Hi,
wondering if I really need a rain sensor if I have a cloud sensor? After all, no clouds = no rain :-)
If that is the case what about this software at $30US that integrates with SGP?

Simply add an all sky cam, this software. Use it's trigger in SGP and then automate open and close the roof - parking to be worked out as well...
cheers
