Alexa Local Operating a group from Hass.io

Third party integrations
1

I’ve got Node-red working with the Alexa “amazon-echo-hub” and can turn a single light on an off with ease.

In my groups.yaml I have:

  All Lamps:
    name:   All Lamps
    entities:
        #- light.sf_10
        - switch.sf_04
        - switch.sf_03
        - switch.sf_07
       - switch.sf_09

This gives me a nice group that switches all lamps on/off in lovelace just fine.

I’m having trouble with setting up the “api-call-service” node. What should i be inserting in the DATA section for the group? When it’s a single lamp call: {“entity_id”: “light.sf_10”}.

{"entity_id": "group.all_lamps"}

does not work

Domain: group
Service: turn_on
Entity_id: group.all_lamps

Just use the call_service node and not the API node.

Sorry where would i find the call_service node?

That’s the one. :slight_smile: Plug in what I posted above and it should work fine. If you want to adjust brightness or transition, those would go in the Data field (as JSON).

:slight_smile: Thats the one i was trying…

Each time i call it i get a api error…

More investigation tomorrow. Thanks for the help to date.

After some digging the simple group switching with Alexa can be achieved setting:

domain: homeassistant
Service: Toggle
