pimatic with homeduino using GPIO

---

Hi,

I would like to use the homeduino using the GPIO pins. It works in pilight (with the filter) but when I use it in pimatic I see nothing happening (even when using vhduino).

This is a part of the config:

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

The pins are the same as I’ve used in the pilight configuration.

The homeduino plugin is loaded without errors and the pimatic log shows “Connected to homeduino device.”

Any idea what is happening here? Should I use it without the filter?

thanks all

@rikki78
when pressing a switch on a rf remote or a wallswitch what happens at the debug output of homeduino?
are there any messages?

the Pin 0 and Pin 1 are the GPIO Pins from wiring Pi
On the Pi it would be Pin 11 for GPIO 0 (wiring Pi) / GPIO 17 (common) and pin 12 for GPIO 1 (wiring Pi) / GPIO 18 (common)
Guess you have connect the data wire from the receiver to pin 11 and the data wire from sender to pin 12 on the pi to get it to work?

here’s the howto wire things up with homeduino and gpio http://forum.pimatic.org/topic/202/4-homeduino-433-mhz-sending-receiving-and-even-more/2

Hi leader21.

thanks for the response. Yes, that is exactly how it is wired.

In pilight it works, so the wiring should be ok, right?
The homeduino ouput shows nothing when I press a button on a remote.

The picture you have linked has eventually a failure. The pins of the pi can handle only 3.3V but the receiver is connected to 5V so it gives a data output of 5V. It is possible that this killed your gpio pin.

Sorry, the picture is not completely how it is wired, there is an attiny in between with some resistors to compensate for the voltgae differences.
See this link

In pilight I do receive signals so the GPIO is ok.

the question is, if the attiny affects homeduino in receiving rf signals in either way.
did you try without the attiny (hopefully it’s not soldered)?
if so connect the receiver to 3.3V or with a voltage divider to 5V

i’m not sure, but i seem to recall that @sweebee formerly using an attiny as prefilter as well.

no I didn’t try I without the attiny, I will try it shortly.
I would expect though there should be at least some output on the homeduino…
I have the feeling I misconfigured something very small…

The attiny dons´t affect homeduino. With gpio it should reduce the cpu usage. So this is ok. I think you have a configuration or installation failure.
But sweetpi has change the Gpio driver in the last week. So eventually there is a bug in now.

all right, can I try an earlier version perhaps?

regarding the configuration / installation that could off course be… I’ve also tested with vhduino and I don’t get anything either

I have now updated pimatic and homeduino to the latest versions.
I was testing with pilight and had the daemon running in a different terminal.

When I now start vhduino and type

RF receive 1

I see:

However, after closing the pilight daemon, I see nothing in vhduino anymore!
When first starting vhduino and than pilight, nothing is happening either. So I have to exit both, start pilight and than vhduino.

In the pimatic messages window I still see nothing…

When starting pimatic I do see this message:

unknown message received: running on a raspberrypi
14:12:36.437 [pimatic-homeduino] Connected to homeduino device.

Debugging is enabled:

  },

Please tell me what I can do to further investigate this…

I found the problem! After adding the gpio plugin to the config I am able to receive signals! Transmitting is not yet working though.
