Note

The lastest version, Silvercrest (60494) RCS AAA3680-A isn't supported (yet).

-t --on             send an on signal
-f --off            send an off signal
-u --unit=unit      control a device with this unit code
-i --id=id          control a device with this id

        "living": {
                "name": "Living",
                "switch": {
                        "name": "switch",
                        "protocol": [ "silvercrest" ],
 			"id": [{
				"systemcode": 22,
				"unitcode": 0
			}],
                        "state": "off"
                }
        }

This protocol sends 50 pulses like this

312 936 936 312
312 936 312 936
312 936 312 936
312 936 936 312
312 936 312 936
312 936 936 312

312 10608

It has no header and the last 2 pulses are the footer. These are meant to identify the pulses as genuine. The next step is to transform this output into 12 groups of 4 pulses (and thereby dropping the footer pulses).

312 936 936 312
312 936 312 936
312 936 312 936
312 936 936 312
312 936 312 936

312 936 936 312

312 936 936 312
312 936 936 312

312 936 936 312
312 936 312 936

312 10608

If we now look at carefully at these groups you can distinguish two types of groups:

1. 312 936 936 312
2. 312 936 312 936

So the first group is defined by a high 3th pulse and the second group has a low 3rd pulse. In this case we say a high 3rd pulse means a 0 and a high 3rd pulse means a 1. We then get the following output:

01101 01000 01

Each (group) of numbers has a specific meaning:

• Unit: 0 till 5 (inversed)
• ID: 6 till 10 (inversed)
• Check: 11 (inverse of state)
• State: 12 (inversed)

10110 00010 0 0

• The Unit is defined as a binary number
• The ID is defined as a binary number
• The Check is always the inverse of the state
• The State defines whether a devices needs to be turned On or Off

So this code represents:

• Unit: 22
• ID: 2
• Fixed: Off
• State: On
