Description

Describe the bug.

unfortunately I don't have the means to test this myself, but I was told from a discord member that KL: Sommer remotes created from the add manually function apparently don't work and send unvalid signals. this is an image he sent

I'll attach a signal I recorded from my remote to compare

G_raw.sub.txt

Reproduction

  1. add manually a KL: Sommer remote
  2. try to pair it to a Sommer receiver
  3. doesn't work
  4. try comparing to a recorded signal from a physical remote and the signal looks like it's scrambled up

Target

Sommer S 9060 pro (receiver)

Logs

Anything else?

I'll provide with whatever else I'm told is needed to debug and solve this issue, sorry for not being able to provide more info since I'm very much unexperienced in this and I lack another device to read signals from the flipper

Research direction
Examine the provided raw signal file (G raw.sub.txt) and compare it with the encoding algorithm in the Sommer protocol implementation (likely in lib/subghz/protocols/sommer.c). Identify discrepancies in pulse timings or bit encoding. The issue may be related to the 'add manually' function which generates signals differently than recorded ones. No linked PRs found.
