The EufyHome smart light switch is down to $17.99 on Amazon. This light switch usually sells for $30 and hasn't dropped from that price directly since last September. Back then it also dropped to $18, so this is a match for the lowest price in the last year. Previous sales haven't lasted more than a couple of days, so be sure to grab one before the price goes back up.

Eufy is the Anker division that specializes in smart home equipment for the home. In this case, it's a smart light switch you can use to replace a normal light switch. The new switch has three modes, including Schedule, Timer, and Away. Use these to customize your lighting situation. Turn the lights on or off when you need to. Set the Away mode when you leave so it looks like someone is turning the lights on and off randomly to deter intruders.

The switch is smart enough to work with your smart home ecosystem without needing a separate hub. Connect it to your 2.4GHz Wi-Fi network and add it to your Amazon Alexa or Google Assistant. Then you can just use your voice to get your lights to do what you want.

You don't have to worry about safety, either. The switch is made with a flame-retardant casing. Plus, it comes with an 18-month warranty. Users give it 4.1 stars out of 5 based on 99 reviews.
