I start using Arigardient with HA and I like it a lot. I have one question - is there any calibration for particles concentrations? It looks like it running really low (0-1 ug/m3)
As a future improvement I believe using POE T-ETH-Lite – LILYGO® can be really interesting (I am planning to use airgradient in every room in a new house
Another addition, I believe, light sensor can be very handy as well (Airthings has it)
Thanks
