Controlling roller shutters centrally and locally without radio systems - how to do it?

The discussion addresses how to centrally and locally control five roller shutters using wired switches without relying on radio systems. The original wiring plan involved 4-core cables from a central switch to each shutter, but current regulations and practical control schemes typically require 5-core cables, including a protective earth (PE) conductor. The fifth conductor is essential for safety and compliance. For local and central control integration, "bell" type momentary switches are recommended, as they send a pulse to roller shutter controllers that handle timing and motor activation, eliminating the need to hold the button continuously. Roller shutter controllers such as RCS models or modules from Fibaro (which support wireless control with manual switch inputs) can manage this functionality. INEL offers affordable radio controllers with local key button inputs, but purely cable-based control demands appropriate wiring and compatible controllers. The central control switch must be wired correctly with the local switches and the roller shutter motors, ensuring proper power supply and signal distribution. The discussion emphasizes the importance of correct wiring (5-core cables) and suitable controller electronics to achieve combined local and central control without radio systems.
