⚡ Best Matter In-Wall On/Off Relay Modules

12 behind-the-switch relays ranked by a firmware engineer who ships Matter-certified products: native Matter picks from Shelly, SONOFF and SwitchBot, plus proven Zigbee relays you can bridge into Matter, with real load ratings, honest verdicts and direct Amazon links.

✅ 12 Relay Modules Reviewed ✅ Verified Amazon ASINs ✅ Native vs Bridged Explained ✅ Honest Pros & Cons

An in-wall relay module is the least visible and most flexible way to make lighting smart. It hides in the wall box behind the switch you already have, keeps that switch working, and adds remote control, schedules and automations. Choose one that speaks Matter and the same module works with Apple Home, Google Home, Alexa, SmartThings and Home Assistant, controlled over your local network instead of a vendor’s cloud. You keep your favorite switch plates, guests keep the switch they know, and you can move ecosystems later without rewiring.

The trouble is that “Matter relay” covers very different hardware. Some modules are natively Matter-certified over Wi-Fi, some are Zigbee relays that reach Matter only through a bridge, some switch mains loads while others give you an isolated dry contact for garage doors and boilers, and only a few work without a neutral wire. This guide ranks 12 in-wall on/off relay modules in two clearly labeled groups (nine native Matter modules and three Zigbee relays you can bridge) on what matters behind the wall: load rating, size, metering, dry contact support, neutral requirements and how cleanly they join a Matter fabric.

💡 Reality check before you buy: These modules connect to mains voltage. If you aren’t confident working inside a live wall box, hire an electrician and check your local code. Almost every native Matter relay here runs Matter over 2.4GHz Wi-Fi and needs a neutral wire in the box; older US switch boxes often have none, and the only no-neutral pick in this guide is a Zigbee relay that needs a hub and a bridge. Check the voltage and certification of the exact listing: several popular relays are designed to EU 230V standards, while Shelly sells separate UL-listed Gen4 versions for North America. Finally, Matter’s on/off control is universal, but power metering is not: many controllers still show only a switch, so you may need the maker’s app or Home Assistant to see energy data.

🔍 What to Look for in a Matter In-Wall Relay

🔗

Native vs Bridged Matter

A native Matter relay pairs straight to your controller by scanning its QR code. A bridged relay runs Zigbee and appears in Matter only through a hub that re-exposes it, such as an Aqara hub, Homey Pro or Home Assistant with a Matter bridge add-on.

🔌

Neutral Wire & Wall Box Size

Open the box first. Most relays need line and neutral to power their radio. Measure the depth behind the switch too: a mini module (about 40 x 33 mm) fits where a full-size relay will fight the switch and the wire nuts.

⚡

Load Rating & Certification

8A is plenty for LED lighting; motors, heaters and pumps want 15A to 16A with headroom. In North America, prefer UL-listed versions; many relays are built to EU 230V standards and only carry CE marks.

🚪

Wet vs Dry Contact

A wet-contact relay passes mains power through to the light. A dry contact is an isolated switch closure for garage door openers, gate controllers, doorbells and boiler call-for-heat terminals. Pick a module that supports the mode you need.

📊

Metering & Switch Input

“PM” models measure power, which helps catch a stuck pump or a heater left on. Also check the switch input: support for toggle and momentary switches, 3-way setups and “detached” mode lets the wall switch trigger scenes instead of cutting power.

🏆 Detailed Reviews: All 12 Matter In-Wall Relay Modules

Picks 1 to 9 are natively Matter-certified relays. Picks 10 to 12 are proven Zigbee relays that join Matter through a bridge.

Shelly 1PM Gen4 in-wall Matter and Zigbee relay switch with power metering

Shelly has been the default retrofit relay for years, and the 1PM Gen4 is the version that finally makes it a first-class Matter device. It switches a single circuit up to 16A, measures power on that circuit, and pairs straight to Apple Home, Google Home, Alexa, SmartThings or Home Assistant with no hub required. It is also a multiprotocol radio: you choose Wi-Fi with Matter or Zigbee 3.0 mode before pairing, which future-proofs it if you later move to a Zigbee setup. The switch input handles toggle and momentary (push-button) switches and 2-way wiring, it doubles as a Bluetooth gateway for Shelly BLU sensors, and it keeps Shelly’s local web UI, scripting and MQTT, so Home Assistant users get instant local control. With more than 550 ratings averaging 4.6 stars it is also the most proven Matter relay in this guide. It is a wet-contact relay only (no dry contact), and North American buyers can choose the UL-listed 1PM Gen4 instead.

