Category - Devices group by their type that allows controlling all of them with voice assistants (Alexa, Google Assistant).

Claiming - a process of associating the device with the User (device owner). Usually used with devices that connect to the Internet using cellular or wired connection. WiFI Provisioning


Dashboard - a collection of Widgets

Device - physical or virtual appliance, Users can get telemetry from, configure, interact with, etc. Each device needs to be registered in the system.

Device Owner- a user considered to be a primary owner of the physical device.

Datastream - is a set of digital signals used for different kinds of content transmission.

Dynamic Auth Token - a unique identifier that is activated in the system and is assigned to each Device automatically during Wi-Fi Provisioning


Event - a recorded occurrence of an application-important event on the device


Firmware - a low-level software application that controls electronics and peripherials


HTTP API - a service that allows inter-operating with devices using a simple HTTP client. Devices can report their data using HTTP protocol.

Metadata - a {key: value} data associated with every device of a certain Template


Notification - a short message triggered by a certain Event and delivered to the specified recipient as an Email, SMS or Push Notification


Organization - a collection of users, devices, and locations

OTA (also FOTA) – Over-The-Air Firmware updates without accessing the Device physically.


Pin - GPIO (general-purpose input/output) pin on your Board used to interface with external hardware components (sensors, servo motors, LCDs, etc) of your Device.

Product - a Template published to Blynk.Marketplace and available for public use

Provisioning (also WiFI provisioning) - a process where the Blynk app sends parameters required to establish a WiFi connection to the device.

Profiling - a process of filling-out of Device Matadata after Claiming or Provisioning a device

Push Notification - a type of notification sent directly to the app on the smartphone


Shipment - OTA Firmwareloading to a single or multiple Devices

Static Auth Token - a unique identifier that is activated in the system and is assigned to each Device manually by editting the Sketch


Tag - a keyword or term that can be used to give a short description to a User or a Device

Template - a set of elements and configurations, used to display all Devices of a particular type. Templates are created by Developers, and can be published to be accessible globally.
