I am building some code (VB .NET. not that it matters) to interface to C-Bus. One of the things I am doing is monitoring for events. I need to work out whether it is better to monitor Comfort events on C-Bus application 1 or on application 208 (security).
So far as I can see, zone status changes appear pretty much the same on both.
I must be missing something, because otherwise we would not have the bespoke application 1, there would only need to be the standard 208.
I have attached a screen shot showing a C-Bus Toolkit event log for Application 1 at the top and for Application 208 at the bottom.
In both cases, I have added Groups to the C-Bus Applications because, without those in place, the events are not shown at all. I suspect that is because C-Bus toolkit is designed only to show events in it\'s on-screen log, when they are for a known Group.
Both sets of messages seem to have almost identical information. Am I missing something?
Not sure how to get to the absolutely raw C-Bus messages (clues welcome). What I have done here is to monitor Port 20025 on the C-Gate Server which should show all changes. The bold headings have been inserted by me to try and add some clarity.
Waving an arm at the PIR in my study (zone 23). Source Unit 253 is the Comfort module.
I can see that it is reporting via Security zone sealed and unsealed which is a single group address on Application 208
This is fine for monitoring the activity of the zones, but there is no memory
For application 1, each group address corresponds to a zone, hence each group address has the status of the corresponding zone
In Ctouch, this allows the status of each zone to be displayed
If you are using your own software to monitor this, then you can also use the zone unsealed group address
I think I understand that now. I think what you are saying is that Application 1 is a Lighting-like application which has the concept of groups, whereas Application 208 is not and does not.
So, although the change messages are sent on both applications, only Application 1 keeps an internal representation of the values. So, I could use either application if I want to monitor the raw messages. However, if I want to be able to issue a query to C-Gate requesting the current status of a zone, that has to be Application 1.
That seems to be borne out by Toolkit - it lets me create groups within Application 208, but they always seem to be \"not known\" level.
Have I understood?
This does lead to a subsidiary question - look at the Kitchen PIR value on the screen shot. I need a clue on that one - I would perhaps have expected just on/off?
You have the correct understanding
Dont know about the kitchen PIR, the UCM only sends on/Off, perhaps there kis some other device giving this message?
