Recommended to give them a static IP via DHCP lease on your router config (not required). Then go into each device and turn OFF cloud binding. I do not even have the integration app logged into the cloud at ALL. I do it all locally.
Also, if you had 2FA turned on for your account, if it was trying to renew the token and hitting the 2FA question that might be why it goes null. I don't use the Kasa cloud at all except the mobile app to pair new devices so not totally sure.
Assuming you are using this? @djgutheinz [RELEASE] TP-Link/Kasa Plug, Switch, and Bulb integration
