trying to get an unsupported remote decoded

[finity69x2]

I'm trying to get this remote decoded to add support for it.

I haven't been able to get the protocolless analyzer to work yet and hopefully soon that will be addressed in another issue thread. Until then maybe someone can help by going this route.

I've managed to get some additional information.

I captured a button on the remote using a rtl-sdr dongle with SDSharp and brought it into audacity.

Here is the pulse stream:

the stream above repeats 3 more times on every button press. From looking at the codes they aren't all exactly the same. It looks like the first two bursts are the same & the second two bursts are the same.

And I analyzed the raw signal using rtl_433. Here are the results:

Hopefully this will give some more information to help me make some progress on this.

I have bad news.
That protocol (from the view in audacity) is not compatible with rcswitch.
The most you can aspire to is to write code to "play" the signal when you need. Receive it to trigger actions would be much more complex.
If you want to do the first task, you need to use SimpleRcScanner. Keep the button pressed during several seconds while recording.
With the timings, you can follow:
#163 (comment)

Get your hardware working first! You can assign the correct value to receiverPin, using the macro definitions "D1" - "D16", if you use Arduino IDE. For example:
static int receiverPin = D4;

Ah, that signal looks very similar to my remote (Hunter Douglas ceiling fan). RC Switch doesn't print anything in serial monitor when I press a button on the remote. Why can RC Switch not handle this? Is it because of the preamble and that 'silence' between the preamble and the actual code? Also is there somewhere a description of the different protocols RC-Switch supports? That would also help me understand what the limitations are.

Exactly

Also is there somewhere a description of the different protocols RC-Switch supports?

Single gap (sync bit) between repetitions of a set of bits, each bit encoded as two levels, with different duration of the levels for 1s and 0s.

[robbymeier]

Thanks for the response. Actually, I wonder why the preamble and pause is an issue. This is really just to tell the receiver to be ready for a signal. Then the signal comes. Everything else before can be ignored. Can this be done with RC-Switch. If so, is there any issue with the type of signal my remote sends out? Basically it just sends I think 66 bits where 0=100 and 1=110 with each of the 3 digits in 100 and 110 having the same length.
Here is an image of one such sequence. All to the left is the preamble (AAAAAA), followed by a pause and then the actual signal that I need to detect.

If RC-Switch cannot handle this, then do you know of another Arduino library that can?

This is like my segnal !
I solved without library in raspberryV2: https://github.com/mttstt/remote-control-shutters.
Works like a charm.
Now, I am porting on esp8266

Your code is just for transmitting!
