11 +
12 +
13 +BACnet, short for Building Automation and Control networks.
14 +
15 +The BACnet communication protocol defines a number of services for communication between devices, and services can be divided into five categories: services related to device object management including Who-Is, I-Am, Who-Has, and other services, services related to object access including reading attributes, writing attributes and other services, and services related to alarms and events include acknowledgment alarms, change of state reports, etc. In addition, there are services related to file reading and writing and virtual terminals.

26 +
27 +By following the steps below in the configuration example, Users can convert the uplink data of the lorawan sensor to BACnet data
28 +
29 +LPS8v2 includes a local ChirpStack Server. This example shows how to configure LHT65N to use with BACnet. This example assumes users already have:
30 +
31 +* LHT65N register on LPS8v2 Built-In ChirpStack server already
32 +* The user is able to see the data on the built-in ChirpStack server device page.
33 +
34 +Below are the steps to configure lps8v2 BACnet.
