Warehouse lights are controlled with Bluetooth mesh

The Bluetooth mesh control project – at McWong’s distribution centre in Sacramento – involves multiple luminaires from different manufacturers and demonstrates the interoperability of the technology.

A RETROFIT of a 25,000-square-foot facility in California is the biggest warehouse implementation of a Bluetooth mesh lighting network to date.

The project – at McWong’s distribution centre in Sacramento – involves multiple luminaires from different manufacturers and demonstrates the interoperability of the technology.

McWong has collaborated in offering qualified Bluetooth mesh solutions by putting firmware from Silvair into an array of products, including luminaire controllers, sensors and switches. The warehouse project in Sacramento is the first stage of the company’s plan to deploy Bluetooth mesh networks at its production and office facilities.

In the first phase of the retrofit, a wireless lighting control system powered by Bluetooth mesh was installed across the warehouse production space. Smart luminaries were installed above aisles and assembly areas. The retrofit itself didn’t cause major disruptions, allowing the facility to operate normally despite the ongoing implementation.

The project plan included integrating Bluetooth-enabled occupancy sensors for every new light throughout the warehouse, as well as wall switches at the exits.

A total of 12 lighting zones was created. As part of the project, a total of 22 luminaires from different manufacturers were installed across the warehouse.

Each fitting was then integrated with a smart occupancy and light sensor from McWong. A total of 22 such devices were used to enable deployment of autonomous occupancy sensing at the warehouse.

In addition, three wireless McWong switches were installed to allow the employees to control the installation manually whenever they needed.

McWong sensors are qualified Bluetooth mesh products with the Silvair Firmware inside.

In addition to occupancy and ambient light sensing capabilities, each such sensor includes a software controller that turns a standard luminaire into a smart node of a Bluetooth mesh lighting network.

This eliminates the need for a central control box, driving down the cost of the entire installation, reducing unnecessary complexity, and improving the reliability and scalability of wireless lighting control systems.

The system was configured using Silvair Commissioning, a dedicated set of tools for setting up and managing Bluetooth mesh lighting networks.

Silvair Commissioning includes a cloud-based web app, which allows for performing initial commissioning activities before visiting the site, and a mobile app that can be used to finalise the process on site.

McWong’s warehouse was primarily commissioned using the mobile app. As part of the process, luminaires were grouped into 12 zones, desired lighting control scenarios were specified, and occupancy sensing were adjusted to meet specific lighting needs of McWong’s employees.

With the first phase of the retrofit, McWong deployed a robust wireless control system that enables highly efficient control strategies. Future plans involve deployment of a gateway that gathers detailed occupancy and power consumption data from individual luminaires, enabling advanced monitoring and maintenance features developed by Silvair.
