@paravis, now sure about ET level yet, it is still at Zero and I was expecting a value today. It updates at end of “archive” period so I might need to change something or simply WU data is lacking. More research required.
Eventually I’ll plan on having the weather station uploading to local Weewx and not WU, local Weewx will then upload to WU. Then that way if the internet/cloud service is down I’ll still be kicking :). For now it was simpler to sniff the traffic because no changes required to devices.
