Hey everyone, I wanted to share my experience integrating Shelly devices with the Fritz WLAN system. I recently faced an issue where my Shelly devices would stop working when switching between different access points. After some research and troubleshooting, I found a reliable solution. Here’s how I approached it:
-
Understanding the Problem: My setup includes a Fritz WLAN mesh and an additional repeater. When one AP was deactivated, the Shelly devices would lose connection with Home Assistant, even though their web interfaces were still accessible. Restarting the Raspberry Pi was the only workaround, which was inconvenient.
-
Research and Testing: I explored the Shelly integration within Home Assistant and discovered that the issue might be related to how the devices handle IP address changes. I tested different configurations and found that using static IPs for the Shelly devices significantly improved reliability.
-
Solution: By assigning static IPs through the FritzBox router, I ensured that the Shelly devices maintain consistent network connections. Additionally, I updated the Shelly firmware to the latest version, which enhanced stability and performance.
-
Outcome: After implementing these changes, my Shelly devices now function seamlessly across different access points without requiring manual restarts. This has greatly improved my smart home setup’s reliability.
If anyone else is experiencing similar issues, I recommend checking your device’s IP configuration and ensuring all firmware is up to date. It’s a simple yet effective solution that can save you a lot of hassle.
Happy integrating!
