Version 3.9.0 (2026/09/10)

Expanded Device Compatibility:

Added support for SONOFF TP-WGZBA Zigbee/ Bluetooth dual-mode thermostat panel.  
Matter Bridge Updates:

Added support for syncing the following Matter-supported device types to Matter-enabled platforms via Matter Bridge:  
Pressure Sensor  
Added support for exposing additional Air Quality Sensor measurements via Matter Bridge:  
Formaldehyde concentration  
Nitrogen dioxide concentration  
Ozone concentration  
PM1 concentration  
PM10 concentration  
Radon concentration  
Expanded Boolean State Configuration cluster support for:  
Occupancy Sensors now support sensitivity adjustment.  
Water Leak Detectors now support enabling or disabling tamper alerts.  
Optimizations:

Changed Matter Bridge mapping for multi-function devices to use multiple endpoints instead of compose, improving device compatibility.  
SONOFF BASIC-ZB1GSP now supports bidirectional energy monitoring, with exported energy data available in history graphs.  
SONOFF SNZB-02UL can now use SNZB-02D, SNZB-02P, SNZB-02WD, SNZB-02LD, SNZB-02DR2, SNZB-02B, SNZB-02M, and other SNZB-02UL devices as external sensors, providing more accurate room temperature measurements.  
The Ethernet MAC address is now available in the Local Web Portal.  
SONOFF SNZB-03PR2 can now be used as a Smart Security alarm trigger.  
Automations now run immediately after creation or editing if their sub-device trigger conditions are already met.  
Updated BTHome device mappings over MQTT to represent supported capabilities more accurately.  
Optimized status cache handling for third-party sirens that do not automatically report status data.  
Bug Fixes:

Fixed an issue where ZBBridge-U could continue beeping when delayed arming was enabled with more than three sub-devices.  
Fixed an issue where Zigbee device syncing to Home Assistant could fail after MQTT recovered from an initial connection failure.  
Fixed an issue where SONOFF SNZB-09P was shown as “Unsupported” and could not be exposed to Matter-enabled platforms via Matter Bridge.  
Fixed the issue where the SONOFF presence sensor SNZB-06P24 frequently reports illuminance values.
