Tapo and Kasa Devices Unable to be Controlled in the App
67120 This FAQ will walk you through a few typical cases for troubleshooting a Kasa or Tapo device that their app cannot control.
Case 1. I cannot use the Tapo or Kasa app to control my smart devices in the local network
- Check the smart device's LED status as per the User Guide. If the LED status shows that the device is not working properly, please reset and re-configure it.
- If the smart device was working fine before, confirm if there are any changes in the router or the network environment.
- Go to the “Device Settings” page on the Tapo or Kasa app to check the signal strength of the Tapo or Kasa device.
- If the signal strength ranges from -60dBm to -40dBm, the smart device has a good signal from the router.
- If the signal strength is less than -60dBm, the signal strength from the router is too weak. In this case, please move the smart device closer to your router for a try.
- Upgrade the smart device to the latest firmware
Case 2. I cannot use the Tapo/Kasa app to control my smart devices remotely
- Make sure you can control the smart device in the local network. If you cannot, please refer to Case 1 to troubleshoot.
- To upgrade the smart device to the latest firmware, you may refer to the instructions:
- Change the DNS server to 8.8.8.8 on your home modem/router.
- Ensure the router is working properly. Connect your phone or laptop to the router's Wi-Fi network and check if the device has internet access.
- Disable firewall settings if there is one on your home router, then reboot the router.
