You come home in the evening, the shopping bags cutting into your fingers, and while trying to switch on the light with your elbow, you notice: Why still so complicated? Imagine your light responding to you – automatically, via app, by voice, or simply very smartly. The SONOFF touch sensor makes exactly that possible: It replaces your old light switch and brings you modern control without having to chisel into walls or lay new cables. And the best part? You keep full control. Even offline. Even manually. Sounds like a real upgrade for your everyday life.
You want to make your home smart but without chiselling into walls, pulling new cables, or expensive installations? Then the SONOFF M5-2C-86W is just right for you. This elegant wall switch replaces your classic light switch and brings modern smart home functions directly into your existing electrical installation. And the best part: It works not only via Wi-Fi but also supports the new Matter standard – making it compatible with almost all major smart home platforms. Whether you want to control your light via app, with voice commands via Alexa or Siri, or automate it directly via Home Assistant: the M5-Matter makes it possible. And thanks to the built-in relay, manual operation is always maintained, even if the Wi-Fi fails.
Connection & control
The switch can be integrated directly into Apple Home, Google Home, Amazon Alexa, and Home Assistant via Matter – without additional apps or cloud services. A Matter-capable hub or a Thread Border Router (e.g., HomePod mini, Google Nest Hub, or Home Assistant SkyConnect) is required. Alternatively, the eWeLink app offers comprehensive functions such as timers, schedules, scenes, group control, and LED configuration. The connection is via stable 2.4 GHz Wi-Fi. Voice control via Alexa, Google Assistant, or Siri is also possible.
Design, material & installation
The M5-2C-86W fits standard flush-mounted boxes with an 86 mm format. It can also be mounted in German 68 mm boxes with slight modifications. The front is made of high-quality plastic with a matte surface. Modern, discreet, and easy to maintain. Operation is via a classic push button with pleasant feedback. Additionally, a blue LED indicates the Wi-Fi status, and an orange LED per button visualises the switching state. These LEDs can be individually configured in the eWeLink app: you can adjust the brightness or switch them off completely. Ideal for bedrooms or dark rooms.
Offline capability & emergency operation
Thanks to the integrated relay, the switch works even without Wi-Fi or cloud. Manual operation via the button remains available at all times. Light on/off always works. This ensures safety and comfort, even during network failures or router problems.
Further functions
Timers & schedules for automated processes, smart scenes for complex automations, group control for central management of multiple devices, device sharing for family members, and LED configuration for visual feedback.
Sonoff is appreciated by many users as an affordable and versatile manufacturer of smart home devices. Particularly praised are the easy setup, good compatibility with systems like Home Assistant, and the possibility of local use without cloud dependency. Occasionally, the quality of individual sensors, such as the SNZB-06P presence detector, and the workmanship of some devices are criticised. Overall, Sonoff is considered a solid choice for DIY enthusiasts and cost-conscious users.
