ZB-GW03 eWeLink Ethernet Zigbee Gateway now hacked with Tasmota and ESPHome so can be used via MQTT or as a remote Zigbee LAN adapter with Home Assistant's ZHA integration or Zigbee2MQTT

Where can I find the router firmware?

Here is a guide for ESPHome on converting from Zigbee Coordinator into a Zigbee Router device:

• esphome-zb-gw03/docs/router.md at cbf58061007b8571b726046d35d86e3269237787 · syssi/esphome-zb-gw03 · GitHub
  • Prerequisite: esphome-zb-gw03/docs/flashing.md at cbf58061007b8571b726046d35d86e3269237787 · syssi/esphome-zb-gw03 · GitHub

Steps will be almost the same as for the original Sonoff Zigbee Bridge so for Tasmota can follow this:

  • in combination with: A Wired Sonoff Zigbee Alternative – The Helpful Idiot

PS! Just to clarify one thing; note that once you have flashed the EFR32MG21 module with Zigbee Router firmware then it will only act a Zigbee Router, thus there will be no LAN-network connection to the Zigbee chip, and that works disconnected from the LAN-network. So do not think that you can use it as a Zigbee extender over your LAN-network, that is not possible to achieve with Zigbee. If you have two separate locations then you either need to use two completly separate Zigbee networks, or you can use loads and loads of Zigbee Router devices that act as repeaters to cover the entire area between the Zigbee Coordinator and the end device, (it is not possible to bridge the gap by converting Zigbee to IP and then back again to Zigbee within the same Zigbee network). For more tips on extending a Zigbee network see all the tips in this guide:

So in my case is better to use as a second gateway in two separate zigbee networks.

But there is no other module to work as router and over LAN?

Thanks for the clarification

You can’t route Zigbee packets over Ethernet.

As stated above, you have two areas which are too far away to use Zigbee Router devices then you need to setup two completly seperate Zigbee networks, so yes that means seperate gateway and seperate Zigbee Coordinator, (which will have nothing to do with each other at the Zigbee level). If you for example use two separate Zigbee2MQTT installations at both locations then you can still control both using MQTT (which is controlled at the application level, and not at the Zigbee level).

No, none. That is not a feature/funtion in the current Zigbee specification. So not possible at all today.
