Home Assistant Power Meter¶

This power meter is designed get power consumption directly from Home Assistant sensor.

To use this package, add the following lines to your configuration file:

This package needs to know which sensor to use to obtain the energy exchanged with the grid. It is expected that this sensor is in Watts (W), positive (>0) when electricity is consumed from the grid, and negative (<0) when electricity is sent to the grid.

This power meter can also provide your solar router with the consumption used by your house. This may be necessary, for example, for calculating the theoretical diverted energy.

The sensor for energy exchange with the grid should be defined by main_power_sensor and the consumption sensor by consumption_sensor in the substitutions section of your configuration, as shown in the example below.