✅ Pros
  • 16A with power metering
  • Matter or Zigbee mode in one device
  • Local web UI, scripts and MQTT
  • Large, positive review base
❌ Cons
  • Needs neutral wire
  • No dry contact (use the Shelly 1)
  • Energy data may not show in every Matter app
🎯 Verdict: The Matter in-wall relay to buy for most lights and appliances. Load rating, metering, local control and track record are all a step above the rest.

SONOFF MINIR4M Matter Wi-Fi in-wall smart relay module

The MINIR4M is the Matter version of SONOFF’s “MINI Extreme” relay, and it is the cheapest way in this guide to put a Matter-certified relay behind a switch. At 39.5 x 33 x 16.8 mm it is roughly 40% smaller than the older MINIR2, so it slips into crowded single-gang boxes. It switches 10A, pairs over Bluetooth into your Matter controller, and accepts rocker, momentary, SPDT and even dry-contact sensor inputs on its switch terminals. The standout feature is detach relay mode: the wall switch can send a scene trigger without cutting power, which is perfect for keeping smart bulbs powered while the switch still “works”. Power-on delay after an outage is configurable in eWeLink. It has no power metering, and the listing rates it for 240V; it needs a neutral.

✅ Pros
  • Matter-certified at a budget price
  • Very small, easy to fit
  • Detach relay for smart bulbs
  • Works with many switch types
❌ Cons
  • 10A ceiling, no metering
  • No eWeLink-Remote BLE control
  • Not UL-listed per the listing
🎯 Verdict: The best-value Matter relay for lighting circuits. Buy several and convert a whole floor of switches without a hub.

🇺🇸 BEST UL-LISTED & DRY CONTACT · ⭐ 4.6/5

3. Shelly 1 Gen4 UL Smart Relay Switch

Matter + Zigbee + Wi-Fi · 15A · UL certified · dry or wet contact · Bluetooth gateway
Buy Here →
Shelly 1 Gen4 UL Matter relay switch with dry contact for wall boxes

The plain Shelly 1 has always been the relay of choice for garage doors and gate openers because its contacts can be dry (isolated from mains). The Gen4 UL version keeps that trick, adds native Matter alongside Zigbee and Wi-Fi, and carries a UL certification with a 15A single channel, which matters for North American installs and inspections. Use it wet behind a light switch or dry across the push-button terminals of an opener. It has no power metering, and the UL listing is new with only a handful of ratings, though the hardware matches the long-proven global model.

✅ Pros: UL certified; dry or wet contact; 15A; Matter and Zigbee in one module.
❌ Cons: No metering; few reviews on the UL listing so far; needs neutral.
🎯 Verdict: The pick for North American homes that want a listed device, or for any Matter garage door opener retrofit.

Matter + Zigbee + Wi-Fi · 8A · dry contacts · 8 MB memory · mini size
Buy Here →
Shelly 1 Mini Gen4 compact Matter and Zigbee relay switch

When the wall box is already stuffed with wire nuts, the 1 Mini Gen4 is the Shelly that fits. It shrinks the relay to a small square while keeping the Gen4 radio with Matter, Zigbee and Wi-Fi, an upgraded processor with 8 MB of memory, and dry-contact support. The trade-off is an 8A rating, which is plenty for LED lighting circuits and small appliances but not for heaters or big motors. With more than 800 ratings at 4.5 stars, it is one of the most reviewed Matter relays on Amazon.

✅ Pros: Fits crowded boxes; dry contacts; Matter or Zigbee; big review base.
❌ Cons: 8A limit; no metering; smaller terminals take thinner wire.
🎯 Verdict: The Shelly to buy for lighting behind shallow or overcrowded switch boxes.

Shelly 1PM Mini Gen4 compact Matter relay with power metering

The 1PM Mini Gen4 is the mini Shelly with a power meter inside. You get the same small footprint and 8A rating as the 1 Mini, plus real-time power and energy readings, which is useful for spotting a bathroom fan left running or tracking what a lighting circuit costs. Because it meters, it is wet-contact only. Matter, Zigbee and Wi-Fi are all on board (pick the mode before pairing), and it carries 440+ ratings at 4.6 stars. If you are converting several rooms, the 2-pack listing is the same device.

✅ Pros: Metering in a mini body; strong ratings; Matter or Zigbee.
❌ Cons: 8A limit; no dry contact; needs neutral.
🎯 Verdict: The best small relay when you want to see what each lighting circuit is using.

Buy Here →
Shelly 2PM Gen4 two-channel Matter relay switch with power metering

A double-gang box with a light and a fan on two switches needs two relays, or one 2PM Gen4. It drives two independent channels (the listing quotes up to 16A per channel) with per-channel power metering, and it can switch to cover mode for bi-directional motors such as roller shutters and blinds, where it calibrates travel and exposes position. Like the other Gen4 Shellys it speaks Matter, Zigbee and Wi-Fi and works as a Bluetooth gateway. It has 800+ ratings at 4.6 stars. North American buyers can pick the UL-listed 2PM Gen4.

