Convert km to Miles template

Configuration
1

I’ve tested this in the Templates Tab of the developer section

sensor:
  - platform: template
    sensors:
      mazda_miles_range:
      friendly_name: "Mazda Miles Range"
      value_template: "{{ ((float(states('sensor.mazda_cx_60_remaining_range')) / 1.6) | round(0)) }}"
      unit_of_measure: "Mi"

I get the following string result:

sensor:
  - platform: template
    sensors:
      mazda_miles_range:
      friendly_name: "Mazda Miles Range"
      value_template: "221"
      unit_of_measure: "Mi"

I added this to the end of my configuration.yaml:

sensor:
  - platform: template
    sensors:
      mazda_miles_range:
      friendly_name: "Mazda Miles Range"
      value_template: "{{ ((float(states('sensor.mazda_cx_60_remaining_range')) / 1.6) | round(0)) }}"
      unit_of_measure: "Mi"

#  debug: False #(optional)

However, when I check my Configuration in the Developer tools the I just get the spinning circle.

Any suggestion as to what I’m doing wrong.

I intend to use the sensor.mazda_miles_range in a gauge tile.

Did you reload you templates in dev tools ? are there any errors in the log ?

When I look at the options to reload in Dev Tools I don’t see the option for templates at all.

Do I have “install” templates

Maybe its because this is your first one ?

Anything in the log ?

5

Have you only got one sensor: entry in your config.yaml ?

6

Nothing seems to get added to the logs (assuming Settings->System->Logs->View Full Logs - Just go an ongoing spinning circle when checking configuration.

I have only 1 sensor entry in my configuration.yaml

Does it pass the test without the sensor in ?

If I comment out all the lines, yes it passes without problem.

I’ve got something in the log which could possibly relevant…

should be unit_of_measurement

10

Also, thats the legacy template format, this is the newer one:

template:
  - sensor:
    - name: "Mazda Miles Range"
      state: "{{ states('sensor.mazda_cx_60_remaining_range') | float(0) / 1.60934 | round(0) }}"
      unit_of_measurement: "Mi"
11

Thanks - That seems to have solved it.

I must have been following an old recipe.

Final code in configuration.yaml

I think I need the unique ID for using this in other areas.

template:
  - sensor:           
    - name: "Mazda Miles Range"     
      unique_id: 'mazda_miles_range'                                                             
      state: "{{ ((float(states('sensor.mazda_cx_60_remaining_range')) / 1.60934) | round(0)) }}"         
      unit_of_measure: "Mi"

Needs to be unit_of_measurement

14

Just looking at this as I needed the same thing.

I see an odd result

input value 242 from sensor

if I round (0) I get 121
if I round (1) I get 151.25

15

I came across this page and saw the last comment, be careful not to round the 1.6!

{{ (states('sensor.my_vehicle_range_kms') | float / 1.60934) | round(0) }}
