I’ll just throw this out here and you decide if it’s worth your while.

If you don’t mind having the state of sensor.bryan_cgm in a terse, space-delimited format like this:

164 4 Flat 6

instead of a descriptive format like this:

sgv:164, trend:4, direction:Flat, time:6

then you can use the following code which streamlines the Template Sensors.

  - platform: rest
    name: bryan_cgm
    resource: !secret nightscout_url
    value_template: >
      {{value_json[0].sgv}} {{value_json[0].trend}} {{value_json[0].direction}} {{ ( (as_timestamp(now()) - as_timestamp(value_json[0].dateString) ) / 60) | round(0) }}

  - platform: template
    sensors:
      bryan_cgm_sgv:
        value_template: >
          {{ states('sensor.bryan_cgm').split()[0] }}
        unit_of_measurement: "mg/dl"
      bryan_cgm_trend:
        value_template: >
          {{ states('sensor.bryan_cgm').split()[1] }}
      bryan_cgm_direction:
        value_template: >
          {{ states('sensor.bryan_cgm').split()[2] }}
      bryan_cgm_time:
        value_template: >
          {{ states('sensor.bryan_cgm').split()[3] }}

NOTE:
Because it is using the space character as a delimiter, none of the data values are allowed to contain a space. For example, should the direction parameter potentially have a value consisting of two words then you cannot, obviously, use the space character as a delimiter. In that case, the template can be easily modified to use a comma as a delimiter.

I am using my nightscout JSON file to import blood sugar. On top of this I would like to summarize daily insuline usage (basal/bolus) and carbs. Anybody found a way using the api/v1/treatments json to do this?

Highly appreciated!
