Product Overview
Introduction
Product Name |
SONOFF SwitchMan Zigbee Smart Wall Switch |
Product Model |
This device is a Zigbee-based smart wall switch, which allows for either neutral-required wire mode or no neutral-required wire mode, depending on your home's circuit setup. Used with a SONOFF Zigbee gateway, you can achieve remote control of device opening/closing, setting a schedule/timer, creating smart scenes, and other smart control methods.
Highlights
① Universal Wiring Compatibility
Supports both Neutral-Required Wire Mode and No Neutral-Required Wire Mode.
② Zigbee 3.0 Connectivity
ZBM5 is fully compatible with Sonoff Zigbee gateways and can be seamlessly integrated with Home Assistant via ZBDongle, delivering localized low-latency control for a stable and reliable whole-home smart network.
③ Detach Relay Mode
With this function enabled, you can still remotely control your smart devices through "Smart Scenes" even when the physical switch is turned off. And if the device goes offline, the physical switch instantly resumes full control.
④ Zigbee Router
When the ZBM5 is in the Neutral-Required Wire Mode, it also acts as a Zigbee router, strengthening your Zigbee mesh network by enhancing signal coverage and improving device communication. Enjoy reliable connectivity across your smart home.
⑤ Timer & Schedule
Set up custom schedules and countdown timers to automate your appliances based on your lifestyle.
⑥ Smart Scene
- Instant Setup: Activate complex routines with a single tap.
- Whole-Home Synchronization: Cross-device automation within the Sonoff ecosystem – build your personalized smart scenarios.
Applications
- Scheduled Lighting Control
Set timers (e.g., lights on at 9 AM, off at 10 PM) to reduce energy costs while enhancing the automated experience.
- Relay Isolation Mode
Physically power off lights without losing app control—solving the "offline control issue" of traditional smart bulbs.
- Home/Away Modes with Smart Lighting
When connected to household lamps, the ZBM5 works with the SONOFF Gateway + Motion Sensor to enable:
- Home Mode: Automatic lights on when you arrive
- Away Mode: Lights off when no motion is detected
- etc...

Wiring Mode Description
When the device is powered on for the first time, it will automatically enter either no neutral required mode or neutral required mode based on the actual wiring setup. Different modes have varying compatibility with loads. If you need to switch wiring methods, such as changing from neutral-required mode wiring to no neutral-required mode wiring, follow the steps below to switch the device mode:
1. Choose one of the following methods to restore the device to its factory settings:
● Press and hold any button on the device for more than 5 seconds
● Delete the device in the eWeLink app
2. After disconnecting power and reconnecting, the device's signal indicator (blue) will flash three times.
Once the above steps are completed, wait for 10 seconds before the device can function properly. Add the device to the gateway again, and it will switch to the corresponding mode based on the new wiring setup.
Differences Between Wiring Modes
1. No Neutral Required Mode:
The device functions as a Zigbee end device, and the external load has a minimum power requirement, with a minimum load of 3W. In this mode, smart lights are not supported, including but not limited to dimmable, color-changing, gradient, and lights with built-in controllers, as well as light strips.
2. Neutral Required Mode:
The device functions as a Zigbee router, enhancing the robustness and coverage of the Zigbee network in the use environment. This mode has fewer restrictions on external load, with no minimum power requirement. Smart lights are supported in this mode and can be used with the eWeLink app's "Detach Relay" function.
FAQ
1. What types of bulbs are supported, and what is the compatibility range?
The support and requirements for bulbs are as follows.
①Incandescent Bulbs:
2400W@240V MAX (per channel or total), 1000W@100V MAX (per channel or total), minimum of 3W (for no neutral required mode only).
②LED/CFL/Fluorescent Bulbs:
400W@240V MAX (per channel or total), 200W@100V MAX (per channel or total), minimum of 3W (for no neutral required mode only).
For older fluorescent tubes with starters, replace the starter with an electronic one to avoid potential switch damage.
Troubleshooting
1. Why does the light bulb light up slightly or flicker after turning off the light?
This issue only occurs in the no neutral required wiring mode and may be caused by the following two factors:
①The device is in neutral required mode, but the actual wiring is not neutral.
You can check this fault via the app reminder. In some special cases, the product's operating mode may not switch correctly. For example, if the device was previously operating in neutral required mode but the wiring is changed to no neutral required without resetting the device, it may not switch to the correct mode.
Solution: Reset the device according to the 'Switch Wiring Mode' section above.
②The external bulb has insufficient power or is incompatible.
In no neutral required mode, the minimum power requirement for external bulbs is 3W. Therefore, the connected bulb must be at least 3W. Even if the bulb power meets 3W, it does not necessarily mean that it is compatible. No neutral required mode supports most major lighting brands, but bulbs from lesser-known or knockoff brands may cause issues, such as flickering or device malfunction, due to their internal circuit design and materials. Please choose carefully.
Solution: Replace the bulb with a brand-name bulb with a power rating of ≥3W.
2. For multi-channel products, when the A channel bulb is turned on, why does the B channel bulb, which is in the off state, light up slightly or flicker?
This problem is also caused by the incompatible or poor compatibility of the bulbs used. It may be caused by the A channel bulb or the B channel bulb, and the latter is more likely.
