In your first request for help you said, "How do I average the
measurements by every 30 minutes?" With 25000 readings over three
days, it looks as if you are getting readings just about every
second.
Okay, why don't you use the first reading as your initial weight,
w0. Then subtract each succeeding reading from that to obtain the
amount of feed dispensed. Now plot that value every 30 minutes.
If you are interested in the variation of feed dispensed over a
half hour interval, that can be easily obtained by accummulating
those half-hour readings.

I do not want smoothing as the data should have jumps (it is weight left in
feeding bunker). I was thinking of maybe using a histogram-like function and
then averaging that. Not sure if this is possible.
