A while back I bought a small USB rfid reader, after I got it, it turned out to be utter crap.

USB board

While in theory being very nice, it turned out to be a bit dissapointing. So I left it in lying in a box.
Yesterday I thought, lets use it for my domotica box. Now I can use the (few) RFID cards I have to enable/disable light/music/stereo.

To accomplish this I added a module to IfThenElse that can watch output and activate a specific branch depending on input, the script now looks as follow:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
25

[RFRead]
type=MultiOutputWatch
cmd=bash -c "while read input; do echo $input | tr -d \\r ; done < /dev/ttyUSB1"
fire_regex=.4E000477427F;.4500F6A0C6D5;.4E00044A6A6A;.4500F6A26978;.4E00047E3400
action=StereoOn;PlayMusic;LightOn;AllOff;Other
 
[StereoOn]
type=ExternalToolAction
cmd=stereo.sh on
 
[PlayMusic]
type=ExternalToolAction
cmd=mpc -h squeeze play
 
[LightOn]
type=ExternalToolAction
cmd=remote b 1 1
 
[AllOff]
type=ExternalToolAction
cmd=bash -c "switch_lights.sh all off; mpc -h squeeze stop; stereo.sh off"
 
[Other]
type=ExternalToolAction
cmd=mpc -h squeeze toggle

Now with a bit of creativety I could make ifthenelse branches being enabled/disabled based on the selected card . (I need to figure out how todo this propperly)
