Hi Arne,
yes, I misunderstood the current reading in the map - though it would be great to use Grafana as a dashboard, on per station SNR values. With wsprdaemon-data we have the advantage that although the call of the spotting station is the same, we can see the snr per kiwi-rx hardware (receivers) - in my case kiwi3 or kiwi 6 in above example...

regards,
Ulli, ON5KQ
