Update helper values from nodered

Third party integrations Node-RED
1

Hi

I’d like to update a lot of measurements in HA from node-red using the node-red-contrib-home-assistant-websocket API node using websocket. To keep all config in one place for some items I just use node-red as a data collector, but I am looking for an easy way to get these data to HA, which is some kind of front-end for this node-red code.

Simply as a proof of concept, I created two helpers, with entity ID’s: input_number.gtst test1 and input_number.gtst test2

Now I want to set the values of these items using a function node containning something like:

msg = {
    payload: {
        domain: 'input_number',
        service: 'set_value',
        entity_id: 'input_number.gtst_test2',
        data: {
            type: 'change',
            value: 123.45,
        },
    },
};
return msg;

But this doesn’t work. Can anyone provide my a working example?

I know that I can hard code the entities, but that’s not the way I want to go. Just looking to dynamically assemble messages with entity ID’s and values, which I can fire from a function node one after the other. Of cause, 1 massive update of the HA values would be even more useful. But I can’t see how that’s possible

Thx

This is not a persistent entity in HA.
It will first be available when Node Red updates it.

Hi Wally

Thx, your info was the key.

As an example below a test of how I developed my configuration. The first function node is an example of data being collected in a dictionary. The second function node then contains on top some config to connect the data in the dictionary to the according HA tags and then a loop fires change value messages one after the other to HA.

Some other question:
If I want to provide eg room data from NR to HA, then I need to create a lot of helpers in HA:

  • room1_temp
  • room1_humidity
  • room1_lightintensity
  • room2_temp
  • room2_humidity
  • room2_lightintensity
  • roomX_…

Is there a way to create a custom sensor “roomsensor”

  • temp
  • humidity
  • lightintensity
    that can be instantiated as room1sensor, room2sensor, roomXsensor …
