Issues with my template sensors. Please help

Configuration
1

Hi all. new to this. have been going back and forth from search’s trying to fix this so sorry if it has been covered before.

I have 2 template sensors I am trying to get working. the first is a subtraction between 2 sensors.

self_consumption:
        value_template: '{{ (states.sensor.energy_generation | float ) -  (states.sensor.grid_sold_energy_day | float)}}'
        friendly_name: "self_consumption"
        unit_of_measurement: "kWh"

and the problem is it returns 0 and in the template tool I get “This template does not listen for any events and will not update automatically.” This is probably easy but I am a little fried from trying to work it out.

the second is a multiplication of a sensor and a value.

      dryer_consumed_kW:
        value_template: "{{ states('sensor.dryer_electric_consumed_w') | float * 0.001 }}"
        friendly_name: "dryer_consumed_kW"
        unit_of_measurement: "kW"

this seems to be ok in the template builder but when doing a configuration check I get a big error.

Invalid config for [sensor.template]: invalid slug dryer_consumed_kW (try dryer_consumed_kw) for dictionary value @ data[‘sensors’]. Got OrderedDict([(‘power_consumption’, OrderedDict([(‘value_template’, “{% if is_state_attr(‘sensor.pvoutput’, ‘power_consumption’, ‘NaN’) %}0{% else %}{{ state_attr(‘sensor.pvoutput’, ‘power_consumption’) }}{% endif %}”), (‘friendly_name’, ‘Using’), (‘unit_of_measurement’, ‘Watt’)])), (‘energy_consumption’, OrderedDict([(‘value_template’, ‘{{ “%0.1f”|format(state_attr(“sensor.pvoutput”, “energy_consumption”)|float/1000) }}’), (‘friendly_name’, ‘Used’), (‘unit_of_measurement’, ‘kWh’)])), ('power_… (See ?, line ?).

Anyway hope you guys can point me in the right direction.

First one, you are not accessing the entity states correctly, should be:

      self_consumption:
        value_template: "{{ states('sensor.energy_generation') | float  -  states('sensor.grid_sold_energy_day') | float)}}"
        friendly_name: "Self Consumption"
        unit_of_measurement: "kWh"

See here for more info: https://www.home-assistant.io/docs/configuration/templating/#states pay particular attention to the warning.

Second one you got the state correctly but dont use capital letters for the slug (as it says in the error):

      dryer_consumed_kw: # lower case only, no spaces or special characters other than _
        value_template: "{{ states('sensor.dryer_electric_consumed_w') | float * 0.001 }}"
        friendly_name: "Dryer Consumed kW" # can contain any character
        unit_of_measurement: "kW"

Thank you. I know it would be something simple. I see what i did wrong in the first one but not the second one. Will have a good look tonight when I get all the kids to bed.

Once again thank you.

Yours:

dryer_consumed_kW:
                ^--- capital letter

Mine:

dryer_consumed_kw:
                ^--- lower case

Thanks for that.
