	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.

	77	After the configuration is complete, run the following command to start BACnet, The following are two ways to run BACnet:
	78
	79	(1) With /etc/config/bacnet configuration, and to run the registration server on the current machine, start it with the following command (configure the /etc/config/bacnet file correctly):
	80

	82	(((
2.1	83	bacserver -c -s
10.1	84	)))
2.1	85
	86	(2) Without /etc/config/bacnet, and to run the registration server on the current machine, start it with the following command:

10.1	88	(% class="box infomessage" %)
	89	(((
2.1	90	bacserver -s -a 10.130.2.80 -p 47808

	162
	163	LPS8v2 includes a local TTN Server and Node-Red. This example shows how to configure LHT65N to use with the BACnet. This example assumes users already have:
	164
	165	* LHT65N register on LPS8v2 Built-In TTN server already
	166	* The user is able to see the data on the built-in TTN server device page.
	167	* The LPS8v2 already has BACnet installed
	168
	169	Below are the steps to plot the sensor data on LPS8v2 BACnet.
