ZiGate-Ethernet – An ESP32 Ethernet, WiFi, and BLE Gateway with optional Zigbee connectivity

Frédéric Dubois, aka fairecasoimeme, has recently released ZiGate-Ethernet, an home automation gateway based on Espressif Systems ESP32 wireless SoC with Ethernet, WiFi, and Bluetooth LE connectivity.

The gateway can also take an optional PiZiGate+ Zigbee module for support for a wider range of home automation gizmos, and everything is designed to fit in the official Raspberry Pi 4 enclosure.

ZiGate-Ethernet ESP32 gatewayZiGate-Ethernet specifications:

  • Wireless module – ESP32-WROOM-32E with ESP32 dual-core processor, 16MB flash, PCB antenna
  • Connectivity
    • 10/100M Ethernet RJ45 port implemented through LAN8720 as on several other ESP32 Ethernet boards
    • 2.4GHz WiFI 4
    • Bluetooth LE 4.2/5.x
    • Zigbee through PiZiGate+ module with PCB antenna or optional external antenna
  • USB – Micro USB port for power and programming
  • Expansion – 16-pin GPIO header with up to 10x GPIO, 7x ADC, UART, 5V, 3.3V, and GND
  • Misc- Reset and Flash button, ESP32/FTDI UART selection switch,
  • Power Supply – 5V/500mA via micro USB  port
  • Dimensions – 85 × 55 × 15 mm
  • Weight – 50 grams
  • Temperature Range – 0°C – 60°C

An Arduino sketch setting up a web interface for configuration and access to the console can be found on Github, and you’ll get more detailed documentation to get started on Zigate website.

Many CNX Software readers may already use Tasmota software, and the good news is that it can also be installed on the platform, which should not be surprising as we’ve previously seen Tasmota support on Sonff Zigbee Bridge (ESP8266 based), aka Sonoff ZBBridge. ESPHome (for ZBBridge) should also be supported, but the installation instructions may come a little later. Either Tasmota or ESPHome firmware will enable integration with Home Assistant.

The Zigate-Ethernet board is sold for 49 Euros inc. VAT on Zigate.fr online store, with PiZiGate+ Zigbee module adding another 24 Euros, and an external antenna an extra 6 Euros.
