SR-MT9101SAC-HP-SWITCH-B 概述
An in-wall smart relay (also called a smart switch module or in-line relay) is a wireless-controlled switching device installed inside a wall outlet or junction box to provide remote on/off control of a connected load. Smart relays sit at the appliance/lighting tier of the home-automation hierarchy (load -> smart relay -> wireless protocol -> border router -> cloud/ecosystem -> user app/voice assistant). Unlike Wi-Fi smart plugs, Thread-based relays use a low-power IEEE 802.15.4 mesh that requires a Thread Border Router (for example, Apple HomePod mini, Google Nest Hub, or Amazon Echo with Thread support) to communicate with the home Wi-Fi and the user's preferred Matter ecosystem.
Key features include 16 A relay contact rating, 100-240 VAC universal mains input, Matter-over-Thread primary radio, plus a ZigBee 3.0 fallback radio for dual-protocol operation. The module requires a neutral wire (N) for powering its radio and control circuitry, and pairs by scanning a Matter QR code printed on the device. Once commissioned, the relay can be exposed to Apple Home, Amazon Alexa, Google Home, and SmartThings simultaneously through standard Matter multi-admin capability, and can additionally be controlled by ZigBee coordinators thanks to the dual radio.
The device integrates a 16 A latching or non-latching mechanical relay with zero-cross switching for reduced inrush stress, an AC-DC converter for internal power, and a multi-protocol SoC running both a Matter (Thread) stack and a ZigBee 3.0 stack on the same module. The on-board firmware supports OTA updates via Thread and ZigBee, allowing manufacturers and integrators to push compatibility fixes. A small status LED reports pairing state and current load condition during commissioning.
Typical applications include retrofitting smart on/off control into existing wall switch boxes for ceiling lights, fans, and AC outlets, and building energy-management systems where a compact 16 A relay with both Matter and ZigBee support is required. Because the module is rated for high inrush loads (up to 3680 W incandescent / 1220 W LED), it is well suited to both resistive lighting and motor loads.
When designing with this device, ensure the wall box has sufficient depth for the module body, provide a reliable neutral connection, and verify that the installation site has adequate Thread mesh coverage or a nearby ZigBee coordinator for commissioning.

典型应用
SR-MT9101SAC-HP-SWITCH-B 适用于 6 应用s: In-Wall Retrofit Smart Lighting, Smart Appliance and Outlet Control, Voice-Controlled Smart Home Ecosystem Integration, Hotel and MDU (Multi-Dwelling Unit) Room Control, Home Assistant / Open-Source Smart Home Bridge, Energy Monitoring and Demand-Response Retrofit.
In-Wall Retrofit Smart Lighting
The SR-MT9101SAC-HP-SWITCH-B is designed for retrofit installation behind an existing mechanical wall switch to add smart on/off control of ceiling or wall lighting without disturbing the visible switch plate. With a 100-240 VAC universal input and a 16 A / 3680 W incandescent (1220 W LED) switched output, it handles the most common residential lighting loads across both 120 V (US) and 230 V (EU/AU) mains. Unlike a Wi-Fi smart bulb, this in-line relay keeps lighting functional with the original wall switch and works in concert with Matter/Thread ecosystems, making it ideal for retrofit projects where re-wiring is undesirable.
推荐
Smart Appliance and Outlet Control
Smart outlets and under-sink appliance circuits benefit from the SR-MT9101SAC-HP-SWITCH-B's 16 A high-current capacity and dual-protocol radios. The module can switch loads such as coffee makers, beverage coolers, exhaust fans, and heated towel rails on schedules or via Matter scenes. The 1220 W LED rating provides ample headroom for LED-driver-inrush surges typical of modern appliance SMPS power supplies, while the integrated ZigBee 3.0 radio ensures compatibility with legacy ZigBee hub installations during a phased migration to Matter.
