@johno42 You don't connect things to Alexa. You install skills in the Alexa app to control your smart devices.
If you use the kasa app, then use the kasa skill.
If you use the tapo app, then use the tapo skill.
The skill will need your TP-Link account authentication to allow Alexa/Amazon to control the devices.

I have no idea, I'm trying to get alexa to work with my P100 smart plug, but I can't find it anywhere on this stupid app. Please can anyone help before I pack it back in the box and send them back along with the cameras and the alexa. ?
