Let Alexa welcome you home

Using Home Assistant and Node-RED, I created an automation that not only greets me when I come home but also tells me who is home and who is away (and how long).

Welcome back, Celine. Dylan and Mom are also at home. Dad left two hours ago.


The flow

Our imaginary family consists of four persons: Alice and Bob (parents), Celine and Dylan (children). Here is my flow:

Node Red flow (source code below)


The nodes annotated with red letters will require tweaking for your requirements.

C: Filter family

The flow will only greet your family (or any other selected group of people). You need to change the array for your family or completely remove the node if you don’t want to filter at all.

D: Front door opened

Change the binary sensor to your door sensor (or any other sensor you want to trigger the greeting by)

G: Create message

Here you can change all the texts that are used for the greeting. It should be easy to localize it for your language, and English and German strings are available already.

A really cool feature I think is the relations map. Children normally don’t call their parents by name but by “Mom”, “Dad”, and so on. So with the relation map, you can override the friendly name for the kids.

let relations = {
  "person.celine": {
    "person.alice": "Mom",
    "person.bob": "Dad",
  "person.dylan": {
    "person.alice": "Mom",
    "person.bob": "Dad",

H: Alexa

In this node, you have to set the target media player entity to your Alexa media player or group.

Extending it further

In the future, I’d like to know if the dishwasher, washing machine or tumble dryer finished while nobody was home. If you have access to the calendars or location of your family in Home Assistant, it could also be nice to tell not only who is not home, but where. If you have more ideas or wrote something cool, please write it in the comments below and I may add it to the post.
