Hi Michael, that's exactly the problem. The format for time series you suggest requires to have a reading from every timestamp of every sensor. But that is not the case at all, unfortunately :-(
It might well be in my case, that one sensor reports 1000 readings during one day while the other one reports nothing. As we have to use epoc time (milliseconds), putting nil entries instead is not really a solution. Know what I mean?
