Rest api for json object

Hi

I am trying to include a json data source in HA with the rest api. I am partially successful with that, but still a couple of questions remain. The json data source looks like this:

{ "version": "0.8.0", "generator": "vzlogger", "data": [ { "uuid": "ca24687e-0481-4770-94d5-657d7db65f66", "last": 1574848158398, "interval": -1, "protocol": "sml", "tuples": [ [ 1574848158398, 366.60000000000002 ] ] }, { "uuid": "3beb68cf-a2aa-4ff5-bd66-58cb0d3bd58a", "last": 1574848158398, "interval": -1, "protocol": "sml", "tuples": [ [ 1574848158398, 3656154.8000000003 ] ] }, { "uuid": "2e3485a7-f210-4796-9ddb-f8769892c227", "last": 0, "interval": -1, "protocol": "sml" }, { "uuid": "5e8a172a-c778-45c1-8b5d-597629cd4953", "last": 0, "interval": -1, "protocol": "sml" } ] }

I am interested in the uuids and the second value of the tuples. Thus I wrote in my sensor.yaml the following code for each of the uuids:

  - platform: rest
    resource: http://192.168.205.201:8080/
    value_template: > 
      {% for i in value_json.data %}
         {% if i.uuid == "3beb68cf-a2aa-4ff5-bd66-58cb0d3bd58a" %}
           {{ i.tuples[0][1] }}
         {% endif %}
      {% endfor %}

    method: GET
    name: "Zählerstand Haushaltsstrom"
    unit_of_measurement: "Wh"

It (kind of) works, but I have two questions:

• Is the for loop really necessary or is there a more elegant (and faster) way to solve the problem?
• How do I divide by 1000 to get kWh (instead of Wh) and round to one or two decimal places?

Thx

Thorsten
