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.
I have had to order these type of sesnors for mobile handheld units before. The units themselves are more than this unit and the replacement of these two sensors would tally the difference between units.
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.
