Re: HA without fallback-CBUS

[David Gumbrell <david.gumbrell@xxxxxxxxx>]

Hi Chris,

Trying to avoid hijacking the thread too much ...

I've started a sort of diary of my experiences on my
blog<http://www.gumbrell.com/archives/home_automation/>.
It's also linked from a
posting<http://www.automatedhome.co.uk/modules.php?name=Forums&file=viewtopic&t=746>in
the "General Discussion" Forums on automatedhome. I've not
updated it
in
the last week, since I was moving hosting off the unmentionable one ...

I'm sending a more detailed reply off-list

Cheers,

Dave
