I'm looking for a reasonably priced system to monitor temperatures in 2
locations and open/close 2 valves (or shut off pump) based on these readings.

Suggestions??

Conventional thermostat with output going through the coil circuilt of
a relay that when triggered, shuts off the pumps/valves.

Probably less than a hundred bucks.
