JUOYOU 2 Pack Smart Plug Outlet - Dual WiFi Smart Socket Works with Alexa & Google Home, 4-in-1 Design (2 Smart Outlets + 2 USB Ports), Remote Control via App, Timer Function, No Hub Required, FCC Certified - Perfect for Home Automation & Charging Devices

These use a weird 3rd party generic app to control. In doing so the instructions are not self explanatory. The steps are as any other setup but since the app must use a variety of branded smart home devices, it is difficult to find this device as one of the many many devices listed. I eventually found it but it was not obvious.These are *Not* ETL Certified / UL Listed -- despite someone's attempt to answer my question about this in the Customer Questions area. Nothing on the box or device itself displays the ETL or UL Listed insignia, which means it has *NOT* been certified. (Note this is entirely different than FCC Certified.)If you don't know why this is important, then read up on it. Basically ETL or UL certified means the devices have been thoroughly tested by an independent 3rd party to make sure it it safe to use -- i.e. won't start an electrical fire and burn your house down. (Rather important, if you ask me!) This testing is done per individual device model and it is expensive, and so if it was done, the manufacture would have proudly made a point of displaying this fact, typically right on the device itself (not just the box). Go ahead and look at all your electronic devices to see if it has either ETL or UL Listed on it. Beware of devices that are made by non-USA based companies, as they often are not safety tested in any rigorous way.I am returning this, and instead have bought the KMC brand smart plugs which are ETL Certified. They arrived last night and work great, also with the Smart Things app (and individual plug control). Unfortunately they do not make one with a USB port (yet), but I'd rather be sure I am using a safe product. So I will stick to using my USB adapter (also UL Listed) with it for now, until they make one that is also ETL/UL Listed.Great price for 2 very useful double-plug outlets! But...USB ports (2 on each outlet) are always on. Why?Setup can be tricky - remember to name each controllable component uniquely (eg. Outlets A & Outlet B; Switches 1a,2a,1b,2b).Each outlet can be controlled (on/off) as one device, *and* each switch (power plug) can be controlled separately.Google Assistant/Google Home controls them perfectly once you understand the component name/label setup."Ok, Google. Turn on Outlet A.""Ok, Google. Turn off Switch 2a."We had a hard time getting my wifi to discover this plug. Once it finally connected, it was quick and easy to get it connected and working with Alexa.Instructions are difficult to follow and QR code does not work site would never connect. Had to go to app store to download Homesmart app. Cannot use both plugs individually with Alexa you must use app.My daughter and her roommate love this. No looking for a remote and both can control their dorm fairy lights. Still room to charge electronics tooAfter about 2 months of use, one of the outlets started making a weird, buzzing noise like exposed electricity. I unplugged it for a day, then plugged it back in and it started buzzing again after about an hour. The other one works fine, so I wish I could just get this one replaced.Tu ingenio es lo único que te va a limitar en los usos que le puedes dar. A nosotros nos sirvió mucho, ya que necesitábamos instalar tres circuitos independientes de escalera. Solo conectamos la línea de los focos a los contactos y por comandos de voz o usando la app, los controlamos, práctico a más no poder. El único problema y del cual nos dimos cuenta apenas, es que él contacto de la izquierda, tiene la polaridad invertida, el neutro es el vivo y el vivo es el neutro, ojalá avisen para cambio físico, ya que es un error de ensamblado y creo que todos han de estar así.
