App Operating Instructions

Register an account
Scan the QR code below with your mobile phone and follow the prompts to complete the APP installation. 1.2 Open the App and log in or register an account.

Pairing instructions
After new users create a home in the APP, tap the “+” icon at the top-right corner on the Rooms page to add devices. In the device addition list, select either “Smart Gateway – Smart Gateway D3000”, “Smart Module – Smart Gateway D3000” or “Virtual Device -Smart Gateway D3000”, then follow the on-screen prompts to finish the device adding process.

Search DALI Addresses
Ensure no duplicate DALI power supply addresses and complete wiring in accordance with the wiring diagram on Page 4. After powering on, tap “Search Addresses” and wait for the address search to complete successfully.

DALI Luminaire Control: Addr & Grp
DALI Address Control: On the【Addr & Grp】page, tap the luminaire card of the corresponding address to individually adjust lighting effects for addresses 0–63. The control operation is identical to that of Bluetooth luminaires. DALI Group Control: On the【Addr & Grp】page, tap a group card to assign luminaires (addresses 0–63) to DALI Groups 0–15 for group control. The operation is consistent with Bluetooth light groups, and DALI groups support grouping multiple types of addressable luminaires.

DALI Luminaire Control: DALI Scenes & Broadcast
DALI Scene Control: On the【DALI Scenes】page, add up to 64 addressable luminaires and 16 DALI groups as actions for DALI Scenes 0–255 to realize scene control. After saving, tap “Edit Actions” on the settings page, then long-press the target luminaire or DALI group to quickly modify actions. Broadcast Control: On the【Broadcast】page, you can turn all luminaires fully on/off, adjust brightness, and tune color parameters including Tc, XY and RGBWAF.

Batch Settings for DALI Addressable Luminaires
Batch Parameter Configuration: Tap the ” ” icon at the top-right corner of 【Smart Gateway】homepage, then select “Batch Settings”. Select single or multiple luminaires and choose “Modify Parameters” or “Modify Room” to batch edit lighting parameters or the assigned room of selected DALI luminaires.
Batch Quick Access Management: Tap the ” ” icon at the top-right corner of 【Smart Gateway】homepage, enter the settings page and tap “Add Quick Access”. Select target DALI addresses, groups or scenes to batch add or remove corresponding quick access shortcuts.

Panel Device Binding
Switch to the Rooms page and tap the pre-added smart switch to enter【Control】page. Long-press the target button on the page, or switch to “Button Settings”. Select【Device】as the binding target, choose the corresponding action, and tap Save to complete binding.

Local scene 
Switch to the “Intelligence” interface, click【 + 】in the upper right corner to create a local scene. After setting the execution action, you can achieve local linkage with Bluetooth devices. When you edit the action for a local scene and a shortcut has been added to the DALI scene / group / addressable light , the editing steps will be shortened.

Cloud scene and automation
Make sure a smart gateway has been added to your home, such as Super Panel 12S. Cloud scene: Switch to the “Intelligence” interface and click【 + 】to create a cloud scene.After setting the execution action, remote linkage can be achieved.
Click【Automation】in the “Intelligence” interface and click【 + 】to create automation. You can choose the local or cloud execution mode, and set trigger conditions and execution actions. When the trigger conditions you set are met, a series of device actions will be automatically triggered to achieve remote linkage.
