Notification from HA and Node-red to mobile app when person state changes

Hello

I am trying to figure out how to send a message to my phone app when kids leave home and enters home. I have a person state home/away on each person entities, and I can manage to get one entity and one state, in ex. kid 1 is home, but how can I select multiple entities and multiple states, and get a message when one of the entities changes to a new state?

@Linax Is this something you could help me with?

Might be able to help but can not promise. Could you share the flow you have now and what you get in debug when it is set to complete msg object when someone leaves and comes home. Would also be helpfull to see all the person names under http://ip:port/developer-tools/state
