You can send weather data from Domoticz to Weather Underground. So use Domoticz to collect data from your (my)sensors.

@TheoL I'm going to build de outdoor solar weather station, also! Busy with ordering the parts on Ebay.

RFLink and Domoticz work great together with klik aan klik uit and my Alecto WS 3500 weather station. Also receiving weather sensors from my neighbours. Next project is building Mysensors.org sensors. RFLink works alsoas an gateway.

@5546dug Have you a wiring diagram?

Please add an wiring diagram. Especially for the solar panel, battery and connection to the Nano.
