The ``selec_meter`` sensor platform allows you to use Selec Modbus energy monitors
(`website <https://www.selec.com/product-details/energy-meter-direct-operated-em2m>`__)
with ESPHome.

Selec EM2M Energy Monitor.
The communication with this integration is done over a :ref:`UART bus <uart>` using :ref:`Modbus <modbus>`.
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 9600.
