New! Alpha version of the blynk-library for Python!

For an alpha version, it is not strange :wink:

Hi vhymanskyy,

first of all thank you so much for providing the library!

I was just wondering if it is something related to my own Pi configuration.

Is it related to very fast refresh rates?

Generally I need to link my Pi to blink cloud in order to forward Virtual Pin data
to SC though OSC (Open Sound communication). This is going to be a non stop
running installation so do you think I should move for now to the node.js version?
Is that more efficient CPU-wise?


Node.js is better in 2 ways:

  1. the Blynk library is tested better
  2. JavaScript is event-driven by it’s nature

If you don’t have intensive computations in your code/libraries you use, I wouldn’t be concerned about Node.js or Python usage at all.

Hey, I’m kinda new to this…I need to sense a GPIO pin…but I can’t because it keeps executing
I need to continuously check the GPIO pins and excecute at the same time …
Can someone help me…thanks

@Aleric_Pinto I’m planning to change this in a week or so. I’ll update the library

Ohh okay thanks…will I able to execte what I require…?
And also digital pins are not supported yet I think…Any word on that.

Digital pins will not be supported. You’ll have to add virtual pins for your digital pins (~5 lines of code)

Yes I’ve been Doing that all along…thanks anyway

Good news here.
I found some time to do a major rewrite of the Python library!
It now contains only my code (previously some code was written by another guy), works better with MicroPython (LoBo/ESP32, etc.), and what’s most interesting - does not have the ugly concept of “tasks”.
It now works similar to Arduino - you have to run Blynk in a loop (but you can also use _thread).

I’m now polishing it, preparing some “getting started” docs, etc.


So, how are things going in the micropython world? Tried importing blynklib to my m5stack module, but isn’t working :\

Hi…Does the python library work with local server? i ran the example and look what i got… my pi is not connected to the internet.
Connecting to
Error: connection with the Blynk servers failed, connection closed

I know nothing about Python, but I’d assume that you need to edit your

def connect(self):
           self.conn = socket.socket()
           self.conn.connect(socket.getaddrinfo("", 80)[0][4])
           raise ValueError('connection with the Blynk servers failed')



Yes… and a little searching later… :wink:

Be aware that with the next update, it will be easier to change the server (still in the works)


Next update this week.

I have been slack in getting to this, but saw some recent changed on github, so after seeing that running the documented install file still gets 0.1.3. I just manually downloaded what looks like the latest Python 0.2.0 library and have it sitting in my RPi… There is a nice file called, but I can’t seem to get it to actually live up to its name :stuck_out_tongue:

The first lines in the file show this…

#!/usr/bin/env python

from setuptools import setup

Which doesn’t tell me much either… I looked for that folder, thinking I might find that setuptools program, but the folder doesn’t yet exist.

Googling a bit (yep I do that :wink: ) it seems I must setup setuptools in order to setup Blynk’s Python setup?? Wow… This linux/python stuff is hard :blush:

Any hints here? before I totally pooch my RPi setup :laughing:

In the same folder as, run:

pip3 install ./


pip2 install ./

Depending on the Python version you want to use the library with.
Anyway. The library 0.2.0 is almost ready for release (still working on some examples)

v0.2.0 is released and available via github and pip.

Please check out the new README and examples.

:star2: :star2::star2: And of course, do not forget to give it a github star! :slight_smile:
