01-Add Device

To add a device; When broadcasting to MQTT, the devicename in the message created as devicename/topic is used.

You can see this format in the examples we made with Arduino ide.

We need to comply with this message structure in different devices and programs.

Click the Devices button from the menu.

In the window that opens, click the add device button.

Device name and device code are required in the pop up window.

The device name can be a name that will make it easier for us to remember.

The device code should be the name we use in our program.

Device name: Nodemcu1

Device code: device1

Let's make our settings.

Click the create button in the window.

Our device has been added to the system. We can see it in the list.

Let's click on the variables button to add the variables that will come from the device to the system.

In the new window that opens, we can add a variable with the add button.

Again, the variable name can be a name that we can easily remember. The variable topic name must be the same as the topic in our message content.

Variable name : Temperature

Variable topic name: temp

Let's make our settings

Click the create button in the window.

Our variable has been added to the system. We can see it in the list.

In the whole system, we can access the data in this variable by first selecting the device and then selecting the variable.
