What is Blynk?
Blynk provides iOS and Android apps to control any hardware over the Internet or directly using Bluetooth. You can easily build graphic interfaces for all your projects by simply dragging and dropping widgets, right on your smartphone. Blynk is the most popular IoT platform used by design studios, makers, educators, and equipment vendors all over the world.

import BlynkLib
# Initialize Blynk
blynk = BlynkLib.Blynk('YourAuthToken')
# Register Virtual Pins
@blynk.VIRTUAL_WRITE(1)
def my_write_handler(value):
print('Current V1 value: {}'.format(value))

virtual_write
sync_virtual
set_property
log_event
- events:
Vn
,connected
,disconnected
,invalid_auth
TCP
and secureTLS/SSL
connection support- can run on embedded hardware, like
ESP8266
,ESP32
,W600
orOpenWrt
Ubuntu/Linux/Raspberry Pi installation
pip install blynk-library-python
For Blynk.Edgent Dynamic Provisioning, please see examples/Edgent_Linux_RPi
ESP32/ESP8266 installation
- Get the latest MicroPython firmware and flash it to your board
- Edit ESP8266_ESP32.py example (put your
auth token
and wifi credentials) - Use
ampy
or any other method to transfer files to the device
Note: LoBo firmware stores files uderexport AMPY_PORT=/dev/ttyUSB0 ampy mkdir /lib ampy put BlynkLib.py /lib/BlynkLib.py ampy put ./examples/hardware/ESP8266_ESP32.py main.py
/flash
directory, useampy mkdir /flash/lib
and so on - Open device terminal and reboot the board (or type
execfile('main.py')
) - For ESP8266, you may need to disable secure connection using:
blynk = BlynkLib.Blynk('YourAuthToken', insecure=True)
PyCom installation
- This should work with WiPy 1.0, 2.0, 3.0, LoPy, SiPy, GPy, FiPy
- Instructions are the same as for ESP32, just use PyCom_WiPy.py example
Implementations for other platforms
- Arduino
- Particle
- Lua, OpenWrt, NodeMCU
- Node.js, Espruino, Browsers
- OpenWrt packages
- MBED
- Node-RED for Blynk IoT
- LabVIEW
- C#
