Shelly Plus 1 | WiFi & Bluetooth Smart Relay Switch| Home Automation| Compatible with Alexa & Google Home| iOS Android App| No Hub Required| Wireless Switch| DIY Remote Control Garage Door

Used this to control my vivarium light, mainly through alexa but also with my phone. I did a bit of research because I wasn’t sure if you needed to wire a manual switch for it to work (you don’t). Wiring is fairly straight forward without including a switch. Had a few problems pairing it to the app but that could well have been user error. Once I’d got it connected, added the alexa skill, paired my Shelly account and it works flawlessly. Can’t comment on reliability yet but it appears to be good quality. Would have been cheaper to just put an inline switch in but who doesn’t love a gadget.

These are simply extraordinary pieces of engineering, packing a very powerful punch. Not only can you use these to switch devices in or off- mains or dry contact- but the switch function can also be used to sense. Mine are fast and reliable, much more so than Z-wave devices. Programming can be performed by WiFi or Bluetooth to set operation parameters or even macro-like event programming. For example, set up as a momentary switch, one push can initiate a sequence of events including timings. You can also connect to them via the cloud from a browser or even CarPlay- useful for opening gates, doors, or other functions. Absolutely amazing devices for the money.

I have loads of Shelly gear which I use to automate lights and also my electric gates!So easy to install and run, no hub needed as they connect directly to my wifi.Can make existing lights smart without upsetting the current eco system. I have even used these on my electric gates to turn a dumb electric gate smart!I love these things.

Used to open a liftmaster gate via the Shelly app, which integrates with Home Assistant. Removing the need to use the expensive and limited functionality of the MyQ app.

They work and with HA so I'm happy - I've now purchased other Shelly devices.

Unfortunately one of the two units was faulty and would not connect through either my Wi-Fi or Bluetooth device, it was the first one that I tried, I swapped the second unit in and everything worked fine straight away. There is no easy way to return just one , so for this reason I would not buy a twin pack again. In the UK returns are by UPS for this product as it has to go back to Europe, very annoying as the nearest drop off point for me is 8 miles away, lots of paperwork and huge printed labels. The unit is neat and compact and the one that was not faulty functioned as expected and was easy to set up on my phone and the system generally works very well and integrated with Alexa quite easily. The terminals are very small and I found that two 1mm copper wires were a rather snug fit. Given that one was faulty and the returns process was annoying, I can only manage 3 stars which is sad because I like this product and am considering buying more, slightly worried by the reports of faulty units in reviewer though. Test on the bench if possible before installation.
