How to set up the Wi-Fi and update the firmware of several Shelly 2PM

Of course, here's a manual for setting up and updating the firmware of the Shelly 2PM using the Sit-IoT app:

1. Download and installation:

Download the Sit-IoT app from the Google Play Store.
Install the app on your mobile device.

2. Connecting to the Wi-Fi network:

Open the Sit-IoT app and log in.
Make sure your mobile device is connected to the Wi-Fi network you want to connect the Shelly 2PM to.
In the app, go to "Add new device".
Verify that the app shows the correct Wi-Fi network.
Enter the Wi-Fi network configuration parameters, including the network name (SSID) and the password.
Optional: You can set up additional options such as a static IP, enable the access point or connect the Shelly in extension mode.
Optional: If you want to use an MQTT broker, you can set it up in this section.

3. Automatic setup:

In the "Add new devices" section, start the automatic setup.
The app will automatically search for and set up the Shelly devices within range.
Wait for the app to finish setting up all the devices.

4. Firmware update:

Once the devices are set up, go to the "Device status" section.
Check whether a new firmware version is available.
If an update is available, click "Update".
Wait for the firmware to download and install.
The device will restart automatically after the update.

5. Advanced settings:

In the "Advanced settings" section, you can change the device name, the Wi-Fi settings and access the built-in web server.
You can check the Wi-Fi signal strength and change the network if necessary.
You can also perform a factory reset or restart the device.

6. Enabling the cloud:

Once you've set up and updated the firmware of your Shelly 2PM, you can enable the cloud with the Shelly app.
This will let you control your device remotely and create scenes.

Additional tips:

Make sure the Wi-Fi signal is strong enough for the Shelly 2PM.
Avoid connecting the device to networks with a weak signal (shown in red in the app).
If you have trouble connecting or updating the device, try restarting it or resetting it to factory settings.

Congratulations! You've successfully set up and updated your Shelly 2PM using the Sit-IoT app. Now you can enjoy all the features this device offers.
