If you now want the router to publish e.g. only Vdd, its IP, and the command line output, set the mqtt_mask to 0x0001 | 0x0002 | 0x0040 (= "set mqtt_mask 0043").
# ENC28J60 Ethernet Support
The esp_wifi_repeater now includes support for an ENC28J60 Ethernet NIC connected via SPI (Thanks to Andrew Kroll https://github.com/xxxajk for his great work on getting right). The Ethernet interface will support about 1 Mbps when the ESP is running an 160 MHz. Switching the AP interface on and using the Ethernet as uplink will turn the esp_wifi_repeater into a cheap AP for WiFi devices (e.g. other ESPs).
The connection via SPI has to be:
```
NodeMCU/Wemos ESP8266 ENC28J60
D6 GPIO12 <---> MISO
D7 GPIO13 <---> MOSI
D5 GPIO14 <---> SCLK
D8 GPIO15 <---> CS
D1 GPIO5 <---> INT
D2 GPIO4 <---> RESET
Q3/V33 <---> 3.3V
GND <---> GND
```
Short and soldered wires work best. In addition you will need a transistor for decoupling GPIO15, otherwise your ESP will not boot any more, see: https://esp8266hints.wordpress.com/category/ethernet/ . Also, it is important to have a good power supply: the ENC28j60 needs about 160mA when active. For me it fails, if I try to use the 3.3V from the ESP board.
Now you can configure the new Ethernet interface:
- set eth_enable [0|1]: enables/disables an ENC28J60 Ethernet NIC on the SPI bus (default: 0 - disabled)
- set eth_ip _ip-addr_: sets a static IP address for the ETH interface
- set eth_netmask _netmask_: sets a static netmask for the ETH interface
- set eth_gw _gw-addr_: sets a static gateway address for the ETH interface
- set eth_dhcpd [0|1]: starts a DHCP server for dynamic IP addresses on the ETH interface, (default: 0 - disabled)
# Power Management
The repeater monitors its current supply voltage (shown in the "show stats" command). This only works, if the 107th byte in esp_init_data_default.bin, named as vdd33_const, is set to 255(0xFF). The easiest way to achive that, is to write esp_init_data_default_v08_vdd33.bin to flash (see below).

If configured correctly, the update will start and the ESP will reboot with the new binary.
# ENC28J60 Ethernet Support (experimental)
If you enable the HAVE_ENC28J60 option in user_config.h and recompile the project, you get support for an ENC28J60 Ethernet NIC connected via SPI.

# Known Issues
- Due to the limitations of the ESP's SoftAP implementation, there is a maximum of 8 simultaniously connected stations.
- The ESP8266 requires a good power supply as it produces current spikes of up to 170 mA during transmit (typical average consumption is around 70 mA when WiFi is on). Check the power supply first, if your ESP runs unstable and reboots from time to time. A large capacitor between Vdd and Gnd can help if you experience problems here.
