Notes

If you want your switch to learn new codes, you can use the following command:

pilight-send -p kaku_screen -i 1 -u 1 -t -l

If you want your switch to remove a learned code, you can use the following command:

pilight-send -p kaku_screen -i 1 -u 1 -f -l

Protocol

This protocol sends 132 pulses like this

The first 2 pulses are the header and the last 2 pulses are the footer. These are meant to identify the pulses as genuine. We don’t use them for further processing. The next step is to transform this output into 36 groups of 4 pulses (and thereby dropping the header and footer pulses).

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

  1. 272 1355 271 243
  2. 274 218 280 1358

So the first group is defined by a high 2nd and the second group has a high 4th pulse. So we take either of these two pulses to define a 0 or a 1. In this case we say a high 2nd pulse means a 1 and a low 2nd pulse means a 0. We then get the following output:

00000000000000000000000001010001

Each (group) of numbers has a specific meaning:

  • ID: 0 till 25
  • All: 26
  • State: 27
  • Unit: 28 till 31
00000000000000000000000001 0 1 0001
  • The ID is defined as a binary number
  • The All tells us if a code was meant for all devices with the same ID
  • The State defines whether a devices is opened or closed
  • The Unit is also defined as a binary number

So this code represents:

  • ID: 1
  • All: Single
  • State: Up
  • Unit: 1

Another example:

  • ID: 123456
  • All: All
  • State: Down
  • Unit: 15
