Dashboard does not update when database changes

I am reading data that comes from a postgresql database,
which updates some plots, tables, maps, etc … The flow
is not continuous but random based on “events”.

I always have to “refresh” the browser to see the changes
in the browser.
I am doing something wrong ?

Browser: firefox / Chrome
Grafana version: grafana-7.3.1-1
OS: CentOS Linux release 7.9.2009 (x86_64)

In grafana.ini

min_refresh_interval = 1s

in Grafana database config (postgresql):

Min time interval : 1s

in each query to the postgresql database, I used
the “Min interval” option set to 1s.

Thanks a lot for any help . …

the postgresql database runs locally …
