Thanks all for your help and thoughts!
Regarding the Wunderground IP, that’s perfect.
Regarding the rain sensor, I’ll get it going. Between your suggestions and that of salbahra, I can make it happen. It was just a difference I noticed between the Python version and your C version.
About the zones, this is surprising given that there is an expansion module. When you note that there’s not currently support for more than 7 zones, do you mean with your c version, or with the Python version as well? How about the Arduino version of OpenSprinkler?
In any case, if it can be programmed, I’m certainly willing to help test. I’m working on getting this all set up in the garage. It’s really pretty cool. Let me know how I can help.
