The subject smart plug (after configuration) runs swimmingly “out of the box” with HA Ver. 41.
It seems, though, to control the switch with Alexa, you must set up a TP-Link Cloud account - which then (as I understand it) requires an active internet connection to function.
Hence my question: Is it possible to add TP-Link smart switch Alexa support without the TP-Link cloud account?
I just added one last night without issue… (first TP-Link device I’ve owned) added the line - switch to exposed domains under emulated hue restarted Home Assistant and did device discovery from the Alexa web app.
