Where do you put this code?
I’m new to home assistant and cant understand wich file to put all the code into?

If you are new to HA you probably haven’t edited any yaml files as a lot can be done these days from the Configuration tab, but this needs to go in your configuration.yaml file.

Install the File Editor add-on from the Supervisor add-on store to get started.

zoogara:

- platform: template
    sensors:
      man_cave_pressure_msl:
        friendly_name: "Man Cave Air Pressure MSL"
        unit_of_measurement: hPa
        value_template: "{{ (states('sensor.man_cave_air_pressure')|float * (1 - (0.0065 * 175) / (states('sensor.man_cave_temperature')|float + (0.0065 * 175) + 273.15)) ** -5.257) | round(1)  }}"

I did a copy and paste of this and just replaced my sensor names and elevation but it returns a value of 0.0?

Hmm. Then one of your sensor values is probably wrong.

Pasting this into your template editor (substituting your sensors and elevation):

{{ states('sensor.man_cave_temperature') }}
{{ states('sensor.man_cave_air_pressure') }}
{{ (states('sensor.man_cave_air_pressure')|float * (1 - (0.0065 * 175) / (states('sensor.man_cave_temperature')|float + (0.0065 * 175) + 273.15)) ** -5.257) | round(1)  }}

Should give a result like:

Result type: string
18.2
1000.2
1020.9
This template listens for the following state changed events:

Entity: sensor.man_cave_air_pressure
Entity: sensor.man_cave_temperature

Also paste your template sensor definition, that you have edited, rather than the one I use - so we can see if any weird typos.
