Zemismart TB26 Zigbee Paddle Light Switch – Wide Press Keys, Glass Frame, 1 to 3 Gang, US/4×2 Size (Neutral Required)
Please note: made for US and Latin American 4×2 back boxes. It does not fit standard UK 86mm back boxes. It needs a neutral wire and a Tuya Zigbee hub, and works on single-pole (one-way) circuits only.
A familiar paddle switch, made smart
The Zemismart TB26 is a Zigbee smart light switch with wide, flat press keys in a white glass frame, so it looks and feels like the wall switch it replaces. Press a key to switch the light, or control it from the Tuya Smart or Smart Life app, by voice, or on a schedule. Choose 1, 2 or 3 gangs.

Prefer flat push keys? See the ZM-808. Prefer glass touch? See the Zigbee glass touch switch. Want each key labelled on a screen? See the ZMS-206US.
Why choose the TB26
- Wide paddle keys with a quick, positive press.
- White glass frame with a slim white module.
- Blue indicator shows when a light is on.
- Zigbee, so it pairs to your hub and stays off your WiFi.
- Timers and countdowns in the Tuya Smart or Smart Life app.
- Alexa and Google Assistant voice control, plus Apple Home and Siri with a compatible Zemismart hub.


App and voice control
Add the switch to a Tuya Zigbee hub in the Tuya Smart or Smart Life app. Link the app to Alexa or Google Home for voice control. With a Zemismart Zigbee hub that supports Apple Home, it also appears in the Home app and works with Siri.


Timers
Schedule lights on and off, for example on at 18:00 and off at 22:00.

You will need a Zigbee hub
The TB26 needs a Tuya Zigbee hub to work with the app, timers and voice control. The hub is sold separately.



Pairing
- Make sure the hub and your phone are on the same 2.4GHz WiFi network.
- Power on the switch. If the indicator isn’t blinking quickly, hold the ON/OFF key for 7–10 seconds to reset it.
- In the Tuya Smart or Smart Life app, open your Zigbee hub, tap Add Sub-Device and follow the prompts.
Wiring
Connect live to LINE, neutral to NEUTRAL, and each light to LOAD 1–3. On the 1 and 2 gang, only the matching LOAD terminals are used.

Frequently asked questions
Will it fit a UK back box?
No. It’s sized for US and Latin American 4×2 boxes. For UK 86mm boxes, see the K6 Zigbee push button switch or the ZN-RS01E Zigbee touch switch.
Can I use it for two-way (3-way) switching?
Not by wiring. It’s for single-pole circuits. You can link two Zigbee switches in the app instead, so either one controls the light.
How much LED lighting can each gang take?
Up to 150W of LED lighting per gang (600W incandescent).
Does it need a neutral wire?
Yes.
Do I need a hub?
Yes, a Tuya Zigbee hub. For Apple Home, use a Zemismart hub that supports Apple Home.
Can I fit it myself?
We recommend a qualified electrician, following your local wiring regulations.
