Shelly1 PM Relay Switch, WiFi Smart Home Automation, Compatible with Alexa & Google Home, iOS Android App, No Hub Required, Wireless Light Switch, Smart Appliances Gadgets, UL

This is pretty simple to Install, and has great features. You can use it for anything.One con is it is not very easy to fit in the switch box. It's pretty small but if you have a lot of wires stuffed in there it is difficult.I love that the switch still works. I have it on an outdoor light, and the light turns on at dusk and off at 1 AM. That's the automatic part. The switch allows it to still be turned on or off. If it's off, taking the switch to On will turn it on. And then you can turn it back off, or, if you leave the switch On, it will turn off based on the programming.

Switch was very easy to setup. Works very well. Wiring diagrams are not very clear, so make sure you understand that before wiring it up. Very responsive and very reliable. Paired these switches with a couple of Shelly Motion Detectors and Home Assistant. Love the fact these stay off a corporate cloud and remain in my full control.

I have a couple of these. I watched a few YouTube video ls thinking that would be the easiest way to learn how to use this, but honestly, the diagrams on their site are more helpful.My setup is the shellys for use with siri. I tried this with homebridge. That worked for simple setups but it didn't work for my three way switch. Siri could turn the switch on but not off. So I flashed these with a homekit compatible firmware and they work flawlessly now.It was fairly straightforward. I can imagine lots of uses for these, but I won't be giving any to my non handy brother. He'd never get it to work. If you are comfortable tinkering with things it's a great product. If you want to just wire it in, scan a qr code and it all just works, then it's not the product for you.

This shelly 1PM (power monitoring) smart relay is a really fantastic device. It allows you to make a number of dumb devices smart, without having to spend a lot of money replacing switches etc...Even though this is not generally advertised, the Shelly relays can be modified (via the internet) to work perfectly with homekit...Some very smart person has been incredibly generous to not only develop the code, to flash these relays, so that they work with homekit. They have extended that generosity to uploaded instructions (and even a video) outlining exactly how to do that process...There are cheaper smart relays out there. However, I have used them and they have a high failure rate...I have quite a few Shelleys in my house, controlling; lights, fireplace, fans, heaters etc etc. I definitely recommend considering them if you want to go that step further into the smart home realm!

There's no way the screw terminals could support 1800 watts with the wire size they allow. I'm using this with 18 gauge wire (Think 'Drop Cord' size wire), pulling about 200-250 watts AC, and I haven't had a problem. WiFi is solid, API/JSON is great to work with, very well documented. Major drawback is physical connection limitations (wire size). Will buy again when the need comes up.

Once I got my Shellys though the setup process, they have worked great--all 8 of them that I got. I would give an enthusiastic 5 stars if the setup went like it was supposed to, but that's what I'm here to warn you about:My issue was with the setup. The process calls for using the app on your smartphone with your smartphone connected to the Shelly as a WiFi Access Point. What they don't tell you in the instructions is that your phone or tablet still has to be connected to the Internet simultaneously to being connected to your Shelly via WiFi. You obviously don't have Internet though the WiFi while connected to the Shelly, so unless the device has a data plan you have to get creative. No matter how hard I tried, I couldn't get through the setup process without the simultaneous connection to the Internet.Compounding the problem is that the Shelly app absolutely refused to do the setup process on my iPhone running the new iOS13 released a couple of weeks ago. It never gave me the opportunity to enter my WiFi SSID & password, therefore the Shellys could never connect to my network. Perhaps it would have worked with iOS13 if the device FW worked better? Who knows, but that leads me to the FW issue:All 8 of my Shelly 1pm devices came with an old version of FW that barely worked even once they were set up. Luckily the old FW worked just well enough to let the Shelly app update them to the latest FW.What FINALLY worked for me: 1) Wired up the Shelly to power and a light. I would recommend doing this with a temporary setup at a table using a power strip, bulb, and light switch. If you have any difficulties with setup, you don't want to be standing at the wall box doing all of this. 2) I used my old iPhone 7 still running iOS12. Since that phone doesn't have a data plan, I set up reverse-tethering through my MacBook Pro to get an Internet connection via Bluetooth (google it if you need to). Again, the initial set-up process simply wouldn't work without your phone/tablet connected to the Internet by some method other than WiFi because that is connected to the Shelly's access point. 3) Once the Shelly is on your network, you can put your phone back on your network WiFi and let the app update the FW in your Shelly. 4) I think the Shelly Cloud also has some bugs during the initial setup process. I was able so set up most of my 8 Shellys quickly once I figured out all those workarounds, but a couple of them were still stubborn about getting set up. I just had to try over and over for a couple of hours until the Shelly Cloud made it through the process. 5) After all that, I then did the "easy" part of wiring the Shellys into my light switch boxes.Once I had my Shellys on my network and got their FW updated, they have been working reliably with my new phone running iOS13--no problems with either the app or Shelly Cloud. It's the setup that's buggy due to a combination of factors: a) at the time of writing the Shelly app running on iOS13 won't do the setup process; b) whatever phone or tablet you use to do the setup has to have a data plan or be connected to the Internet via something other than WiFi; c) the version of FW shipping with the batch of my 8 Shellys barely worked; and d) Shelly Cloud was unreliable when doing the setup process.FYI, in desperation I had my friend come over with his Samsung Galaxy and that didn't work for the setup process either. The only thing that worked for me was an iPhone running iOS12.Again, now that I've made it through the pain of the setup, the Shellys and Shelly Cloud have been working great. I have them integrated with Home Assistant using JSON commands, and that works reliably. I could now disconnect my devices from the cloud and Home Assistant can still control them directly.

Install this above the light in our kitchen, worked with our existing three way switch setup. Integrated with google assistant easily.

I got this for a smart water heather project, so far so good, work with Alexa, Google home, Smarthings, thx to this save me to buy a step down transformer for other smart plugs to control my contactor, is just what I was looking for and save me few $$$, the app for android is great, seems like you can add some sensors.

Tengo un mes usándolo y hasta ahora funciona muy bien; sin embargo me tomó bastante tiempo la configuración, hay que ser paciente e intentarlo varias veces.