✅ Pros: Two metered channels; shutter mode; Matter or Zigbee; proven.
❌ Cons: Larger body; both channels share one feed; no dry contact.
🎯 Verdict: The one-module answer for two-gang boxes and motorized shades on Matter.

🟠 BEST FOR SWITCHBOT HOMES · ⭐ 4.4/5

7. SwitchBot Relay Switch 1PM

Matter over Wi-Fi · 16A · energy monitoring · Bluetooth repeater · bridges 2 BLE devices to Matter
Buy Here →
SwitchBot Relay Switch 1PM Matter Wi-Fi relay with energy monitoring

SwitchBot’s Relay Switch 1PM is Matter-certified over Wi-Fi, switches up to 16A with energy monitoring, and adds something no other relay here does: its built-in Bluetooth repeater extends up to ten SwitchBot Bluetooth devices and can expose two of them to Matter, so a SwitchBot Bot or Curtain can show up in Apple Home without a separate hub. The “Hub Required” in the Amazon title refers to a Matter controller (a smart speaker or hub from Apple, Google, Amazon or Samsung), not a SwitchBot hub. Setup starts in the SwitchBot app, after which you switch it to Matter pairing mode. It has 270+ ratings at 4.5 stars and needs a neutral.

✅ Pros: 16A with metering; doubles as a BLE-to-Matter bridge; polished app.
❌ Cons: Account and app needed for setup; less open than Shelly for local control.
🎯 Verdict: The smart buy if you already own SwitchBot Bluetooth gadgets you want in Matter.

SwitchBot Relay Switch 1 Matter relay module with dry contact mode

The Relay Switch 1 is the 1PM’s sibling built for dry-contact jobs: doorbells, garage openers, gate controllers and low-voltage circuits where you want an isolated switch closure rather than mains on the output. It keeps Matter over Wi-Fi, the Bluetooth repeater and SwitchBot’s scenes, and at about 42 x 37 x 16 mm it fits most boxes. Choose the 1PM above for metered mains loads. The Amazon page is a shared listing for the whole Relay family, so make sure “Relay 1 (1 pack)” is selected before you check out.

✅ Pros: Dry contact mode; native Matter; BLE repeater; small.
❌ Cons: Shared variant listing is easy to mis-order; app account required.
🎯 Verdict: A tidy Matter dry-contact relay for doorbells and openers in a SwitchBot home.

9. SONOFF MINI-D Matter Smart Switch

Matter over Wi-Fi · dry contact output (NO and NC) · AC or DC input · 1,000+ ratings
Buy Here →
SONOFF MINI-D Matter Wi-Fi smart switch with dry contact output

The MINI-D is a different animal: a Matter relay whose output is a pure dry contact with both normally open and normally closed terminals. It is built to trigger boilers, garage door openers and access-control systems, and it can directly drive small DC motors and solenoid valves up to about 8W. Its supply input accepts AC or DC, which makes it handy inside low-voltage enclosures. Read the listing carefully: the outputs are not for switching AC lighting, so it is not a light-switch relay. For contact closures it is excellent, with 1,000+ ratings at 4.7 stars.

✅ Pros: NO and NC dry contacts; AC or DC powered; highly rated.
❌ Cons: Can’t switch mains lighting loads; low DC output power.
🎯 Verdict: The best Matter dry-contact module for openers, gates and heating call-for-heat wiring.

🌉 Bridged Picks: Zigbee Relays That Join Matter Through a Hub

The last three are not Matter devices on their own. They pair to a Zigbee coordinator, and a bridge then exposes them to Apple Home, Google Home, Alexa or SmartThings as Matter switches. Aqara’s Matter-capable hubs do this for Aqara devices; for any brand, a Homey Pro with its Matter Bridge app or Home Assistant (ZHA or Zigbee2MQTT) with a Matter bridge add-on works. Zigbee relays are mesh routers, use no Wi-Fi, and include the only no-neutral option in this guide.

SONOFF ZBMINIR2 Zigbee 3.0 in-wall smart relay switch

If your home runs Zigbee, the ZBMINIR2 is the most popular in-wall relay for it, with 1,400+ ratings at 4.6 stars. It is tiny, acts as a Zigbee router that strengthens your mesh, supports rocker and push-button switches, and works with SmartThings, Hubitat, Home Assistant and Echo devices with a built-in Zigbee hub. Bridge it from Home Assistant or Homey and it appears in Matter as a regular on/off switch. Note that the Amazon title says neutral required while some bullet text is copied from the no-neutral model; trust the title. 2-pack and 4-pack options are on the same listing.

