The thermostat cannot be discovered or added in the Kasa app during setup.

Steps:

• Enter pairing mode: Follow the thermostat’s instructions to enter setup or AP mode (often involves holding a specific button or menu option until a Wi-Fi icon blinks).
• Phone Wi-Fi: Ensure your phone is connected to the same 2.4 GHz network you plan to use for the thermostat.
• App permissions: Allow the Kasa app access to location and local network if prompted, as some OS versions require this for device discovery.
• Restart devices: Reboot your phone, router, and power cycle the thermostat, then retry pairing.
• Alternative method: If supported, use Bluetooth or QR code pairing as described in the installation guide.
