Ability to read the status for each entity at different time intervals.

[szczukot]

Describe your idea

For example, add an attribute to each entity (attr_scan_interval). This attribute would override SCAN_INTERVAL (from integration, if pooling was enabled) for the entity.
SCAN_INTERVAL would still be the default for all entities that do not set a different value.
Each entity can have the ability to change this value via the UI. Of course, this will still be locked to a minimum value (e.g., 5 seconds).

Why is this exciting?

It will reduce the load on the system/cpu/database in terms of the number of readings or written data.
It gives the user the ability to choose intervals - it does not force him to use what is set rigidly in the integration.
This can practically be used in any integration that uses pooling.

Potential use cases

I have some temperature sensors. Some of them have constant values, but others can report changes every few minutes.
I have a printer and I read its status. I'd like to know about errors almost immediately, but the toner status can update every few hours.
I have a 1wire data bus with multiple devices. With the default value, it can't keep up with the data transmission.

Anything else?

Pretty sure this is a duplicate already. Also, you can adjust this from the Ui already by making an automation with a time pattern trigger and a homeassistant.update_entity action.

It might be a duplicate, but I couldn't find it.
I even reported it yesterday:
