On September 30, 2026, Zemismart announced two Zigbee LED-strip controllers that it says can expose compatible lighting to Matter ecosystems through its M1 Pro or M6 gateway. The important distinction for installers is that these are Zigbee controllers behind a bridge, not native Matter-over-Thread devices. That affects the hardware list, setup path and features worth testing before a project is specified.
What Zemismart announced
The company announcement names a dual-white CCT controller, ZMZ-03SL(CW), and an RGB-plus-tunable-white controller, ZMZ-03SL. Both are described for compatible 12V or 24V DC LED strips, with an external Zigbee antenna and brightness adjustment. The CCT product page lists a 2700K–6500K white range. The RGBCCT page describes color plus tunable white. Those figures are vendor specifications, not results of independent testing.
Zemismart says either Zigbee controller can be paired to a compatible M1 Pro or M6 Matter gateway and then made available to Apple Home, Google Home, Alexa, SmartThings or Home Assistant. Its announcement separately asks users whether direct pairing with third-party Zigbee coordinators, including Zigbee2MQTT or ZHA, should be prioritized. That request is a useful limit on the announcement: it is not confirmation that every third-party coordinator already supports these exact models.
Why the bridge matters
A Matter bridge translates a non-Matter device into an interface a Matter controller can see. Google’s Matter primer describes Zigbee-to-Matter bridging as a supported architecture. Home Assistant’s integration guide cautions that a bridge may expose only some devices or features from its native ecosystem. Therefore, “works through a Matter gateway” should not be read as “every function works identically in every app.”
The power supply is another practical difference. These strip controllers use a 12V/24V DC input and control powered LED strips; they are not battery-free wall switches and do not harvest energy from a button press. A wireless wall control, if wanted, is a separate part of the design. The announcement does not demonstrate a particular switch-to-strip pairing, dimming latency or offline behavior, and we have not tested those workflows.
What to verify in a lighting project
Before selecting one of the new controllers, match the strip’s voltage and channel type to the exact controller and power supply. Then confirm the gateway model and firmware, and pair a sample unit in the intended ecosystem. Check whether on/off, brightness, white temperature, color and scenes appear as expected. Vendor app effects such as music sync may not have an equivalent Matter control; verify the desired effect in the actual app instead of assuming it crosses the bridge.
Finally, test the physical control route. Does a wall switch, wireless button or automation still operate the lights when internet service is unavailable? Does dimming look smooth at low output, and do the strips recover the intended state after a power interruption? These are proposed acceptance checks, not claims about Zemismart’s measured performance. The September 30 launch broadens a bridge-based lighting option, but the right specification still depends on the complete controller, gateway, strip and user-interface combination.
