That code doesn't seem right. Indeed too long.

After reading this whole thread, it looks like that the ID of the Group button is supposed to be '15'.

My unit is '8' since selected letter on the back of the remote is letter 'I'.
'15' seems to be the correct ID for the Group button, I also see in the pilight-receive result:

Code:

{
    "message": {
        "id": 15,
        "unit": 8,
        "state": "up"
    },
    "origin": "receiver",
    "protocol": "arctech_screen_old",
    "uuid": "0000-b8-27-eb-ebae7c",
    "repeats": 2
}

But when I send the following command, none of the 4 groups are switched ON...

Code:

pilight-send -p kaku_switch_old -i 15 -u 8 -t

Do I do something wrong?
