I use this brand at home and they have been very reliable.

Get this TP-Link Kasa Smart WiFi Plug Lite 4-Pack for $34.99 with free shipping at Amazon. This was the best price that we found for four by $15. 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.
