Manually triggered automation advice

I don’t use node red or know much about it, but you may find this helpful:

How to trigger a flow in node-red from HA lovelace ui?

You can use a button in lovelace to fire an event when pressed and listen for that in NR. If you have the NR custom integration installed you can call the nodered.trigger service call from a button in lovelace.

If you stay native HA, you would create a script and have the button call the script (either directly with script.my_script_name or use the script.turn_on service)