推荐
Voice-Controlled Smart Home Ecosystem Integration
When commissioned into a Matter ecosystem (Apple Home, Google Home, Amazon Alexa, SmartThings), the SR-MT9101SAC-HP-SWITCH-B becomes controllable via Siri, Google Assistant, and Alexa voice commands. The dual-radio design (Matter-over-Thread primary, ZigBee 3.0 secondary) means a single hardware SKU bridges legacy ZigBee and modern Matter installations without ripping-and-replacing coordinators, ideal for a mixed-vintage smart home where the existing ZigBee backbone must be retained alongside new Thread devices.
推荐
Hotel and MDU (Multi-Dwelling Unit) Room Control
In hospitality and apartment installations, the SR-MT9101SAC-HP-SWITCH-B drives high-inrush loads such as corridor lighting, bathroom heat lamps, and AC outlet control on a per-room basis, while remaining centrally manageable via a property-wide Matter or ZigBee network. The compact in-wall form factor adapts to standard EU/US/AU wall boxes, and the 16 A relay tolerates the inductive inrush of larger lighting transformers used in hotel corridors. Property managers can roll out over-the-air firmware updates over Thread or ZigBee without physical access.
推荐
Home Assistant / Open-Source Smart Home Bridge
Open-source enthusiasts can commission the SR-MT9101SAC-HP-SWITCH-B into Home Assistant via either Matter integration (paired through an OTBR dongle such as Home Assistant SkyConnect) or the native ZigBee Home Automation (ZHA / Zigbee2MQTT) integration. Per the Home Assistant community thread on Thread smart relays (2026-01-17), the device joins a Thread network alongside other OpenThread Border Routers and can be exposed as a switch entity to Home Assistant with full on/off telemetry and firmware-OTA channels.
推荐
Energy Monitoring and Demand-Response Retrofit
Although the SR-MT9101SAC-HP-SWITCH-B is primarily a switching relay, its Matter Smart Home device-type exposes instantaneous on/off state and accumulated runtime to compatible Matter energy-management apps. Building on its 16 A contact rating, the device can be deployed at circuit level to schedule or shed non-essential loads during peak demand periods in residential demand-response programs. Pairing with a Matter energy-management app gives the homeowner a coarse load-by-load breakdown without installing dedicated energy-metering CTs.

- 2-channel option available in same MT series form factor （对比 SR-MT9041A-R)
设计说明
The SR-MT9101SAC-HP-SWITCH-B requires a neutral wire to power its radio and microcontroller; do NOT install it in switch boxes that lack a neutral conductor, as the relay electronics will fail to boot. For 'no-neutral' retrofit scenarios (older US switch loops), use Sunricher's specific no-neutral SKUs or specify a different vendor. Estimated by integrator reference - confirm with the installation manual before wiring.
Although rated 16 A continuous, de-rate by 20% for sustained loads inside an enclosed wall box where ambient can exceed 40 C (e.g., near roof cavities or grouped with other relays). At full 16 A on a 230 V circuit (3680 W) the relay contact heating is significant; ensure adequate ventilation around the module. Estimated: 16 A continuous at 230 V produces approximately 5-8 W of contact dissipation; de-rated to 13 A for closed-junction-box installs per common practice.
When commissioning the SR-MT9101SAC-HP-SWITCH-B, position the wall box within reliable Thread mesh range of at least one other mains-powered Thread device (router). If commissioning fails intermittently, add a Sunricher SR-2421-MT1 Thread-DALI bridge or any other mains-powered Sunricher Thread relay to bolster the mesh. The Matter commissioning QR code is printed on the module housing - photograph it before snapping the module into the wall box.
LED-driver inrush can exceed 100 A peak on cold-start; the SR-MT9101SAC-HP-SWITCH-B is rated for 1220 W LED (about 5.3 A continuous on 230 V) but its relay contact can handle the brief inrush surges. Do NOT exceed the 16 A absolute rating with capacitive loads (large LED arrays on a single driver), as the AC capacitor inrush will pit the contacts over time. For larger LED installs, use the dual-channel SR-MT9041A-R to split the load across two relay contacts.
