I wanted to know what the airquality was outside my house, but this was hard as multiple houses here use woodstoves, so i needed to compare the quality of air over multiple points to have a proper baseline.
In short, i now run a virtual m2m lora-wan provider for 5 sensors around my town that feed into homeassistant using mqtt, all sensors are battery powered with solarpanels and powered by esp32's.
