Short Description
The Shelly Wave Pro 2 is a DIN rail-mounted, 2-channel smart switch with potential-free contacts. It controls two independent electrical loads up to 16 A per channel (25 A total). It supports both switches (default) and push-buttons.
Switch connected to input terminal SW (SW1)
If SW (SW1) is configured as a switch (default):
- Single toggle: Changes output O (O1) state to opposite (on/off/on...) and sends command to associated devices in groups 2 and 3 (see Z-Wave Association).
- Double toggle (within 500ms): Interpreted as a double press; sends command to dimmers, shutters, etc., in groups 2 and 3.
Switch-memory connected to input terminal SW (SW1)
When SW (SW1) is set to switch-memory mode:
- Closing contact: Sets output O (O1) to ON and sends command to devices in groups 2 and 3.
- Opening contact: Sets output O (O1) to OFF and sends command to devices in groups 2 and 3.
Push-button connected to input terminal SW (SW1)
When SW (SW1) is configured as a push-button:
- Short press: Toggles output O (O1) state and sends command to devices in groups 2 and 3.
- Hold: Sends command to devices in group 3.
- Release: Sends command to devices in group 3.
Switch connected to input terminal SW2
If SW2 is configured as a switch (default):
- Single toggle: Toggles output O2 state (on/off/on...), sends command to devices in groups 4 and 5.
- Double toggle (within 500ms): Interpreted as a double press; sends command to dimmers, shutters, etc., in groups 4 and 5.
Switch-memory connected to input terminal SW2
When SW2 is set to switch-memory mode:
- Closing contact: Sets output O2 to ON and sends command to devices in groups 4 and 5.
- Opening contact: Sets output O2 to OFF and sends command to devices in groups 4 and 5.
Push-button connected to input terminal SW2
When SW2 is configured as a push-button:
- Short press: Toggles output O2 state and sends command to devices in groups 4 and 5.
- Hold: Sends command to devices in group 4.
- Release: Sends command to devices in group 5.
Switching On/Off load connected to O (O1)
The load connected to O (O1) can be controlled via:
- Z-Wave commands
- Automatic switching enabled via Parameters No. 19 and 20
- Pressing the switch/push-button SW (SW1): toggles the load state
Switching On/Off load connected to O2
The load connected to O2 can be controlled via:
- Z-Wave commands
- Automatic switching enabled via Parameters No. 21 and 22
- Pressing the switch/push-button SW2: toggles the load state
Main Applications
