SR-MT9041A-2R Overview
A smart relay is a wireless, app-controllable switching module installed behind a conventional wall switch that converts a traditional lighting or outlet circuit into a remotely controllable load; it sits within the broader category hierarchy of smart home modules -> in-wall relay modules -> wireless load controllers -> home automation. SR-MT9041A-2R specifically targets Matter-Thread ecosystems while preserving Zigbee interoperability during user transitions between protocols.
Key features include dual independent channels, integrated energy metering reporting active power and accumulated kWh, software-overcurrent and over-temperature cutoff, push-button local control in parallel with cloud/voice/app control, and a working temperature window suitable for indoor flush-mount boxes. The dual-protocol radio allows Touchlink commissioning to a Zigbee remote and QR-code Matter pairing with any Matter-certified border router.
Technically, the module runs on AC mains directly (100-240 VAC, 50/60 Hz) and exposes a low-voltage MCU plus a dual-radio SoC; it uses a triac/relay hybrid output stage rated for resistive, capacitive, and inductive loads. The Zigbee side operates as a Router or End-Device per commissioning, and the Thread side joins an existing Thread mesh via Matter over Thread. Energy metering uses a shunt/transformer front-end with calibration stored in non-volatile memory.
Typical applications include retrofit dual-gang smart lighting control (2 independent lamp circuits), smart outlet/fan control in residential and hospitality settings, energy-monitoring smart switches for whole-home dashboards, and Matter/Thread mesh expansion via the device's router role (where supported). Sunricher documents the unit as fitting behind standard EU/UK/US flush boxes.
When designing with this module, observe local electrical codes: ensure the input supply is properly disconnected before wiring, verify the box depth accommodates the 16 mm module thickness plus wiring bend radius, and confirm load totals do not exceed 5 A per channel (or the lower 4.3 A figure for capacitive/inductive loads). Pairing mode activation and Touchlink behavior are documented in the user manual.

Typical Applications
SR-MT9041A-2R is suitable for 8 applications: Retrofit Dual-Gang Smart Lighting Control, Smart Outlet / Smart Plug Retrofit Module, Matter/Thread Mesh Expansion for Smart Homes, Hospitality / Hotel Room Switch Retrofit, Whole-Home Energy Monitoring Dashboard, Voice-Controlled Lighting via Alexa / Google Home, Fan / Inductive Load Smart Control, Matter Multi-Ecosystem Residential Installations.
Retrofit Dual-Gang Smart Lighting Control
The SR-MT9041A-2R's two independent 5 A channels are ideal for retrofit dual-gang lighting circuits, where each gang needs independent on/off control without rewiring. Rated 100-240 VAC at 50/60 Hz, the unit accepts mains directly and switches two separate lamp circuits while reporting per-channel energy. Its 42 x 38 x 16 mm footprint fits behind standard EU/UK flush boxes. Compared with Wi-Fi-only relays, the dual Matter over Thread + Zigbee 3.0 radio avoids 2.4 GHz congestion when many rooms are automated.
Recommended
Smart Outlet / Smart Plug Retrofit Module
Mounted behind a wall outlet, the SR-MT9041A-2R provides remote on/off and energy metering for a hard-to-reach appliance circuit (e.g., a printer, aquarium, or holiday lighting). Per-channel 5 A resistive and 4.3 A inductive ratings cover most household appliances. The built-in energy metering lets the user track kWh per outlet in Apple Home or SmartThings dashboards, enabling usage-based automation. Overload and overheat protection cut the load if a fault develops.
Recommended
Matter/Thread Mesh Expansion for Smart Homes
When configured with router capability on either protocol, the SR-MT9041A-2R doubles as a Thread/Zigbee mesh extender, hardening the wireless backbone of a Matter-over-Thread smart home. Each wall-switch deployment adds another node inside the home's 2.4 GHz mesh, extending range for battery sensors and remote controls. Builders specifying this module get dual control AND wireless infrastructure in one device. A compatible Thread border router (Apple TV, Echo, Nest Hub) is still required for Thread uplink.
