For the people in NE USA - how much oil do you use?

[Auric]

Ceebee is that a circuit you designed??

You could probably use the additional inputs for other types of sensors too. Power, water level, etc.

Yup, I can add more inputs as needed when I move to another microcontroller. Right now I have some 5 available analog inputs but I'm not using them (and I don't really see a need to monitor other things TBH). But since the temperature sensors are 1-wire I can install as many as I feel like (subject to some 60ft max cable length).
Power - what to monitor??? It's very stable in my area. I could however monitor the actual usage level but it's one of those "meh" things.
Water level??? I have city water
What I want to do next is expand the functionality and incorporate a smart logic in a similar device to [......] - and that's a thing I plan to patent since it could be a money saver

no it can in fact exist, however we have no ability to measure it.

0 degrees Kelvin (-459.67F) is the temperature at which all atomic motion ceases... and the temperature is a measure of the average kinetic energy in a sample

Are you Absolutely sure there is a zero percent chance that all atomic motion ceases.

Yes - which is in line with the theory that says 0 K is impossible to reach

Hence why we are all in for a warm death (well warm by entropic standards anyway).

Nice! Well as far as the water level monitor, what I mean is using a water sensor in your basement so you know if you are having a flood. Not sure about where you are, but we have sump pumps that pump the water from the drainage out from the house.

CeeBee have you given any consideration to compare you Oil Usage to the daily average Heating Degree below what you like to heat your House for each month?

the only reason why I ask is because I been working on a excel spreadsheet that compairs my KWH usage to HDD per month. it wouldn't probly be that hard to convert it to Oil usage.

Yes...I am doing this and calculating the heating degree index for upstairs and downstairs by hour
However one can't directly convert kWh to oil because a heat pump's efficiency varies with the out-in temperature differential. Typical numbers that I found for one model used in Sweden show COP changing from ~2.3@ ~20F to 3@~40F - a 30% increase in efficiency, while for oil the efficiency is constant (use is proportional with the difference in temperature between in and out, disregarding additional heat input from the sun).
Furthermore, depending on humidity/temperature a heat pump may go in defrost mode more often, skewing the numbers.
