Apple Home, Google Home or Home Assistant can't add your Shelly over Matter, or it adds and shows No Response. Usually it's the pairing window or IPv6.

What are you seeing?
Pick the closest match and we'll point you to the fix most likely to sort it.
Gen4 Shelly devices come with Matter turned on. To add one, your phone finds it
over Bluetooth and passes it your Wi-Fi details. From then on your hub talks to
it over your home network, using IPv6.
Pairing can fail at any of those points: the device has stopped offering itself
for pairing, the phone is on a different network, or the network doesn't carry
what Matter needs. The device's web page shows the first of those straight
away.
Before you start
Every fix here is done in your Matter app, a browser or your router. Gen4 Shelly devices run Matter over Wi-Fi, so they need 2.4 GHz Wi-Fi and no Thread border router. Don't open the wall plate to read a label; ask your electrician.
Quick checks first
Run these checks before moving on to the fixes.
Checklist0 of 4 checked
Check it's on your Wi-Fi
The LED on the back is on solid once the device has joined your Wi-Fi.
Put your phone on home Wi-Fi
Turn off mobile data while you pair, and join the same network as the Shelly and your hub.
Check you have a Matter hub
Matter needs a controller. Shelly names Apple TV 4K, Amazon Echo 4th gen or newer, Samsung SmartThings Hub and Google Nest Hub 2nd gen.
Check the Matter page
On the device's web page, open Matter from the menu. It shows whether Matter is on and whether the device is ready to pair.
Fixes, most likely first
Work down the list and stop when it's fixed.
1
Most likely for you
The pairing window has closed
How to tell. Your Matter app never finds the device. Its web page says the commissioning window is expired, which Shelly says happens after a timeout.
Restart the device
Open Matter from the device's web page menu. Under the message "Commissioning window is expired", click Reboot.
Pair straight away
Once it's back up, scan the code in your Matter app straight away, before the window closes again.

2
Most likely for you
Your phone isn't on the same network
How to tell. Pairing starts, then fails. Shelly says the phone, the hub and the device all need to be on the same network while it pairs.
Join the Shelly's network
Turn off mobile data and connect your phone to the Wi-Fi the Shelly is on, not a guest network.
Stand close to it
The phone starts pairing over Bluetooth, then hands the device over to your Wi-Fi. Keep the phone near the device until it's added.

Most likely for you
IPv6 is off on your router
How to tell. The Shelly app works, but your Matter app shows No Response. Matter talks to the device over IPv6 once it's paired, and IPv4 alone isn't enough.
Check the device has an IPv6 address
On the device's web page, go to Settings, then Wi-Fi. Under IPv6 addresses, look for one starting with fd, or with your internet provider's prefix.
Turn on IPv6 in the router
In your router's settings, find IPv6, often under WAN or Network, and turn it on. Shelly says you don't need IPv6 from your internet provider. Local addresses are enough.

Most likely for you
The router filters Matter's traffic
How to tell. It pairs, then drops out after a few minutes, usually on mesh or business-grade Wi-Fi with separate networks for different devices.
Keep it on one network
Keep the Shelly, the hub and Home Assistant on the same network. Shelly and Home Assistant both say Matter can fail across VLANs.
Turn off multicast filtering
Shelly names IGMP snooping, multicast filtering and multicast to unicast as settings that break Matter on networks like UniFi. Turn them off for the network your Shelly devices use.

Most likely for you
Matter is turned off
How to tell. Its web page shows Matter isn't enabled, or the device was switched to Zigbee with five quick presses and has left your Wi-Fi.
Turn Matter on
Open Matter from the device's web page menu. Tick Enable and click Save and reboot.
Switch it back from Zigbee
Hold the button for 5 seconds to turn its hotspot on, join it, and open 192.168.33.1. Go to Settings and click Switch to alternative firmware.

Most likely for you
The hub or app isn't ready
How to tell. You can't find an option to add a Matter device, or Home Assistant says Matter is unavailable.
Open Add integration
In Home Assistant, go to Settings, then Devices and services, and tap Add integration.
Pick Matter
Search for Matter and tap it. On Home Assistant OS it installs the Matter Server app with it.
Use the companion app
Home Assistant says you can only add a new Matter device from the Home Assistant app on your phone, not from a browser.
Give Google Play Services time
On Android, Home Assistant says the Matter parts of Google Play Services can take up to 24 hours to arrive.

Most likely for you
You can't find the setup code
How to tell. There's no QR code to hand. Shelly prints it on the device label, and shows it in the app and on the device's web page.
Read it on the web page
Open Matter from the device's web page menu. While it's ready to pair, the page shows the QR code and the 11-digit manual code.
Photograph it for next time
Home Assistant suggests a photo of the code, since you need it again after a reset.

Shelly Presence Gen4It shows one zone by default
Choose how many zones to share
Shelly says the Presence Gen4 shows one room zone in Matter to start with, and up to ten. Set the number on its Matter page.
