	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.

	81
	82	(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):

12.1	170
19.2	171
12.1	172	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:
	173
	174	* LHT65N register on LPS8v2 Built-In TTN server already
19.3	175
12.1	176	* The user is able to see the data on the built-in TTN server device page.
19.3	177
12.1	178	* The LPS8v2 already has BACnet installed
	179
	180	Below are the steps to plot the sensor data on LPS8v2 BACnet.

16.1	184
19.2	185
16.1	186	Users can download the Node-Red decoder from this link and import it into the Node-Red platform: [[attach:LHT65N_TTN_to_BACnet.json\|\|target="_blank"]]

16.1	189
	190
	191	After importing the Input Flow is complete, the user needs to edit the MQTT in the node
	192
18.1	193	Users can edit the MQTT node red color by referring to the following link:
