SONOFF ZBM5-1C-86W Zigbee Smart Wall Switch
Introduction
This device is a Zigbee-based smart wall switch, which allows for either neutral-required mode or no neutral-required mode wiring, 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.

WARNING
Please install and maintain the device by a professional electrician. To avoid electric shock hazards, do not operate any connection or contact the terminal connector while the device is powered on!
Installation
- Wiring instructions
To ensure the safety of your electrical installation, it’s essential either a Miniature Circuit Breaker (MCB) or a Residual Current operated Cicuit-breaker with Integral Overcurrentprotection(RCBO) with an electrical rating of 10A has been installed before the ZBM5 1C-86W, ZBM5-2C-86W, ZBM5-3C-86W.
No neutral required mode wiring：
Neutral required mode wiring：
- Choose no neutral required mode or neutral required mode according to your home’s wiring.
- In no neutral required mode: the minimum supported load is 3W, and this device does not support other types of inductive loads such as fans. Make sure all wires are connected correctly.
Instructions for wiring symbols
Install the device into the mounting box
- Tighten the power module to the mounting box with screws.
- Hook the switch module’s latch into the upper groove of the metal frame.
- Press downward to fix the switch module inplace, it will automatically align with the pin positions.
- Note: When the wall-mounting box is made of plastic and the size is small, the protective cover can be omitted.
Power on
- After powering on, the device will enter the pairing mode by default during the first use and the LED signal indicator will “flash slowly”.
- When the device is powered up for the first time, the current wiring mode needs to be determined based on the wiring method, and you may need to wait for about 10 seconds before entering the normal operating state.
The device will exit the pairing mode if you do not operate it within 3 minutes. When you want to enter the pairing mode again, long-press any button on the device for 5 seconds until the signal light “flashes slowly” and releases.
Add Device
Factory Reset
- Trigger conditions (any one condition met).
- Press and hold the device button for 5 seconds.
- Delete the device on eWeLink
Switch Wiring Mode
- 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:
- 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
- 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 No Neutral Required and Neutral End Device Required Modes
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.
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.
Troubleshooting Guide and FAQs
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:
- The 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. - The 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.
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.
What types of bulbs are supported, and what is the compatibility range?
The support and requirements for bulbs are as follows.
Incandescent Bulbs:
2400W@240V MAX (per channel or total), 1000W@100V MAX (per channel or total), minimum of3W (for no neutral required mode only).
LED/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.
