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.

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.

------------------------
|
|
|
|
|
|
|
|
|
|
- **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.
