How to create correct 433MHz signal.json file

[chuck_rui]

I have a 433MHz dimmer controller and i want add it to my homey app.
My homey app prj path “/.homeycompose/signals/433/dimmer_signal.json”

{
  "sof": [6000],  
  "sync": [
    400, 400, 
    400, 400,
    400, 400, 
    400, 400, 
    400, 400, 
    400, 400, 
    400, 400, 
    400, 400  
  ],
  "eof": [200,1000],  
  "words": [
    [0, 1],  
    [1, 0]  
  ],
  "bitlength": 8,  
  "baudrate": 1200,  
  "interval": 1000,  
  "sensitivity": 0.5,  
  "minimalLength": 10,  
  "maximalLength": 10,  
  "prefixData": [],
  "postfixData": [],
  "packing": false,  
  "txOnly": false,  
  "manchester": {
    "ManchesterUnit": 400  
  }
}

I use a logic analyzer to analyze the specific content of the 433MHz protocol emitted by my dimmer.

the 433MHz protocol(Manchester coding) data as below:
Preamble+Sync+Uid&Data+Stop

Preamble：

Sync：

Uid&&Data:

Stop:

400us L → 400us H =0(Low Level)
400us H → 400us L =1(High Level)

I also measured the 433MHz signal from my remote control through Homey Developer Tools, and the data is as follows (probably repeated several times).

420,838,836,826,833,834,833,836,416,416,833,834,834,835,834,833,822,427,416,417,428,398,438,815,853,397,428,835,832,416,415,417,416,836,416,426,824,826,843,417,418,406,426,837,824,842,832,833,414,417,833,416,427,792,436,404,425,412,423,404,841,415,417,417,416,835,834,417,418,834,415,416,843,823,844,823,833,835,418,416,426,407,427,408,833,426,408,834,416,416,844,824,417,416,418,416,427,407,844,405,417,417,417,416,417,418,418,418,418,417,427,406,416,417,417,416

But when I compile, I keep getting the “word_interval_out_of_bounds” error. I’ve been stuck in there for a long time. Could you help me change my signal definition file.

Maybe this helps a bit, Chuck:

RF Custom App: Signal (from signal analyzer) sent but not received

For anyone that would be interested in creating an Homey app for their RF device, here is how I processed: have a look at this: Tuto (Vidéo are helpful) Then use the Homey Developper Tool to register a button of your remote. Then you can use this tool made by someone here to make a first analysis of the signal. The goal is to identify the header, the trailer, and the data in the middle, and to compute an average signal (because of noise, each register session will result in a slightly dif…

Hi Peter，
I watched it. But my dimmer sends a Manchester coded 433MHz signal, and I saw that the description of parameters “agc”,“sof” and “eof” in the documentation mentioned that if you use Manchester coded “1” and “0” to fill in instead of filling in the time interval, But when I use “1” and “0” for padding, it says “sof” is out of bounds at compile time, I think this is because the Manchester encoding is not specified. Are there any parameters set to Manchester encoding?
