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

Get this TP-Link Kasa Smart WiFi Plug Lite 3-Pack for $20.99 at Amazon. Shipping is free over $25, or with a Prime account or free Prime trial. Otherwise it adds $5. This was the best price for three that we found by $5. 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.
