I have the following flow which turns on and off pumps of a hot tub to protect it from freezing.
The circulation pump should only be turned off if it wasn't turned on from a different flow which triggers the pump for filtering.
Does anyone have an idea how I could do that?
When you trigger your filtration pump, add a
change node to save the state of the pump in a global variable. With this way you can check if it isn't working and turn off your circulation pump. Between your
Turn Off node and
Pump Circulation add a
switch node which checks if your global variable is off, which transmits the message to turn off the circ pump.
