if You decide to go that way, you can use a special virtual motion sensor the shows up as a motion sensor on Alexa and a Switch on HE. When you turn the virtual switch on you will simulate a motion sensor activating in the Alexa app. So you then just make a routine so when that motion sensor turns on, your switch turns on. However, the virtual motion sensors as a switch is better as a trigger, because it turns back off after a few seconds. I don’t know why, it’s just the way it behaves. So you would also need a second motion sensor as switch and a second routine to turn the switch off. Then you would have to create a rule to flip each one of those with another Virtual Switch.
If you want to try, even without having the out let on hand, you can see what’s involved by just controlling a virtual switch. Here’s the custom driver you’ll need.
It works, but you can see how complex it gets just for a plug. And it’s a cloud based outlet. Have to agree. Stick with Zigbee and Zwave.
