WiFi smart sockets to control home appliances have been around for a few years, and one of my favorite companies is Sonoff as they offer a variety of affordable smart plugs pre-loaded with eWelink firmware and compatible with open-source firmware like Tasmota and ESPurna.
The company is also attentive to safety. communicate issues with customers, and recently wrote a post entitled “Safety is our responsibility” where they detail all steps taken to make sure their mains connected device sare safe to use. Sadly that does not include safety certifications like UL/ETL, or TUV which may have implications for your home insurance depending on where you live, and for peace of mind, it’s always good to have a third verify your design for safety.
Which brings me to the main point of this point, as a UL-certified dual-outlet smart socket, namely TP-Link Kasa Smart Plug, is currently on sale for $19.99 when ticking for the $10 discount coupon. [Update: They also have a promo for an UL-certified smart switch for $14.99]