Recommended
Hospitality / Hotel Room Switch Retrofit
Hotels and serviced apartments use the SR-MT9041A-2R to convert guest-room lighting into Matter-controllable scenes (reading, all-off, welcome, do-not-disturb) without disturbing existing switch wiring. Dual isolated channels drive a corridor and bedside lamp separately, with push-button local override for guests. Energy metering lets managers track per-room consumption. Universal 100-240 VAC input suits global deployments with one SKU.
Recommended
Whole-Home Energy Monitoring Dashboard
When paired with Home Assistant, Apple Home, or SmartThings, the SR-MT9041A-2R's active-power and accumulated-energy metering data feeds whole-home dashboards, alerting users to vampire loads, abnormal consumption, or stuck-on appliances. Each channel reports independently, so a single in-wall module can monitor two high-draw circuits at once. The overload protection cuts the load if a fault exceeds 5 A, adding a software safety layer.
Recommended
Voice-Controlled Lighting via Alexa / Google Home
After pairing through a Matter-over-Thread border router (Echo 4th-gen, Nest Hub Max, Apple HomePod mini), the SR-MT9041A-2R's two channels appear as two named lights in the Alexa or Google Home app, enabling voice commands like 'Alexa, turn off the bedside lamp'. The dual-radio design preserves Zigbee 3.0 fallback for legacy hubs, future-proofing the install. Push-button switches still work as manual overrides.
Recommended
Fan / Inductive Load Smart Control
The SR-MT9041A-2R derates to 4.3 A on inductive or capacitive loads, suitable for small ceiling fans, exhaust fans, and low-VA lighting transformers. Its soft-switching relay contacts (per the user manual) reduce inrush stress on motor windings. Channel 1 can drive the fan, Channel 2 the room light, all from a single gang-box retrofit. Overheat protection shuts the unit down if the relay's thermal limit is approached.
Recommended
Matter Multi-Ecosystem Residential Installations
Installers specifying Matter-certified products across diverse customer ecosystems (iOS households, Android households, mixed) use the SR-MT9041A-2R as a universal 2-channel control point because it exposes both channels to Apple Home, Google Home, Alexa, and SmartThings simultaneously. Universal 100-240 VAC input lets one SKU cover EU/UK/AU/North American installations with regional wiring variants. The compact 42 mm length fits shallow US single-gang boxes.

Design Notes
Estimated: The SR-MT9041A-2R is an in-wall AC mains module; it is not a PCB-mount component. Treat wiring as you would any mains device: de-energize the circuit at the breaker before working, confirm the back box has at least 16 mm depth plus enough room for the L/N wire bend radius (typical EU 60 mm back box is sufficient; 45 mm shallow boxes may not fit), and use ferrules on stranded conductors. Torque terminal screws to the manufacturer-rated value, usually 0.4-0.6 Nm.
Even though the module is rated 5 A per channel, simultaneous heavy loads on both channels will raise the internal relay ambient. Derating rules: in enclosed or insulated walls, run the unit at no more than 80% of nameplate per channel (i.e., 4 A resistive per channel). The overheat protection in firmware should not be relied upon as a primary safety device; provide adequate air gap around the module in the back box.
Do not exceed 4.3 A on inductive or capacitive loads even though the marketing copy quotes 5 A; the 5 A figure is the resistive/LED rating and inrush from transformers or large capacitive LED drivers can trip the overload cutoff or weld relay contacts. Avoid pairing the SR-MT9041A-2R with non-dimmable electronic low-voltage transformers on Channel 2 unless the transformer is explicitly rated for relay switching. Verify the push (retractive) switch wiring polarity in the user manual before energizing.
Placement matters for wireless range: install the relay away from large metal switch plates (which attenuate the 2.4 GHz radio) and avoid mounting inside metal-clad boxes if the box isn't specifically designed for radio transparency. Where possible, place the module such that the radio antenna region (per the manufacturer datasheet mark) faces free air. Pair the device BEFORE attaching the wall switch plate to avoid radio absorption during commissioning.
