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.
ESPHome. This sensor is commonly found in Sonoff POW R2. CSE7759B is similar to CSE7766
and works with this integration.
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.

ESPHome. This sensor is commonly found in Sonoff POWs. CSE7759 and BL0937 are similar to HLW8012
and work with this integration. Beware that CSE7759B is different and should be used
with the :doc:`CSE7766 <cse7766>` integration.
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
