问题​

1. mqtt设备/网关发送和订阅主题与平台不一致并无法修改，怎么接入ThingsPanel平台?

2. mqtt设备/网关json报文规范与平台规范不一致，怎么接入ThingsPanel平台?

使用规则引擎转发设备数据​

使用规则引擎转发设备数据的方式常用来解决第一种问题。

1. 在规则引擎中新建一条接入规则
2. 拖拽一个mqtt in节点，填写设备主题接入数据
3. 再拖拽一个mqtt out节点，与mqtt in节点连线
4. 在mqtt out配置中需要添加新的mqtt-broker节点，根据平台mqtt网关/设备接入规则填写主题和认证方式（AccessToken接入填写用户名,MQTTBasic认证填写用户名和密码）
5. 平台到设备的通信参考以上步骤
6. 除了以上节点，合理使用其他功能节点，也可以转换报文规范并对设备传输的值加工和处理
