Protocol

The techlico_switch protocol sends 50 pulses like this

208 624 208 832 208 624 624 208 208 624 208 624 624 208 624 208 208 832 624 208 208 832 208 624 208 832 624 208 624 208 624 208 208 832 208 624 208 832 208 832 208 624 208 624 624 208 624 208 208 7072

The last two 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 24 groups of 2 pulses (and thereby dropping the footer pulse).

If we now analyse these groups we can distinguish two types of groups:

  • 208 624
  • 624 208

The 1st group is defined by a short-long sequence (logical 0) The 2nd group is defined by a long-short sequence (logical 1):

Binary representation:

000100110100011100000011

We can group the sequence of bits into the following groups A and B:

AAAAAAAAAAAAAAAA BBBB BBBB
0001001101000111 0000 0011

Each of the groups of bits (A and B) has a specific meaning:

Group Bit # Config name Range Description
A 1 to 16 id: 1 to 65535 SystemCode id
B 17 to 24 unit: 1 to 4 ButtonCode unit

The protocol driver creates the binary presentation as required by the device

0000 0011 -u 1 Button A Toogle device status
1100 0000 -u 2 Button B Toogle device status
0000 1111 -u 3 Button C Toogle device status
0000 1100 -u 4 Button D Toogle device status

So this code represents:

{
   "code": {
      "id": 4935,
      "unit": 1
   },
   "origin": "receiver",
   "protocol": "techlico_switch",
   "uuid": "0000-00-00-00-000000",
   "repeats": 2
}

Examples

CLI command:

pilight-send -p techlico_switch -i 4935 -u 1

Known Limitations

As the device will not report its state, and the same Button on the original remote control toggles the state of the device, the GUI may show the wrong status of the device.
