The green icon likely means the device connected to flow.m5stack.com successfully, but the API key connection might need extra steps. First, ensure you entered the API key correctly in UIFlow Web. Also, check if your firewall or network settings block the device from appearing in Fritzbox. For logs, try enabling debug mode in the M5Stack settings or use serial output to inspect connection details. Sometimes, the device uses a separate network interface that Fritzbox might not show. Double-check your Wi-Fi credentials and restart both device and router.
