Sonoff Zigbee Bridge Ultra vs X-Sense SBS50 Base Station

Full Smart Hubs comparison in 2026

Data from the official Sonoff and X-Sense sites.
2026 verdict
Sonoff Zigbee Bridge Ultra is the clear winner among general smart home hubs here, ahead of the X-Sense SBS50 Base Station on connectivity, protocols and platform integrations.
As a Zigbee coordinator and Matter bridge with both Wi-Fi and Ethernet, it manages up to 256 devices and reaches Apple Home, Google Home, Alexa, SmartThings and Home Assistant, while the SBS50 has no Zigbee or Matter of any kind and reaches only Alexa and Home Assistant. The SBS50 answers on the numbers that matter to a budget buyer: it costs less, carries a five-year warranty against the Sonoff bridge's two years, and holds a slightly higher rating. The two are not really competing for the same shelf space, though: the Zigbee Bridge Ultra is built to run a general Zigbee smart home, while the SBS50 exists solely to interconnect X-Sense smoke, CO, heat and water leak alarms. Choose the Sonoff Zigbee Bridge Ultra to build or expand a Zigbee and Matter smart home; choose the X-Sense SBS50 Base Station only if X-Sense alarms are your home's safety system.
