Connecting Shelly Gen4 devices to Google Home, Alexa and Apple Home
Your devices are already installed and showing in the Shelly Smart Control app. Now you can add them to your voice assistant and to the smart home app you already use. Here are all three routes, step by step, with no technical background needed.
For Shelly Gen4 devices
No access to the electrical panel needed
Google Home
Link your Shelly account once, and every device in the account comes across together.
Amazon Alexa
Enable the skill and link your account. You can start from either of two apps.
Apple Home
A direct Matter connection, one device at a time. A hub (HomePod or Apple TV) is recommended.
1. Before you start
Four checks in the Shelly Smart Control app that prevent most problems later on.
Make sure the device appears in the app and shows as “Online”. A disconnected device won’t appear on any of the platforms.
Update the firmware if the app offers an update. Some features are only available from certain firmware versions.
Check that the “Cloud” setting is turned on for the device. Control from Google Home and Alexa goes through the Shelly cloud, so if the cloud is off, the device simply won’t be found.
Give each device a short, clear name and assign it to a room, such as “Lights”, “Water heater” or “AC”. That name is what you’ll say in voice commands, so technical names like “Shelly 1PM-A4” make it harder to recognize.
2. Connecting Shelly to Google Home
Account linking: link your Shelly account to Google once, and all the devices in the account come across together.
Open the Google Home app on your phone.
Tap “Devices” or “+”, choose “Add” and then “Works with Google”. In some versions of the app the path is “Settings” and then “Works with Google”.
In the search field, type “Shelly Smart Control” and select the result.
The Shelly sign-in page opens. Sign in with the same account your devices are registered to and approve the permissions.
When linking is complete, the list of devices found is displayed. Assign each one to a room and tap “Done”.
Test it: turn a device on and off from Google Home, then by voice: “OK Google, turn on the kitchen light”.
That’s it. Linking is a one-time step. Any new device you add to the Shelly app later appears in Google Home only after “Sync devices”, or after you say “OK Google, sync my devices”.
3. Connecting Shelly to Amazon Alexa
This is account linking too. You can start from the Shelly app or from the Alexa app. The result is the same, so pick one.
Option A: from the Shelly app
In the app settings, choose “Integrations” and then “Amazon Alexa”.
Tap “Enable skill”, sign in with your Amazon account and approve the link.
Option B: from the Alexa app
Go to “More”, then “Skills & Games”, and search for “Shelly Smart Control” (on older accounts: “Shelly Cloud”).
Tap “Enable to use”, sign in to your Shelly account and approve.
Both routes end with the same step: run a device search, either “Discover devices” in the app or the command “Alexa, discover devices”. When it’s done, the number of devices found is displayed.
Scenes set up in the Shelly app also come across to Alexa after the device search, and you can run them by voice or include them in Routines.
4. Connecting Shelly to Apple Home with Matter
A different route: no account linking and no skill. Each Gen4 device joins your Apple home directly through the Matter standard, one at a time. Using Home Assistant? See connecting Shelly to Home Assistant.
Hub: recommended, and required for control away from home
Since iOS 18, you can add a Matter device and control it from your iPhone even without a hub. For control away from home and for automations, you need a hub: a HomePod or Apple TV. Shelly and OZZI don’t supply hubs. All Gen4 devices are Matter certified, so there’s nothing to prepare on the device side. On Gen3 devices, turn on Matter first, following the Shelly and Matter guide.
Make sure your phone is connected to your home Wi-Fi network (the same network as the device, and as the hub if you have one), and that Bluetooth is turned on on your phone.
Open the Home app on your iPhone or iPad, tap “+” in the corner and choose “Add Accessory”.
Scan the Matter QR code. On Gen4 devices the code is printed on the packaging, and there’s also a sticker you can put on the device itself. It’s a good idea to stick it on before the device goes into the wall.
If you no longer have the packaging, open the device’s web interface (WebUI), go to the “Matter” tab and get the QR code from there.
Continue with the usual Apple Home process: choose a home, assign a room, give it a name and set the accessory type, such as light, switch or outlet.
Repeat steps 17 to 20 for each device separately. Matter has no bulk import of the whole account.
Once connected, the device is available in both places at the same time: in the Home app and in the Shelly Smart Control app. There’s no need to remove it from either.
5. What each platform gets
The practical difference between the three routes.
All three platforms get the basic functions: on and off, dimming, shutter position and sensor readings. Energy-use analysis, tariffs, reports and measurement history stay in the Shelly Smart Control app. Matter currently exposes only basic power measurement.
6. Troubleshooting
The five most common problems, in the order worth checking.
The device doesn’t appear after linking
Check that it’s Online in the Shelly app, that Cloud is turned on for it, and that you signed in with the same account it’s registered to.
A new device wasn’t added automatically
Add it to the Shelly app first, then run “Sync devices” in Google Home or “Discover devices” in Alexa.
It worked, then suddenly stopped
Changing your Shelly account password silently breaks the link. Unlink and link again with the new password.
The voice assistant doesn’t understand the name
Change it to a short, unique name (one word is best), and make sure no two devices have similar names.
Apple Home can’t find the device
Make sure your phone (and the hub, if you have one) is on the same Wi-Fi network as the device, that Bluetooth is on on your phone and that the device has the latest firmware. If the device was previously paired with another home, remove it from there before pairing it again.
7. Frequently asked questions
What customers ask us before and after connecting.
How do I connect Shelly to Google Home?
Open the Google Home app, choose “Add” and then “Works with Google”, search for “Shelly Smart Control” and sign in with your Shelly account. All the devices in the account come across in one go. Full details are in section 2.
Does Shelly work with Apple Home?
Yes, through the Matter standard. All Shelly Gen4 devices, and some Gen3 devices after a firmware update, support Matter and connect directly to the Home app. A hub (HomePod or Apple TV) is needed for control away from home. Plus models and Gen1 devices don’t support Matter. See Shelly and Matter.
Why doesn’t Shelly show up in Alexa?
In most cases the “Cloud” setting is turned off for the device, or you signed in with a different Shelly account from the one the device is registered to. Once that’s fixed, say “Alexa, discover devices”.
A new device I added doesn’t show up in my voice assistant. What do I do?
Syncing isn’t automatic. Add the device to the Shelly app first, then run “Sync devices” in Google Home or “Discover devices” in Alexa. In Apple Home, scan the new device’s QR code.
Can the same device be connected to several platforms at once?
Yes. A device can appear at the same time in Google Home, Alexa, Apple Home and the Shelly Smart Control app, and control from any of them updates all the others.
Does energy-use data come across to the voice assistant?
Only partly. The basic functions come across, but consumption analysis, electricity tariffs, reports and measurement history stay in the Shelly Smart Control app, which is where you actually manage your energy savings.
What happens when the internet goes down?
Google Home and Alexa work through the Shelly cloud, so they stop responding. A Matter connection to Apple Home runs locally on your home network and keeps working, and so does the physical wall switch.
Voice control is a convenient layer on top of the system, but it depends on the internet and the cloud, so for critical actions it’s better to stick with the app or the physical switch. Managing electricity use, the smart meter, the smart switches and savings reports all continue in Shelly Smart Control.
