Can some one help me understand decoding.

Hi, every one.
My name is Ognjen and I am trying to write a small arduino code that would let me use my shutter remote for other things too.
Browsing the internet for solution I found this epic forum, I would like to apologize if I this is a wrong tread.

I have used pimatic library to read a few buttons signals from the remote… and they look like this:

Now i was thinking to save a code of a button up on channel 3 and make my device respond on that signal…
the problem is that I do not rly understand this codes and the codes are not same even if I press the same button several times…
So I have no idea how to write a “if” statement in my code to know if the up button is pressed when its code is never the same…

If some one could take some time to explain me whats going on here I would be grateful

Hi,

maybe its a rolling code system or somewhat encrypted. Maybe someone knows somewhat if you state the systems name? Which Shutters are this?

Thank you on your replay,

I have no idea what Shutters system name is…
All I could figure out is that it is manufactured in China and Turks and Greeks are selling it as their product.
The remote is having 5 channels and I am using only two of them, it somehow look to me that it is not rolling code and the remote is not having
receiver so encrypted handshake system is impassible.
I have divided the codes of different buttons press with ERR unknown_command and the codes for one button are very similar so it looks more like a bad coded remote than an encrypted.

I is normally the same code for one button usually?

you can compare the strings online fpr example and see tghe differences.

there’s the homeduino rawswitch device which you could try.
you just need your above raw codes for that. so its not neccessary to create a new plugin.
if its a “bad coded device” a plugin won’t help further… as said, try the raw switch.

Thank you on your replay.
I will tryout the raw switch.
