I'd still love to build my own thermostat, but this definitely addresses my bare minimum requirements for a thermostat and makes the Proliphix potentially viable for me.

Zub Fri, 29 Aug 2008 17:50:49 +0000 http://www.neufeld.newton.ks.us/electronics/?p=244#comment-22169 Here are a couple graphing resources for the Proliphix thermostats... They do not have a "true" SNMP access, but all parameters can be get/set using SNMP like http get requests... Their API is here: http://proliphix.com/files/PDP_API_R1_11.pdf Someone has already created a script to do rrd graphing: http://www.anders.com/cms/209/IP.Thermostat/Graph/Proliphix And for a small yearly fee, these people will graph the data for you... http://inthrma.com Geoff Here are a couple graphing resources for the Proliphix thermostats… They do not have a “true” SNMP access, but all parameters can be get/set using SNMP like http get requests…

I have been wondering about a decent method for measuring airflow and this was quite the efficient hack... when I implement my HVAC monitoring I may go for something just like this. But here's another question I was pondering - if you know fan RPM (taking as average value) and integrate over duct cross section can you calculate airflow in CFM? Oh and, you may be interested in 1-wire sensor bus for the HVAC monitoring/IP thermostat, it's an excellent solution and cheap to implement as well: http://www.digitemp.com/ Very nice.
