Device
A Device represents the connection between your physical hardware and TagoCore. Think of it as a digital identity for your sensors, controllers, or any IoT equipment. You need to create a device in TagoCore before any hardware can send or receive data.
TagoCore communicates with your devices using standard HTTP requests with JSON data format - the same technology that powers websites, making it easy to integrate with any hardware platform.
Adding a Device
To add a new device, click the 
button on the Devices page. This will open the device creation form:
Fill in the basic information like device name and description, then click create. TagoCore will automatically generate the security credentials your device needs to communicate.
Token & Serial Number
Every device gets a unique Device Token - this works like a secure password that allows your hardware to send data to TagoCore or receive commands from it. Only devices with a valid token can communicate with your platform.
:::danger Be careful Device tokens should be kept secret and only shared with trusted team members. Treat them like passwords - if compromised, you can regenerate them in the device settings. :::
Payload Parser
Payload Parsers help you transform raw data from your devices into useful information. For example, if your device sends hex data like 41BC7E, a payload parser can convert it into readable values like {"temperature": 23.5, "humidity": 67}.
