[Costco] Charging Essentials Wi-Fi Smart Plug x 2 $18.99/Smart Dimmer Switch x 2 $39.99
Never heard about the brand name but I like to give it a try.
Edit: many people also bought a pair of WiFi smart dimmer switches for $39.99. Costco added a wifi outlet for $29.99 recently.
Edit: some places sell the mini plugs for $18.99 now.
Nice lower cost alternatives to brand names.
