Xiaomi No Heartbeats

Hi All,

I’ve looked through the various threads and am struggling to work out my issue. Basically, Openhab is not seeing any of the Xiaomi multicast messages (heartbeat, status updates) - meaning after the initial connect, 5 minutes later everything goes offline.

Appreciate any input/ideas - what I have attempted is below.

Openhab logs:

Testing Attempted

  • Removed/readded the binding and items
  • Checked developer key is correct
  • Run the following commands:
  1. sudo netcat -ulk 9898
    This returns no response, except for the initial send from Openhab to setup
  2. sudo tcpdump -n -p udp dst port 9898
    This sees all the heartbeat/status update messages from the Xiaomi device
  3. sudo netstat -ulptn
    This returns that there is nothing listening on UDP 9898; however there is a udp6 entry for ::::9898
    Additionally, on another pi running homeassistant, there is an entry for udp - this device works fine.

This is running on a Raspberry Pi, connected to ethernet directly. I have a similar pi running homeassistant, which does not have any issue connecting to the Xiaomi sensors (although I am trying to move off it to Openhab).

Did you ever find out what was wrong here? I have the very similar problem now. No heartbeats but I do get data from my temperature sensors. I am trying out some commands I discovered to control the radio and alarm features but get no response from the gateway. I noticed there were no heartbeats.
I have been using miiocli to dig into the problem, but no luck so far.

Same issue with me. In my case, it is due to xiaomi gateway connected to wifi mesh. Meanwhile my openhab is connected to main router. Even though it is same subnet. And when i move the gateway to main router, the issue is solved.

And check also network configuration from AlexxIT
