Tom,
Try these guys:
[Link: controlbyweb.com]I have been using them for years and have one in my own house.
They make several neat little monitor and control items.
Glad to see this, just took delivery on an X-310 for a project based solely on the fact Houselogix has a C4 driver for it. Intended use is to monitor a hydronic radiant heating system for a snowbird.
