Keep Aqara Hub M100 when its USB-powered controller already runs the supported devices and routines you need. Upgrade to Aqara Hub M3 for useful PoE placement or its documented IR appliance-control role. A larger price and enclosure do not make working automations obsolete. New buyers should choose the controller around its location and the actual job it must do.

Does wired placement solve a real M100 limitation?

M100 documents USB-A power and its Wi-Fi connection. M3 adds a PoE port and also provides its stated USB-C power option. That gives a different placement route where appropriate Ethernet power equipment and cabling exist. PoE is useful when it puts the controller where the home layout needs it, rather than merely adding a connector you never use. Include the power-source requirement and cable path in the configuration. We have not measured range, speed or reliability, so a wired port should not become a claim that every automation will react faster.

Will M3’s IR function get used?

M3 documents IR control with status feedback. Its Matter exposure note limits the supported AC route and warns that functions vary by the integrating app. That is a concrete reason to upgrade when a compatible appliance-control routine is part of the plan. Do not infer equivalent IR functions from M100’s bridge/controller role. Equally, do not assume an IR feature creates a universal controller for every appliance in every platform. Write the target routine before paying for M3, then check the supported scope and physical arrangement for that exact task.

Do both provide useful local automation?

M100 documents local execution for its supported Zigbee and Matter rules, while noting that remote push notifications need cloud connectivity. M3 also documents local automation with a separate internet requirement for cloud notifications. Local operation is already part of the M100 purchase case, so the word local alone is not the upgrade. Keeping a working supported rule can be better value than rebuilding it. Identify the missing function rather than infer that the more expensive hub automatically fixes every connectivity, timing or ecosystem problem.

What must be counted in a real replacement?

M3’s cited adapter note says its specified USB power adapter is not included. A PoE setup has its own suitable power equipment. Compare the configuration you will actually install instead of treating either connector as a complete included supply. A working M100 owner should judge the full replacement purchase and reconfiguration effort. M3’s migration documentation also contains a reconfiguration qualification; it is not a promise that every existing rule moves unchanged. For a first-time buyer, M100 is a focused choice when its supported controller roles and USB placement cover the intended setup.

What is the complete buying cost?

The checked listed hardware reference prices are $29.99 USD and $159.99 USD. The listed hardware difference is $130.00, using the stated configurations and source-check dates. Retailer buttons can lead to a different checkout price. Add the storage, power, compatible controller or installation described above before comparing complete setups. For an existing owner, keeping working equipment avoids the full replacement purchase; the price difference between two new boxes is not the cost of upgrading.
