Is saver.save_state service call also allowed for more than one entity at once?

[Krzysztonek]

According to the documentation, this action is allowed:

service: saver.save_state
data:
  entity_id: cover.living_room

Question:

Is it also allowed for more than one entity at once?

In the Developer tools -> Actions panel I defined the following action, where data section includes not only a single entity but a list of couple ones:

service: saver.save_state
data:
  entity_id:
    - input_boolean.automatyka_gabinet
    - input_boolean.automatyka_garaz

Syntax is OK, no errors occur:

But does it really work for more than one entity in one service call?
How to restore them back using one service call?
If not, then how to save more than one entity at once?

I exclude the use of scene.create action with data snapshot, because it does NOT work as expected, since after each restart of HA this scene is being deleted and all the states from this snapshot are being lost.

Yes, it is possible

How to restore them back using one service call?

EDIT: Answer no longer valid - in v2.0.0 restoring entities is possible

You can't really do it. To restore the state you have to use templates that retrieve saved states.

Something like this:

action: "input_boolean.turn_{{ saver_entity('input_boolean.automatyka_gabinet') }}"
target:
  entity_id: input_boolean.automatyka_gabinet

As you can see, restoring state highly depends on saved entities

I have added an option to restore entities in v2.0.0

Unfortunately, after using this Saver integration for a few days I just realized that it does NOT meet all the requirements to be called SuperSaver, with all due respect to @PiotrMachowski's hard work 💟

Saver only works perfectly until the HA restarts. After each HA restart, all already saved entity values ​​are lost. Therefore, I would need a different integration for this purpose.
Seems the Variables Integration developed by @snarky-snark works fine and more reliably, preserving all values ​​even after the HA restart.

[PiotrMachowski]

Data saved in saver should survive the restart. There might be a problem with your setup, because it works perfectly fine on both of my HA instances.

[Krzysztonek]

Yes, you're definitely right, @PiotrMachowski, apologize!

Mea Culpa!

Saver domain was simply explicitly excluded from the recorder. This is why after HA restart I wasn't able to get my saved entity values back..
Now it works exactly as expected. Thanks a lot for your contribution. 🍺
