Hello,
I am trying to get the number of days in the time range to multiply and add to a value.
Basically, the graph on the left is my energy in kWh but the one on the right should be it translated to $$, and it is based on energy used plus a day rate tariff. Is it possible to get a select that return the number of days in the time range. @emiltullstedt@torkel
Hello all. Can anyone point me in the right direction for rolling up counts/sums into 24-hour periods?
e.g.
I have an IoT device that started collecting data at 1pm 9/1/2021 to 12:59pm on 9/7/2021.
I want to roll up and $sum the events not by calendar days, but by 24-hour periods starting at 1 pm on 9/3/2023
Ending up with something like [{ day: ‘1’, value: 240 }, { day: ‘2’, value: 260 } , { day: ‘3’, value: 210 } ]
I know how to rollup data by the calendar day with $group, but haven’t approached it before from a calendar agnostic time interval with a given start date.
