A few years ago I bought (hornbach) very inexpensive remote power switches (intertechno par-1000) to switch on-off the lights in our living room. I found the protocol to switch them on/off. Then I tried to create a sketch. with the following protocol info.
Intertechno Protokoll
;
; 12 Datenbits + 1 Syncbit
;
; 0-Bit = 1T High + 3T Low + 1T High + 3T Low
; 1-Bit = 1T High + 3T Low + 3T High + 1T Low
; Sync-Bit = 1T High + 31T Low
;
; 1T etwa 360 Mikrosekunden
;
; 4-Bit Familiencode (LSB...MSB)
; 4-Bit Gerätenummer (LSB...MSB)
; 4-Bit Kommando (LSB...MSB)
;
; 0 = 1H
; 1 = 3L
; 2 = 1H/3H
; 3 = 3L/1L X 12
; ...
; 48 = 1H
; 49 = 31L
;
Familiencode:
a 0
b 1
c 2
d 3
e 4
f 5
g 6
h 7
i 8
j 9
k A
l B
m C
n D
o E
p F
Gerätenummer: (Gerät+Gruppe4)
Gerät: (x1)
1 0
2 1
3 2
4 3
Gruppe: (x4)
1 0
2 1
3 2
4 3
Command:
Ein 1110 -> 0E
Aus 0110 -> 06
I also tried the default kaku demo sketch, hmmm works like a charm and Solves my 220 volt problem.
