Multi Switch

1.14 or higher

The multi switch strategy allows you to combine the self usage of multiple switches into a single entity. This can be used for example to make a profile for Tp-Link HS300 power strip.

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

Configuration options

Name Type Requirement Default Description
entities list Required Provide a list of the individual switch entities
power decimal Required Power for one outlet when it is switched on
power_off decimal Required Power for one outlet when it is switched off 
powercalc:
  sensors:
    - name: "My outlet self usage"
      multi_switch:
        entities:
          - switch.outlet_1
          - switch.outlet_2
          - switch.outlet_3
        power_off: 0.25
        power: 0.5

In this example, when all the switches are turned on, the power usage will be 0.5W * 3 = 1.5W When only switch.outlet_1 is turned on, the power usage will be 0.5W + 0.25W + 0.25W = 1W
