What I want to do is to turn a pump off when three other appliances are off, and I want to turn the pump on again when anyone of the three appliances are on.
You will find it a little into thread, it is a modified plugin for the quad relay board, so that one can use the four relays separately, instead of two by two for blind controlling.
I modified the original plugin so credit is due to Drag0n for the main work.
