[solved]homeduino only shows raw output for Brennenstuhl RCS 1000 N Comfort

---

Hello everyone,

I’ve got a problem with my setup.
I’m using a Raspberry 1 B, an Arduino nano, pimatic-homeduino plugin and Brennenstuhl RCS 1000 N Comfort remote controlled switches.

Everything is installed correctly and doesn’t show any errors on bootup etc.

In my config homeduino plugin is configured like this:

    {
      "plugin": "homeduino",
      "driver": "serialport",
      "driverOptions": {
        "serialDevice": "/dev/ttyUSB0",
        "baudrate": 115200
      },
      "receiverPin": 0,
      "transmitterPin": 4,
      "enableReceiving": true,
      "debug": true,
      "active": true,
    }

Now I tried to detect the right code for my Brennenstuhl RF switches (I think “switch 2” or “switch 3” should be the right protocol here).
After I press the button on my remote I get an debug output.
Unfortunately it only shows

17:22:01.649 [pimatic-homeduino] debug: received: [ 652, 1224, 1792, 9776 ] 1111201120202011202011203
17:22:01.787 [pimatic-homeduino] debug: data: "RF receive 1220 1856 592 9792 0 0 0 0 0000120012121200121200123"

and no other output like switch 1 or switch 2 or switch 3… etc.

I know my devices must work because I’ve have had them running without the way over the Arduino connected directly to my Raspberry Pi.

Can you please give me a hint what I have to do to get the correct switch code for my switches?

Regards
Tom

I use some Brennenstuhl RCS 1000 N switches (the “comfort” is missing). They work fine with switch2 protocol.
However, the houseCode is decimal and the unitCode binary or decimal. houseCode ‘11111’ has to be converted to 31. Below an example for button C:

    {
    "protocols": [
        {
          "name": "switch2",
          "options": {
            "houseCode": 31,
            "unitCode": 4
          }
        }
      ],
      "id": "some-id",
      "name": "some-name",
      "class": "HomeduinoRFSwitch"
    },

Button A will be 16 or 10000
Button B is 8 or 1000 and so forth

If you are unsure, how to convert, just ask Wolfram Alpha.

Edit: This page suggests, you may be better off with switch3.

Hi Marie,

thx … omg… that was a “no-brainer”.
I completely hadn’t in my mind that I just have to look on my switches what house / device code I have to enter.

It works. You saved my day

@Tom-Lan Glad, I could help Just curious: did you use switch2 or switch3-protocol?

I used “switch2” as protocol. Works fine…

"I can now confirm that Brennenstuhl RCS 1000 N Comfort and my old Dip-Switch-Operated Mumbi M FS300 work with the switch2 protocol

For further reference:

The House Code is read from left to right, unlike in pilight (right to left).

Pilight’s House Code 22 becomes 13 in pimatic. This reads as 01101 on the remote.
As described by @SLiX, 01010 on the remote becomes 10 in pimatic.
If unsure how to shift between the number systems, you can use any Binary-To-Decimal-Converter.
Unit Codes are mixed up as well, as @Overflow mentioned.

Pilight’s Unit Code 1, which triggers as A on the remote, becomes 16 in pimatic.
To my brief experiments, I could confirm that B => 8, C => 4, and thus presumably D => 2 (untested, though.)
Thanks a lot for all of your efforts. I hope we will have made it easier for everyone."
