work for you?
Amazon: Zigbee Smart Plug, SONOFF S31 Lite, 2-Pack, Works with SmartThings, Amazon Echo - $15.74
NOTE: This is NOT a WI-Fi plug. It uses the Zigbee protocol. A Zigbee hub of some type is required like SmartThings.
I also observed for me that the sale price does NOT show up if I am not logged into my Amazon account.
