RE: CBUS assistance

[Christopher Purves <CHRIS_PURVES@xxxxxxx>]

I should say everything I do is scene based. I observed the 'weird'
behaivour after a rcd tripped. It may as you have suggested be the button
indicators that were wrong.

scenes to get this to work. I am only used to DLT's on which this is quite
possible as you describe but you would not define a new group to do it. I
have observed that you can get some weird behavour on cbus - it seems to
have memory. If a switch thinks something is off but you turned it on on
the dimmer itself for example a single push of the switch would not turn it
off. You would need to press it twice to get the desired effect. You can
get stuff like this after power cuts until the state all gets itself sorted
out.
