Sonoff Smart Wall Switch ZBM5 Triple Review: A Three-Gang Zigbee Switch for No-Neutral Boxes
One unit replaces up to three switches with or without a neutral wire, though Home Assistant users flag some state-sync quirks.
The Sonoff ZBM5 Triple packs three independently controlled switches into a single Zigbee unit that can be wired with or without a neutral, making it a practical option for consolidating a crowded multi-gang box. Buyers consistently praise the easy install and quiet, responsive buttons, and many report smooth operation through Alexa, Google Home or a Zigbee hub. The recurring caveat comes from Home Assistant and zigbee2mqtt users, who note the switch's physical button state and its Zigbee-reported state can drift out of sync, plus some no-neutral installs reporting occasional hub disconnects. It suits buyers who want to replace several switches with one device and mainly drive it through the app or voice assistants rather than lean on physical button presses within a strict open-source automation setup.
- Consolidating a crowded multi-gang switch box

Who is the Sonoff Smart Wall Switch ZBM5 Triple for?
This is a three-gang Zigbee switch designed to replace up to three individual switches with a single unit, ideal for garages, hallways, or utility rooms with several light circuits in one box. It supports installation with or without a neutral wire, a useful flexibility for older homes, and requires a Zigbee hub (Sonoff's own bridge or a third-party Zigbee coordinator) to connect, integrating with Alexa, Google Home, Samsung SmartThings and Home Assistant. It does not support Apple HomeKit or Matter, so Apple-first households should look elsewhere.
What buyers love
Reviewers repeatedly highlight how easy the switch is to install and pair, along with a quiet, responsive button press from anywhere on the switch face rather than just the bottom edge. Voice control through Alexa and Google Home works reliably for most owners, and being able to consolidate three switches into one unit is called out as a practical, cost-effective way to modernize a multi-gang box. Several buyers also like that the relay can be decoupled from the physical button, useful for controlling smart bulbs without cutting power at the switch.
What to know before you buy
This switch has no energy monitoring and no overheating, overvoltage, overcurrent or overpower protection. The most notable caveat comes from Home Assistant and zigbee2mqtt users, who report the device tracks separate states for the physical button and for Zigbee reporting, which can fall out of sync if the button is pressed directly instead of controlled purely through the hub; one reviewer noted a firmware/profile update improved this. A few no-neutral installations report the switch periodically dropping off the Zigbee hub and needing re-pairing. It is also not built to fit standard multi-gang wall plates, so replacing only some switches in a shared box may require a full plate swap. These points track with its below-average aggregate rating relative to Sonoff's Matter-based M5 line.
Is the Sonoff Smart Wall Switch ZBM5 Triple worth it?
For anyone consolidating a busy three-switch box and wanting no-neutral flexibility with app or voice control, this switch delivers strong practical value at a reasonable price. Buyers running a strict Home Assistant/zigbee2mqtt setup that relies on physical button presses for local automation should weigh the reported state-sync quirks first, since that is where the mixed feedback concentrates.
Frequently asked questions
Does the Sonoff ZBM5 Triple require a neutral wire?
No, it can be installed with or without a neutral wire, though a no-neutral installation runs as a Zigbee end device rather than a router.
Can one ZBM5 Triple replace three separate light switches?
Yes, it packs three independently controlled switches into a single unit, useful for consolidating a multi-gang box.
Does it work with Apple HomeKit or Matter?
No, this model does not support Apple HomeKit or Matter. It integrates with Alexa, Google Home, Samsung SmartThings, Home Assistant and IFTTT through a Zigbee hub.
Do I need a separate hub to use this switch?
Yes, it requires a Zigbee hub, such as Sonoff's own Zigbee bridge or another Zigbee coordinator, to connect to your smart home.
Does it work well with Home Assistant and zigbee2mqtt?
It can work, but some Home Assistant/zigbee2mqtt users report the switch's physical button state and its reported Zigbee state can fall out of sync, particularly if the button is pressed directly rather than controlled through the hub.
Does the switch have energy monitoring or overload protection?
No, this model does not include energy monitoring or overheating, overvoltage, overcurrent or overpower protection.
