RE: xAP enabling Honeywell heating controller

["Paul Gale" <groups@xxxxxxxxxxxxxxxx>]

Thanks Kevin.

I think I want a solution where I can use the (dependable) supplied
control=
ler for day to day functioning etc - and then be able to program that
throu=
gh Main Lobby (and xAP I guess). Plus be able to display setpoints and
temp=
in ML.

I agree about the reliability aspects - I'm currently struggling with a
cou=
ple of areas in my HA system that need constant re-setting and
maintenance.=
Oddly enough, HomeVision is currently one of these mis-behaving systems an=
d occasionally locks up! We think it's down to interference but I've got
li=
mited room ATM to properly troubleshoot, so am really waiting for the new,
=
bigger Node0 to iron out the problems (hopefully). Heating has to work
reli=
ably though, so a system that has xAP or any other PC link as a REQUIRED
li=
nk in the system is out. Data reporting and the ability to set everything
w=
ithin ML is a different matter though as I wouldn't see that as
'dangerous'=
:)

Paul.
