A tabular visualization of this data (useful, for example, prior to calculating the sum of all modes) will present the data as a list of time series, with all dimensions. Of course i can go into openhab and create a virtual item + rule, which would do the calculation and write its value into the DB, but this is not the right way i think, as it is one more measurement running permanently. The print screen . 1 Answer.
