Interact Pro App is now renamed as Signify Interact Builder
Lighting commissioning and control app
Welcome to the Signify Interact Builder App for the Interact Pro system, enabling installers to do commissioning and testing, and business owners to manage the lighting system.
Version History Improvements
- The performance of Bulbi voice support is improved.
- To enhance Bulbi’s support, updates are ongoing to online documentation and knowledge base content.
Bug fixes
- An issue where graphical energy data displayed in the Interact Builder web portal did not match the energy data from the CSV energy report is fixed.
- An issue with the .pdf installation report where the installation date reflected the day when the report was generated is fixed.
- An issue with networks where gateways had been removed but the network still appeared in the network list when creating a schedule is fixed.
- An issue where Zigbee Green Power (ZGP) device messages generated excessive wireless traffic in the network, degrading the ZGP device operational reliability is fixed. 4.28.3 Aug 3 Networks can now be unlocked instantly by any authorized expert user within a project, removing dependency on the original account that locked the network, without any support tickets.
Note: To ensure optimal system performance and consistency, we recommend redeploying unlocked networks and synchronizing all changes with the cloud.
Improved app loading performance and addressed various bug fixes to enhance overall stability and user experience. 4.25.4 May 11 We’re excited to introduce Offline Commissioning with a simple Start–Stop workflow:
- Start Commissioning: Download network data when internet is available
- Work Offline On-Site: Complete all setup activities without internet
- Stop Commissioning:Sync all changes to the cloud once internet is available
- Track Status Easily:View networks still in commissioning mode
- Smart Reminders :Get alerts to stop commissioning and sync changes
- Performance improvements and bug fixes 4.23.10 May 4 Key Enhancements
Improved Firmware Upgrade Handling
The system now supports multi-step firmware upgrades for lamps and gateways.
Devices with older firmware versions will automatically follow a sequential upgrade path, ensuring compatibility at each stage before reaching the latest version.
This improves reliability and prevents failures caused by skipping required intermediate versions.
Bug Fixes & Improvements
Firmware Update Stability
Addressed issues where firmware updates failed when upgrading:
From older versions to the latest version using BLE (Bluetooth) OTA
From intermediate versions directly to the latest version via Direct OTA
Introduced a controlled upgrade flow requiring intermediate versions where needed (e.g., upgrading via version 7.2.15 before reaching 7.5.5).
Improved handling of device limitations (such as storage constraints) to prevent update failures.
System Configuration Reliability
Fixed an issue where configured scenes stopped working after switching to gateway mode.
Scene functionality is now consistent across switches and light control after deployment.
Additional Updates
Documentation, Support and app name
Ongoing updates to knowledge base content to better support Bulbi.
The Interact Pro app has been renamed to Signify Interact Builder.
New Features
Supports standard DALI drivers (without Part 251/252/253) when used with a mains-powered DALI sensor.
BACnet integration enabling lighting scene override and real-time occupancy status sharing. The BACnet integration is an on-prem, and an IP-based communication between the interact gateway and a third-party BACnet system. It supports manual control and occupancy data reporting of lighting groups.
Web portal – Integration app to enable BACnet Integration & Export BACnet CSV.
Web portal project search functionality enabling search by project name, project type, and date of creation.
Bug Fixes
Fixed issue that caused sensors to lose their group assignment
Energy CSV reports now successfully generate with 15-minute data granularity
