If:
pairing your Shelly Wi-Fi device via the Shelly Smart Control app fails (and you haven't found the solution in the Shelly Wi-Fi Troubleshooting Guide),
ORyou want to use your Shelly Wi-Fi smart device without the app or Shelly's cloud (e.g., connected to Home Assistant or another local hub, or used standalone in local mode),
then read this guide, which explains how to connect the device to your Wi-Fi network using its built-in web interface.
Two-Step Pairing via the APP:
Pairing a Shelly device using the app is a 2-step process:
In the first step, your phone connects directly to the device, and sets it up to join your Wi-Fi network.
After this is successful, in the second step, the app discovers the device on your local network and adds it to your Shelly cloud account.
Note: At the end of the process, you can choose whether to use the device in cloud mode or without cloud, and you can also disable cloud access later in the Shelly Smart Control app if you prefer local-only operation.
Pairing via Web Interface (Local Setup)
All Shelly Wi-Fi devices include a built-in web server, so connecting to Wi-Fi (and essentially all other configuration) can also be done through a local web interface.
Steps:
Reset the Shelly device to factory default state.
You’ll find instructions in the user manual of your device. (Typically, this involves holding down the pairing button for about 30 seconds.)On a phone or PC, open Wi-Fi settings and look for a network broadcast by the Shelly device in pairing mode.
Its SSID will look like this:shellyxxxxx-78d345.Connect to this Wi-Fi network with your phone or PC.
(Note: there will be no internet access, since you're connecting directly to the device, which isn't yet connected to your router.
If a pop-up warns you about no internet, accept it and stay connected.)Open a web browser, and go to:
https://192.168.33.1/
This is the default IP address of every Shelly device when in pairing (AP) mode.You will see an interface similar to what appears in the Shelly Cloud app for managing devices.
Click the INTERNET / SECURITY icon to access the network settings.
Under the WI-FI CLIENT section, enter the SSID and password of your local Wi-Fi network.The device will restart and connect to your Wi-Fi network.
(After this, it will no longer be accessible via192.168.33.1, because it will receive a new IP address from your router, unless you assigned a fixed IP.)
Next steps depending on your use case:
If you want to use the device in local mode:
You're all set!
You can now access the device’s local web interface at the new IP address assigned by the router (or the static IP you set).
If you want to use the device with the Shelly Cloud:
Open the Shelly Smart Control app, tap the plus (+) button in the bottom right corner, and select “Scan Network” to search for devices already connected to your Wi-Fi.
Once discovered, add the device to your Shelly Cloud account.
This method is particularly useful for power users, those who rely on local control (e.g., via Home Assistant), or for troubleshooting failed in-app pairings.
