Hi
Not complex… but needs more “channels” (temperature, cpm, voltage…)
think the easier way is that the device send something like that :
– channel name, ex. Cs137
– activity value
– unit, ex. Bq
I don’t know what you plan to display on your map, if you restrict to air or if you plan to add rain (I think that in my country, rain has drop down elements from Tchernobyl).
Best regards
