Sonoff M5 Matter Wall Switch (US, Single) Review: A Matter Switch for US Wall Boxes
One rocker rated 10 A and 2200 W in a 120 x 74 mm US format plate, with native Matter and no hub required.
This is the US-format version of Sonoff's M5 single switch: a 120 x 74 mm plate sized for North American wall boxes, switching one circuit at up to 10 A and 2200 W on 100-240 V AC. Matter support is native over Wi-Fi, so it commissions straight into Apple Home, Google Home, Alexa or SmartThings without a hub, and Home Assistant and IFTTT work too. It requires a neutral wire, which most US boxes have, and its gaps are the same as the rest of the range: no energy monitoring and no documented safety protections.

Who is the M5 US single for?
It suits a North American home that wants smart lighting without smart bulbs and without a hub. Replacing the switch means every bulb on the circuit becomes controllable, including plain LED and incandescent fittings, and the switch still works by hand for anyone who ignores the app. Native Matter is the reason to pick it over a cheaper Wi-Fi switch: the same device works with Apple Home, Google Home, Alexa and SmartThings, so it does not lock the installation to one ecosystem, and Home Assistant and IFTTT are available for scripted setups.
What it handles
One rocker switching up to 2200 W at 10 A on 100-240 V AC, a comfortable rating for any lighting circuit and enough for heavier fittings too. Power-off memory decides the state when power returns after an outage. The status LED is adjustable, so it can be dimmed or switched off in a bedroom, and automations run through whichever platform you connect it to. The plate measures 120 x 74 mm with a depth of 41.5 mm.
What to know before you buy
A neutral wire is required, which is standard in most modern US installations but not guaranteed in older ones. None of the four safety protections (overheating, overvoltage, overcurrent, overpower) are listed for this model, which is worth weighing against switches that document them. There is no energy monitoring. Wi-Fi is 2.4 GHz only, and every Wi-Fi switch takes a slot on the router, so a whole-house rollout is better served by a Zigbee system. Wireless switch mode, the decoupled scene-button behaviour, is not documented. Depth is 41.5 mm, so confirm the box has room. Warranty is one year.
Is the M5 US single worth it?
It is cheap, well rated at 10 A, and future-proofed by native Matter, which is an unusual combination at this price. The missing protections and metering are the trade. For one or a few switches in a US home, on any ecosystem, it is one of the easiest ways to get smart lighting that everyone in the house can still operate normally.
