Because I also did not know what else I might need later in the garden, I misused "Rechtsanwältin Bird JMB-H Ventilbox" as distribution boxes around the house and connected them to each other with 1-2 Kabuflex empty conduits. Two KG-110 empty conduits go directly into the utility room under the control cabinet. This way, I can pull cables flexibly and as needed from the utility room to wherever I want. Only the final installation still needs to be done, but without having to dig up the whole garden.
