Interruttore a parete smart Meross MSS815MA-UN — Wi‑Fi, compatibile Matter

Meross MSS815MA-UN is a compact Wi‑Fi smart wall switch designed for in‑wall installation behind an existing mechanical switch. It adds remote control, scheduling, automation and energy monitoring to conventional lighting circuits while remaining compatible with Matter and major smart home ecosystems. The module fits standard ⌀60 mm installation boxes and requires a neutral conductor and a 2.4 GHz Wi‑Fi network.

Advantages

The device offers Matter compatibility for broad ecosystem interoperability and supports Apple HomeKit, Google Home, Amazon Alexa, Home Assistant and the Meross app. Its small dimensions (38 x 42 x 19 mm) allow discreet installation behind many types of single‑pole switches. Local communication and stable Wi‑Fi connectivity provide fast responses and improved privacy. The unit is built from flame‑retardant PC with copper contacts and supports load monitoring in the Meross app.

Suitable for

• Retrofitting conventional single‑pole wall switches to enable remote control
• Homes and apartments with standard ⌀60 mm installation boxes
• Smart home setups using Matter, HomeKit, Google Home, Alexa or Home Assistant
• Users who want basic energy consumption monitoring for lighting

How to use

Install the Meross MSS815MA-UN behind an existing single‑pole switch inside a standard ⌀60 mm installation box. Ensure the circuit is powered off before installation and that a neutral conductor is available. Restore power, connect the device to the home 2.4 GHz Wi‑Fi network using the Meross app (or supported platform), then add it to your preferred ecosystem via Matter or the native integrations. Once configured, control the connected light remotely, create schedules and scenes, and view consumption data in the app.

Recommendations

Use only in installations with an available neutral wire and a stable 2.4 GHz Wi‑Fi network. Do not exceed the specified load limits: 10 A total, with incandescent lamps up to 400 W and LED/CFL loads up to 150 W. For safe installation, switch off power at the breaker and follow local electrical codes or consult a qualified electrician.
