I’ll look into automation a bit more and come back to you if I want to head down that path.

That hydreon rain sensor looks better than the simple capacitance one I'm using and it would be easy to incorporate that as an input to the Arduino if you wanted to (and I might get one to try).

I had never built a windows application before embarking on that project (and had no idea what an arduino did either) but the reality is coding is logical and not rocket science so if you are prepared to learn something new and spend some time with google it is do-able and satisfying. Disclaimer - I'm a chemical engineer...not an IT professional/programmer so what I'm doing is self taught.

I could have purchased a commercial unit but for me the fun is in the creation of my own solution. I'm lucky I have time to spare playing with this stuff and understand others just want something off the shelf that works out of the box. That's the beauty of this hobby - there's something in it for everyone.
