Typically, this involves connecting the neutral (N) and line (L) wires to the corresponding terminals on the Shelly device, and the motor's control wires to the output terminals (O1 and O2).​

   • Mounting: Place the Shelly device in a suitable enclosure near the window motor, ensuring it's protected from environmental factors.​

   • Power On: Restore the main power supply.

The wiring is shown in the diagram below:

Here are actual pictures of the wiring from several angles

Prior to the actual calibration itself, set the Idle motor settings according to your conditions to assure proper calibration.

This screenshot below is informational and shows the error if the idle settings were left by default and the calibration is failing.

Start the actual calibration - keep in mind that this might take several minutes and the window might close and open several times during the process. Let it finish until you see its done.

Once the calibration is complete, you will get the controls in the device web interface like on the screenshot below. Keep in mind that based on device used and FW, the looks might differ a bit.

If required, reverse direction of the buttons to make sure the physical button pushed accommodate your preference for the directions.

To avoid accidental device reset, disable the “Enable factory reset from input“ checkbox.

6. Add Shelly BLU RC Button 4 as a BT Home component
   Make sure BT module is turned on, on the Shelly 2PM Gen3 to add Shelly BLU RC Button 4 remote to BT Home

Press the pairing button on the Shelly BLU RC Button 4. The devices should appear in the list of discovered devices. Then click Add button.

This is how the newly added device will look like in the web interface

And this is how it will appear on the Home section.

In order all device buttons/entities to appear, press any button of Shelly BLU RC Button 4 so the populate in the view.

7. Set Up Automation and Schedules

You can create local action to control and automate the electric window.

Create local action for window opening

Create local action for window closing

Troubleshooting Tips

• Device Not Responding: Ensure the Shelly device is properly wired and receiving power. Check your Wi-Fi network for connectivity issues.​

• Calibration Issues: If the window doesn't operate as expected, redo the calibration process to ensure accurate open and close positions.​

• Remote Pairing Failures: Ensure the Shelly BLU RC Button 4 is within the effective Bluetooth range and has functional batteries.​
