Oil consumption energy IQ
Anyone has good workaround on hot to calculate heating costs with oil heating? The best I came up is to say 1 litre oil gives 10kwh and cost of 1kwh is cost of the 1 litre divided by 10. Not sure will this correctly calculate cost yet to see. Any other ideas?

I would be interested if you have managed to work this out for yourself. My solution so far is as follows… I have a device on my oil tank that tells me the volume early each day - it sends me an email. I record this as if it was a reading on a meter. Yes when I buy more oil I have to adjust that meter reading my the volume i bought. By this means get a figure for how many litres of oil were used during the month. (I get through a fair amount of oil as this is a small office building so the 25 liter rounding my gauge does is not too significant except in the summer months, which of course are less critical in any case. I have ten rooms (have grouped several together) with 25 heating devices - so the maximum that tado can cope with). Under Energy IQ have selected Meter Readings, and units are cubic meters. (Sorry office is in the UK, my computer is in the US, hence the spellings!) Under energy tariff every time I place an order for oil I enter the price, but move the decimal point a few places! So recently i filled up for 60.62p per liter. I have entered 6.062£/cubic meter. So now under the Energy IQ tile under 'home', it gives me a number £s cost (If I look at last January for example, the month of highest usage this year, so makes the +- 25 liter issue fairly irrelevant, it is showing £431.81 of oil used, and a volume of 62.53 cubic meters. Is that about right? Well my gauge measured a drop in volume of roughly 850 cubic liters BUT outside the Tado system I also run an oil fired space heater in a warehouse, from the same tank, and of course Tado is not 'aware' of this, so accepting that the decimal point is in the wrong place, and adjusting for that, 625 cubic liters versus 850 probably reflect the volume used by the space heater, say 225 litres., about what I would expect. the £431.81 would have bought me just 709 litres of oil so somewhere between the taco number and my tank gauge number. Not a perfect science, and yes I moved the decimal place to work within the limit Tado sets for costs per unit, this is as accurate as one can get. Over time I will be able to calculate a variance and apply that to the numbers so get a reading I have greater confidence in.
