Matter Protocol

Matter over Thread

The Sunricher Micro Dimmer SR-MT9040A-S from Sunricher uses Matter over Thread to connect to your smart home. Thread is a low-power mesh network built for devices like a Dimmer Module, Energy Monitor. Devices pass messages to each other, so the mesh gets stronger and reaches further with every router you add.

In a Thread network, the Sunricher Micro Dimmer SR-MT9040A-S works as a Router (FTD).

Border Router (TBR)

A Thread Border Router connects your Thread devices to your home network, so no extra hub is needed.

Router (FTD)

A Thread Router stays powered on and relays messages for other devices, extending the range of your network.

End Device (MTD)

A Thread End Device talks to nearby routers and does not relay messages, which saves power and battery life.

Every Thread router you add makes your mesh stronger and extends its range. See all Thread devices →

Matter Version

Matter 1.1

The Sunricher Micro Dimmer SR-MT9040A-S is certified on Matter 1.1, released in May 2023. This update added no new device types. It improved support for battery-powered devices that sleep most of the time, so they last longer and show as offline less often.
