swithing off a mediabox with IR
« on: December 10, 2014, 03:33:28 pm »
After succesfully made a an actuator for my thermostate , it is time for the next project.

My audiosystem , Yamaha , I can controll via the plugin , also my Samsung , I can switch off with the plugin installed on vera 3 (with UI5) .
The mediabox, which is quite often forgotten to switch off ( and uses almost all my internet bandwith) has no plugin , just an old fashioned remote controll.

Hopefully I can change this with arduino.

The gateway is allready setup, and all the parts are allready in house to build this:
http://www.mysensors.org/build/ir

But I read somewhere on the mysensor forum , it doesn't work on Vera.  Anyone knows if it will work?

More to follow hopefully,
Cor

I can't help, but i'd be interested to hear if you have had any progress...?

I down have any experience with this setup but I'm quite sure the example from http://www.mysensors.org/build/ir will work with Vera.
The example simply creates a normal light switch in Vera and the "On" command sends one ir code and the "Off" command sens another.

The hard part might be to record the ir code using the receiver and then re-sending it using the transmitter, this is all done in the Arduino and has nothing to do with Vera.

I'm sure there is example code for the arduino out there that you can use to figure out how to record and re transmit the ir code of your choice.

There is a good library and example code for IR receive/transmit with Arduino by Ken Shirriff.

@ RexBeckett: thanks for the link , that should make life more easy :-)

@Korttoma: No progress so far,it is still very high on my todo list , but time is for the moment my bigest enemy .
I expect to start/continue this project within 2 weeks.

Offcourse I will post here all my findings.

Here wo go >>>>>>>

Today I have hooked up a IR reciever and transmitter on a arduino uno.
Uploaded the sketch and tried to controll the media box.

No , it isn't working , i think it is going wrong somewhere reading the IR-code.

Whatever button I press on a remote , it always shows the same code , for the transmitter of the mediabox it is "000000" , for the transmitter of a Yamaha amplifier , it is "ffffff" Every button on those remotes gives the same code, that can not be right.

Using the serial monitor this is confirmed. ( see the copy paste at the bottom of this post).

What is wrong? and what else can I try to read to correct code?

Thanks for the help ,

Cor

It looks as though it is reading something but not identifying the code. Have you tried any other remotes?

I don't recall having any issues getting Ken's library working. Do make sure that your IR receiver is the correct voltage for your Arduino. Some only work on a specific voltage (3.3V or 5V), some will work from 3V to 5V. I also find it helps to add a 100nF decoupling capacitor right on the power pin of the receiver.

@RexBeckett:   I tried 3 remotes , all 3 give a different code, but for every button it is the same code.

000000, ffffffff , and the last one is something different as well , but I don't remember.

Just checked the voltage:
http://www.ebay.de/itm/2x-Digital-38KHz-IR-Infrarot-Sensor-Transmitter-Kit-fur-Arduino-LS4G-/400602576265?hash=item5d45c63589   5v , that's correct.


100nF decoupling capacitor: I will get one of those today and try again.

Thanks for your help,
Cor

Digging back in my code archive, I found this sketch. I used it for early debug work on my IR receiver. It just prints the received codes including the raw data converted to Kira format.

Thanks RexBeckett,

It might be working ( with your sketch) , initially I recieved the same codes 000000 and fffffff, but suddenly I recieved something else.  and for every button a different code , so that's good news.

For the button I need , it spits out this code:  4CB0FADF

But no clue what I have to do with it, I inserted it in the mysensor sketch likt this:


Code: [Select]
void incomingMessage(const MyMessage &message) {
  // We only expect one type of message from controller. But we better check anyway.
  if (message.type==V_LIGHT) {
     int incomingRelayStatus = message.getInt();
     if (incomingRelayStatus == 1) {
      irsend.send(NEC, 4CB0FADF, 32); // on off mediabox
     } else {
      irsend.send(NEC, 0x1EE1F807, 32); // Vol down yamaha ysp-900
     }
     // Start receiving ir again...
    irrecv.enableIRIn();


But than I recieve an error message  from codebender when I verified and tried to upload.


I tried this:
Code: [Select]
void incomingMessage(const MyMessage &message) {
  // We only expect one type of message from controller. But we better check anyway.
  if (message.type==V_LIGHT) {
     int incomingRelayStatus = message.getInt();
     if (incomingRelayStatus == 1) {
      irsend.send(NEC, 0x4CB0FADF, 32); // on off mediabox
     } else {
      irsend.send(NEC, 0x1EE1F807, 32); // Vol down yamaha ysp-900
     }
     // Start receiving ir again...
    irrecv.enableIRIn();

No error message from codebender , but it also doesn't work.


Any idea what I am doing wrong this time?

*edit*

Oh .... this is wierd!!!!!

I wanted to try again and with the serial monitor I read the infrared code , it is different now.

Here the copy paste , I pressed THE SAME button several times:

With the decoupling capacitor , nothing is working , when I press a button on the remote , no response at all.
Thanks,

The decoupling capacitor should be connected between the 5V power pin of the IR receiver and ground. If it stopped working, you probably connected it to the data pin.

I notice that you removed the short delay I had in my code before re-enabling the IR receive function. It was there for a reason...

I don't know how I can help you with that. It depends on what you want the finished device to do. If you only need the ability to send on or off commands, you could just hard-code the values you find using the IR dump sketch. Presumably there is some appropriate binary switch sketch on MySensors that you could use as a base.

Oh h.... the decoupling capacitor between 5v and ground .... I had it only on between the 5V on arduino and the VCC on the IR .

Removed a delay? I just copy pasted it into codebender and uploaded it..... Where should this shirt delay be?

I did it twice; The first time when pressing the " on/off" button on the remote briefly:

I cloded the serial port , restarted and tried again, although very briefly pressed the same  button again , it gives me 2 different (!!) codes:
