Multi-admin control – pair once, control from every Matter ecosystem simultaneously
Keeps your existing faceplate – no decor changes needed at the wall

Mini-format Matter retrofit modules designed to fit behind an existing UK or EU wall switch, or inside a ceiling rose. Convert any standard wired light circuit into a Matter-native smart circuit – without changing the faceplate, without proprietary apps, and without needing a single-vendor hub.

Compatible with every major Matter ecosystem out of the box: Apple Home (Siri), Google Home (Assistant), Amazon Alexa, Samsung SmartThings, and the Home Assistant Matter integration. Modules use Matter over WiFi for connectivity – no Thread border router needed.

Why Matter is worth choosing now

Matter is the new open smart-home standard backed by Apple, Google, Amazon, Samsung, and the Connectivity Standards Alliance. The practical advantage: one device works across every major platform simultaneously, without bridges, account linking, or vendor lock-in.

Specifically:

One device, multiple controllers. The same module shows up in Apple Home AND Google Home AND Alexa AND SmartThings simultaneously, not just one or another. Different family members can use different ecosystems.
Local control by default. Matter is local-first. Commands stay on your home network – no cloud round-trip, no internet dependency for basic on/off.
Standards-based, not proprietary. Future-proof: the Matter standard is owned by the CSA consortium, not any single company. Less chance of an end-of-life event killing your devices.

For comparison with a Zigbee equivalent (which requires a Zigbee hub), see our Zigbee Switch & Dimmer Modules.

Variations available

1, 2, 3 and 4 gang switching modules – on/off control for one, two, three or four independent lighting circuits from a single back box.
No-neutral and conventional wiring – both supported on most variants.

Installation requirements

UK 37mm-deep back box minimum recommended
Existing retractive or standard wall switch wired to the module’s signal input
Live (and optionally neutral) supply
2.4 GHz WiFi network for Matter-over-WiFi pairing

Safety: Always isolate the circuit at the consumer unit before working on mains wiring. UK Part P regulations may apply – use a qualified electrician if unsure.

Pairing

Install the module and power the circuit.
Open the controlling app (Apple Home, Google Home, Alexa, or SmartThings) and add a new accessory.
Scan the Matter QR code printed on the module.
The app commissions the module to your Matter network within 30-60 seconds.
Optionally share the module to additional Matter-compatible apps using each ecosystem’s standard share flow.

Frequently Asked Questions

What's included in the Matter Switch Modules range?

The Samotech Matter Switch Modules range covers compact 39 × 39 × 18 mm Matter over WiFi modules designed to fit behind any standard UK/EU light switch or inside a ceiling rose. Each module provides on/off switching, 2-way, rated 10–100W per channel, with Live-only wiring (no neutral required).

What is Matter and why does it matter?

Matter is a smart home protocol developed to unify and simplify device interoperability across different ecosystems. Built on security, reliability, and open-source collaboration, Matter lets devices from various brands work together seamlessly, whether connected via WiFi, Thread, or Ethernet. It enables a universal "language" for smart devices, faster response times, and better cross-platform consistency.

How many lighting circuits can one module control?

Switch Modules come in 1, 2, 3 and 4 gang versions, controlling one, two, three or four independent lighting circuits from a single back box. Each channel switches on/off at 230VAC, 10–100W per channel, and reports its state back to every paired Matter app.

Which platforms control the Matter Modules?

The modules integrate with all major Matter-compatible controllers: Apple Home (HomeKit), Google Home, Amazon Alexa, and Samsung SmartThings. Pair the module to whichever ecosystem you primarily use, or to multiple, since Matter supports multi-admin sharing across compatible apps.

Do the Matter Switch Modules require a hub?

Matter over WiFi modules need a Matter-compatible hub or controller, such as an Apple TV or HomePod, Google Nest Hub, an Amazon Echo with Matter support, a SmartThings Station or Hub, or Home Assistant with the Matter integration. The hub provides the local Matter controller and remote-access gateway for each module.

What back box depth do the modules need?

A 37mm deep wall box is recommended for clean installation behind a UK light switch. The compact 39 × 39 × 18 mm form factor leaves enough room for wiring connections inside a standard 37mm UK back box.

What features do the Matter Modules support?

All modules support remote control through Matter-supported apps, schedules, timers, countdowns, scenes, automations, and shared access, all with strong end-to-end security, fast response times, and the multi-admin flexibility Matter brings.
