The ``cse7766`` sensor platform allows you to use your CSE7766 voltage/current and power sensors
|
|
(`datasheet <https://itead.cc/wp-content/uploads/2022/05/CSE7766.pdf>`__) sensors with
|
|
ESPHome. This sensor is commonly found in Sonoff POW R2. CSE7759B is similar to CSE7766
|
|
and works with this integration.
|
|
|
|
.. note::
|
|
|
|
SAFETY HAZARD: Some devices such as Sonoff POWs/Shelly/etc, have the digital GND connected directly to mains voltage so **the GPIOs become LIVE during normal operation**. Our advice is to mark these boards to prevent any use of the dangerous digital pins.
|
|
|
|
As the communication with the CSE7766 done using UART, you need
|
|
to have an :ref:`UART bus <uart>` in your configuration with the ``rx_pin`` connected to the CSE7766.
|
|
Additionally, you need to set the baud rate to 4800.

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 V (RMS).
|
|
All options from :ref:`Sensor <config-sensor>`.
|
|
- **energy** (*Optional*): Use the total energy value of the sensor in Wh.
|
|
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.
