Two lighting groups, smart control and familiar wall switches
FS-02HW is a compact two-channel Wi-Fi on/off module. It adds phone control to two compatible lighting groups while allowing suitable wired wall switches to remain in use. It can be concealed in an appropriate switch or junction enclosure, so smart control does not have to mean replacing the visible switches.
This listing is for the model marked 10A Max, with AC 100–240 V supply and 2.4 GHz Wi-Fi. The maximum is a limit for the module, not a separate 10 A allowance for each channel.
Direct 2.4 GHz Wi-Fi
Connects to the router without a Zigbee hub. Check Wi-Fi coverage at the actual installation position.
Smart Life / Tuya Smart
Switch either channel from the app after pairing. Remote access depends on the module's power, network and internet services.
Two channels and wall inputs
Two on/off outputs and external-switch inputs let an electrician combine phone control with compatible wall switches.
Schedules and countdowns
Arrange suitable lighting hours or a delayed switching action using the timing controls available in the device's app panel.
Choose how you control the lights
Control the two outputs independently: for example, keep the room's main lights separate from a second decorative lighting group. Give each channel a clear name so that app actions and voice commands are easier to recognize.
The S1 and S2 inputs are for compatible wired switches. They are not extra load outputs. The supplier illustrations show different wall-switch behaviours, including rocker and self-reset options; the installer must match the actual switch and available device setting. Do not assume that every electronic switch or dimmer is compatible.
Voice, groups and family access
The supplied product material supports Amazon Alexa and Google Home/Google Assistant voice control through linked app accounts. Availability depends on the relevant account, region and services; a voice assistant does not remove the need for the module's Wi-Fi connection.
Group compatible devices for coordinated switching where the app offers grouping. The app's device or home-sharing tools let household members receive authorized access without sharing your account password. Grouping does not increase the module's electrical capacity.
A schedule is different from a countdown
A schedule is useful for a chosen operating time or daily routine. A countdown provides a delayed switching action. Check the selected channel, action and repeat days before saving, and verify the result with a suitable load after installation.
Menus depend on the installed firmware and app version. Do not assume random timers, cycle modes or a particular power-restoration setting merely because another similar-looking module offers them.
Useful ways to organize two lighting groups
These examples depend on correct wiring, compatible loads and suitable app options. This product is presented for on/off control, not brightness adjustment or curtain-motor control. Energy measurement is not among the confirmed features of this listing.
- Main and decorative lighting in one room: control the groups separately instead of switching everything together.
- Two suitable shop-lighting groups: arrange operating hours while keeping compatible wall switches available for everyday use.
- A bedtime or closing-time routine: group supported lights or use an appropriate schedule so fewer separate app actions are needed.
- Shared household control: give authorized family members app access while retaining the familiar wall controls.

Check the installation before choosing the module
- Neutral is required. The printed connections include N-in, L-in, L1, L2, S1 and S2; a qualified electrician must follow the device's matching wiring information.
- The combined load must respect the module's 10 A maximum. Channel limits, LED-driver starting current, wiring and the type of load must also be assessed; do not interpret the label as 10 A per channel.
- Check the enclosure's usable space, wiring clearance and suitable installation conditions. A compact housing does not guarantee that it fits every wall box.
- Use the required circuit protection. This switching module is not a protective breaker, and an OFF indication in the app is not proof of safe electrical isolation.
After professional installation
- Install Smart Life or Tuya Smart, sign in and confirm that a 2.4 GHz Wi-Fi network is available where the module is installed.
- Follow the unit's matching instructions to enter pairing mode. Use Add Device in the app and enter the Wi-Fi credentials; do not guess a reset sequence from another model.
- Name the two channels clearly. Check app switching and compatible wall-switch operation, then add suitable schedules or supported voice-account links.
- If pairing fails, check the network band, password, app permissions and signal first. Have the electrician investigate installation or wiring issues rather than opening an energized enclosure.
Questions before buying
Can I connect 10 A to each channel?
No. Do not add two separate 10 A allowances together. Keep the combined load within the module's maximum and have the electrician confirm all channel and load limits.
Will it work without a neutral wire?
This version requires neutral. Do not substitute a no-neutral wiring diagram from a different product.
Does the wall switch become unnecessary?
You can keep compatible wired wall controls with correct installation and configuration. Using the phone does not have to replace everyday wall-switch operation.
Does it need a Zigbee hub?
No. This is the 2.4 GHz Wi-Fi version. Away-from-home app control and voice services need their relevant network connections.
