214 +
215 +
216 +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:
217 +
218 +* LHT65N register on LPS8v2 Built-In ChirpStack server already
219 +* The user is able to see the data on the built-in ChirpStack server device page.
220 +

222 +
223 +
224 +=== 3.6.1 Link Node-Red to Local ChirpStack ===
225 +
226 +
