Using 'get entities' to listen to multiple event states?

Hey there,

I want to use node red in my home assistant to listen for new update relases and notify me on my phone.
Right now I’m using an event state regex to listen to all entity ids starting with “update.*”.
Regex:

^update.*

Is there any possibility to make node red listen to all entites using the “get entities” node and not using regex or a list in event state?
Please see the example below.

What type of entities require individual updates? Are you looking for the HA updates? Have you added the version sensor?

You also have the group option that lets you create a single entity from multiple.
