KS220M(US) 1.0 - Firmware 1.1.5 Build 241206 Rel.142818

Description

Occasionally, the smart switch may experience sudden freezing, during which the physical button becomes unresponsive for controlling the connected devices, and the switch appears offline in the app. A temporary recovery can be achieved by restarting the switch (using the Restart button located below the main control button).

Solution

This issue has been addressed in the latest official firmware 1.1.6 Build 250522 Rel.210254. 

Should your switch continue exhibiting this issue, please verify whether you’re using any third-party open-source platforms (e.g. Home Assistant) to manage Kasa devices. These platforms are not officially supported by Kasa, and their use may compromise product performance and stability. If currently in use, we recommend disconnecting your Kasa devices from these platforms and monitoring their behavior over time to determine if the issue persists.

If your ES20M or KS220M still shows this problem after disconnecting from unofficial third-party platforms, please contact our forum support team for advanced troubleshooting.
