WIFI Weather Station Gateway: Receives Ecowitt and Ambient Weather sensor data from external sensors (sold separately): outdoor temperature and humidity, multi-channel (max 8) temperature and humidity, rain, wind, soil moisture(max 8), PM2.5(max 4) and so on; Allowing you to remote monitor weather data on our free WS View APP
Studing a bit their API to access the data over a TCP “pull” connection
Cumulus MX source implemented it and their code is opensource
Specific part about the GW1000
and an extract to showcase how elegant is their solution (not):
