|
|
This ESPHome component enables *wired* Ethernet connections for ESP32s.
|
|
|
|
Ethernet for ESP8266 is not supported.
|
|
|
|
This component and the Wi-Fi component may **not** be used simultaneously, even if both are physically available.

|
RMII configuration variables:
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
- **mdc_pin** (**Required**, :ref:`config-pin`): The MDC pin of the board.
|
|
Usually this is ``GPIO23``.
|
|
- **mdio_pin** (**Required**, :ref:`config-pin`): The MDIO pin of the board.
|
|
Usually this is ``GPIO18``.
|
|
- **clk_mode** (*Optional*, string): The clock mode of the data lines. See your board's
|
|
datasheet for more details. Must be one of the following values:
|
|
|
|
- ``GPIO0_IN`` (Default) - External clock
|
|
- ``GPIO0_OUT`` - Internal clock
|
|
- ``GPIO16_OUT`` - Internal clock
|
|
- ``GPIO17_OUT`` - Internal clock
|
|
|
|
- **phy_addr** (*Optional*, int): The PHY addr type of the Ethernet controller. Defaults to 0.
|
|
- **power_pin** (*Optional*, :ref:`Pin Schema <config-pin_schema>`): The pin controlling the
|
|
power/reset status of the Ethernet controller. Leave unspecified for no power pin (default).
|
|
|
|
SPI configuration variables:
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
- **clk_pin** (**Required**, :ref:`config-pin`): The SPI clock pin.
|
|
- **mosi_pin** (**Required**, :ref:`config-pin`): The SPI MOSI pin.
|
|
- **miso_pin** (**Required**, :ref:`config-pin`): The SPI MISO pin.

|
|
- **clock_speed** (*Optional*, float): The SPI clock speed.
|
|
Any frequency between `8Mhz` and `80Mhz` is allowed, but the nearest integer division
|
|
of `80Mhz` is used, i.e. `16Mhz` (`80Mhz` / 5) is used when `15Mhz` is configured.
|
|
Default: `26.67Mhz`.
|
|
|
|
Advanced common configuration variables:
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
- **manual_ip** (*Optional*): Manually configure the static IP of the node.
|
|
|
|
- **static_ip** (**Required**, IPv4 address): The static IP of your node.
|
|
- **gateway** (**Required**, IPv4 address): The gateway of the local network.
|
|
- **subnet** (**Required**, IPv4 address): The subnet of the local network.
|
|
- **dns1** (*Optional*, IPv4 address): The main DNS server to use.
|
|
- **dns2** (*Optional*, IPv4 address): The backup DNS server to use.
|
|
|
|
- **use_address** (*Optional*, string): Manually override what address to use to connect
|
|
to the ESP. Defaults to auto-generated value. For example, if you have changed your
|
|
static IP and want to flash OTA to the previously configured IP address.
|
|
- **domain** (*Optional*, string): Set the domain of the node hostname used for uploading.
|
|
For example, if it's set to ``.local``, all uploads will be sent to ``<HOSTNAME>.local``.
|
|
Defaults to ``.local``.
|
|
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
|
|
|
|
|
|
.. note::
|
|
|
|
If your Ethernet board is not designed with an ESP32 built in, it's common to attempt
|
|
to use flying leads, dupont wires, etc. to connect the Ethernet controller to the ESP32.
|
|
This approach is likely to fail, however, as the Ethernet interface uses a high frequency
|
|
clock signal that will not travel reliably over these types of connections. For more
|
|
information and wiring details refer to the link in the *See also* section.
|
|
|
|
.. note::
|
|
|
|
SPI based chips do *not* use :doc:`spi`. This means that SPI pins can't be shared with other devices.
