Actions or commands can be received from Bytebeam by subscribing to the actions MQTT topic:

/tenants/{tenant_id}/devices/{device_id}/actions

Replace {tenant_id} with your project name and {device_id} with the device id. You can find these in the JSON file downloaded in the section on Connect to Bytebeam cloud

To trigger an action from the cloud follow the guides on Creating new Action Types and Triggering an Action. Let us assume an action called print has been created that prints the payload:

Once the action is triggered you will receive a message on MQTT:

In the above JSON id is a unique identifier generated each time an action is triggered from the cloud. payload is the text payload that was entered on the cloud.

We need to send a response back to the cloud to indicate progress of executing the command. The response needs to be published on the below topic: /tenants/{tenant_id}/devices/{device_id}/action/status

And the payload will look like this:

In the above action response

Open MQTTX and click on the + New Subscription button:



Enter the topic (Replace tenant and device_id) and set QoS to 1:

Hit confirm. You should see the subscription now:

From the device management screen on your project trigger the print command:

This will open up a dialog as shown below. Enter payload and click on "Yes":



You will see the action get created with status as "Initiated"

On MQTTX you should now receive a message like below:



Notice the id in the payload matches the id on the you see on the UI. Ignore the additional field kind. That field has been deprecated.



You can send progress back as shown below:

Do not forget to set the id to what was received in the message by you and also change demo and device id 2 to your tenant and device id

You should now be able to see the action as completed on the UI



You can implement the below logic for implementing actions
