Protocol

This protocol sends 50 pulses like this

270 810 810 270 810 270 270 810 810 270 810 270 810 270 270 810 810 270 270 810 810 270 270 810 810 270 270 810 270 810 810 270 270 810 270 810 270 810 270 810 810 270 810 270 810 270 270 810 270 9180

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:

270 810
810 270

The first group is defined by a low 1st and high 2nd pulse, hence we call it low.
The second group has a high 1st and low 2nd pulse, hence we call it high.

We then get the following output:

We then remove the first column of numbers and then put the remaining numbers in a row:

1001000101011011110001

Each (group) of numbers has a specific meaning and are defined in binary format:

ID: 0 till 19
State: 20
Unit: 21 and 22
All: 23

So this code represents:

Unit: 595311
ID: 0
State: On
All: Single
