Hello.
These are my first steps with Node Red and Home Assistant. I have some battery-powered devices where I would like to send a notification when the battery runs low.
This has been my idea so far:

I hope this works the way I want it to. How do I get the name of the node or the friendly name in the function node? So that the name of the device is instead of the +.
function node:
msg.payload = {"data":{"message": "Batterie von" "+" " ist schwach! ","title":"Wichtige Nachricht von HomeAssistant!","data":{"group":"Batterie"}}};
return msg;
Or does someone have a better idea to implement my project? I would be very grateful for help.
Thank you.
