cod.m ZigBee Coordinator 1.0 (CZC-1.0)#

cod.m ZigBee Coordinator V1.0

Features#

  • CC2652P7 Texas Instruments multiprotocol 2.4GHz radio module
  • ZigBee 3.x, Z-Stack firmware (Koenkk)
  • Compatible with zigbee2mqtt (z2m), Home Assistant (zha), ioBroker, etc.
  • LAN, Wi-Fi or USB mode
  • PoE (802.3af) or USB-C power, <1W power consumption
  • ESP32 open source firmware (cod.m UZG Fork)
  • ZigBee firmware update via network and in future via web interface
  • ESP32 firmware update via web interface or USB-C (Auto-BSL)
  • 3D-printed case (CC-BY-NC-SA)

  • Made in Germany
  • CE, RoHS, WEEE

Installation#

  1. Screw the supplied antenna onto the antenna connection.
  2. Connect the cod.m ZigBee Coordinator to Ethernet and/or USB-C power supply. When using Power over Ethernet*, the USB power supply unit is not required.
  3. The red and green LED on the coordinator light up at startup. When only the green LED is lit, the coordinator is ready for operation.
  4. Get the DHCP IP from your router and access it via the browser: http://192.168.xx.xx/ or use mDNS at http://czc-xxxx.local.
  5. No further configuration is required for operation. However, individual settings and operating modes can of course be set in the web interface.
  6. Continue the setup according to the automation used:

* only in PoE version

Power supply#

The power consumption in PoE mode is ~0.9W, in USB mode ~0.7W.

Power over Ethernet (PoE)#

Power over Ethernet (PoE) 802.3af is only available in the PoE version. USB-C power supply naturally also works with the PoE version. USB-C can be plugged into this PoE version at any time without interruption. When switching from USB-C to PoE power supply, the coordinator restarts, as the PoE interface chip must first negotiate the voltage with the PoE switch.

USB-C#

A USB-C power supply with 5V and minimum 400mA is required. A suitable power supply can be purchased in the cod.m shop: goobay USB-C Charger Set 45298.

LEDs#

The coordinator has three LEDs that indicate the operating status. The LEDs can be controlled separately under the General menu item.

cod.m ZigBee Coordinator V1.0 LED Control

Power LED (green)#

Indicates existing power supply. The power LED can be controlled and deactivated separately via software.

Mode LED (red)#

The red LED lights up when USB mode is switched on. The mode LED can be controlled and deactivated separately via software.

ZigBee LED (yellow)#

This LED is directly connected to the ZigBee module (CC2652P7) and lights up when pairing is switched on, for example. The ZigBee LED can be controlled separately via software.

Push-button#

Various actions can be carried out on the coordinator via the push-button. The easiest way to press the button is with a bent paper clip (or similar).

  • Short press: Activate/deactivate USB mode. Indicated by the illuminated mode LED (red).
  • Hold for 2-4 seconds: LEDs on/off
  • Hold for 4-8 seconds: Activate ZigBee module bootloader
  • Hold >10 seconds: Coordinator reset

Factory settings#

To reset the Coordinator to factory settings, disconnect the Coordinator from the power supply. Then hold the button on the device for >10 seconds while reconnecting the power supply.

  • Disconnect the power supply/PoE
  • Hold the button
  • Connect power to the coordinator, PoE will also work
  • Hold the button till the green and red LED start fashling alternately
  • Release the button
  • Wait for the Coordinator to boot up again
