The Bluetooth mesh community has made more progress indoors than I foresaw as possible. We recently covered an indoor Bluetooth mesh project covering a 22-story office building with one network — no gateways or servers required. EMC, Silvair, and McWong combined on the project. And additional energy savings beyond LED installation covered the ROI. That’s progress. But the project was based on the use of McWong sensors/controllers throughout and uniformity came based on the fact that the mainly commercial-use office space was served by identical troffers throughout.
The Minnesota project certainly proves out many of the claims made by Bluetooth mesh proponents. EMC installed 3685 luminaires in a one-for-one retrofit of existing lighting. And later EMC upgraded an additional 225 luminaires in common areas such as elevator lobbies with Bluetooth nodes. And all of those luminaires are connected in a single Bluetooth mesh network with no gateways required. The building does serve many tenants. So the new lighting has been commissioned and organized into 43 separate control areas with a total of 708 control zones. So each tenant has control of their own space.
