Does anyone have a solution to this problem?

My solar driven water pump is about 1200 feet line-of-sight from
the tank it pumps into.

There is no wire going between the two and it would be no fun to
place such a wire.

The pump controller has a connection such that a short across it
turns off the pump.

Thanks for any help!

Radio or laser link?. A transmitter intended for radio
controlled models would work if fitted with a directional aerial. If you
have line of sight then an optical link using a modulated laser pointer
is theoretically possible but 400m is a long shot.

Can laser pointers be amped up a tad? Ilike the laser route because
it seems easier but still more fun than radio.
