Dark Sky not able to convert pressure units from millibars to in Hg

Configuration
1

I’m trying to change the pressure units from millibars to inches HG which I’m much more accustomed. When I check my configurateion, it kepps yelling at me. Can someone see what I may be doing wrong? I’ve copied the template information into my configuration file. It looks like this:

sensor:
  - platform: darksky
    api_key: [redacted]
    monitored_conditions:
      - summary
      - icon
      - nearest_storm_distance
      - dew_point
      - wind_speed
      - wind_bearing
      - pressure
      - precip_type
      - precip_intensity
      - apparent_temperature
    update_interval: 00:15:00
    units: us
  - platform: template
    sensors:
      sensor.dark_sky_pressure:
      friendly_name: Pressure
      unit_of_measurement: 'in Hg'
      value_template: "{{ states('sensor.dark_sky_pressure')|float * 0.02953 }}"

And when I check my config, this is the error I’m getting:

Configuration invalid

ERROR:homeassistant.config:Invalid config for [sensor.template]: [sensor.dark_sky_pressure] is an invalid option for [sensor.template]. Check: sensor.template->sensors->sensor.dark_sky_pressure. (See ?, line ?). Please check the docs at https://home-assistant.io/components/sensor.template/

      value_template: {{ states('sensor.dark_sky_pressure')|float * 0.02953 }}

Successful config (partial)
  sensor.template:

Looking at the states under the developer options, this is what is there:

sensor.dark_sky_pressure	1013.0	attribution: Powered by Dark Sky
unit_of_measurement: inHg
friendly_name: Pressure
icon: mdi:gauge
value_template: {{ states('sensor.dark_sky_pressure'|float * 0.02953 }}

It will not perform the math calculation to covert the pressure. I’m sure it’s something simple but very frustrating. Thanks in advance for help.

Give your sensor a different entity and intent the values 2 spaces more.

  - platform: template
    sensors:
      dark_sky_pressure_hg:
        friendly_name: Pressure
        unit_of_measurement: 'in Hg'
        value_template: "{{ states('sensor.dark_sky_pressure')|float * 0.02953 }}"

Thanks for your response.

sensor:
  - platform: darksky
    api_key: [redacted]
    monitored_conditions:
      - pressure
    units: us
  - platform: template
    sensors:
      sensor.dark_sky_pressure_hg:
        friendly_name: Pressure
        unit_of_measurement: 'in Hg'
        value_template: "{{ states('sensor.dark_sky_pressure')|float * 0.02953 }}"

States shows this:

unit_of_measurement: mbar
friendly_name: Dark Sky Pressure
icon: mdi:gauge

It would be so much easier if there was a unit_of_measurement: for inHg. It would calculate to 29.724898 in Hg. I would eventually like to round this number to 2 decimal places, too if we can get this to work.

Read the template sensor from my first response.

Add round(2) to the template

{{ (states('sensor.dark_sky_pressure')|float * 0.02953) | round(2) }}

My fault, I copied the sensor from the group and did not remove the sensor prefix. I see what I did wrong, thank you for your patience with me.
