Devices are the basis of IoT applications; you can think of them as field workers. They can measure and collect data -
sensors - and/or execute commands to control some mechanism -
There are 3 types of
Peripheral- devices that can NOT be connected to the internet.
Gateway- devices that handle the communication between
Standalone- devices that can collect data AND connect to the internet, so they can communicate with
Cervellodirectly without the need for
There’s a lot of data associated with each device, but
Cervello categorizes them by their purpose:
Telemetriesare the data that is being measured and collected by the device, i.e. temperature, humidity, etc….. and they change frequesntly.
Attributesare any metadata the user wants to add to the
device, i.e. firmware version, location. Normally, they don’t change frequesntly.
Alarmsare the alarms raised by the device
Eventsare the monitored actions of a device.
Devices are not only important because they allow us to monitor and control equipments in the field, but also because they collect data; the most precious resource for any successfull business.
Cervello makes the process of creating and managing
devices easier by supporting autoprovisioning, where the user can add all his devices by uploading a file, instead of creating them one by one.
device is connected, we want to make sure that this is the real device, not an impersonator. This can be acheived by generating credentials for the
device then must use the generated
token to authenticate itself.
You also can create multiple devices up to 1000 using device template.
Devices can be grouped using tags.
You can also create command or create commands from command template also you can execute commands on a device directly.
