Hello, guys! I’m having the same problem.
I got a Xiaomi kit from Amazon (EU version). The gateway is a DGNWG05LM. Here’s a photo of the gateway and the box it came in:
As others have said, there is no “About” option in the gateway settings:
My all version is 5.6.65 and the firmware version of the gateway is 3.4.6_132.
Is there any hope for us? Not even by connecting to the serial port in the board?
