Sonoff T1 UK 2 Channels WiFi+RF+Touch Smart Switch
Sonoff T1 UK 2 Channels WiFi+RF+Touch Smart Switch
The Sonoff T1 UK 2 Channels is a dual-channel smart wall switch that combines WiFi, RF wireless, and capacitive touch control technologies for comprehensive home automation. Professional electricians and automation integrators use this device to retrofit existing UK-standard switch installations with smart control capabilities without requiring neutral wire connections. This product solves the critical challenge of adding IoT control to legacy electrical systems while maintaining aesthetic compatibility with standard UK wall plates.
Product Overview
The Sonoff T1 UK operates on a hybrid control architecture integrating three independent control pathways: WiFi connectivity via 2.4GHz IEEE 802.11 b/g/n protocol for remote access through the eWeLink application, RF wireless control on 433MHz frequency for local operation without internet dependency, and capacitive touch sensing for direct physical interaction. The device features a dual-relay configuration rated at 10A per channel, enabling simultaneous control of two separate lighting circuits or appliances from a single faceplate installation. The capacitive touch interface eliminates mechanical moving parts, reducing wear and extending operational lifespan to 100,000+ actuations per channel.
This UK variant specifically conforms to BS 1363 electrical standards and integrates seamlessly into standard UK single-gang or double-gang switch boxes with minimal modification. The device operates on a wide voltage range of 100-240V AC at 50/60Hz, making it compatible with both UK domestic and commercial electrical installations. Advanced features include status feedback LEDs for each channel, momentary and toggle switching modes, scene automation capabilities, and integration with major smart home ecosystems including Google Home and Amazon Alexa through cloud synchronization.

How to Use
Installation requires switching off power at the circuit breaker before beginning work. Identify the live conductor, switched return, and earth wire from your existing switch installation. Connect the live wire to the L terminal, switched return to the S terminal, and earth to the ground symbol terminal. Mount the device in your existing UK switch box, ensuring the faceplate aligns flush with the wall. Power on the circuit and verify LED indicators illuminate on both channels. Download the eWeLink application from your device app store and create an account using your email address or mobile number.
In the eWeLink app, tap the plus icon to add a new device and select Sonoff T1 UK from the product list. Ensure your smartphone is connected to your WiFi network and place the switch within 2 meters of your router during initial pairing. The device will broadcast an access point that your phone will automatically detect. Select your home WiFi network from the in-app list, enter your WiFi password, and confirm. The device will connect within 30 seconds, indicated by a solid green LED. You can now control both channels remotely, create automation rules, and assign the switch to specific rooms for voice control integration with Alexa or Google Home.
Frequently Asked Questions
Does the Sonoff T1 UK require a neutral wire connection?
No, this is a key advantage of the Sonoff T1 UK design. It operates on the live and switched return conductors only, making it compatible with older UK electrical installations where neutral wires may not be available at the switch location. This eliminates the need for expensive rewiring in period properties or heritage buildings.
What is the maximum load capacity and can it control high-power appliances?
Each channel is rated for maximum 10A at 250V AC, equivalent to approximately 2.5kW per channel. This supports standard residential lighting circuits, small heating elements, and most household appliances. For loads exceeding 10A, you should use the Sonoff T1 UK to control a contactor relay rated for higher amperage rather than connecting the load directly.
Can I use the RF remote control without WiFi connectivity?
Yes, the RF 433MHz control pathway operates independently of WiFi. You can purchase a separate Sonoff RF remote control transmitter to operate the switch locally without internet connectivity. This provides backup control during WiFi outages and enables operation in areas with poor network coverage, such as basements or shielded rooms.
Is the device compatible with 2-way switching installations?
The Sonoff T1 UK can replace one switch in a 2-way lighting circuit by connecting it to the switched return wire. However, the second switch location will require either removal or replacement with a dummy switch. For true 2-way smart control, you would need to install Sonoff devices at both switch locations and disable the mechanical switching at one location.
What smart home platforms does this device integrate with?
The Sonoff T1 UK integrates natively with Amazon Alexa, Google Home, and Apple HomeKit through the eWeLink application. It also supports IFTTT for advanced conditional automation and can be integrated with other smart home hubs through standard WiFi protocols. Ensure your router supports both 2.4GHz and 5GHz bands, as the device operates exclusively on 2.4GHz.
