Well, after many years of trying to get it implemented....
I have a motor ordered for my roof!
I am hoping for installation within 3 weeks, by which stage my AAG cloud/rain/light sensor should have arrived
Rigging the motor up to the PC and writing a little bit of software to control it may take a little longer but I'll be happy once that's in my hands
Stepping up the automation a notch at long last
Fingers crossed
