## Requirement
I want to calculate the energy consumption of a sensor that on…ly provides me with power data at irregular intervals. This could be, for example, the output of a heat pump, a heat output meter or other time-discrete values. For this, we need to implement an integral function.
## Suggestion
Provide a Riemann sum implementation with different alignments (left, right, mid, trapezoidal). Center/mid alignment is the best compromise between accuracy and implementation complexity.
[Riemann Sums](https://www.statisticshowto.com/calculus-problem-solving/riemann-sums/)
## Implementation
I provided a Riemann sum mid implementation in this discussion:
[Arithmetic mean vs average linear/step interpolation](https://community.openhab.org/t/arithmetic-mean-vs-average-linear-step-interpolation/159892/15)
