The ``bl0942`` sensor platform allows you to use BL0942 energy monitors sensors with
|
|
ESPHome. These are used in some Tuya-devices (e.g. Aubess Tuya WiFi Mini Smart Switch With Energy Monitor)
|
|
|
|
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 4800 with 1 stop bit.

Configuration variables:
|
|
------------------------
|
|
|
|
- **voltage** (*Optional*): The voltage value of the sensor in Volts.
|
|
All options from :ref:`Sensor <config-sensor>`.
|
|
- **current** (*Optional*): The current value of the sensor in Amperes. All options from
|
|
:ref:`Sensor <config-sensor>`.
|
|
- **power** (*Optional*): The (active) power value of the sensor in Watts. Note that some power meters will report this in negative values (probably wired backwards), so you may want to use a filter to multiply it by -1. All options from :ref:`Sensor <config-sensor>`.
|
|
- **energy** (*Optional*): Use the energy value of the sensor in kWh.
|
|
All options from :ref:`Sensor <config-sensor>`.
|
|
- **frequency** (*Optional*): The frequency value of the sensor in Hertz. All options from
|
|
:ref:`Sensor <config-sensor>`.
|
|
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.
