Ok. Sao what is the issue. you need to connect some relay board to your node-red server. Enter you longitude and latitude in the function and if the result of the caclulation is less than some number send a message [payload to the relay to turn off the amp. later turn it back on.

I am using the W8BE node red lightning flow , which I would like to use to switch a relay that disconnects the amplifier.
