15.5. Sonoff
All Sonoff 433MHz RF receiver devices can be controlled by the RFXtrx433/E/XL using Lighting4
with a pulse timing of 370usec.
The 4 button Sonoff Lighting4 remote code:
The last digit indicates the button:
A 0001 hex 1
B 0010 hex 2
C 0100 hex 4
D 1000 hex 8
The first 5 digits are the ID. Here an example of ID=D216B button=A
Packettype = Lighting4
subtype = PT2262
Sequence nbr = 1
Code = D216B1 decimal:13768369
S1- S24 = 1101 0010 0001 0110 1011 0001
Pulse = 370 usec
Signal level = 8 -56dBm
The Lighting4 commands can be used for example to control the 4 relays in a Sonoff 4CH Pro
