Hi Developers,

I have bought the following doorbell 433mhz sender, which does not need a power supply at the bell, because I do not want to work with Relais or with a sensor with battary.

> **[Graviers Funksignale Weiterleitung I Klingelanlagen Funkkonverter I Funk...](https://www.amazon.de/Graviers-Weiterleitung-Klingelanlagen-Funkkonverter-Steckdosenempf%C3%A4nger/dp/B09QL9BZYS)**
>
> Sie haben bereits eine Türklingel und möchten Ihre bestehende Klingelanlage kabellos erweitern? Nutzen Sie hierfür unser Erweiterungsset welches das Klingelsignal kabellos per Funk an bis zu 150m (Freifeld) entfernte Empfänger (Steckdosenempfänger...

Now I have recorded the signal with the following app

[http://htmlpreview.github.io/?https://github.com/harriedegroot/Athom-Homey-RF-Signal-Analyzer/blob/master/index.html](http://htmlpreview.github.io/?https://github.com/harriedegroot/Athom-Homey-RF-Signal-Analyzer/blob/master/index.html)

With the following result (did it two times)

```auto
Signal: {
  "sof": [
    268,
    786
  ],
  "eof": [
    267,
    65535
  ],
  "words": [
    [
      266,
      772
    ],
    [
      787,
      252
    ]
  ],
  "interval": 10000,
  "sensitivity": 0.5,
  "repetitions": 20,
  "minimalLength": 23,
  "maximalLength": 23
}

```

Payload: 00000000001101011111000  
Match: 100%

And the other one is that….

```auto
Signal: {
  "sof": [
    270,
    784
  ],
  "eof": [
    271,
    65535
  ],
  "words": [
    [
      266,
      773
    ],
    [
      788,
      251
    ]
  ],
  "interval": 10000,
  "sensitivity": 0.5,
  "repetitions": 20,
  "minimalLength": 23,
  "maximalLength": 23
}

```

Payload: 00000000001101011111000  
Match: 100%

Is there a devolper who can create an app based on this signals or information?

Thanks a lot for your support  
Berni

Thanks for the information, can you move this request to the other thread or do I need to copy and paste it?

BTW: I will donate the development for sure.

Sorry, no. You have to use a template to post your request.

Maybe you can write an app yourself, with this tutorial:

Then you can use [this tool](http://htmlpreview.github.io/?https://github.com/harriedegroot/Athom-Homey-RF-Signal-Analyzer/blob/master/index.html) 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…
