217 +
218 +LPS8v2 includes a local ChirpStack Server and Node-Red. This example shows how to configure LHT65N to use with the local Node-Red server. This example assumes users already have:
219 +
220 +* LHT65N register on LPS8v2 Built-In ChirpStack server already
221 +* The user is able to see the data on the built-in ChirpStack server device page.
222 +
223 +Below are steps for LPS8v2 to transfer data from a node to the TCP server.
224 +
225 +=== 3.6.1 Link Node-Red to Local ChirpStack ===
226 +
227 +Users can download the Node-Red decoder from this link and import it into the Node-Red platform:
