This sensor can measure voltage and has two channels for reading current and active power (A & B).

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.
The :ref:`I²C Bus <i2c>` is
required to be set up in your configuration for this sensor to work.

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.

This sensor has two data outputs which both encode values using the frequency of a modulated signal: CF and CF1.
CF's frequency is proportional to the (active) power measured and CF1 is proportional to the current/voltage. Using
the SEL pin, one can choose between which mode to use.
