Why not to show airgradient map with color gradient (heatmap) like IQair ?
And why not to add also NOx, temperature, humidity, VOCs instead only CO2 and PMx ?
What exactly do you mean with heat map? Can you share a screen shot?
Is it normal that on AirGradient Map I can see on PMx and CO2 ? How can I see on that map all other data form the sensors purchased ?
