Sniffing and replaying packets on 915Mhz

  Sending and receiving 433MHz signals with cheap GPIO RF modules on a Raspberry Pi

I'm not sure if this is the right sub to ask, but I have a remote controlled device that (supposedly) sends commands on 915Mhz. I want to sniff these commands and replay them, so I can control the device from my PC or some other device. I've already done this with some power outlets that are on 433Mhz with this: https://github.com/milaq/rpi-rf

• rpitx

  35 3,808 5.7 C

  RF transmitter for Raspberry Pi

https://github.com/F5OEO/rpitx With this program, a RTL-SDR and an antenna, I can control my lamp in my office who is plugged on a remote controlled wall plug.

• rtl_433

  172 5,719 9.3 C

  Program to decode radio transmissions from devices on the ISM bands (and other frequencies)

for sniffing out you can use RTL_433 (you can choose your own bandwidth) https://github.com/merbanan/rtl_433 you need a raspberry or linux computer with an RTL-SDR stick and antenna. I use it to sniff the 433 mhz range and get a lot of weather stations, tire pressures and alarm system. I feed them to a mqtt server and use some in my home assistant integrations (temperature of weather stations).
