The reason I bought my Rasberry PI was to use it as a weather station, initially I only used a Davis Vantage Vue Weather Station but I have recently extended that with an Ecowitt GW1000 WiFi Weather Station Gateway and Ecowitt WH32 Outdoor Temperature and Humidity Sensor which I use to measure the temperature and humity in my caravan
This has left me with the challenge of how to merge the 2 data sets. Luckily the Ecowitt has the ability to POST data to an HTML server and this required me to work out how to do that
Drawing on some inspiration from how I added the Rasberry PI CPU Temperature I decided to try to find a way to add the new data via a service.
I had some help from Jonas Frantz and the very helpful guide that he wrote here and incorprated all of the information into this solution
To make this work I am using the capability of the Ecowitt GW1000 Gateway to POST data to an HTML server, so if you haven't done so already you need to enable that on your Rasberry PI, instructions for that can be found here
