Ασύρματος διακόπτης τοίχου Sonoff ZBM5-3C-86W 3 καναλιών Zigbee, 3πλός, χωνευτός

The Sonoff ZBM5-3C-86W is a flush-mount Zigbee touch wall switch with three independent channels, allowing control of up to three lighting circuits or loads. Designed for installations with or without a neutral wire, it integrates with the eWeLink app and compatible SONOFF Zigbee gateways for remote control, voice control via Alexa or Google Home, and integration with open-source platforms such as Zigbee2MQTT and ZHA. The switch supports scheduling, smart scenes, automations and a detach relay function that keeps smart bulbs powered when the physical switch is turned off.

Advantages

The model supports both neutral and no-neutral installations, simplifying upgrades in older homes while remaining compatible with newer wiring. It uses Zigbee 3.0 for reliable local mesh networking and works with SONOFF gateways (iHost, NSPanel Pro, ZBBridge-U/P, ZBDongle-E/-P) and third-party open-source systems. Three independent touch channels, low minimum load operation (3 W without neutral), and a detach relay feature give flexible control for mixed lighting setups and smart bulbs.

Suitable for

• Flush-mounted residential lighting control
• Homes with or without a neutral wire
• Integration into Zigbee-based smart home systems (eWeLink, Zigbee2MQTT, ZHA)
• Voice control setups with Alexa or Google Home

How to use

Install the Sonoff ZBM5-3C-86W into a standard flush-mount box following local wiring rules and the included user manual. Connect live, load and neutral wires where applicable; the switch supports operation without a neutral wire but requires attention to the minimum load specification. Pair the switch to a compatible SONOFF Zigbee gateway or Zigbee coordinator, then add it in the eWeLink app to set schedules, scenes and automations. Use touch control on the panel for local switching or voice commands via a linked Alexa or Google Home account for hands-free operation.

Recommendations

For stable Zigbee performance, place the switch within range of a Zigbee gateway or mesh devices and avoid strong Wi‑Fi or other RF interference. Observe the minimum load when installing without a neutral wire, and verify compatibility of connected bulbs with the detach relay mode before relying on always-on power to smart bulbs.
