Calcular o consumo a pagar no ESPhome

[pedroct (Pedro Teixeira)]

Com base na dúvida que vi em https://forum.cpha.pt/t/duvida-template-consumo-tomada/2154 eu gostaria de realizar o cálculo do consumo. Pelo que encontrei, teria que aplicar utilizando o lambda, mas não consegui chegar a nenhum resultado. Não entendi e não aprendi a aplica o cálculo usando o código value_template: "{{ ( float(states.sensor.tomada_quarto_consumo_diario.state) * float(states.input_text.valor_kwh.state) ) | round(2) }}"
Obs.: veja que uso um input_text.valor_kwh para informar o valor da minha tarifa.

sensor:
tomada_quarto_energia_gasta_dia:
friendly_name: “Gasto no dia Tomada Quarto”
icon_template: mdi:cash-usd-outline
unit_of_measurement: ‘R$’
value_template: “{{ ( float(states.sensor.tomada_quarto_consumo_diario.state) * float(states.input_text.text_valor_kwh.state) ) | round(2) }}”

Segue o código referente ao ESPhome:
