Sorry guys- been in the midst of launching development on a whole new round of great AcuRite products
Yes, the 5n1 measures in .01 increments for rainfall- which I believe has worked well for folks.
If you have a PC Connect product (01515, 01035), and you want even more connections and publishing options- certainly check out weather-display. It's LOADED with options for the enthusiast.
And that's a great point about expanding the specifications documentation for the 5n1 sensor suite- we will work on getting that onto the website.
Thanks for the feedback everybody, I will try to get on here more often to answer questions and address concerns.
