Yesterday, 3rd of April we had an almost tropical day here! so I decided to turn the boiler off, thereby ending the heating season...from now on, if the cold comes it is to be fought with blankets.
so, for the statistics:
6 Months of heating - from the 4th of October to the 3rd of March.
1640.81 m3 of gas for the winter, 712.71 m3 in 2008, 928.10 m3 in 2009, it was a pretty cold winter with plenty of ice! At about 60 cents per cubic meter, that is about 985 euro.
A total of 23464 minutes that the boiler was burning gas, or 391 hours, or 16 and a bit days, that in a total of 181 days, which makes it that the boiler was on for 9% of the time. Doesn't look like much does it...in the coldest month, January, that total was 14% of the time, in October it was a mere 2.5%, and in the current April 0.4%. Maybe I could derive an indicator to tell me when to switch it off based on the usage.
This total of minutes leads to 0.07 m3 per minute. Although this last number is not very reliable, since we also used some of that gas to take showers and cook...I should try to calculate the baseline cooking/showering gas consumption to be able to derive this number more accurately.
And all this heating was achieved with the server being up for 201 days, non-stop!
The doorbell rang a total of 99 times. A number of them (not many) it was me testing and making sure the battery is still working - should have made an indicator - an another (quite a few) number of them was a TV crew that came to shoot a program with my wife's research, and they had to film the presenter ringing the bell, which led to almost 20 rings, that added to the fact that they were trying to hear the bell ringing (which it didn't at the time!)
For some more statistics, there were yesterday, when I switched off the boiler, 46 daffodils flowering around the house! I'll try to keep track of how many blackbirds will be born this year on the garden!
For the coming times, I'll try to do some statistical analysis on all this data to derive occupancy rates, or in other words, to see statistically how often are we home on a certain weekday. Maybe I could adapt the heating with a neural network to heat according to the probability of us being home that day. That is the future!

If you have the data then it is a fairly trivial job for a neural network.

Indeed I guess it would be, but I have absolutely no knowledge of neural networks, apart from the name and a vague idea of what it can do, and of course, the wish to use one for a nice purpose. Is there a basic library which one can use to get to know it and program a NN?
It would be cool, and sound nice, to say the house is controlled by a neural network!
