IPv6 Requirements for Matter and Thread, Explained
Matter and Thread need IPv6 on your LAN, not from your ISP: link-local and ULA addresses, router advertisements reaching hosts, and unfiltered multicast.
-
Does Matter Work Without Internet? Offline Limits
Previously paired Matter devices retain local control during an outage, while setup, remote access, voice, and many vendor apps rely on cloud services.
-
How Many Thread Border Routers Do You Need?
A single Thread border router connects the mesh, two on the same network add resilience, and additional units should address verified coverage gaps.
-
How to Add a Matter Device to Home Assistant
The guide covers Wi-Fi and Thread prerequisites, companion app commissioning, multi-admin sharing, credential syncing, and common network failures.
-
Matter Multi-Admin Sharing: Fabrics, Codes, and Limits
Matter multi-admin lets one device join separate platform fabrics; the guide covers temporary sharing codes, the five-fabric minimum, and fabric removal.
-
Matter over Wi-Fi vs Thread: Power, Mesh, and Setup
Matter uses the same application layer over Wi-Fi and Thread, while power needs, mesh behavior, IPv6 setup, and border router requirements differ.
-
Matter vs Zigbee vs Z-Wave: Which One to Build a Home On
Matter is an IP application layer, while Zigbee and Z-Wave are complete stacks; this comparison covers radios, range, limits, controllers, and bridges.
-
What Is a Matter Controller? Roles and Multi-Admin
The guide separates controllers, commissioners, administrators, and border routers, then explains fabrics, commissioning, hubs, and multi-admin sharing.
-
Why Matter Devices Keep Going Offline
The guide traces outages to border routers, split Thread networks, sleepy-device subscriptions, multicast or IPv6 filtering, and vendor apps.
-
Matter Pairing Failures: A Systematic Fix List
A layer by layer fix list for Matter commissioning errors: Bluetooth handoff, IPv6 and mDNS discovery, Thread credentials, and exhausted fabric slots.
-
Thread Border Router Guide: Choosing and Placing
What a Thread border router does, which hubs contain one, how many a home needs, and where to put them so the mesh stays reachable and redundant.
-
Thread vs Zigbee: How the Two Meshes Differ
Thread and Zigbee share a radio but split at the network layer. How addressing, roles, controllers and device support differ, and which to build on.
-
How Matter, Thread and Border Routers Fit Together
How the Matter application layer, the Thread mesh beneath it, border routers and multi-admin fabrics stack up, and which layer a fault belongs to.
