259 +== 2.4 Store Value ==
260 +
261 +
262 +Regarding storage, we recommend two ways.
263 +
264 +
265 +=== 2.4.1 (% style="display:none" %) (%%)Method 1: Generate txt document directly ===
266 +
267 +
268 +Sample JSON file: [[https:~~/~~/www.dropbox.com/sh/mduw85jcuwsua22/AAAvwPhg9z6dLjJhmZjqBf_ma?dl=0>>https://www.dropbox.com/sh/mduw85jcuwsua22/AAAvwPhg9z6dLjJhmZjqBf_ma?dl=0]]

271 +
272 +
273 +=== 2.4.2 Method 2: Use sqlite database ===
274 +
275 +
276 +==== (% style="color:blue" %)**1.  Install SQLite**(%%) ====

287 +
288 +
289 +
290 +==== (% style="color:blue" %)**3.  Import sample flow**(%%) ====
291 +
292 +
293 +Refer to the import example below to import the sqlite example flow

298 += 3. Import Input Flow for Dragino Sensors =
299 +
300 +
301 +Dragino provides input flow examples for the sensors.
302 +
303 +User can download the required JSON file through [[Dragino Node-RED input flow template>>https://github.com/dragino/dragino-end-node-decoder]].
304 +
305 +Take LHT65 as an example  (Assume this node is already registered with TTN, MQTT protocol to connect)
