SONOFF TX Gen2 vs Fusion Button
connectivity
The SONOFF TX Gen2 Touch Wall Switch uses 2.4GHz Wi-Fi to connect directly to your network. This allows remote control via the eWeLink app without needing a separate hub. You can sync it with Apple Home, Google Home, and Amazon Alexa. The SONOFF Wireless 4-Button Zigbee Scene Switch relies on Zigbee technology. It requires a compatible hub, such as the SONOFF ZBBridge or iHost, to function. It also supports SmartThings and Home Assistant. Wi-Fi offers direct internet access, while Zigbee provides a local mesh network. Your choice depends on whether you prefer hub-free simplicity or mesh reliability.
smart home compatibility
The TX Gen2 switch supports Matter, which helps break down ecosystem barriers. It integrates seamlessly with Apple Home, Google Home, and Amazon Alexa for cross-platform voice control. This ensures unified management of lights and appliances. The Fusion button focuses on Zigbee ecosystems. It works with SmartThings, Home Assistant (via ZHA and Z2M), and Zigbee2MQTT. It also offers dual modes for the SONOFF eWeLink ecosystem. If you use Apple or Google Home natively, the TX Gen2 is easier to set up. If you run Home Assistant, the Fusion button offers deeper local control.
wiring requirement
Installation methods differ significantly between these two devices. The TX Gen2 is a wall switch that fits standard 120-type panels in North American junction boxes. It supports neutral-wire power setups, requiring a permanent electrical connection. The Fusion button is completely wireless. It requires no wiring and can be placed on a desk, attached to metal surfaces with its magnetic base, or mounted with screws. You can also install it in a standard 86-type wall box. If you want a permanent fixture, choose the TX Gen2. For flexible placement without electrical work, the Fusion button is the better option.
programmability
The Fusion button offers extensive programmability with four buttons. Each button supports single, double, triple, and long-press actions, creating up to 16 customizable scene triggers. You can control lights, routines, and appliances with specific press patterns. It also supports TouchLink lighting control for direct dimming. The TX Gen2 focuses on relay control. It features an independent relay mode to prevent smart lights from going offline due to physical button presses. It supports scheduled timers and automated scenes via the app. The Fusion button provides more granular input options, while the TX Gen2 ensures stable relay states.
build
Physical dimensions and form factors vary. The TX Gen2 measures 2.91 inches in width and 4.72 inches in length, weighing 4.7 ounces. It is designed to replace standard wall plates. The Fusion button is compact, measuring 1.97 inches square and 0.88 inches thick, weighing 3.53 ounces. It is small enough to hold in one hand or mount discreetly. The TX Gen2 includes a dimmable LED button indicator for nighttime visibility. The Fusion button lacks a display but uses a magnetic base for versatile positioning. Choose the TX Gen2 for a permanent wall presence, or the Fusion button for a portable remote.
