  • Images/screenshots/example configs of this device being used in action.

The pzemdc sensor platform allows you to use various DC Peacefair PZEM energy monitors with ESPHome. The supported models are: PZEM-003, PZEM-014, PZEM-016 and PZEM-017.

The communication with this component is via a UART. You must therefore have a uart: entry in your configuration with both the TX and RX pins set to some pins on your board and the baud rate set to 9600.

Configuration variables:

  • current (Optional): Use the current value of the sensor in amperes. All options from Sensor.

  • power (Optional): Use the power value of the sensor in watts. All options from Sensor.

  • voltage (Optional): Use the voltage value of the sensor in volts. All options from Sensor.

  • energy (Optional): Use the energy value of the sensor in kWh. All options from Sensor.

  • update_interval (Optional, Time): The interval to check the sensor. Defaults to 60s.

  • address (Optional, int): The address of the sensor if multiple sensors are attached to the same UART bus. You will need to set the address of each device manually. Defaults to 1.

pzemdc.reset_energy Action

This action resets the total energy value of the pzemdc device with the given ID when executed.
