Technical specifications for the SONOFF Zigbee Bridge Pro highlight a dual-core ESP32 architecture, representing a significant processing upgrade over its predecessors. Internal hardware analysis reveals a Texas Instruments CC2652P Zigbee chipset, which is notable for a +20dBm output power rating. This high-gain configuration provides superior RF range and wall penetration compared to standard Silicon Labs-based bridges.
The inclusion of a real-time clock (RTC) chip ensures that localized "Scene" schedules remain operational even if the Wi-Fi connection is disrupted. Aggregated data confirms a device capacity of up to 128 nodes when the mesh is supported by mains-powered routers. The unit is housed in a custom PCB layout developed by ITEAD, featuring a built-in buzzer for acoustic status indicators.
Key technical specifications include:
- Texas Instruments CC2652P high-output radio.
- Dual-core ESP32 processor for edge logic.
- Onboard RTC for internet-independent scheduling.
- Integrated status buzzer for system feedback.
For users who find the eWeLink ecosystem too restrictive, the Home Assistant Green offers a more flexible local-only control plane that can integrate this hardware as a remote coordinator.
This hub represents a high-performance entry in the smart bridge devices category due to its specialized RF chipset.
