You must configure allthingsusing this node. Use a differentsetupnode for eachtypein your flows. It is up to you how you organize yourtypes. We recommended you base them on the platforms you use -- in other words, based on how the devices connect into and out of Node-RED. There are ...

以下$project 阶段会省略 _id 字段,包含 name 字段,并创建一个名为 storeNumber 的新字段。storeNumber 是使用两个聚合运算符生成的: $split 会将_partition 值分成位于空格字符两端的两个字符串段。例如,以此方式分割值“Store 42”会返回一个包含两个元素的数组:“Store”和“42”。 $arrayElemAt 会根据第二...

The node outputs a payload onPIN 3, with the captured image (as byte array), that you can directly save to disk or attach on an email or so. This pin emits a message only if the camera sends the captured image. This usually happens with "smart" events (but many firmwares out there...
