liking this more and more.
would it be mains powered via transformer or is it battery powered ?
for me the boat is connected to the mains so would prefer that option

I need to put a shore power alarm on it. Either I can use a digital input to take a feed from a powered relay or I can use a software to do some maths using the internal voltage reference. There is a 1.1volt internal reference on the processor which can be read and compared with the overall power and I can generate an SMS alarm if it spots a variation. However I think I prefer the relay method as the maths for the internal voltage regulator are confusing to me.
