I am installing a hot water radiant floor system. Just for fun, I want to monitor various water and air temperatures (hot water supply, hot water return in each circuit, room temperature, etc.). I was surprised when an internet search turned up few options for doing that for a reasonable price.

I did find this system: http://www.welserver.com/

It looks great. Seems like a good, common sense approach to me.

Anybody out there have experience with this sort of thing? Any recommendations?
