SONOFF ZBBridge-U Zigbee Matter Bridge Ultra Smart Home Security Ethernet Connection OTA Upgrade Works SNZB-01P/SNZB-06P Devices
Smart Electronics
“SONOFF ZBBridge-U is a Zigbee 3.0 Matter bridge with an EFR32MG21 radio and a 1.5GHz dual‑core CPU plus 1GB DDR4 and 8GB eMMC storage; it supports up to 256 Zigbee sub-devices, offers Ethernet connectivity, local MQTT sync and a Turbo Mode that extends radio range. For smart‑home integrators who need local bridging into Matter (and Home Assistant MQTT syncing) it’s a technically capable bridge with extended range options; note it functions as a Matter bridge (not a standalone Matter controller) and requires a separate Matter hub for full platform control.”
