To which event should I subscribe if I want to react to HA and addons updates in Node-Red

I want to send a notification to my phone when an update for HA or any of the add-ons exist.

Since HA creates a persistent notification when this happens, I suppose there is some event or state I can listen to but I can not find out which one.

Any help is appreciated.

Thanks!

There is sensors for that.
Go to the entity list in HA and type update in the filter and see them, then just react to them like other sensors.

I found those before but I would need to add them one by one each time I add an add-on. I am trying to get an “catch-all updates” node-red flow

You can set up a regex that catch all changes to sensors that have that update text in them.

thanks! I just now have to map the data but that worked
