How to check if item avg value for the last week has change

[batchen_regev]

Im using zabbix 5 and i dont understand how to create an avg trigger that will tell me if X item avg has changed from the last week.

X item is returning a number, i want to know if there was a change from a week avarage comparing to the next week or day.

For exsample :
if last week avg was the number 7 and this week avg (was 8 or greater ) has gotten bigger + 1 even - i want a trigger
if last week avg was the number 7 and 1 day avg (was 8 or greater) has exceeded this week avg +1 bigger - i want a trigger

I have this now :

{Template Ansible-Features:c.conn[{#CCC}].avg(7d)}=0

i should make it like

{Template Ansible-Features:c.conn[{#CCC}].avg(7d)} < {Template Ansible-Features:c.conn[{#CCC}].avg(1h)}

or

{Template Ansible-Features:c.conn[{#CCC}].avg(14d)} < {Template Ansible-Features:c.conn[{#CCC}].avg(7d)}

Thanks for the help.
