This may not be the right forum for this but I can't find any decent Home Automation forums other than this one.
I'm looking for the Honeywell W7006A gateway. It has a built-in web server and lets you change thermestat and security settings over the internet. Dealer need to be specially trained to install these and there isn't one in my area. I've read the install docs on Honeywell's web site and it is very simple for any computer literate person to install. Does anyone know where I may purchase one of these?
I believe I've seen that Honeywell product doesn't tie in too well with other automation systems. If this is important to you then you might try using AMX for net control of an HVAC system. I've setup control for a 15 zone house this way and it works very well using both AMX's HVAC system and Trane's BacNET.
Something to keep in mind is that Honeywell will not deal with a homeowner regarding warranty problems. If you have a problem, they will only talk to a dealer, and will not honor any warranty on such products not installed by a dealer.
