[pimatic-homeduino] error: Couldn't connect to homeduino device: Cannot open /dev/ttyUSB0.

---

Hi,

I’m using a RPI2 and currently with pilight and pimatic and that is working fine. However I would like to get red of pilight but then I need to get my hardware running with pimatic.

I’ve installed homeduino but get the cannot open /dev/ttyUSB0 error.

Can someone please help me with this problem?

this is my config

{
“plugin”: “homeduino”,
“driver”: “serialport”,
“driverOptions”: {
“serialDevice”: “/dev/ttyUSB0”,
“baudrate”: 115200
},
“receiverPin”: 0,
“transmitterPin”: 4
}

@hamelsveld did you have installed an Arduino with the Homeduino Sketch?
Like here

@Icesory Hi, No I have it connected the same way as I did with pilight using the RPI only…

This is explained also in the howto.
http://forum.pimatic.org/topic/202/4-homeduino-433-mhz-sending-receiving-and-even-more/2

But it is highly recommend to use an Arduino.

@chris Hey Chris, had the same error message like the one in your first post.
Then i noticed, that all my actors are gone in the max software.
I Configurated them again and then deletet the max plugin and pimatic.js works now.
Maybe it helps.

@Icesory tnx for the tip I’ve changes my setup but what pin numbers do I need ?

I have now

{
      "plugin": "homeduino",
      "driver": "gpio",
      "driverOptions": {},
      "receiverPin": 17,
      "transmitterPin": 18
    }

this should be correct but now how can I find my ID’s because if I look in my debug logging I can’t see anything at all

logging >> debug >>homeduino

then I press my remote and nothing…

@hamelsveld I have edited your previous post to make it readable. If you wish to post code snippets and such, please have a look at the following post - http://forum.pimatic.org/topic/1179/how-to-post-code-on-the-forum

@mwittig tnx

please read you postet table exactly.
wiringPi has no pins with the number 17 and 18.
The simplest way for you is to use exact the wiring like explained in the howto.

have a look at the link from above
http://forum.pimatic.org/topic/202/4-homeduino-433-mhz-sending-receiving-and-even-more/2
there you can see how the hardware is connected to the pi and how everything needs to be configured. So pls - again - read the howto carefully.
usually you should see debug data when everything is wired correctly.

you’re having an error at your config.
you need to use the wirinPi GPIO numbers - the common GPIO 17/18 are wiringPi GPIO 0/1

so you’re config should look like :

{
  "plugin": "homeduino",
  "driver": "gpio",
  "driverOptions": {},
  "receiverPin": 0,
  "transmitterPin": 1
}

Hi,

Okay stupid me!!!
I had the id’s wrong mixed up the sender and receiver (sorry)

Now I’ve not the receiver working… in debug mode I see the following

and I’ve tested the following switches and ID’s but non of them are working…

 {
      "id": "switch",
      "name": "pimatic switch",
      "class": "HomeduinoRFSwitch",
      "protocols": [
        {
          "name": "switch5",
          "options": {
            "id": 262465,
            "unit": 3
          }
        }
      ]
    },
    {
      "id": "switch1",
      "name": "pimatic switch 2",
      "class": "HomeduinoRFSwitch",
      "protocols": [
        {
          "name": "switch5",
          "options": {
            "id": 6,
            "unit": 15
          }
        }
      ]
    },
    {
      "id": "switch2",
      "name": "pimatic switch 3",
      "class": "HomeduinoRFSwitch",
      "protocols": [
        {
          "name": "switch5",
          "options": {
            "id": 786110,
            "unit": 0
          }
        }
      ]
    },

So any ideas what i’ve got wrong this time? and I’ve the eurodomest switches i’m trying at the moment.

Some users had problems with the Eurodomest switches. It is said the quality of the RF-unit as part of the switches varies. See http://forum.pimatic.org/topic/788/eurodomest-not-always-switching-off

was a bit of a puzzle but have it all working now thnx for your support.

@hamelsveld You’re welcome! It’ll be great if you can summarize what did the trick?
