RE: CBus power usage

["Keith Doxey" <ukha@xxxxxxxxxxx>]

I don't know if Cbus do a module that could drive external relays, but if
they do you could add relays either between the dimmer and mcb or after the
mcb to physically disconnect the loads.

Of course you then have to spend more on hardware and program the system so
that whenever a dimmer is above 0% that you arrange for the associated
relay
to be operated as well.

Then you have to work out if the extra hardware cost justified the savings,
or whether just dimming slightly would be more econimical in the long
run!!!

BTW.. Wishing I HADNT bought a current cost because I cant get my
consumption down atm. Currently using around 30 kWh per day
