I use this brand at home and have found it very reliable.

This TP-Link WiFi Smart Plug Lite 2-Pack drops to $14.99 at Amazon. Shipping is free over $25, with a Prime account, or with a free Prime trial. Otherwise, it starts at $5.99. That's the best overall price for two by $3. These devices connect to your home WiFi network, and you can turn them on and off using a smartphone or an Amazon Alexa voice-controlled device. Sales tax is charged in most states.
