Before you buy
Lighting on/off control only. For compatible lighting circuits only, with on/off switching. Do not connect heavy-load appliances or inductive/motor loads such as fans or pumps. This is not a dimmer or fan-speed controller. LED-driver compatibility, startup/inrush current and the permitted lighting load must be checked for this exact model before installation; an amp marking is not a universal LED wattage allowance.

Before you install
The product label marks input and output 16 A max. The label alone does not establish a per-channel allowance, combined-load limit or tested LED wattage limit. Confirm the permitted lighting load and LED-driver startup/inrush current for this exact model before installation; do not multiply the marked current by the number of outputs.
Neutral is required. Use a qualified electrician to verify the load, switch compatibility, dimensions, enclosure space and wiring for the exact unit. The separate source-label wiring reference applies only when the supplied unit and terminal labels match exactly. Decorative retrofit scenes are not wiring guides. Do not substitute a diagram from another gang count or unmatched model.
Practical installation and everyday use
App OFF and wall-switch control are not safe isolation
App OFF is a control command, not electrical isolation. The wall switch connects to the module's control inputs; it must not be treated as an independent fail-safe mechanical bypass. For electrical work, isolate the circuit at the appropriate isolating device and have a qualified electrician verify absence of voltage.
Review the connection requirements and lighting restrictions before ordering. Exact dimensions and permitted LED-driver loads must be confirmed for the supplied model.
What affects response time?
Response varies with radio signal, router or gateway connection, internet/cloud services when used, and LED-driver start-up. Wall-switch and app commands use different paths. No fixed millisecond delay, zero-delay performance, or guaranteed offline behavior is promised.
Plan the installation
Neutral is required. Check the actual module, clips, leads and wiring against the available box clearance. A 6- or 8-module faceplate does not guarantee fit. Confirm switch type and compatible lighting load. Installation must be by a qualified electrician with power isolated and verified dead; this checklist is not a wiring or scale drawing.
Choose the right channel count
1, 2, 3 and 4 gang mean that many separately switched lighting channels, not pack quantity. More channels do not establish a safe combined load. Every connected lighting group must meet the exact model's verified limits.
1-gang source-label wiring reference
1-gang source-label wiring reference: supply live to L-in terminal 2, neutral to N-in terminal 4; light live to L-out terminal 1 and neutral to N-out terminal 3; optional single-pole switch between terminals 5 N-in and 6 S. Match the exact label. Qualified electrician only; isolate and verify absence of voltage. Diagram orientation is label upright, terminals left to right. Dots indicate joined conductors; bridges indicate crossings without connection. Colors show function, not installed wire colors. Connection reference only: protective earthing, circuit protection and enclosure wiring are not shown. These must be retained or provided as required for the installation. Isolate the supply and verify absence of voltage; installation by a qualified electrician. Match the exact supplied label.
1-gang numbered terminal reference
1-gang numbered terminal reference, viewed with the label upright, left to right. Supply live: terminal 2 L-in; supply neutral: terminal 4 N-in. Light live: terminal 1 L-out; light neutral: terminal 3 N-out. Optional single-pole switch between terminal 5 N-in and terminal 6 S. Exact supplied label must match; qualified electrician only.
1 year warranty against any manufacturing defects.
FAQs
What does 1-gang mean for this module?
It identifies one switched output for one compatible lighting group. Gang count is not a pack quantity and does not multiply the current rating. The connected lighting and wiring must be suitable for this model.
Which app does it work with?
It works with OKOS Smart. The Wi-Fi version connects through a compatible 2.4 GHz router.
Do I need a hub, and will it work on 5 GHz Wi-Fi?
A Zigbee gateway is not required. The module uses 2.4 GHz Wi-Fi, not a 5 GHz-only network. Check the router setup and signal at the installation position.
Can I keep using my wall switch?
External wall-switch connections support a compatible manual-control installation. Have an electrician confirm the switch type, wiring and available space. The exact switch operating mode must be checked; do not assume every toggle, rocker, push-button or two-way arrangement is supported.
Does it need a neutral wire, and will it fit my switchboard?
Yes, neutral is required. Have a qualified electrician check the exact module dimensions, enclosure depth, wiring space and switch compatibility before ordering or installation. Universal switchboard fit is not promised. Use the separate source-label wiring reference only if the exact supplied unit and terminal labels match. Connection reference only: protective earthing, circuit protection and enclosure wiring are not shown. These must be retained or provided as required for the installation. Isolate the supply and verify absence of voltage; installation by a qualified electrician. Match the exact supplied label.
Can I use timers, scenes and voice control?
OKOS Smart timers and scenes are supported for this Wi-Fi model. Alexa and Google Assistant control require compatible devices, supported account linking and internet access. Scene actions depend on the other devices and integrations used.
Can it dim lights or control fans and appliances?
For compatible lighting circuits only, with on/off switching. Do not connect heavy-load appliances or inductive/motor loads such as fans or pumps. This is not a dimmer or fan-speed controller. LED-driver compatibility, startup/inrush current and the permitted lighting load must be checked for this exact model before installation; an amp marking is not a universal LED wattage allowance.
Can I treat the 16 A marking as a universal load limit?
The product label marks input and output 16 A max. The label alone does not establish a per-channel allowance, combined-load limit or tested LED wattage limit. Confirm the permitted lighting load and LED-driver startup/inrush current for this exact model before installation; do not multiply the marked current by the number of outputs.
Which exact model is this listing for?
This listing is for the OKOS 1-gang Wi-Fi module, model OK-02W. It is not the Zigbee version. Choose the gang count and wireless version required for your installation.
