Sonoff TX Ultimate in 2026: Is This Classic Smart Switch Still Worth Buying?

Last updated on March 1, 2026

Sonoff TX Ultimate 2026 Review: A Modern Classic Revisited

When the Sonoff TX Ultimate first launched back in 2023, it completely redefined what a smart switch could look like. Three years later, in this Sonoff TX Ultimate review for 2026, we’re taking a hard look at whether its futuristic design, complete with an RGB LED halo and haptic feedback, has stood the test of time. More importantly, we’ll see how it stacks up in today’s smart home landscape, now dominated by Home Assistant and the mature Matter standard. After extensive long-term testing, I’ve found that while its hardware remains impressively robust, its true value in 2026 lies in its incredible integration versatility.

Performance and Technical Specs in 2026

While the specs haven’t changed, it’s crucial to analyze them from a 2026 perspective. At its core, the device is still powered by a potent ESP32 chip—a decision that has proven to be exceptionally forward-thinking, guaranteeing its relevance and upgradability for years.

Its 2.4GHz Wi-Fi connectivity might seem basic by today’s standards, but for IoT devices that don’t need massive bandwidth, it remains the most stable and reliable option. In my experience, this has ensured a rock-solid connection, free from the interference that can plague crowded 5GHz networks.

Home Assistant Integration: From Cloud to Full Local Control

The true power of the TX Ultimate in 2026 is unleashed when you break it free from the stock eWeLink ecosystem. For Home Assistant users, this switch is a dream come true, offering multiple paths to total local control.

Matter-over-Wi-Fi Compatibility

One of the most significant updates to the Sonoff 2026 firmware for the TX Ultimate lineup is official Matter support. This allows for direct, local integration with Home Assistant and other platforms like Google Home or Apple Home without ever needing to flash custom firmware. In my tests, pairing was seamless and response times were virtually instantaneous, showcasing the maturity of the Matter standard.

Limitless Customization with ESPHome

For absolute, unparalleled control, flashing the device with ESPHome is still king. Thanks to its ESP32 chip and easily accessible flashing pads, the process is straightforward for users with a bit of experience. With ESPHome, you can control each of the 28 RGB LEDs individually, fine-tune the haptic feedback and sound, and, most importantly, program advanced multi-touch gestures that aren’t available on the official firmware.

For example, I’ve configured a vertical swipe to dim my office lights and a long press to trigger a ‘Movie Night’ scene. The possibilities are truly endless.

Features That Still Make a Difference

Design and User Experience

Let’s be real: the design is still the TX Ultimate’s killer feature. The full-face panel that illuminates and reacts to your touch sets it apart from every other switch on the market. The 28 RGB LEDs aren’t just for ambient lighting; they can be configured in Home Assistant to reflect states: turn red when the security alarm is armed, pulse blue when rain is in the forecast, or glow green when your home’s energy consumption is low.

Advanced eWeLink Gestures and Scenes

The official firmware has seen significant improvements. Advanced eWeLink scenes now allow swipe gestures (left/right) to not just trigger a single scene, but to cycle through a predefined list. For instance, a right swipe can now switch between ‘Relax,’ ‘Reading,’ and ‘Focus’ modes, making control far more dynamic without ever opening the app.

Installation and Safety Considerations

Physical installation requires a neutral wire, which is standard in most modern US homes but something to double-check in older properties. **Crucially for US buyers**, this device is designed for a standard 86x86mm EU/UK square wall box and will not fit a standard US rectangular gang box without modification or an adapter.

One point of debate at launch was the exposed terminals. While this design makes them easily accessible for flashing, it is absolutely critical to always kill the power at the circuit breaker before handling the switch. Safety first.

2026 Price, Discount, and Where to Buy

The passage of time has made the Sonoff TX Ultimate much more affordable. In 2026, its price typically ranges from $28 to $40, depending on the number of gangs and current promotions. It remains an excellent value for the premium design and feature set it offers.

Sonoff TX Ultimate Alternatives

The 2026 market has seen some interesting competitors emerge. The main alternatives to the Sonoff TX focus on different protocols:

• Zigbee Switches: Models like the SONOFF ZBM5 offer superior network reliability thanks to the Zigbee mesh and have incredibly low power consumption. They’re a perfect choice if you already have a powerful coordinator like the SMLIGHT SLZB-06 and run Zigbee2MQTT.
• Native Matter Switches: Brands like Aqara and Eve have launched switches that run on Thread, providing a mesh network similar to Zigbee but under the official Matter umbrella.
• Other Wi-Fi Options: Shelly remains a top contender with its in-wall relays that install behind your existing traditional switches, allowing you to maintain your home’s original aesthetic.

However, none of these competitors can quite match the unique design statement and the visual and tactile user experience that the TX Ultimate delivers.

Conclusion: Is the Sonoff TX Ultimate Still Worth It?

After years of continuous use and conducting this in-depth 2026 review, my answer is a resounding yes—but with a caveat. If you’re looking for a smart switch that doubles as a design centerpiece and you’re willing to integrate it with Home Assistant to unlock its full potential, the Sonoff TX Ultimate is still an almost unbeatable choice.

Its updated Matter compatibility makes it accessible for beginners, while the ability to flash it with ESPHome keeps it a firm favorite among DIY enthusiasts. It’s a device that has aged with incredible grace, proving that great hardware design built on a versatile chip like the ESP32 is a long-term investment for any smart home.
