The spoof_temp from rgerganov

spoof_temp's Introduction

Command line program for spoofing the outdoor sensor for this temperature station (sold by LIDL):

The original sensor transmits on 433MHz and uses OOK to encode data. This program can encode data in the same format and transmit it with HackRF. You can see it in action here:

Convert cu8 to Flipper Zero sub format

Hello. Sorry for the offtopic question, but do you know by any chance if it's possible to somehow convert the cu8 files produced by rtl_433 to the Flipper Zero .sub format? Thank you.
