i made a few mistakes in my first protocol analysis... I wanted to go too fast :slight_smile:
The _ is valid. It represent something as any other bytes.

I never tried to decode something... But i'm trying.
The first and the second set of 7 bytes aren't in the same order...
first set:
byte 6 could be hour.
byte 7 could be minute.

Second set:
byte 1 could be SensorID(door 1, door 2)
byte 2 could be hour
byte 3 could be minute

It's a good challenge isn't ? :slight_smile:
