setProperty Blynklib.py

Smackflad · January 16, 2019, 10:48pm

Am I the only one that can not use the setProperty command in python?
I think that I have the latest blynk python library but I am not sure, i’d love to have a link to check it.
I did a pip install of the library, I downloaded from GitHub this library from the clone or download button
(when I use this library I cant even run the program, it says that the

BlynkLib.Blynk(Blynk_AUTH, ‘111’, 8080)

is wrong formatted,(error:)

TypeError: init() takes exactly 2 arguments (4 given)

), also I downloaded from the downloads button in the readme section of the GitHub page(this runs but it seams there isn’t a setProperty setting) but had no luck.
My code:

import BlynkLib

BLYNK_AUTH = ‘nn’

Blynk = BlynkLib.Blynk(BLYNK_AUTH, ‘111’, 8080)

@Blynk.VIRTUAL_WRITE(6)
def v6_write_handler(value):
Blynk.setProperty(V15, “color”, “#42D286”)
Blynk.run()

the V6 is a button that I press and the V15 is a button that gets its color changed.

Am I doing something wrong? Any ideas? thanks in advance!

This was already mentioned, and acknowledged by the developer, in another topic you were part of… and simply hasn’t been implemented yet… Patience.

This sounds like you are simply using the wrong format… what is the ‘111’ for?

Use just the needed arguments:

BLYNK_AUTH = 'YourAuthToken'

# Initialize Blynk
blynk = BlynkLib.Blynk(BLYNK_AUTH)

Update:

OK, I managed to manually install (aka copy over) the ver.0.2.0 Blynklib.py and it also gives me the same error, on a previously good script, when trying to account for my local server… which I now assume you were doing with the cryptic '111'

My recommendations for now is to stick with the ver.0.1.3 Blynklib.py until @vshymanskyy has time to look into it.

And to add to the fun… I did find this in the ver.0.2.0 Blynklib.py file…

But that file is actual dated prior to the previously referenced topic about it missing… and of course that version seems to have issues configuring with a local server… All so very confusing I am too exhausted to look into it anymore… right now…

Hey thanks for the research, yes I know that I already asked this in an other topic but some other blynkers commented on my topic and used the setProperty command and I think that they said it worked. That’s why I wanted to create a new clean topic with all the libraries I’ve installed just to make sure that it’s not already added.
Is there a way to automatically update the library when there is an update?
Also the ‘111’ is the ip of my local server(as correctly you assumed).

Also I’m so happy that you found it on the v2.0 that means it will work soon! That’s again…!!

@Smackflad setProperty does work with Python if you have the correct library.

Syntax is:

blynk.set_property(7, "color", "#ED9D00")  # set color for text on V7 to yellow

Smackflad · January 18, 2019, 4:01pm

Hey Costas glad you responded!
Well it worked with buttons does it work with the Image widget?
when I use that command:

blynk.set_property(5, “url”, 1, “http://0.0.0.0/Desktop/test3.png”)

it wont work, it returns a syntax error.

Again thanks for helping!

Smackflad · January 18, 2019, 4:13pm

For more info:
it says that the set_property takes exactly 4 arguments, 1 the self and 3 that the user gives(I suppose).
for the opacity, scale and rotation it works, for the url and urls it dosent.

Costas · January 18, 2019, 4:33pm

@Smackflad the following syntax is updating my images in Python:

blynk.set_property(5, “urls”, “http://0.0.0.0/Desktop/test3.png”)

Smackflad · January 18, 2019, 4:38pm

that’s odd, I just copy pasted this command and it crashed.
Also I can see in my http server logs that there is no request
code:

import BlynkLib

BLYNK_AUTH = ‘xxx’

Blynk = BlynkLib.Blynk(BLYNK_AUTH, ‘192.168.2.12’, 8080)

@Blynk.VIRTUAL_WRITE(6)
def v6_write_handler(value):
Blynk.set_property(5, “urls”, “http://xxx:xxxx/Desktop/test3.png”)
Blynk.virtual_write(5, 1)

Blynk.run()

maybe I have something wrong with my code?

Costas · January 18, 2019, 4:42pm

Look at my (excellent) code again!!!

Smackflad · January 18, 2019, 4:44pm

I’m sorry but I miss it… whats wrong with mine?

Costas · January 18, 2019, 4:45pm

lowercase blynk

Smackflad · January 18, 2019, 5:05pm

well I don’t think that that’s the case because I declare in the top Blynk = Blynklib.Blynk….
Also tried it like that:

import BlynkLib

BLYNK_AUTH = ‘xxx’

blynk = BlynkLib.Blynk(BLYNK_AUTH, ‘192.168.2.12’, 8080)

@blynk.VIRTUAL_WRITE(6)
def v6_write_handler(value):
blynk.set_property(5, “urls”, “http://xxx:xxx/Desktop/test3.png”)
print(“test”)
blynk.run()

and still wont work.

Smackflad · January 18, 2019, 5:06pm

if I declare it like Blynk and then use blynk it will crash when I execute the script

Costas · January 18, 2019, 5:11pm

All working fine for me but I am using external urls:

# initialize Blynk
blynk = BlynkLib.Blynk(BLYNK_AUTH, 'someserver.com', 80)

def blynk_connected():
    # You can also use blynk.sync_virtual(pin)
    # to sync a specific virtual pin
    print("Updating V2 from the server...")
    blynk.sync_virtual(2)	# just sync V2
    blynk.set_property(3, "urls", "https://peacefairapp.com/fota/pzem/images/PubBot.png") # OK update image on V3

Smackflad · January 18, 2019, 5:22pm

well I don’t know how is that possible…
can you please provide me a peace of code with virtual write?
press a button on v6 and update the url on the image widget v5.
I’m really excocted with this situation… 1 or 2 months I’m trying to figure this out

Smackflad · January 18, 2019, 5:29pm

changed the url and used your pub url and it still wont work…

Smackflad · January 18, 2019, 5:30pm

code:

import BlynkLib

BLYNK_AUTH = ‘xxx’

blynk = BlynkLib.Blynk(BLYNK_AUTH, ‘192.168.2.12’, 8080)

@blynk.VIRTUAL_WRITE(26)
def v6_write_handler(value):
blynk.set_property(25, “urls”, “https://peacefairapp.com/fota/pzem/images/PubBot.png”)
blynk.run()
