Ethernet Component ================== .. seo:: :description: Instructions for setting up the Ethernet configuration for your ESP32 node in ESPHome. :image: ethernet.svg :keywords: Ethernet, ESP32 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. .. code-block:: yaml # Example configuration entry for RMII chips ethernet: type: LAN8720 mdc_pin: GPIO23 mdio_pin: GPIO18 clk_mode: GPIO0_IN phy_addr: 0 # Optional manual IP manual_ip: static_ip: 10.0.0.42 gateway: 10.0.0.1 subnet: 255.255.255.0 .. code-block:: yaml # Example configuration entry for SPI chips ethernet: type: W5500 clk_pin: GPIO19 mosi_pin: GPIO21 miso_pin: GPIO23 cs_pin: GPIO18 interrupt_pin: GPIO36 reset_pin: GPIO22 Configuration variables: ------------------------ - **type** (**Required**, string): The type of LAN chipset/phy. Supported chipsets are: - ``LAN8720`` (RMII) - ``RTL8201`` (RMII) - ``DP83848`` (RMII) - ``IP101`` (RMII) - ``JL1101`` (RMII) - ``KSZ8081`` (RMII) - ``KSZ8081RNA`` (RMII) - ``W5500`` (SPI) 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 `): 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. - **cs_pin** (**Required**, :ref:`config-pin`): The SPI chip select pin. - **interrupt_pin** (*Optional*, :ref:`config-pin`): The interrupt pin. - **reset_pin** (*Optional*, :ref:`config-pin`): The reset 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 ``.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.
