To Support ESP-Claw
Search the AP esp-claw-XXXXXX, connect and config your WiFi. If the WiFi not connected, the ESP-Claw Offline mode.
When the esp-claw connected the WiFi, you can browser from the local IP, like: 192.168.x.x.
Then you can to config the LLMs and Telegram, Feishu, QQ, Wechat etc.
After the IM and LLM configureded, you can communicate with the device using your phone.
