Some Further Thoughts on TED

So, I've learned a bit more about TED and I owe their designers an apology. They do provide easy access to both MTU's data. I just had to go down the drop down box a bit further to find the separate export options. It just turns out that for me, the one MTU has an average measurement of 4 kWh/hr and the other one is 0.4 kWh/hr, making the split between the two not that interesting from me.

If we pull out the other activities going on, we can isolate the heat pump as a 9 kWh/hr load (wow!). This is the single largest and most notable load in my house and one that needs to be addressed next year.

Also, I learned a bit more about TED in that the Footprints software actually exposes its current information using http. If you go to http://localhost:9090/DashboardData on a browser on the computer that is running, you'll get the below XML. If you have a static IP address on this computer (reasonably easy to set up on a modern router/wireless access point using the computer's MAC address), you can then call the information from any computer on your network.

Unfortunately, despite all of the wondrous information (including separate real-time readings from the two different MTUs), they left out the current time. Huh? They included lots of random daily accumulations of data, but not the current timestamp. Odd choice, not quite sure why they would see fit to include the month and year, but not the full timestamp.

This seems well suited to a WAMP setup to capture the data in a much more flexible fashion (though one that's much more likely to fail at some point).
