First of all, it has been a pleasure to be part of this. My ESDK is still up and logging data, plan is to get a full data set for a year and then compare with the weather to see any correlations.
I have seen that some features like: formaldehyde, NO2 and NRD detection (this one, in my location, is really great for Radon). Would it be possible to get these sensors in the future? I'm committed to a long-term collaboration.
