Although I had loads of kit, I only actually had lighting and sound in multi room and outdoor setup. So all replaced with ZigBee puks in replacement to the C4 wireless ones, all plumbed into my Philips hue. Then got Sonos amps for muktiroom. Still had money left over after selling, and all works perfectly.
If the C4 hadn't failed 1week into living in I'd have kept it but it didn't inspire me with faith unfortunately, altho I here it's typically very reliable.

HI,
I've recently bought a new house from a previous owner and there was lots of C4 kit installed, but less than 2 weeks after moving in the HC800 decided to lose connection, which cut out all the lights etc, so had to get the dealer back to help. I'm new to all this C4 stuff so thinking about selling all of this instead. The kit i have is:
4 Zone amplifier (not sure of model)
2 x remotes (SR-260 i think)
1 x C4EA3
1 x C4-HC800-BL-1 (currently not connecting but power light on and link light is flashing)
1 x C4-WMB-B
2 x wallmounted touchpads
1 x freestanding touchpad
I'm not sure of the value of all this - i'm in the UK, any dealers or people interested let me know and give me an offer whilst i'm researching my options.
Cheers
 

The C4-TT7 is the current generation T3.

you are a new user, so buying Composer HE should still net you 1 free year of 4sight.  its based on being a new user, not new hardware.  As far as accessing a system left behind by another owner - I'd suggest contacting c4 support or an online remote dealer - which as the posts above implied - both are handled.
