Nightscout plugin, show mmol/l

Hi, I use this plugin Nightscout - Home Assistant

Would it be possible to add the option to display values in mmol/l? In Europe we use mmol/l mainly.

Has anyone found a solution yet?

It’s an old topic, but one of the first one that shows up on web searches so I’ll post my solution here.

I added this in my templates.yaml

- sensor:
    - name: blood_sugar_mmol
      state: "{{ ((states.sensor.blood_sugar.state | int)/18) | round(1) }}"
      icon: mdi:water
