How to reset TP-Link Kasa smart switch and plug

• If you use any third party software like Alexa, Google, etc, make sure you've removed the settings for kasa switch, or you could uninstall it temporarily for a test. 
• To check if the problem relates to software or hardware, after the factory reset, please leave in factory default state for half a day (Led flash green and amber) and observe the performance. Will the smart switch turn off in factory default state? 

Then you could reinstall the device in the Kasa APP and see if reset solve the issue.
