Kasa Smart EP40A Outdoor Smart Plug: Apple HomeKit support for Siri control
For the homeowner who wants to transform their backyard into a welcoming space without constant trips to the switch, this outdoor smart plug offers effortless control. While many focus on security, think of it as your personal lighting concierge, ensuring your patio or garden is always ready for relaxation or entertaining.
You can schedule your string lights to turn on at dusk, so you never come home to a dark yard. The two outlets work independently, letting you power your fairy lights and a fountain separately. With voice control via Siri, Alexa, or Google Assistant, a simple command adjusts everything from your phone, even when you're away. The IP64 rating means it withstands rain and dust, so you can set it and forget it.
