Can´t pair my Shutters

Hello,

i try to pair my shutters with the Somfy-Pi but they are not responding to it.
I have two Somfy Telis 4 RTS Pure Remotes with Number 74300 printed on them.

I made an Somfy-Pi first with FS1000 Emitter and now with CC1101 Emitter.
With the FS1000 i can´t get the frequency to match, with the CC1101 i am now between my two telis remotes.

When i start the programming of my blind i press on one of the remotes the programming button and afterwards the shutter jogs up/down. Pressing the programming button in Somfy-Pi does not do anything.

I looked now with my SDR what the remotes are sending if i press the middle button and when i press the middle button in somfy-pi and the results are not really the same?! Do i have the wrong remotes because it says RTS Pure on the back?

What does that mean? They're both sending something at the right frequency, right?

But that something changes every time, the protocol uses a rolling code.

Yes, they both send something at the right frequenzy.

But on my Telis it seems to be a single burst all the time and the pi sends multiple bursts as you see in my screenshot.
I think that could maybe be the problem why i can´t sync the shutter with my pi?

commented

The script simulates a slightly longer press, I don't see how that would be an issue.

Check your PiGPIO timing: #136 (comment)

Thanks fot the tipp with the timing.
My PCM-Clock is off by factor 2, so i switched to the PWM-Clock which is at factor 1.007 and now all five shutters work.

Great to know!

Hi,

I'm a beginner in the raspberry pi world, this project looks great but I'm stuck at this stage... I tried hayguen's clock test and it looks like I have a factor 2 in PCM too.
Everyone is talking about switching to PWM, but I have absolutely no idea how to do it, or what it means ^^
Can someone explain me how to switch from PCM to PWM?
Thanks

commented

Hi Rodd8,

just try this code ;-) -t0 sets the PWM-Timer

sudo systemctl stop shutters.service
sudo killall pigpiod
sudo pigpiod -t0
sudo systemctl start shutters.service

Greetings

Thanks for this it was exactly what I needed to get mine working :) however it seemed to be needed after every reboot. I asked ChatGPT how to fix and it told me the below which helped me, just incase anyone else runs into this issue

To make the change stick after rebooting your system, you can add the command to your system startup scripts. Here's how:

  1. Open the terminal and type sudo nano /etc/rc.local. This will open the rc.local file in the nano editor.
  2. Add the following line before the exit 0 line: /usr/bin/pigpiod -t 0
  3. Save and close the file using Ctrl + X, then Y, then Enter.
  4. Make the file executable with the following command: sudo chmod +x /etc/rc.local
    Now, after every reboot, pigpiod will be automatically started with the -t 0 flag.

That's a great use of ChatGPT
