How to sniff Kinetic Switck - 433 mhz

Other Hardware Home Automation
1

Hi guys, my intention is to receive the RF signal of the Kinetic switches like the following Wireless Switch, and eventually decode the data.
I've searched the internet for several days but there isn't much about this switches, also have tried all sort of things without success.
This are not conventional RF switches, they don't have battery, and send a very short message.

The frecuency is 433 mhz and the modulation is FSK.
I'm using an ESP32 and a RFM69HW receptor. I've tried with lot of libraries but they are not compatible with the A7329 chip http://www.amiccom.com.tw/asp/product_detail.asp?CATG_ID=1&PRODUCT_ID=87 that is the one this switch got inside.

I used audacity to record the waveform and actually got the following result in multiple ocations:

I've managed to send with the rfm69hw a very similar message to the switch receptor but didn't succeed.

I'm wondering if any of you have tried with this switches or if someone could help me with this matter.

Thank you very much,

Joaquin.

HI Joaquin,
working with the 433 mHz receiver and transmitter on an arduino board is very difficult.
I also have trouble working with it.
If you are able to use a Raspberry Pi and the 433library (GitHub - ninjablocks/433Utils: 433Kit is a collection of code and documentation designed to assist you in the connection and usage of RF 433MHz transmit and receive modules to/with your Arduino and Rapberry Pi.) it is way easier reading the data sent by the switches. You can find all infos how to use it on the github page above!
Kind regards
