Using entity_id from previous node in "Get template" node

Third party integrations Node-RED

I’m trying to use the entity_id of the previous node in the “Get template” node… sadly it seems I cannot figure it out myself;

I started with a poll-state node followed by a get-template node and want to do something like this:

{{state_attr("{{ENTITY_ID_FROM_PREVIOUS}}",'brightness')}}

obvious this is not gonna work

Anyone can send me in the right direction?

You can use current state node that receives as input msg.entity_id and to extract any attribute from the payload it provides

3

My problem is; how to get a payload and render it into the HA ‘get template’ node

I have a similar problem.

Its actually simple… like everything when you know :wink:
