### 1/5 — Unbrauchbar und langsam

*2020-11-06*

Haben einen Zahnarzt Praxis mit Philipp leuchten und Meldern installiert. Über die App sollte man alles programmieren. Die App ist sehr langsam und das programmieren eine Qual. Beleuchtung funktioniert bis heute nicht richtig. Ein Stern ist meiner Meinung nach immer noch zu viel. Gibt bessere Alternativen auf dem Markt klare nicht Empfehlung 👎🏼

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.
