Emulated Kasa

The Emulated Kasa integration emulates a TP-Link Kasa smart plug and announces the power usage of configured devices to any that might request it on the local network.

For example, the Sense Energy Monitor can use this to identify power usage.

The configuration includes a list of entities to expose with attributes for the published name and current power usage. If the entity is a sensor or has a current_power_w attribute (such as in a smart switch), that value will be reported as the current power usage unless the power field is defined. The power field can contain a hardcoded value, a sensor, or a template (see configuration example).

The provided power unit must be the current power usage in Watts. Values of kW can be converted, but the values of kWh cannot be used.


This integration requires the entities exposed to be listed in your configuration.yaml file:

# Example configuration.yaml entry
      power: 40.2

Configuration Variables

entities map Required

A list of entities exposed.

name string (Optional)

Name visible to external devices.

power integer | float | template (Optional)

The current power usage in watts. This can be set to a static value or a template.

power_entity string (Optional)

A sensor measuring the current power usage in watts.

A full configuration sample looks like the one below.

# Example configuration.yaml entry
    # uses the current_power_w attribute of the switch
      name: "A/C"
    # uses the sensor state value
      name: "Power Meter"
    # uses static value
      name: "Dining Room Lights"
      power: 40.2
    # uses template based on state of device
      power: >-
                {% if is_state_attr('fan.ceiling_fan','speed', 'low') %} 2
                {% elif is_state_attr('fan.ceiling_fan','speed', 'medium') %} 12
                {% elif is_state_attr('fan.ceiling_fan','speed', 'high') %} 48
                {% endif %}
    # uses value from 3rd party sensor
      name: "Strip Lights"
      power_entity: sensor.light_power_w
    # uses template to convert device state into watts
      name: UPS Power
      power: "{{ float(states('sensor.ups_kw')) * 1000 }}"
