Ecowitt has released a firmware v2.2.6 for the GW1100 where the measurement time (dateutc) is URL-encoded when sent via the custom server in Ecowitt format.
So “dateutc=2023-08-30+10:41:11” now becomes “dateutc=2023-08-30+10%3A41%3A11” - so the colon is output as “%3A”.
Is PWSDashboard prepared for this? I’m not sure if it’s an (temporary) oversight by Ecowitt or the future format (also for other Fine Offset weather stations). An enquiry is underway with Ecowitt. But we should be prepared.
