我们在IoT Agent Ultralight中发现了一个错误。
如果我们尝试将测量结果发送到非现有设备,我们会收到404 - DEVICE_NOT_FOUND
错误,但同时会在IoTA和Orion CB的数据库中创建没有任何属性的设备。
当我说一个没有任何属性的设备时,我会参考以下内容:
{
"device_id": "test",
"service": "MyService",
"service_path": "/MyServicePath",
"entity_name": "MyEntity:test",
"entity_type": "MyEntity",
"attributes": [],
"lazy": [],
"commands": [],
"static_attributes": []
}
这是一个非常重要的错误,因为创建尽可能多的设备非常简单,可能会占用我们的数据库空间。
有人知道如何解决它吗?
答案 0 :(得分:0)
从我的自我出发,我对其进行了测试,并且效果很好:
用于发送测量值的卷曲命令:
#!/usr/local/bin
mosquitto_pub -t /TEF/sensor03/attrs -m 't|45|c|extreme'
