Hi, From my old notes i did this: I added listen to: LIRCD_ARGS="--uinput --listen" in /etc/lirc/hardware.conf I don't know if this still holds true as it is more than a year since I tried it last time. Are you using the default port 8765 and have you checked that the port the port is open on your n...

Looking for some help I have lirc installed and running but having some problems with the irexec deamon. When I run irexec at the command line irexec runs the lircrc as written. When started at the command line as a deamon the lircrc commands don't execute. I have done the lircrc file both in the/e...

Hi very nice! How much range are You getting with those 433MHz TX&RX? Did You solder an antenna? Thank you! Best regards, Camillo I have succesfully tested it with a socket placed about 6-8m away through two closed doors. Its vital to have an antenna with the right length soldered to the transmitte...

The only thing you need to solder is the antenna cable to the small hole on the transmitter board. When connecting the board to your Raspberry Pi I would recommend using a set of female jumper cables. You can get them on ebay here . It would be a shame to solder something directly to the pins of the...

The tutorial has instructions on how to connect it to your gpio pins. The module itself has very limited range <1m, but if you solder an antenna of 17.3cm to the hole labeled antenna on the transmitter I have no problem controlling an outlet in our bedroom from our Livingroom >8m through two closed ...

Hi,

maybe you don't need a TellStick to achieve your goal? I Just succeeded in using a very cheap RF tranmistter <$2 from ebay to control some 433MHz RF outlets using rcswitch-pi. I wrote a small tutorial here.

Best regards
Martin

Hi, This tutorial will show you how to control your lighting and other devices with some cheap 433MHz RF based power outlets. The setup uses wiringPi for accessing the necessary GPIO pin, rcswitch-pi for sending the commands out of the 433MHz module and LIRC for controlling the whole thing when it r...

Hi Yonu, You need a driver to supply the IR leds with enough current and to prevent straining your GPIO pins ultimately frying your Pi. I have put a schematic for a very simple scalable driver on my website here http://www.datscharf.dk/amote/hardware/diy-transmitter/. Just increase the supply voltag...

@Douglas6: Thanks! It was really fun making stuff with beads again, it must have been like 30 years since I did that last time. @DougieLawson: Great that you have picked up the challenge :-), but I think you are going to have a hard time locking the parts together, unless you just glue it together o...

Hi all kids and crafsters :-), Spending the holidays with the kids playing with their new toys and otherwise enjoying spending time together I found myself creating fusible bead boards with my five year old son the other day. These versatile little plastic beads are great for improving motor skills ...

Hi Thomas, that is very much possible :-) Using a builtin function of lirc it is possible to execute commands of your choice. First you need a lircrc file either in your home folder called .lircrc or in /etc/lirc/ called lircrc without the '.' Try with putting this into the file: begin prog = irexec...

I don't think I can help you more than I already did. Either write your own raw command addition to lircd or look at the CCF patch from Bengt

mba

I am still not sure what you are after. Do you need to dynamically change the command you are sending based on the parameters and values listed in the excel sheet, making it impossible to create every command statically in lircd.conf? If so I guess theres no easy way other than implementing the raw ...

mba

You specify which pins you use when loading the driver. Look in /etc/modules. In my modules I have the following line: lirc_rpi gpio_out_pin=17 gpio_in_pin=18 These numbers correspond to the gpio numbers on the pin header . Make sure you know which revision of the Raspberry Pi you are using because ...

mba

Hi, I don't like looks of that circuit you linked to. First of all there is no resistor on he base of the transistor possibly straining the output from the RPi too much. Secondly there is no current limiting resistor in the path of the IR leds possible frying the transistor and/or the LEDs. Take a l...

mba

I am a bit unsure why you need to send the command in raw format every time and why its not possible to store the raw commands your AC knows in your lircd.conf? Or maybe I don't understand what you are actually trying to achieve altogether.

Could you try to explain your project in more general terms?

mba

Hi Mahendra, I just went through the installation myself. This is how you can compile and install lirc. 1. installed 2013-09-25-wheezy-raspbian.zip, expanded fs and enabled ssh 2. Edit modules and insert the following two lines at the end of the file. Replace gpio numbers with numbers that makes sen...

mba

What is the problem? Do you have any output from when lircd starts? Can you post your hardware.conf file. Have you setup lircd to start automatically? See my instructions around step 23. which describes how to make lircd start.

mba

Hi Mahendra, I have been thinking about your goal. You want to send raw codes from irsend right? As you know irsend doesn't support raw codes from the commandline, you can put raw code sections in your lircd.conf file and use irsend to send these commands using the remote and key name but I guess yo...

mba

Hi Mahendra, Try take a look at my original instructions here http://www.raspberrypi.org/phpBB3/viewtopic.php?p=146427#p146427 they might still work if you get the right kernel version. Ps. please don't contact me for help through personal messages, facebook, google+ and other places. Helping you he...

Hi, irexec is part of the LIRC package. Did you install it by calling: sudo apt-get install lirc Using irexec you need to create an .lircrc file and place it in your home folder like ~/.lircrc. Or you can create a lircrc and put it in /etc/lirc/ You should take a look at the fileformat of lircrc her...

mba

Great!

Just a quick question: is the SET_TRANSMITTER sticky meaning for how long is a transmitter (or transmitters) selected? Only for the next command you send or is it selected until you issue another SET_TRANSMITTERS?

mba

Hi elmicha, that sounds pretty cool, I am planning on using LIRC for both IR and RF controlling some 433MHz remote controlled power outlets. This way I can control which hardware gets which commands. Thanks for sharing this info. You don't happen to know if this will make it into the main repository...

Hi, If you specify the path to the .ko's then they should load. On my system: sudo insmod lirc_dev.ko Error: could not load module lirc_dev.ko: No such file or directory sudo insmod /lib/modules/3.6.11+/kernel/drivers/media/rc/lirc_dev.ko Error: could not insert module /lib/modules/3.6.11+/kernel/dr...
