I am using Yeelights integrated on Smartthings system throught the Smartthings app and It works almost fine.
However, like every 2 days, Yeelight account is disconnected from the Smartthings app and I have to login yeelight again to regain control of yeelight devices.
Already contacted Smartthings support and I have been told it’s an issue with Yeelight and it’s integration.
