Product description

Shelly 2PM Gen4 (the Device) is a Matter-compatible small form factor 2-channel smart switch with power measurement and cover control. Equipped with a multi-protocol wireless MCU, it supports Zigbee and Bluetooth connectivity for a secure connection. The Device can control 2 electrical circuits, including a bi-directional AC motor, motorized blinds, Venetian blinds, and roller shutters. Each circuit can be loaded up to 10 A (16 A total for both circuits) and its power consumption can be measured individually (AC only). The Device can be retrofitted into standard electrical wall boxes, behind power sockets and light switches, or in places with limited space. The Device has an embedded web interface to monitor, control, and adjust its settings. The web interface is accessible at http://192.168.33.1 when connected directly to the Device access point or at its IP address when accessed from the same network. The Device can access and interact with other smart devices or automation systems if they are in the same network infrastructure. Shelly Europe Ltd. provides APls for the devices, their integration, and cloud control. For more information, visit https://shelly-api-docs.shelly.cloud. ® The Device comes with factory-installed firmware. To keep it updated and secure, Shelly Europe Ltd. provides the latest firmware updates free of charge. Access the updates through either the embedded web interface or the Shelly Smart Control mobile application. Installation of firmware updates is the user’s responsibility. Shelly Europe Ltd. shall not be liable for any lack of conformity of the Device caused by the failure of the user to install the available updates in a timely manner.

Installation instructions

• To connect the Device, we recommend using solid sin- single-core wires or stranded wires with ferrules. The wires should have insulation with increased heat resistance, not less than PVC T105°C (221°F)
• Do not use buttons or switches with built-in LED or neon glow lamps. When connecting wires to the Device terminals, consider the specified conductor cross-section and stripped length. Do not connect multiple wires into a single terminal.
• For security reasons, after you successfully connect the Device to the local Wi-Fi network, we recommend that you disable or password-protect the Device AP (Access Point).

In Dual input mode, the Device supports Slat control that allows for precise adjustment of slats in Venetian blinds.

This function has the following settings

• Open time – the duration in seconds for the slats to transition from fully open to fully closed position.
• Close time – the duration in seconds for the slats to transition from fully closed to fully opened position:
  • Default: 1.5 seconds
  • Accepted range: 0.5-10 seconds
• Step – controls the incremental movement of the slats in percent between the two endpoints:
  • Fully closed position (0%)
  • Fully opened position (100%)

Button input configuration

• Pressing a button when the cover is static: Moves the slats in the corresponding direction by the predefined step.
• Pressing the button for the same direction while the cover is moving: Stops the cover.
• Pressing the button for the opposite direction while the cover is moving: Reverses the cover movement until the endpoint is reached.
• Pressing and holding the button moves the slats and the cover in the corresponding direction until the endpoint is reached.

Switch input configuration

• Turning the switch on: Moves the slats and the cover in the corresponding direction until the endpoint is reached.
• Turning the switch off: Stops the cover movement.
• Both switches turned on: The Device respects the last engaged switch. Turning off the last engaged switch stops the cover movement, even if the other switch is still on. To move the cover in the opposite direction, turn the other switch off and on again. In Detached mode, the Device can only be controlled through its web interface and its app. Buttons or switches connected to the Device will not control the motor rotation.

To use the Device in Detached mode, connect it as shown in Fig. 2a):

1. Connect the two L terminals to the Live wire and the N terminal to to the Neutral wire.
2. Connect the common motor terminal/wire to the Neutral wire
3. Connect motor direction terminals/wires to the 01 and 02 terminals.

Obstacle detection
Shelly 2PM Gen4 can detect obstacles. If an obstacle is present, the cover movement stops. If configured in theDevice settings, the movement changes its direction until the endpoint is reached. Obstacle detection can be enabled or disabled for one or both directions.

• The Device outputs can be reconfigured to match the required rotation direction.
• Interaction with the button, the switch, or a control in the Web Interface or in the App (has to command the cover in the opposite direction to the direction before the safety switch engagement).

Adding Zigbee Device

• To switch the Device from Matter firmware (default) to Zigbee, press 5 times the Reset button. The Device stays in pairing mode for 2 minutes, and you can find it in your home automation platform through the Zigbee Hub. If you cannot find the Device, press the Reset button 3 times.
• To remove the Device, go to its page and delete it from your home automation platform. OIn Zigbee mode, the AP of the Device is not available by default. To enable it, the you should hold the Reset button for 5 seconds.

Setting up the Device via Matter
Before you start, make sure you have:

• 2.4 GHz Wi-Fi network
• A Matter-compatible hub connected to the Internet
• A mobile device with Bluetooth enabled and a Matter-compatible app installed

1. Enable the access point of the Device by pressing and holding the Reset/control button for 5 seconds.
2. Scan the Matter QR code inside the box.
3. Follow the instructions that appear on your screen to complete the process.
   • Keep the QR code for future reference. If you reset the device, you will need that code again.