✅ Pros: Huge review base; Zigbee router; no Wi-Fi load; tiny.
❌ Cons: Needs a Zigbee hub plus a Matter bridge; confusing listing copy.
🎯 Verdict: The safest Zigbee relay to bridge into Matter from Home Assistant or Homey.

11. SONOFF ZBMINIL2 Zigbee Smart Switch (4-Pack)

Zigbee 3.0 · no neutral required · 6A · 39.5 x 32 x 18.4 mm · 2-way control
Buy Here →
SONOFF ZBMINIL2 no-neutral Zigbee in-wall relay module

Plenty of older homes have only line and switched-load wires at the switch. The ZBMINIL2 is built for exactly that: it needs no neutral, fits a 39.5 x 32 x 18.4 mm space, supports 2-way staircase setups, and is rated 6A for lighting. Because no-neutral devices power themselves by trickling current through the bulb, it is low-power Zigbee only, so you reach Matter through a Zigbee hub and bridge. This listing is a 4-pack (794 ratings, 4.4 stars). Expect a minimum-load requirement: tiny LED loads can glow or flicker when off, so pair it with a decent wattage or a bypass capacitor if needed.

✅ Pros: Works without neutral; compact; 2-way control; four in the box.
❌ Cons: 6A lighting only; low-load LED flicker risk; hub plus bridge needed.
🎯 Verdict: The practical way to get no-neutral switch boxes into a Matter home today.

12. Aqara Dual Relay Module T2

Zigbee 3.0 · 2 channels · 10A max · metering · dry contact + interlock · DIN rail option
Buy Here →
Aqara Dual Relay Module T2 Zigbee relay with Matter over bridge

Aqara’s Dual Relay Module T2 is the most flexible relay in this guide. It controls two circuits, meters energy, offers a dry-contact mode with pulse or on/off switching, and an interlock mode for tubular shade motors. It can live behind a switch, near the light, or on a DIN rail in a panel, and the module supports a 10A maximum. It is Zigbee 3.0, so Matter comes through a Matter-capable Aqara hub (Aqara names the M2, M1S Gen 2, E1 and Camera Hub G3), which exposes it to Apple Home, Google Home and Alexa as “Matter over bridge”. The US Amazon listing is thin (about a dozen ratings and a short title), so confirm the seller and model DCM-K01 before buying.

✅ Pros: Two channels; dry contact and interlock; DIN mount; metering.
❌ Cons: Aqara hub required for Matter; 10A total; sparse US listing.
🎯 Verdict: The pick for Aqara-hub homes that need two circuits, motors or a panel-mounted relay.

❓ Frequently Asked Questions

Do Matter in-wall relays need a neutral wire?

Almost all native Matter relays do, because a Wi-Fi radio needs steady power that only line plus neutral can provide. Check your box: if you see a bundle of white wires tied together at the back, you have neutral. If not, the realistic options are a no-neutral Zigbee relay such as the SONOFF ZBMINIL2 bridged into Matter, or running a neutral with an electrician’s help.

Wi-Fi, Thread or Zigbee: which relay is best for Matter?

Today almost every in-wall Matter relay is Matter over Wi-Fi, which needs no extra radio but adds devices to your 2.4GHz network. Thread relays remain rare. Zigbee relays are excellent mesh routers but need a hub and a Matter bridge. The Shelly Gen4 line hedges the bet: each module can run in Matter (Wi-Fi) mode or Zigbee mode, chosen before pairing. For a handful of switches Wi-Fi Matter is simplest; for dozens, a solid mesh plus a bridge can be more robust.

Can I keep my existing wall switch and 3-way wiring?

Yes, that is the main appeal. The wall switch connects to the relay’s switch input (often labeled SW or S1), and the relay drives the load. Most modules here accept both toggle and momentary switches, and Shelly and SONOFF support 2-way configurations. With “detached” mode the switch only sends an event, which lets you keep smart bulbs permanently powered while the switch triggers a Matter scene.

What is the difference between a wet and a dry contact relay?

A wet-contact relay outputs the same mains voltage that powers it, which is what you want for lights and appliances. A dry contact is an isolated switch, like pressing a button, used for garage door openers, gate controllers, doorbells and boiler thermostat terminals. Shelly 1 Gen4, Shelly 1 Mini Gen4, SwitchBot Relay Switch 1, SONOFF MINI-D and the Aqara T2 offer dry contact modes; metering “PM” models are wet-contact only.

Do Matter relays keep working when the internet goes down?

Yes. The physical switch always works because it is wired to the relay, and Matter control runs locally between your controller and the device over your home network, so automations on a local hub (Apple home hub, Home Assistant, SmartThings) keep running. You lose remote access from outside the house and any cloud-only features of the maker’s app until the connection returns.
