Hello all, I want to gather data from niagara framework in order to use third party software. Our ultimate purpose optimize HVAC performance. However when I try to run this code it gives me error grid:
/haystack/hisRead?filter=pressure&range=today
If I specify its id as mentioned in examples i can get his data why not using filters?

The hisRead op reads the history for one point at a time, as specified in the docs. So when you call hisRead you have to supply an id for one point.
For what you are trying to do, you would call read from the client side with your filter. Then iterate through the resulting records and call hisRead on them one at a time.
