Hi, I have taken over a system controlled by clipsal. I have successfully managed to integrate the lighting and blinds via a serial interface using the protocol documents. I am having some problems getting some temperature values back from a PC_GIM. I can see in the protocol document for the 'measurement application' that the data messages are sent from a device when the value changes, a specified time interval has elapsed or after the device has received a request for an update (via a control trigger). As I can't see any data being received via the serial interface I assume that the data messages are not sent to the interface when the value changes or the time is elapsed? I have looked into control triggers and I'm completely lost as to what command to use. I have attached some screen shots from c-bus toolkit for the PC_GIM settings to see if they help understand my problem. Images 1-3 are from one PC_GIM and 4-5 are from another. Any help would be greatly appreciated as I'm very much stuck and not sure who to turn to for help. Thanks, Simon
