All If you are a Comfort user and have their CBUS interface module, there is a poll for enhancement to allow for long messages - so they can support sending information such as Text to DLTs (and perhaps more once this is supported) You can find the poll here- [URL]http://comfortforums.com/forum11/1454.html[/URL] Hopefully, the protocol information will be published in the future to allow the Comfort module to send group allocations to a CBUS switch. Benefits are when the Alarm is in Away mode, we can essentially set all switches groups to <null> - if there is an intruder, they won't be able to control anything and we can control lighting (is flashing). Clipsal - at least tell Cytech how to do it, even if we aren't supposed to know ! thnx :-)
