[SOLVED] Openhab2 - Xiaomi Mi Gateway - does not respond

Hi there,

I´m new in every direction. Nevertheless I managed to buy and install lots of shelly and xiaomi gadgets and get them running on their respective apps. Also I got myself a brand new raspberry 4 with 4GB and managed to get openhab running and the network binding installed, as well as the xiaomi mi smart home binding.

I enabled the developer mode on the xiaomi app (IOS), turned on the access and noted the “password”. I tried to connect the gateway like in this video. However, no thing can be found. I tried manually but with no success.

Eventually I found this thread. I have the xiaomi gateway, not aquara. In the app it says “lumi.gateway.v3”. Next step I´ll try to find out whether port 9898 is open. Although I don´t know how, yet. Any easy description? Additionally I´ll try to find out what the following things mean:

  • nmap
  • putty
  • monkeycom
  • UART
  • tcpdump
  • MQTT

If I find a definition for dummies I´ll share. If there´s is a" how to use", tutorial or something already I appreciate a link.

Meanwhile some questions for you:

  1. If the port 9898 is closed, is soldering and UART the only solution?
  2. I thought of a zigbee stick as an alternative. This thread suggests that a zigbee stick with the zigbee binding is not working well. Is this a good alternative to point 1, or not?
  3. What is zigbee2mqtt? This thread says there is a binding but the addon list does not say so. Is this an alternative and how does it work?
  4. The gateway cannot reach the sensor in the garage. If I read this right, xiaomi range extention is only possible with another xiaomi device with AC power? Correct?

Thanks so far
