.. note::
This page is incomplete and could some work. If you want to contribute, please read the
:doc:`contributing guide </guides/contributing>`. This page is missing:
- An image for the front page.
- Images/screenshots/example configs of this device being used in action.
The ``pzem004t`` sensor platform allows you to use PZEM-004T energy monitors
(`website <https://innovatorsguru.com/ac-digital-multifunction-meter-using-pzem-004t/>`__) 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 :doc:`pzemac <pzemac>`.
The communication with this integration is done over a :ref:`UART bus <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.

# Example configuration entry
uart:
tx_pin: D1
rx_pin: D2
baud_rate: 9600
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
:ref:`Sensor <config-sensor>`.
- **power** (*Optional*): Use the (active) power value of the sensor in watts. All options from
:ref:`Sensor <config-sensor>`.
- **voltage** (*Optional*): Use the voltage value of the sensor in volts.
All options from :ref:`Sensor <config-sensor>`.
- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the
sensor. Defaults to ``60s``.
- **uart_id** (*Optional*, :ref:`config-id`): Manually specify the ID of the :ref:`UART Component <uart>` if you want
to use multiple UART buses.
