Hi everyone, I wanted to share my experience migrating from OpenHAB 2.5 to 3.3. It’s been quite a journey, filled with both excitement and frustration. I started by following the official documentation, which suggested using option 3 in openHABian-config for a seamless upgrade. However, things didn’t quite go as planned.
Initially, everything seemed fine. My items appeared in the system, but they were all showing as NULL. I encountered errors related to Samba not working and had to reboot multiple times. The most puzzling issue was with my THINGS—they were either showing as ONLINE or throwing an error: ‘ERROR: HANDLER’. My logs stopped updating, and I noticed all LINKS were removed, which I assume is related to the MAPDB persistence data issue mentioned in the docs.
Another major problem was with MQTT. The server was offline and uninitialized, which meant I couldn’t communicate with my devices. I wondered if I needed to reinstall Mosquitto entirely. After some research, I found that deleting the MAPDB persistence data was a potential fix, but I was hesitant to try it without more guidance.
I also noticed that the Basic UI wasn’t working as expected. After entering my username and password, I was directed to the initial setup page instead of the main dashboard. This was frustrating, as I expected a smoother transition.
Despite these challenges, I’ve learned a lot about OpenHAB’s architecture and the importance of proper configuration backups. If anyone has tips or tricks for a smoother migration, I’d love to hear them! Let’s keep the conversation going and help each other navigate this transition. Cheers!
