Protocol

This protocol sends 50 pulses like this

189 567 567 189 189 567 567 189 189 567 189 567 189 567 567 189 189 567 189 567 189 567 567 189 189 567 567 189 189 567 567 189 189 567 189 567 567 189 567 189 189 567 189 567 567 189 567 189 189 6426

It has no header and the last 2 pulses are the footer. These are meant to identify the pulses as genuine, and the protocol also has some bit checks to filter false positives. We don’t use them for further processing. The next step is to transform this output into 12 groups of 4 pulses (and thereby dropping the footer pulses).

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

1. 189 567 567 189
2. 567 189 567 189
3. 189 567 189 567

• The first group is defined by a low 1st and low 4rd pulse pulse, hence we call it low.
• The second group has a high 1st and 3rd pulse, hence we call it med.
• The final group has a low 1st and low 3rd pulse, hence we call it high.

We then get the following output:

LLHLH LLLHM HM

All L’s can be translated to 0, the H’s to 1’s, and M’s to 2.

Each (group) of numbers has a specific meaning:

• Unit: 0 till 5
• ID: 6 till 10
• State: 12 (state)

00101 00012 12

• The Unit is defined as a binary number
• The ID is defined as a binary number combined with a letter
• The State defines whether a devices needs to be turned On or Off

So this code represents:

• Unit: 10
• ID: A2
• State: On

Another example:

• Unit: 0
• ID: B1
• State: Off
