I need help!!! How could I add more energy devices to verify when I pass a 3kw power? I need to plus washing machine, dishwasher, oven and drier machine sensors in just one sensor to monitor power consumption. Thank you everybody

By using a template sensor

- platform: template
       unit_of_measurement: "W"
       value_template: "{{ (states('sensor.sensor1') | float) + (states('sensor.sensor2') | float) + (states('sensor.sensor3') | float)}}"

Thank you man, tested and works fine.
