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 integration is done over a UART bus. 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.

# Example configuration entry
  rx_pin: D1
  rx_pin: D2
  baud_rate: 9600
  stop_bits: 2

  - platform: pzemdc
      name: "PZEM-003 Current"
      name: "PZEM-003 Voltage"
      name: "PZEM-003 Power"
    update_interval: 60s

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.
  • 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.
