What happened to Spring

I went from running the heat to running the air conditioning in less than a week. What happened to Spring?

PS - this is a graph created by a small program that reads a database that is populated with indoor and outdoor temps as well as HVAC status via CQC. I'm running a TR-40 thermostat and pull outdoor information from the Weather Channel (I don't have a outdoor thermometer).
 
Nice graph! Curious how you make it....and if the idea could be uhmmm..."borrowed"...

Good stuff!
 
Here's my HAI outside temperature sensor graph from polling temps. Today it cooled off a bit here (49F).

Ok, pete it's not nice to tease us!! Someone please post teh program they are using to generate the graphs on the fly? And is your data being stored in a database or is it a flat file?
 
I do use a database to record changes in my system. Right now I am recording inside and outside temps, the HVAC run status (ie heat running, cooling running, nothing running), incoming phone calls, alarm status changes, etc.

For the graph, I use a small program that a CQCer created called Graphmatic. It uses an XML file to determine which database fields to read and how to present them on the graph. It must be executed manually (ie it doesn't keep real time graphs going on the fly). There are two basic ways to make that work - either run a scheduled event every couple of minutes which will create a new graph, or only run the program when you load the interface that contains the graphs. This is the approach I use currently, but might switch to the scheduled task method.

It's really the first time I've seen a graph of mine that showed both heating and cooling HVAC usage in the same graph which is why it peaked my interest.

PS - I would be happy to share my XML file with people if they might be interested. I "borrowed" it from another CQC user and tweaked it a little myself. So it is only fair that I pass it on....
 
Todd,

Its a DB running with HS/MCS Temperature.

Starting to play with some independant graphing using XaP values and creating dynamic graphs on Kodak Photoframe that Michael has been writing. This will allow an independant on the fly generated JPG/RSS temperature graph.

Its written about here:

XaP graphing
 
Pete if you could share the polling part to fill the DB that would be cool. Graphing real time off a DB is no problem I use f-source flash charts all the time at work jsut set a browser to autorefresh and it is real time. Trouble I have is getting the data off the HAI. I wish I could also do it with my HP Home server so I don't have to leave another pc running.

Funny I bought the HAI to help save money, electric, now I run the hai, 2 sub pannels, 4 power supplies to power everything and HP home energy eater, sorry I mean hp home server.

But I do like that you can see in the chart above when the heat and AC kick on. and how much they run.

I currently use an HAI Homeseer plugin via a serial connection to get the HAI data over to HS. From here it become a variable that goes into a DB.

Ideally one said independant application which would also input/output data via XAP would be a great addition to HAI's application suites. IE: Today a very old application called "speedfan" has an option to output xap which I utilize.

Currently its a plugin for Homeseer called MCSTemperatures and specifically its a trending page that you configure to query a database and build your chart. I have been using it for probably 10 years or so. What I like is that you can modify numerous variables and methods of presentation of your graphs with it on the fly. I use the lightning graphs sometimes while I am golfing using my cell phone. There now exists independant Xap applications written by Michael that will do same said historical and real time charting and queries without running HS that you can run on any PC. I am just starting to play with these relative to using the Kodak wireless photoframe. So if you just poll the HAI variables and plug them into an XaP application, record the variables in a DB you can then real time or historically chart them.
