I recently encountered an issue with my Fenster Drehgriff sensors where the firmware update wasn’t completing as expected. Initially, one sensor updated smoothly from version 1.9 to 2.0 overnight, but the other two sensors remained stuck at 1.9 with persistent service messages. This was puzzling, especially since all sensors were installed similarly.After some research, I discovered that these sensors don’t update automatically, which was a bit of a letdown. I decided to take a hands-on approach. Here’s what worked for me:1. Manual Update Process: I found that the sensors need a manual firmware push. This involved accessing the settings menu on my hub and selecting the specific sensor to update. It was a bit tedious, but worth it to ensure all sensors were on the latest firmware.2. Rebooting the Hub: Before initiating the update, I rebooted my hub to ensure there were no connectivity issues. This step seemed to make a difference, as the update process was smoother afterward.3. Patience and Monitoring: The update didn’t happen instantly. I kept an eye on the sensors over a couple of days, and eventually, the firmware updated without further issues.It’s a relief to have all sensors functioning correctly now. This experience taught me the importance of manual checks, especially for devices that don’t handle updates automatically. If anyone else is struggling with similar issues, I’d recommend trying a manual update and ensuring your hub is fully rebooted before starting the process.Overall, it was a bit of a challenge, but resolving it gave me a great sense of accomplishment. Happy updating everyone!
