Single-gang glass touch switch with Wi-Fi and RF433
A black glass wall switch with one circular touch control for one lighting circuit. Use it at the wall, through Smart Life / Tuya Smart, or with a compatible separately supplied RF remote. This is a mains-powered C-Smart switch, not a battery scene button and not a brightness dimmer.
It is useful when you want the familiar wall control to remain available while adding phone access and lighting routines. For example, switch a suitable living-room light off from the sofa, schedule hallway lighting for the evening, or give household members their own app access. These are uses of the connected lighting circuit, not extra outputs or built-in motion sensing.
Direct Wi-Fi connection
Connect to a 2.4 GHz Wi-Fi network for app control. This is the Wi-Fi version, so a Zigbee gateway is not required.
Smart Life / Tuya Smart
Use the app to switch the light, manage schedules and share access. Linked Alexa or Google Home accounts can provide voice commands, subject to service and language support.
Touch control and locating light
The circular touch area switches the light locally. A status indicator and lower fluorescent locating strip help you find the panel. The manufacturer also provides an app backlight setting; it is separate from the room-light output.
Timers and power-return choices
The manufacturer family offers timer modes and power-return settings. Check which options the installed unit exposes in its app and firmware before relying on a particular routine.
One circuit, several ways to use it
At the wall, use the button for ordinary switching. Through Smart Life or Tuya Smart, you can check and change the switch state while the device is connected. Remote access away from home depends on the home network, Internet connection and cloud service; an offline reminder is a connectivity notice, not a fault diagnosis or emergency alarm.
- Share the device with authorised household members instead of sharing your account password. Group compatible switches for a room-wide action; grouping does not create extra physical outputs on this single-gang unit.
- Alexa and Google Home are the principal voice options shown for this family. Other manufacturer-listed integrations, including SmartThings, depend on the actual account service, region and available device functions; they are not universal platform guarantees.
Turn useful routines into clear actions
The manufacturer lists 5 timer modes for this family. Availability and menu names depend on the supplied unit revision, firmware and app; the list below explains those family options rather than guaranteeing every mode on every unit. Confirm the desired mode in the installed device’s app, test a short routine and remove conflicting schedules.
- Schedule: choose a clock time for an action, such as turning hallway lighting on in the evening. Countdown: request an action after a chosen delay.
- Cycle: repeat on/off periods where the connected lighting is suitable. Random: vary timing within the available app settings; this is a convenience routine, not a security guarantee.
- Inching, if exposed by the unit’s app and firmware: a short-duration return action for an appropriate lighting routine. Its presence must be checked; it does not turn the switch into a dry-contact gate controller.
A compatible remote, with a clean glass finish
Pair a compatible RF433 remote
Choose a compatible learning remote, not simply any device labelled 433 MHz. The manufacturer specifies 433.92 MHz, ASK modulation and EV1527 encoding for this family. The remote is purchased separately. The quoted unobstructed range is up to 100 m; walls, position and radio interference can reduce it substantially.
- The manufacturer illustrates learning by quickly pressing the switch button 5 times, then the desired remote button 2 times. Confirm the result on the installed unit.
- The illustrated clear operation is 8 quick switch-button presses. Use it only when you intend to remove the learned RF association, not as a routine way to switch a light.
Glass, indicator and care
The matching family uses a 2.5D curved tempered-glass panel, with smooth-painted edges on the black finish. The manufacturer describes red and blue status lighting and an app option to disable the backlight. The bottom locating strip is a separate visual aid, not a night-light output for the room.

| RF range reference | Up to 100 m unobstructed; not a guaranteed indoor range |
Check the installation, then connect the app
This C-Smart family supports installation with neutral or without neutral. The no-neutral arrangement requires the specified capacitor at the lighting load; it is not a capacitor-free design. Ask a qualified electrician to check the actual terminals, load compatibility and wall box before purchase or installation. Do not copy a multi-gang diagram terminal-for-terminal onto the single-gang unit.
The manufacturer family reference lists AC 110–240 V, 50/60 Hz; this is not a reading from the supplied unit’s rear label. Before installation, have a qualified electrician verify the actual unit label, supply and each connected load, including the lamp driver’s starting behaviour. Use the confirmed unit rating, not a value from another gang count or a general family picture.
- Have the mains installation completed with the supply safely isolated. Follow the actual unit’s terminal markings and instructions, including the correct no-neutral capacitor arrangement where needed. The off state is not an electrical isolation method for maintenance.
- Connect the phone to 2.4 GHz Wi-Fi and enable Bluetooth for discovery. Open Smart Life or Tuya Smart and allow the permissions needed to add the device.
- Hold the wall button until its indicator flashes rapidly, then use the app’s discovered-device prompt or add-device flow. Follow the Wi-Fi credentials prompt and wait for completion.
- Give the light a clear room name. Test wall control, app on/off, the desired timer and power-return choice before linking voice control.
Before you choose
Can I use it where there is no neutral wire?
The matching family supports this arrangement with the specified capacitor at the load. Have the electrician confirm the exact single-gang unit, lamp compatibility and supplied accessories. Do not assume every no-neutral switch uses the same component or installation.
Does Bluetooth replace Wi-Fi when Internet is unavailable?
Not for this product. The manufacturer describes Bluetooth as part of network connection and says it cannot be used alone. Keep local wall control and a compatible paired RF remote distinct from cloud app control.
Do the multi-button gallery pictures mean several circuits are included?
No. This page offers the black single-gang switch. Some manufacturer illustrations show other gang counts to explain shared features. They do not change the purchased version, number of outputs or load rating; use the actual unit’s terminals and label.
What if the light switches unexpectedly?
Check schedules, countdowns, cycle/random/inching settings, group scenes and shared users first. If the behaviour continues or the switch becomes damaged, stop using it and have the installation checked; do not assume it is only an app problem.
Manufacturer references
