Hello.
Namely, the electrician did his job, then the finishing touches and the rest fell on me in terms of connecting the sockets
Everything works except the double staircase in the hall where it exceeded my abilities :p

Between both double stair switches No. 1 and No. 2 there are 2x 3-core wires.
There is a power supply to the connector No. 1, the above-mentioned 2 wires, and a 4-wire cable to the lamp No. 1.
From lamp No. 1 to lamp No. 2 there is a 3-wire cable.
Who is so good and can solve the picture entitled connect the points correctly
?
I am asking for urgent and quick help - my mother-in-law is to move in any day and I have to take care of it...
Thanks in advance for any answers
