In contrast to the Bin-to-Light workflow, Put-to-Light is a method used in order sorting processes where items are brought to a designated location after being picked, and sorted into individual customer orders on a stationary Skublox wall.  There are two sides to the Skublox system – the sorting side and the shipping side.

Once goods are picked from the warehouse and brought to your sorting area, simply log into the Skublox Sorter app on your device and scan them. Skublox will automatically designate a slot for each scanned item, grouping products that belong to the same order together, and lighting up the assigned slot in your unique color. To confirm that the item has been placed in the slot, simply scan the slot barcode!

When all the items for an order are accurately assembled, the light on the shipper side of the wall turns green, indicating that this order is ready to be packed and leave the warehouse.

The Put-to-Light workflow is also available for Virtual Walls, which offer the same functionalities as a conventional light wall, without the need for hardware and cabling configuration.
For even greater details into the technology behind this, refer to our Sellercloud blog.

Manage Put-to-Light Walls

Following the initial wall creation, you can view and manage your Put-to-Light walls in the Put-to-Light section within the Skublox Hub:

  2. Enter your login credentials.
  3. Select Walls and choose the wall you want to view.
    • Active and ready-to-use walls have a distinct green dot indicator.
    • A flashing red dot next to the wall’s name indicates recent activity.
    • Virtual walls can be identified by a distinct robot icon next to their name.
    • Telemetry information is also available, showing information about either the current device running the Skublox Controller App or the last connected device in case the wall is currently disconnected.
