Is it possible to switch a socket automatically off, when another socket is switched on?
For example: I'm switching off(via the maintenance programm) my skimmer and air pumps in my outdoor pond during feeding time. This skimmer and pumps are controlled by 3 sockets (for example socket 1/2/3).
What I would like to do, is to install an automatic feeder on another socket (for example socket 4), which is working via a timer in profilux. When socket 4 is switched on, I would like to activate automatically my maintenance programm, so the sockets of 1 / 2 and 3 are switched off for several minutes.

Is this possible? And how to programm?
