I have a regulatory requirement, on my house build, for the building power to be shut off from the building by using an emergency stop button, located at my main entrance door. The button and wiring is in position and I can issue a command/signal in many different ways, through my KNX/Control4 control system, including using the Victron modbus register through the an Intesis gateway.
Question is; what is the actual process to make the Cerbo do what I want. I have tried using the writable MODBUS commands (limited) with no consequential actions. Can I issue a signal direct to the programmable input on the MP's?
