I have two NodeMCU-ESP32 devices. Device 1 works perfectly (shows "device 1" in Agent Box). Device 2 connects to Wi-Fi, appears "online" in the MCP section, but in the Agent Box it shows "unlink" and "device 0".

I have two NodeMCU-ESP32 devices.
Device 1 works perfectly (shows "device 1" in Agent Box).
Device 2 connects to Wi-Fi, appears "online" in the MCP section, but in the Agent Box it shows "unlink" and "device 0".
When I speak, the assistant says "No device is available".
I have reflashed, reset, regenerated tokens, and re-bound multiple times – same result.
