以累积性连接Raspberry Pi [英] Connecting Raspberry Pi with cumulocity

问题描述

我已经用Cumulocity注册了Raspberry Pi设备. 现在我只想打开/关闭通过Cumulocity与Pi连接的LED.

I've registered my Raspberry Pi device with Cumulocity. Now I just wanted to switch on/off LED which is connected with Pi through Cumulocity.

是否可以，如果可以，如何进行?

Is it possible and if so how to proceed?

推荐答案

我建议使用c8y_Relay操作( http://cumulocity.com/guides/reference/sensor-library/)，因为基本上就是这种开(关逻辑，并且UI中已经有小部件可以触发操作(可以是添加到仪表板).

I would propose to use the operation c8y_Relay (http://cumulocity.com/guides/reference/sensor-library/) because it is basically this on(off logic and there are already widgets in the UI to trigger the operation (Can be added to dashboards).

在设备端，您首先需要将c8y_Relay添加到supportedOperations，然后实现一个OperationExecutor来处理该操作并切换LED(假设您正在使用示例存储库中的代理)

On the device side you would first need to add c8y_Relay to the supportedOperations and then implement an OperationExecutor that will handle the operation and switch the LED (assuming you are using the agent from the example repository)
