The pzem004t sensor platform allows you to use PZEM-004T energy monitors (website) sensors with ESPHome.

Warning

This page refers to version V1 of the PZEM004T, which has been out of stock for a while. For using the newer V3 variant of this sensor please see pzemac.

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
uart:
  tx_pin: D1
  rx_pin: D2
  baud_rate: 9600
  stop_bits: 2

sensor:
  - platform: pzem004t
    current:
      name: "PZEM-004T Current"
    voltage:
      name: "PZEM-004T Voltage"
    power:
      name: "PZEM-004T 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 (active) 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.
  • uart_id (Optional, ID): Manually specify the ID of the UART Component if you want to use multiple UART buses.
