Fixed

When you have an appliance which only can be set on and off you can use this mode. You need to supply a single watt value in the configuration which will be used when the device is ON Also we provide an option to define power values for certain entity states.

You can setup sensors both with YAML or GUI. When you use the GUI select fixed in the calculation_strategy dropdown.

Configuration options

Name	Type	Requirement	Description
power	float	Optional	Power usage when the appliance is turned on (in watt). Can also be a template
states_power	dict	Optional	Power usage per entity state. Values can also be a template

Simplest example

powercalc:
  sensors:
    - entity_id: light.nondimmabled_bulb
      fixed:
        power: 20

Using a template for the power value

powercalc:
  sensors:
    - entity_id: light.bathroom
      fixed:
        power: "{{states('input_number.bathroom_watts')}}"

When you don’t have a source entity or helper (ex. input_boolean) to bind on and you just want the power sensor to reflect the template value you can use sensor.dummy as the entity_id

powercalc:
  sensors:
    - entity_id: sensor.dummy
      name: Bathroom lights
      fixed:
        power: "{{states('input_number.bathroom_watts')}}"

Example with standby power

powercalc:
  sensors:
    - entity_id: switch.test
      fixed:
        power: 5
      standby_power: 0.5

Power per state

The states_power setting allows you to specify a power per entity state. This can be useful for example on Sonos devices which have a different power consumption in different states.

powercalc:
  sensors:
    - entity_id: media_player.sonos_living
      fixed:
        states_power:
          playing: 8.3
          paused: 2.25
          idle: 1.5

Warning

Some states you cannot use as they are considered “off” for powercalc. In this case you’ll need to use standby_power. The states which this applies to are off, not_home, standby and unavailable.

You can also use state attributes. Use the | delimiter to seperate the attribute and value. Here is en example:

powercalc:
  sensors:
    - entity_id: media_player.sonos_living
      fixed:
        power: 12
        states_power:
          media_content_id|Spotify: 5
          media_content_id|Youtube: 10

When no match is found in states_power lookup than the configured power will be considered.
