    Welcome.

    I am just starting an investment based on KNX and I have some questions on technical issues.
    I find it more convenient to lay the bus itself in 4 circuits radiating out from the RG in different directions. Each circuit will "catch" a maximum of a dozen sensors.
    The question is: how do I connect the bus wires in the RG to the actuators? I quickly came up with the idea of using WAGO rail-mounted connectors, which would also act as a bus like the distribution blocks in a traditional installation. Alternatively, you could use several actor connectors, which are designed for 3 wires, i.e. a connection between successive actors and one free field from the connector for the bus circuit, and since there will be a lot of actors, everything will fit.

    How is this typically solved?

    Thanks in advance.

    The topic has died, but maybe the author has come up with something. I need to make a "distribution block" to connect in parallel "a dozen" DS18b20 sensors, maybe 8 pcs, maybe 12, depends how it comes out. I am currently considering two versions:
    1. Wago 221-41 x2 + adapter - 3 such sets will serve me 8 sensors, poorly.
    2. rj 11 telephone splitters e.g. such https://sklep.satserwis.pl/rozgaleznik-telefoniczny-rj11-1-wtyk-5-gniazd.html
    Maybe someone has a better idea, more industrial?
