Description

Neither smart plug described here is sold for aquariums, and neither listing mentions one. Both are household Wi-Fi plugs that switch whatever is plugged into them on and off from a phone app, by voice, or on a schedule. Because no reference work we searched covers these plugs, the details come from two Amazon listings: Kasa's, the most-rated plug in our Amazon search results, and an Amazon Basics plug whose title names its timer function. Kasa's HS103P4 is a pack of four plugs with a current rating of 15 A at 120 volts. The listing says they need a 2.4GHz Wi-Fi connection but no hub, that the free Kasa app turns connected devices on and off from anywhere, and that they work with Alexa and Google Home Assistant for voice control. Timer or countdown schedules can switch an appliance on and off automatically. In the app, a countdown timer turns an appliance off when the time runs out, and Away Mode switches things like lamps on and off to make it look as if someone is home. The Amazon Basics plug is set up and managed in the Alexa app and, as its title says, works with Alexa only; the listing adds that no third-party app or hub is needed. It connects over 2.4 GHz Wi-Fi and lists an amperage of 15 A. It can be scheduled to turn on or off at set times, by voice command, or at sunrise and sunset, and the seller names lights and fans among the appliances it can switch automatically. The plug is designed to fit one socket and leave the other outlets free. Neither listing mentions dimming. Both describe on and off switching only, and the sunrise and sunset option on the Amazon Basics plug turns it on or off at those times.
