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 :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 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``.
|
|
- **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``.
