264 +== 2.4  Store Value ==
265 +
266 +
267 +Regarding storage, we recommend two ways.
268 +
269 +
270 +
271 +=== 2.4.1  1. Generate txt document directly ===
272 +
273 +Sample JSON file:链接转到示例JSON文件
274 +
275 +[[image:image-20220713102658-1.png||height="346" width="728"]]
276 +
277 +
278 +
279 +=== 2.4.2  2. Use sqlite database ===
280 +
281 +
282 +==== (% style="color:blue" %)**1.  Install SQLite**(%%) ====

293 +
294 +
295 +
296 +==== (% style="color:blue" %)**3.  Import sample flow**(%%) ====
297 +
298 +Refer to the import example below to import the sqlite example flow
299 +
300 +Download sample JSON file link: 链接
301 +
302 += 3.  Input Flow =
303 +
304 +
305 +Directly import JSON files to generate flow
306 +
307 +Download the required JSON file through this link: 提供一个链接
308 +
309 +Take LHT65 as an example  (this node is already registered with TTN,MQTT protocol to connect)
