@ricvice You have reached the 'interesting' point now. You have the hardware, you sort of know what you want, but need to learn how to do it. We have all been there! So start with a clear idea of the system. Where are the displays going to be etc. Then try to make it work. Start off with simple sketches that do things like measure analog voltage (see battery powered sketch) This will be useful for the wind speed. Then look at the 'build' section at the top of this page for temp sensor. Again, try it and see how it goes. Gradually things will become clearer and you will be able to try and combine sketches into one that does it all for you. Small steps go a long way with this. You will need to make a gateway and choose a controller to use mysensors and display data, but you can easily see graphs etc so it could be worth it for you. A simple raspberry pi 3 and a pro mini would do for controller and gateway. If you get stuck or can't figure something out then post on here with your code and someone will help you. IF you don't want to go the mysensors route then the arduino forum would be a better place to ask as this is really only for mysensors related discussions.
