6. Setup & Installation
6.1 Mounting the Transformer
- Choose a suitable outdoor location near a 120V AC power outlet, ensuring it is protected from direct heavy rainfall.
- Use the provided mounting template to mark the drill holes on the wall or surface.
- Drill pilot holes and insert the wall anchors if necessary.
- Secure the transformer to the wall using the provided screws.
6.2 Wiring the Landscape Lights
The transformer features two output zones (Zone 1 and Zone 2) with common (COM), 12V, and 15V terminals for each. Ensure your landscape lights are compatible with 12V or 15V AC.
- Strip approximately 1/2 inch of insulation from the ends of your low-voltage landscape lighting cables.
- Connect one wire from your lighting circuit to the 'COM' terminal of the desired zone (e.g., Zone 1).
- Connect the other wire from your lighting circuit to either the '12V' or '15V' terminal of the same zone, depending on the voltage requirement of your lights.
- Repeat for Zone 2 if you have a second lighting circuit.
- Ensure all connections are tight and secure to prevent loose wiring and potential hazards.

6.3 Initial Power-Up and Wi-Fi Connection
- Plug the transformer's power cord into a 120V AC outdoor-rated GFCI outlet.
- Download the 'Smart Life' app from your smartphone's app store.
- Register or log in to your Smart Life account.
- In the app, tap '+' to add a device. The app should automatically discover the transformer. If not, select 'Electrical' -> 'Transformer' or 'Lighting' -> 'Low Voltage Transformer'.
- Follow the in-app instructions to connect the transformer to your 2.4GHz Wi-Fi network. The Wi-Fi indicator on the transformer will stop blinking once connected.

9. Troubleshooting
If you encounter issues with your DEWENWILS landscape transformer, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| Lights are not turning on. | No power to transformer, loose wiring, overloaded circuit, blown fuse, incorrect schedule. | Check power outlet, ensure transformer is plugged in. Verify all wiring connections are secure. Reduce the number of lights if exceeding 80% capacity. Check and replace fuse if blown. Review app schedules. |
| Wi-Fi connection fails or disconnects. | Incorrect Wi-Fi password, 5GHz network used, weak signal, router issues. | Ensure correct 2.4GHz Wi-Fi network and password. Move transformer closer to router. Restart router. Re-pair the device in the Smart Life app. |
| Lights flicker or are dim. | Voltage drop due to long cable runs, undersized wire, too many lights, faulty bulb. | Use heavier gauge wire for longer runs. Reduce the number of lights on the circuit. Check individual bulbs for faults. Ensure connections are tight. |
| Voice control (Alexa/Google) not working. | Incorrect linking of Smart Life account, device not discovered, voice command error. | Ensure Smart Life account is correctly linked in Alexa/Google Home app. Discover devices in the smart assistant app. Use precise voice commands. |
