I stumbled over this community when looking for Air Quality Sensors for my home automation. I read a bit about the project checked out the map and like the idea of it, so that I would gladly contribute my data as well. I checked the “build your own sensor” page and saw that you are offering an ESP firmware that basically is ready to go.
I’m just missing one info. I suppose the firmware posts the data to some end point of the project to generate the grafana visu. But can I also configure it to post it to my local MQTT Server as well? Or is it only meant to post it to your servers?
