HowTo receive & transmit infrared

---

thank you for your quick reply. yes, i used the sketch from https://www.mysensors.org/build/ir and today i had time to try your code, but i am getting the same output. the node is not presenting and in the pimatic-mysensors log it only shows a lot of the messages i already quoted.
btw that is not the first node i am building and i tried the same promini-8m and nrf with a light-sensor what worked fine. could that issue be a result of the mysensors-library version? i am using 1.5

edit: i tried the sketch without the irsend-part and the node sends its sensor-info and received ircodes too. but i still do not know, what is the problem with the irsend-part.

I solved the described issue with a little modification of the sketch, I added the following:

#include <MySigningNone.h>
#include <MyTransportNRF24.h>
#include <MyTransportRFM69.h>
#include <MyHwATMega328.h>
MyTransportNRF24 radio(RF24_CE_PIN, RF24_CS_PIN, RF24_PA_LEVEL_GW);
MyHwATMega328 hw;

and changed

MySensor gw();

to

MySensor gw(radio, hw);

Now i works but i don’t know why Can anyone explain that to a newbe?

I have a very basic question: I followed the steps in the linked tutorial but during the test run it looked like I didn’t receive any signals. I assume this is because I’m using an arduino and connected the receiver to P5 - in the config files I set the GPIO to “5” but I’m not sure if that’s correct?

Any chance somebody can help me out here?

@GuybrushMR80
you referr to the mysensors solution that sweebee postet above?

sorry, only just now realized that someone replied

I’m referring to initial tutorial from @thymian - I assume it has something to do with the GPIOs, not sure how they “convert” into those on the Arduino.

sorry, i still don’t get it.
you are using an arduino for receiving IR signals?
or are you using an arduino on GPIO5 ?!?
i am confused …

the tutorial from @thymian is for the raspberry pi and not for any arduino

for checking the gpio on the pi see here

so pin 5 is GPIO3
and pin 29 is GPIO5

maybe this helps?!

Thanks for your reply - I’m such a n00b, I must admit.
So I have an Arduino connect to my Raspberry Pi and basically all my setup is on the Arduino (which basically is the 433Mhz transmitter and receiver). Are you saying I can’t connect the IR hardware with the Arduino? If that’s the case, can I just use a second breadboard for my Raspberry Pi directly and connect the hardware there!?

@GuybrushMR80 said in HowTo receive & transmit infrared:

can I just use a second breadboard for my Raspberry Pi directly and connect the hardware there?

of course you can, or better - you must
connecting the ir tansmitter or receiver to the arduino without the correct sketch (firmware) for the arduino doesn’t lead to any result. so you are having an homeduino device (arduino with homeuino sketch and 433MHz hardware attached). as said, it’s not possible to use IR hardware without changing the arduino firmware.

from the actual point of view you should get a breadboard and build the ir circuit as shown in the tutorial and process the tutorial step by step.

what exactly do you want to receive / transmit?
if it’s a tv remote or similar, you could have a look at the pimatic-harmony-hub in combinattion with the logitech harmony hub. i am using it for some day now and it works perfectly for me!

Thanks for your answer - very helpful and much appreciated! I’ll order a second breadboard right away!

My plan ist user my Harmony Hub together with the Harmony remote to trigger events in pimatic, like turning the lights on via 433Mhz wall plugs. The Harmony / Hub doesn’t support this but if I just use a random IR device to trigger the events that should be possible I think… fingers crossed.

@GuybrushMR80 this will work. Did it already. I’m currently Not able to install lirc correctly. Hadnt the time to Flash a new raspbian Image by now Have fun! You Can ask if you have any Trouble with pimatic-lirc.

btw - if your breadboard for the arduino has some space you certainly can use it with the ir receiver and sender too!! they don’t need much space (three pins afaik), so it should be possible .

thank you so much for your support! I’ll give it a try and report back!

OK now finally I found some time to work on this!
I connected my Raspberry Pi to the breadboard and setup the wiring according to the sketch above.
Unfortunately I still have the same problem: If I execute

mode2 -d /dev/lirc0

and point my remote at the receiver and press some buttons, nothing happens.
I only have a receiver because I won’t need a sender but that should not be an issue, I guess…
Any idea how I could test this further?

anyone able to help with the above?

@GuybrushMR80 did you add dtoverlay=lirc-rpi,gpio_in_pin=pinnumber,gpio_out_pin=pinoutnumber to your config.txt and rebooted?

That made it work for me… I didnt follow this outdated tutorial though… Cant find the one i used.

thanks for your reply - yes, I added that line as well. Could it be an issue that I don’t have a sender but only a receiver? And that I’m using an Arduino which is connected to the Raspberry Pi as well? I wonder if there’s a way to see if the hardware is working and connected correctly - maybe some way to “ping” the GPIO pin I’m using…?

I found a possible issue in my setup: following the instruction in the original post, I connected the TSOP38238 accordingly. Now I looked up the actual datasheet and it looks like OUT and VCC are switched! At least I interpreted the circle in the drawing above as the little “knob”, pointing to the right.

Here’s the datasheet:
http://www.vishay.com/docs/82491/tsop382.pdf

Now after switching OUT and VCC it’s still the same result but of course now I have no idea if I just broke the IR receiver…

@GuybrushMR80 try this without the leds.

Hello,

I am using some sensors with mysensors in pimatic and it works fine but i also want to use mysensors for turning my tv on and off. I used a mysensors switch to send a IR code with a rule but i stil get an error of pimatic:

error [pimatic]: Could not find an provider that provides the next action of "send Ir nodeid: “5” sensorid: “0” cmdcode: “0x342333"”.

What iam doing wrong. In my debug i see the ir sender.

Thanks gerrit
