Falmec Nuvola 90: reconstructing a 433 MHz remote protocol

Falmec Nuvola 90 remote research reconstructs the range hood's 433 MHz OOK control messages from captured signals. The documented 33-bit frame encodes fan speed and light state using 320 and 640 µs pulses; Python receiver tools decode captures, while Raspberry Pi and ATtiny85 transmitters send replacement commands.
