They do not have a current integration.
There is a workaround, but Iām not sure itās for ārookies.ā You have to create a simulated sensor, turn that sensor on from smartthings, and use that as the trigger for an Alexa routine (not a smartthings routine) which can then turn the smart plug on or off.
This works, but can be a little glitchy. So let us know if you want to learn more about it.
Hereās the community FAQ for this kind of situation. The topic title is a clickable link.
Also, as a personal favor, in the future would you please write thread titles which are specific to the brand and device model that you are asking about? This is a very busy forum and most people only read the threads that they are specifically interested in. The more specific your thread title, the more people who will read it, and the more helpful the forum becomes as an information archive.
