Hi Robin
Thanks for the reply.
I have a changeover which will automatically failover as required but I need to start the generator in the event of a power failure. My home is fully automated (intelligent) and to detect power loss is no problem.
I have done some searching and have come across a few diagrams posted by various people but looks very suspect. I'm not too familiar with Arduino yet but very very familiar with home automation and I am a qualified electrician.
I would like to attempt this using Arduino to compliment what I already have.
Regards
Leighton
