I think I have the US version of the Amazon Smart Plug. I got creative to get it working with HA. I used the Samsung SmartThings free cloud service even though I do not own a SmartThings hub. I am using Hassio & DuckDNS / LetsEncrypt to expose my HA instance to the Internet.
I set up a virtual device handler that is both a binary switch & a sensor. Some people call this an “Alexa Switch”. When the switch is triggered, it triggers the sensor. an Alexa routine controls the smart plug depending on the state of the sensor. I then created a virtual device based off that handler.
so, HA → SmartThings → Alexa
I modified code I found online for the “Alexa Switch” Here it is.
