Helping a friend with a hot water circulation pump. They had a system that circulated water based on a timer but even that wasted a lot of energy keeping the pipes hot when not in use. Converting to a system with wireless push buttons in three locations that would trigger the pump to run for about a minute to get hot water to the sinks but only when a button is pressed. If I was doing it for myself I might use an arduino and a relay in a box but want something that can be adjusted for time without programming. Any suggestions for hardware? Need a relay that can switch 120VAC (current is a few amps) and a way to trigger it from wireless push buttons.
It looks like Functional Devices Relay in a Box RIBD01BDC can handle the delay so I would just need 3 wireless push buttons and receiver to feed the dry contact input.
