Setting up Matter over Thread should be simple… but as you’ll see in this video, it can turn into a chaotic adventure of pairing loops, missing devices, random discoveries, and the ultimate culprit: IPv6.
In this video, I walk through the entire process of setting up an Aqara Thread Border Router,
pairing a Matter‑over‑Thread smart plug, fixing the dreaded “Something went wrong” errors, and discovering why Home Assistant refused to cooperate until IPv6 was enabled.
You’ll see:
• Installing and setting up the Aqara app
• Pairing the border router
• Home Assistant discovering random devices
• Matter pairing loops and failures
• The hidden IPv6 requirement
• Successfully pairing a Matter Thread plug
• Updating firmware, renaming devices, adding labels, and organising everything
• Final thoughts on Matter, Thread, and border routers
If you’re struggling with Matter, Thread, or Home Assistant pairing issues, this walkthrough will save you hours.
