Possible Causes

Thermostat not in pairing mode, Phone not connected to correct Wi‑Fi band, App permissions disabled, Firmware glitch in Wi‑Fi module

How to Fix / Troubleshooting

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.
