I am trying to copy and paste part of a config.yaml file into a new file. This is the clip.

#TempDiff
######
- platform: template
sensors:
temperature_difference:
friendly_name: "Temperature Difference"
unit_of_measurement: '°C'
value_template: >
{{ ( states('sensor.lumi_lumi_weather_temperature')|float(0) - states('sensor.lumi_lumi_weather_b083df07_temperature')|float(0) )|round(2) }}

When I paste it in I get these errors

#TempDiff

######

- platform: template bad indentation of a mapping entry

sensors:

temperature_difference: can not read a block mapping entry; a multiline key may not be an implicit key

friendly_name: "Temperature Difference"

unit_of_measurement: '°C'

value_template: >

{{ ( states('sensor.lumi_lumi_weather_temperature')|float(0) - states('sensor.lumi_lumi_weather_b083df07_temperature')|float(0) )|round(2) }}

What am I doing wrong here?

I'm supposed to respect my elders, but it's getting harder and harder for me to find one now.

Probably need to see the surrounding fragments of yaml since its complaining about indentation. Could be the previous/next fragments change the indentation you need.

Hard to say as the forum software might screw the format, but the indentation below temperature_difference might be wrong, make sure it's at least 2 spaces. Does it validate if you paste the snippet on https://codebeautify.org/yaml-parser-online. ?

It validates in the online parser.

Indentation is important in yaml, keep it consistent at 2 spaces

You’re probably missing
sensor:
Above your
- template

Template sensors changed a while ago
So it might be
template:
-sensor:
-name: “sensor name”
unit_of_measurement: “•c”
Etc….

The first line "-platform: template should have no indentation.

Move the whole lot back to the left (select the text and shift tab):

Tauranga
Quic Fibre (use R213449EPZJ3R for free setup)

Thanks for that, think I am getting close. This is what I am getting now.

I think you are using quite old config. Also i dont believe "sensorS" is correct. should it be "sensor"

Regardless, you can set this up in the UI quite easily - Settings\Devices & Services\Helpers - Create Helper = Template \ Template a sensor

Put your details from the yaml here, State Template will be your value template - if this is all correct it will show you a preview in the same window

OK, I set up a template using the data from my old file. This used to work in my previous HA config to subtract the temperature of one sensor from another to produce the difference between the two.

In the template sensor I have Unit of measurement as degrees C, Device Class as Temperature and State Class as Measurement.

The current values for those sensors are 17.4 and 16.9 respectively so I should get a result of 0.5 but instead I get 17.4.

Can you spot my error?

Many thanks.
