The ``bl0940`` sensor platform allows you to use BL0940 energy monitors sensors with
|
|
ESPHome. These are used in some Tuya-devices (e.g. the power metering BW-SHP10)
|
|
|
|
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. All options from
|
|
:ref:`Sensor <config-sensor>`.
|
|
- **energy** (*Optional*): Use the voltage value of the sensor in kWh.
|
|
All options from :ref:`Sensor <config-sensor>`.
|
|
- **internal_temperature** (*Optional*): The internal temperature value of the sensor in °C.
|
|
All options from :ref:`Sensor <config-sensor>`.
|
|
- **external_temperature** (*Optional*): The external value of the sensor in °C. Often not connected and gives garbage data.
|
|
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.
