with big timer I have a time program, this has to switch a lamp on and off, but when I turn on the ‘vacation’ switch the lamp has to stay off until the switch is turned off again. Then the lamp has to follow the current time again as the time program is set.
How do I make a flow for this in node red
Use your vacation switch to set a vacation variable and check the value of the variable between your Timer node and your lamp node.
I’d also set a flow that when you turn on your vacation switch it turns off your lamp. I’d also suggest setting a time variable that says if the lamp should be on or off, and when you turn off your vacation switch check that variable and turn on your lamp if it’s in the ‘on’ time window.
