Hello All I hope someone can help. I am a complete novice with cbus. I just looking to find out if my unit needs to be reprogrammed in some way. So basically. I have a cbus unit 4 channel which controls some outside functions at a gate, such as pillar lights, bollard lights etc. So I can toggle these on and off at the cbus unit, I.e. Override or at a face plate located in the house. Current there is a gsm gate controller linked into the gate cbus unit, via the relay terminals under neath the cbus unit and in turn these relay terminals are connected to relay outs on the gsm controller. I am assuming then when a call is made to the gsm controller and a keypad number on the phone is entered the relay is activated. Current selecting number 1 is fine. The gate simply opens, but selecting any other number nothing happens. So the question is, is there a way to find out if the cbus unit needs to relearn the input command from the relays? If so is learning mode the way to do this. Many thanks in advance
