Hi David,
I just checked that Wiki that you linked on supported devices and wonder if the Ecowitt stations section should be expanded a bit (don't know how that is done

)
GW1000 WiFi gateway is correctly listed as supported.
The GW1000 is an Ecowitt device, but not a weather station, that can receive from Ecowitt station and extra sensors (must be matching MHz). The device is connected to a computer USB only for power source and is wireless for receiving station and extra sensor data and then WiFI to send to Ecowitt site. Cumulus can access the data through its TCP/IP settings. The GW1000 is not a datalogger so there is no catch up at a Cumulus or computer restart.
While the GW1000 is not a weather station as such, it does have built-in inside temp and humidity and pressure sensors
Possibly Wiki could say "All stations used in conjunction with GW1000 WiFi gateway"
