The ``sdm_meter`` sensor platform allows you to use Eastron SDM modbus energy monitors
|
|
(`website <http://www.eastrongroup.com/product_detail.php?id=170&menu1=&menu2=>`__)
|
|
with ESPHome.

SDM220M Energy Monitor.
|
|
|
|
The communication with this integration is done over a :ref:`UART bus <uart>` using the :ref:`Modbus protocol <modbus>`
|
|
over RS485 wiring. You will need an RS485 to UART converter for communication.
|
|
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.
