[arm-allstar] No electricity

Fri Oct 19 16:47:39 EDT 2018

Hello everyone,
Hello Doog,

OK I can see that there are people who are interested in this repeater site monitoring system

only to complete the project
I added a door contact
and also if possible to monitor on the 12 volts of the batteries?

I do not know if I'm too demanding
is it possible to do that with the Raspberry PI script?

to better visualize, I made a little hand-up
to better understand the monitoring system

for Electricity and door opening so it can be advise on the air

Maybe he's going to have other constructive comments from other people
but according to you Doug, is this project feasible ???

Thank you for your patience with us, but you are very understanding of the development of the world of amateur radio via All Star Link

Thank you and good evening

73’s
