Shelly 1 Mini Gen3 - WiFi & Matter Smart Switch Relay, 1 Channel, 8A, Home Automation, Dry Contacts, Garage Door Remote Control, Compact Size, Alexa and Google Home, iOS & Android App, No Hub Required

I use a lot of Shelly relays and always have. These new Gen3 relays are fantastic bits of kit. As the world is getting smarter especially with smart home technology I have customers always asking me if there’s a way they can switch something by WiFi or a way to make Alexa turn they’re outside lights on etc. with Shelly relays the possibilities are pretty much endless for me as an electrician. Customers love them and they’re a breeze to install and setup. The WiFi connectivity works extremely well however if you’re hiding them in a backbox, junction box or in a loft etc anywhere that’s quite out the way from the customers WiFi you may need extenders / access points to ensure a good solid connection.

Incredible little device. I used it to turn a non smart EV charger into something that can be scheduled to come on during my cheap charging tariff. It's easy to set up, in my case I've set a schedule and I don't need to access it directly unless I need to turn it on to charge outside those hours. You need to know what you're doing and it's NOT for the high voltage lines, just the low voltage communication ("car is connected") line. Plenty on the internet if you plan to do the same but if you don't know what you're doing, DON'T DO IT!

Does exactly what it says, easy to setup and once setup in the shelly app, after you have created an account, download the skill into Alexa and hey presto!! Very compact, I wondered if they would actually work since the wall light is all metal and effectively due to the metal back box the shelly was mounted inside a metal cage but it still works great.

This fitted what I wanted to a tee.... A tiny little box that is so small, when installing I dropped it and it fell behind the radiator and I had fun trying to retrieve it. This is my second Shelly device and I think it's great. I like their app and the integration with Home Assistant. The downsides. I don't understand why there are so many terminals for such a small device. You need to add a Live to the unit, then a separate Live that will power your devices and then a third live that is used for the switch line. This meant that I had 3 Wago boxes in the tiny light blackbox. I understand this when it's in a pro unit that goes into your consumer unit but maybe not for a single bulb and switch. HomeKit support could be better from Shelly although it seems some devices are now getting supported with Matter. Overall a great device that worked first time and is so small it fitted into my back box, even with 3 Wago junction boxes in there!

Genius bit of kit. If you're into automating your home and can do a bit of wiring, then these Shelly 1 Minis are absolutely superb. I'm using Home Assistant, so these Shelly devices are fully integrated into my home. I got them up and running in no time at all. I'm a little bit sceptical of the claim that they can fit behind any switch or socket, but if you've got a reasonably deep back box, it should be ok. So far, they've been solidly reliable, with great connectivity and no drop outs. I'm just waiting for my Shelly Uni Plus to arrive now, so that I can integrate my old analogue burglar alarm into my IoT smart home.

Small, simple to wire and automates lights quite simply! As a non-electrician I found it quite simple to wire behind my outdoor lights. The instructions weren’t so great so went on the internet to find how to ho the light up when I didn’t want it to connect to a standard light switch. Once wired correctly the app quickly identifies it and can connects it. The user interface of the app is not straightforward but can be figured out. I just can’t believe something of this size does all of that wirelessly without an additional hub like Hive needs.

Worked a treat turning our outdoor Christmas decorations on and off by using Alexa. Easy to connect to home wifi network, works in low temperatures, so okay to install in outdoor electrical enclosure in range of house wifi. Only downside instructions not quite clear on wiring up the cables to the correct terminals. Had to seek further diagrams online.

These are my go to product quality is good easy to use integrates with everything. Coupled with Home Assistant you can do anything these are just Brilliant brilliant brilliant brilliant!

Ich habe den Shelly 1 Mini (Gen3) in mein DIY-Smart-Home-Projekt integriert – ein selbstgebauter ESP32-basierter Smart-Wecker mit WLAN, Display und Licht-Zeit-Steuerung. Der Shelly lässt sich ganz einfach per fester IP über HTTP-Befehle vom ESP32 ansteuern. Die Integration war problemlos: Ich konnte das Licht im Haus per Zeitplan automatisch ein- und ausschalten – direkt über meinen Mikrocontroller. Was ich besonders gut finde: ✅ Kompakt und passt in jede Unterputzdose ✅ Funktioniert zuverlässig mit fester IP im Heimnetz ✅ Steuerung auch über die offizielle App möglich – ideal für manuelle Eingriffe ✅ Schnelle Reaktion, einfache Einrichtung Perfekt für alle, die ESP32-Projekte mit smarter Lichtsteuerung kombinieren wollen. Klare Kaufempfehlung für Maker, Bastler & Smart-Home-Fans!

First of all, this is a really useful device. Very small so that you can install it inside an existing outlet-box and very easy to integrate into your HomeAssistant application (or just use their app!) My only complaint was that when I tried following the wiring "schematic" that was included with the device, it shows that your light/appliance connects to the Neutral wire (white, in the USA) from the "I" (input) screw. This never worked for me and I thought I just had a dud (bad Shelly). Actually, the "I" is for "input", not output or "neutral". (who would have guessed?) I found the correct wiring diagram on YouTube channel "The Hook Up". I created my own version with pictures of sample components (apologies for some rough lines!) and I'm attaching it to this review. I'm not a licensed electrician (and I don't think the guy from "The Hook Up" is either) so proceed at your own risk, but if you try and fail using the schematic that comes from Shelly, before you return the device or toss it in the trash, you might want to try this wiring...

a very high-quality smart home element
