The TP-Link Smart Plug is back on sale for $19.99 on Amazon. Apart from a brief Alexa-exclusive deal over a year ago, this is the lowest price that this plug has ever been. This is the same plug that Amazon was bundling for $5 when you buy any Echo device, so if you purchased an Echo device recently with this plug and wanted more of them, here’s your chance to get them at a great price. This switch can be directly controlled by Alexa without needing any hubs or other equipment. Just plug it in, set it up in the app, and you’ll be able to control it by saying “Alexa, turn on/off the [selected name]..”
