161 +== 1.6 Example: How to transfer data to BACnet via LoRaWAN in LPS8v2 ==
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.
170 +
171 +
172 +=== 1.6.1 Link BACnet to Local TTN ===
173 +
174 +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"]]**
175 +
176 +For more information on importing Input Flow, check out this link:**[[Import Input Flow for Dragino Sensors>>url:http://wiki.dragino.com/xwiki/bin/view/Main/Node-RED/#H3.A0ImportInputFlowforDraginoSensors]]**
177 +
178 +
179 +After importing the Input Flow is complete, the user needs to edit the MQTT in the node
180 +
181 +Users can edit the MQTT node red color by referring to the following link:
