Calculating and displaying daily min max temperatures

Hi, I’ve been searching the forums both current and archive and can’t find a good answer to this.
I’d like to have feeds that record the min and max values over a given 24h period (not 12am-12am necessarily) so they can be displayed on a dashboard. Like the max and min you get from the weather forcast.

There is some info on how to modify some php processing functions, and that seems like way too far down in the weeds. The other alternative I can think of is NodeRED processing. I think that’s the approach I’m going to try, but I was wondering if I was missing something obvious?


OK, so I just found the Max daily value process when adding feeds… That’s what I was looking for.
Is it midnight to midnight? Can this be easily changed to match the weather forcast peoples way of doing this?
