Scenes - only working intermittently

I have a number of simple scenes, principally to turn all the lights off. When I invoke such a scene, all the lights turn off around half of the time (i.e. success around half the time). The other half, however, one or two stay turned on (whilst the rest switch off). There is no obvious pattern: different lights stay on at different times. Any thoughts?

 

How many groups in the scene?

 

Maximum of 8.

 

That blows my theory of too many groups.

Try using Toolkits "Application Log" to see if the messages are being sent.
Check network: voltage, burdens, clocks etc,
Try the C-Bus Diagnostic Utility.

 

Shepard,

Thanks for the reply.

Have already done so - looks ok to me.

Have already done so - ditto (with the caveat that, as far as I can see, scenes can't be invoked within the utility).

I'm not sure what I should be looking for here, nor where. The wireless gateway shows: voltage - 32.3V; burdens - not enabled (global tab) and not active (status tab); clock - enabled (global tab) but not active (status tab). I have just enabled the burdens and it now says enabled (global tab) and active (status tab).

How are software burdens relevant and should I enable them given that my installer clearly didn't?

 

Should only have one burden active on wired network. He may have a hardware burden (RJ45 plug with pink heatshrink) pluged in somewhere.
I haven't played with wireless sorry.
Maybe explain your network layout more, for others to diagnose.

 

Again, thanks for the replies.

My wireless units are around 5m apart: one per small room and two per large room.

When I spoke to my original installer, he suggested that it might help if each scene (3 in total) was stored in each unit, rather than on just one unit as he had done. So, I did this: it helped reduce the problem but did not eliminate it.
