Airgradient's popular indoor air quality sensors are the first devices of their kind to be officially certified as "Works with Home Assistant". These open-source devices do not require an internet connection and enable local automation with air purifiers, air conditioners, or humidifiers and dehumidifiers.
Sure… But does a typical household need this. My point was that I’m not sure that $170 for these sensors makes sense for me. And I suspect that most people are in the same boat as me. Maybe a sane answer for someone truly interested in the CO2 sensor and such for say 5 rooms is one of these in a central room and Vindstyrkas in the others. Otherwise you’re talking about $1150… Which most people just aren’t going to do.
