The physical hardware is high quality, as with all of Netatmo’s products. You could easily pair it with an air filter to automatically turn it on if the quality turns south using a HomeKit automation. I especially appreciate being back to track air quality in my living room. Both of these modules are exposed inside of HomeKit so you can track temperature, CO2, air quality, and humidity. The Netatmo Weather Station includes an indoor module and an outdoor module. I’ve only used one of Netatmo’s products previously, and it was their indoor HomeKit camera, which has a very premium build quality.
