Reverse engineering 433MHz signals of Velleman P8078 and Holtek HT46R01T3 or HT48R01T3, HT48RXX, HT48XXX (Arduino Library)
[HACKS] uC & Arduino Library: reverse engineering 433mhz signals of Velleman P8078 and Holtek HT46R01T3 or HT48R01T3 I reverse engineered a 433mhz signal of the 4xR01T3v130 / 46R01T3v130 / 48R01T3v130 chips which are commonly used by Tevion (Aldi product in Germany). As I normally use an Arduino uC I hacked a small library that is capable to sniff the air for interesting packets. The cause I needed to write it on my own and not using the various libs out there was: they just do not work (VirtualWire, RCSwitch, RemoteSwicth etc. etc.) as they are only for specific protocol types (called 1,2,3).
