The ``cse7766`` sensor platform allows you to use your CSE7766 voltage/current and power sensors
(`datasheet <http://dl.itead.cc/S31/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
2019-02-17 12:28:17 +01:00
:ref:`Sensor <config-sensor>`.
2018-10-17 21:00:30 +02:00
- **power** (*Optional*): Use the (active) power value of the sensor in watts. All options from
2019-02-17 12:28:17 +01:00
:ref:`Sensor <config-sensor>`.
2018-10-17 21:00:30 +02:00
- **voltage** (*Optional*): Use the voltage value of the sensor in V (RMS).
2019-02-17 12:28:17 +01:00
All options from :ref:`Sensor <config-sensor>`.
2018-12-01 13:19:42 +01:00
- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the
2019-01-06 18:56:14 +01:00
sensor. Defaults to ``60s``.
2018-10-17 21:00:30 +02:00
- **uart_id** (*Optional*, :ref:`config-id`): Manually specify the ID of the :ref:`UART Component <uart>` if you want
to use multiple UART buses.
