Support Mijia Gateway 3? (Device ZNDMWG03LM)

[Eckart0]

Hi, is there an update planned for the new mijia gateway? (Item ZNDMWG03LM)? It seems to be more difficult to enable the LAN mode. I found a desc in [https://community.home-assistant.io/t/xiaomi-mijia-smart-multi-mode-gateway-zndmwg03lm-support/159586/75], and a workaround via Apple Homekit, but I'd prefer a direct integration in iobroker. Regards, Eckart

Hi, that would interest me too. I have the gateway and cannot use it like that.

Any news on this at all? Or maybe a different way to get the key?

Hi .. same issue here ... with Xiaomi Gateway 3 (ZNDMWG03LM) ordered on Aliexpress .... Works fine with Xiaomi App .. but not possible to add to ioBroker .... No "About" menu in app to read key, nor a switch to activate LAN-MODE in App .. I've found partial possts where the soldering is feasible, but RX connectivity ... (https://forum.iobroker.net/user/coupeaze) .. I presume no one was yet able to get this new device connected with ioBroker yet ?

Hi, I have the EU Version Xiaomi Smart Multimode Gateway (ZNDMWG02LM) https://www.amazon.de/gp/product/B082XCWH71/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

There is also no option to enable the LAN Mode in the Xiaomi App and I can't get the key. So I connected the Serial convertor to UART Ports and came to the Bootloader. There is a way to get the telnet password (the EU version ist protected with an Password). After I got the password, I activated the telnet with miio commands and bekame a connection to the gateway over telnet. In the file /data/miio/device.conf you can find the DID and the KEY. But there is an other Problem. The Firmware VERSION=1.4.6_0043 has no option to enable the LAN Mode. There is no service on the device to open the port 9898. :-( This port is needed for ioBroker.

I will trie to flash an older Firmware and test again.

@lastoks Hi, if it works, it would be nice if you could write instructions on it. I have the same gateway, but directly from China. Unfortunately, it's so completely useless to me. Thank you

Hi @Der-Noeri, you can find the intruction here: https://github.com/serrj-sv/lumi.gateway.mgl03/tree/main/uart_recovery. But this firmware works only with Home Assistent, because they get the data over telnet and need a open telnet port.

The modified firmware has the following features:

Based on official 1.4.7_0065, built by @zvldz
List of modifications:
    enabled 'telnetd'
    disabled gen password
    removes password if exists
    mosquitto port is open for access
    run on startup '/data/run.sh'
    added 'curl'
    added 'dropbear' (to start add in '/data/run.sh' line '/bin/dropbear -R -B')
    replaced 'silabs_ncp_bt' with modified version (works without internet)

Actually I know no way to open the port 9898. I don't know, if there is an other way to get the data from the gateway without the port 9898. A translation from https://github.com/AlexxIT/XiaomiGateway3 to the ioBroker adapter could be a way.

Or install a Home Assistant instance with the modified gateway and connect Home Assistence to ioBroker. Not a nice way, but it could work...

Here you can find the desciption how it works with Home Assistant https://gadget-freakz.com/xiaomi-gateway-3-highly-hackable/

Now, we need someone who build an adapter like the Home Assistant https://github.com/AlexxIT/XiaomiGateway3

I installed a HASS instance and successfully connected the XIAOMI EU Gateway v3 (ZNDMWG02LM) with hacked telnet account. Then I connected the HASS instance with the ioBroker adapter https://github.com/ioBroker/ioBroker.hass. Now, I have the Xiaomi temperature and humidity sensors in ioBroker.

It's a quick and dirty workaround... => von hinten durch die Brust ins Auge...
