This may sound easy, but I can’t find a way to do it.
I have a DC irrigation valve the requires a +12 VDC pulse to turn it on and a -12 VDC pulse to turn it off. Once on or off, no voltage is needed to maintain that state. I’ve got a relay board setup to send the voltage and a python script that changes the state on two Raspberry Pi GPIO pins to control the valve.
Here’s what I want to do: Put a virtual button on Cayenne that when pressed changes the state of TWO I/O pins instead of just one. Is that possible?
