and a target humidity, alongside air-quality readings — PM1.0, PM2.5, PM10, CO₂, TVOC, radon, temperature, humidity, an overall score and filter usage — with good/bad grade labels for TVOC and radon. A paired AirMonitor is added as its own sensor device, and sleep mats expose power, per-zone temperature and heat level. Every reading can drive an automation as a condition, and operating mode, fan speed, power and target humidity as actions. Sign in once with your Navien Smart account in the app settings; only newer AirOne units (model code 1000 and above) are supported. Boilers and wall pads are out of scope — for those, please use the official Navien Smart app by navien kd.
