This is an upgrade project, through the addition of loRa gateway and node equipment, wireless connection, unified management.

The project uses 2 LG-01 gateways and 100 N04 loRa nodes to upgrade the original library building. The VAV controller can be added, but the site does not have the conditions for wiring network communication, so N04 is used to connect BACnet MSTP VAV controller, so that it can realize the wireless connection of loRa, and then access the BMS integration platform through the gateway for unified management.
