Hi guys, I have been reading for a couple of days but only for the Gateway 3 it seems to be there is a solution. Is there any hope for activating LAN access for the DGNWG02LM? I cannot find a way to integrate my door sensors into HA. I tried Xiaomi Miot but it gives ma a lot of strange false events and I understand polling it not the best option for binary sensors.
Currently the gatway is running 1.4.1_176
Update:
So the solution: You do not need to downgrade. Just open 3 screws, solder 3 wires and send 1 command to the gateway to open the LAN port. I bought a cheap CP2102 USB to UART adapter and used putty.
Speed 115200.
First you need an (old) android phone to side load an old version of the Xiaomi home app, I used Version 5.1.37
There you also see the password which you need later for home assistant.
Send the command a couple of times just to make sure
1 psm-set network.open_pf 3
Just do NOT hard reset the gateway or it will close the port again.
You can then test the port if you want, on linux (fedora)
sudo nmap -sU -p9898 192.168.178.31
