Is it possible to trigger on a HA update available?

I’m wondering is it possible to trigger on new HA update available in NodeRED?

Check out the version integration. Create one sensor for installed version:

sensor:
  - platform: version
    name: HASS Installed

and one sensor for available version (with the config for your installation type):

sensor:
  - platform: version
    name: HASS Available
    source: docker
    beta: true

These are examples from my setup. Then in Node-Red do something whenever the available version sensor changes and if it is larger than the installed version, then send a message. I don’t use Node-Red so can’t help you with the details for the automation, but I assume it should be straightforward.

Thanks. This wil help
