Tags and NodeRed [Help ..]

Third party integrations Node-RED

Boredcat (Jacko Ammerlaan) January 2, 2021, 12:01pm 1

Hi,

I need some help with use TAGS in node red. I have a esphome build NFC reader, which works as very well. In the native automations I can use the tags. But I want the tags in node red (since I do all the automations in node red).

What I want is that the tags are passed to switch (which contains all the NFC tags that I needed) to I can start the action for that tag.
But how to I get the tags since its not an entity … its part of a trigger event … I already found out that the tags are in a message object … and I need a function to get the tags , but no idea how to create the function …

I cannot help specifically with this, since I am not using Tags.
However, maybe the generic tip will help you out:

To find out the even trigger you need:

Create a new Event Trigger node and listen to ALL EVENTS. Connect this to a debug node and set it to COMPLETE MSG OBJECT
Then scan a NFC Tag and look at the debug node output.

There you should see exactly the event you need to listen too. Then just filter for this, and use the message further as you see fit.

Can you copy the entire msg.payload here? I don’t know the structure of the message being sent. But, usually, it is rather easy to extract the “correct” information from a payload…

OK. So, put this output into a json node and then the tag_id is in msg.payload.event.tag_id.
From there, through (eg) switch node you can decide what you want to do with it.

This is the way I do it:

Thnx. That was the info that I needed.

Thnx for all your help.

I just noticed NodeRed now has the Home Assistant Tag:

So you don’t need to look for the triggered event anymore.
