Hub 3 clearly wins in certain areas.
2. Bluetooth mesh.The Hub 3 itself is a mesh backbone, and the Curtain 3, which used to lose connection at the end of the corridor, can now maintain a connection through any Bot or Hub in the middle as a relay.
3. Physical knob.Adjusting brightness, curtain opening/closing, and switching ambient volume can all be done without opening the app. Small changes, but a huge difference in daily user experience.
4. Long-term resilience.Matter 1.4 supports the new device types (energy management, electric vehicle charging piles) which will be prioritized for Hub 3. Hub 2 is limited by memory and is almost certain to miss out on the new features of Matter 1.4.
Hub 2's remaining advantages
The core functions are the same.If you only need an infrared remote control for an old air conditioner / TV, along with two Bot Matter bridges, Hub 2 is completely sufficient.
Hub 2 is already showing signs of fatigue by 2026.
Community opinion turned negative.Reddit users are increasingly using the phrase "upgraded and left" to describe Hub 2 (originally: "the others are junk, hub 3 wins」)。
No mesh.Accessories at the edge of the Bluetooth signal may intermittently disconnect.
Real-world scenarios
Scenario A — Renter, 1 room, only 2 accessories
Hub Mini Matter (£29) is sufficient. Only consider Hub 3 for future expansion if you also want to measure temperature and humidity.
Scenario B — Owner, 2 bedrooms, 6–10 SwitchBot devices
Go straight to Hub 3.Hub 2's device limit will restrict you to a maximum of one year.
Scenario C — Home Assistant / Apple Home Advanced User
Hub 3。Matter 1.4 stacking and seamless integration of the Matter server with HA and the iOS 18 Home App; Hub 2 requires more bridge-side adjustments.
Final Recommendation
In 2026, almost all buyers should choose Hub 3. Spending an extra A$30 / £31 will get you a model that will be "contemporary mainstream" for the next 24–30 months, avoiding the need to buy a second unit after the smart home expansion.
