💬 Infrared Sender and Receiver

[Mash]

I am having trouble doing IRSensor with domoticz.
After pouring the scketch into the arduino, saved my codes and
to check that it worked well with MYSController, here's what
I obey when I activate the device under Domoticz:

"error sending command to the switch, please verify device/hardware"

My material in place:
Domoticz V. 3.8153 sur Raspberry PI 3
Gateway USB MySensor V. 2.1.1 on Arduino Nano
IRSensor V. 2.0.0 on Arduino Nano

For information in the domoticz log:

-The node is well detected

2017-12-28 09:07:12.553 MySensors: Node: 7, Sketch Name: IR Rec/Playback
2017-12-28 09:07:12.554 MySensors: Node: 7, Sketch Version: 2.0

-When I send a pre-recorded order with the remote control

2017-12-28 09:07:59.346 (MySensor) Light/Switch (IR Command)

-When I activate the device in Domoticz

2017-12-28 09:08:29.835 User: Admin initiated a switch command (149/IR Command/Off)
2017-12-28 09:08:29.836 Error: MySensors: Light command received for unknown node_id: 6

Someone would have any idea?

Thanks for your help.

sorry for my English

@mash please don't post the same question in multiple places. Posting in multiple places will divide the discussion, causing people to waste their time.

If anyone has any ideas on how to help @mash, do not reply here. Reply in https://forum.mysensors.org/topic/8793/problem-with-irsensor-and-domoticz instead.

sorry, forgave me I would not do it again

Hello
Using the example sketch from the main thread, I managed to program a few pilot buttons in the domotic. (IR codes are of course entered in the section: IRCode PresetIRCodes [] = (...).
I would, however, "upload" a few IR codes to Domoticz, which would control my TV and AV via the IR diode from the Domoticz level.

In this example, there is the sendRCCode () function, which, in theory, sends an IR code (previously uploaded to Domoticz) via IR diode, if of course it will get
message.type == V_IR_SEND.

I added an additional declaration:
MyMessage msgIrSend (CHILD_ID, V_IR_SEND);
but in Domoticz there was no additional Device that would be responsible for sending IR codes.
I think I probably need to do an additional Dummy Switch, which will send an IR signal transmission command to the gateway / node using JSON.
I'm thinking about it for a long time and I have no idea how to do it in DOMOTICZ.
Please help me how to do it.

Hi All, has anyone had any success porting this IR sketch example to work with the IRremoteESP8266 library? I am not getting much further than @korttoma.

Thanks CV8R.

Hi everyone I am trying to setup a node to control my A/C unit and am having some trouble.

I am using these libraries
MySensors at version 2.3.2
IRremote at version 2.2.3

My hardware is
Arduino mega 2560
Nrf24

The problem is if i press a button on the remote i get this on the console

Received : -1 UNKONWN B5E9B811 (32 bits)
Raw (38): -17746 8350 -4250 500 -1600 550 -1550 550 -1550 550 -500 450 -1650 550 -600 500 -1550 500 -1550 600 -4100 550 -1550 600 -1500 500 -550 600 -1500 550 -550 550 -500 550 -500 550 -500 650

So i uncommitted this

// Raw or unknown codes requires an Arduino with a larger memory like a MEGA and some changes to store in EEPROM (now max 255 bytes)
// #define IR_SUPPORT_UNKNOWN_CODES

to this

// Raw or unknown codes requires an Arduino with a larger memory like a MEGA and some changes to store in EEPROM (now max 255 bytes)
 #define IR_SUPPORT_UNKNOWN_CODES

but now if i compile the code i get this error

exit status 1

@catchra in bool storeRCCode(byte index) you need to change

#else
    return false;
  }
#endif

to

#else
    return false;
#endif
  }

The clue was in the verification output:

C:\Users\Micke\AppData\Local\Temp\arduino_modified_sketch_286541\sketch_may25a.ino: In function 'bool storeRCCode(byte)':

Also, pressing ctrl+t to auto-format the sketch can help a lot.

[bollarcreets]

Following (I think) the instructions to the letter:

• Using a Pro Mini
• Installed the IRremote library (current version through Arduino Libraries Manager: 2.8.0)
• Copied exactly the sample code

When I come to compile, I get the following error:

Am I missing something?

@bollarcreets, I am afraid that the script has never been adapted to the evolution of the IRRemote library.
If you take library version 2.2.3, the script will compile.

If you take the source code from the latest version 2.8.1 you will also see that the typedef enums AIWA_RC_T501 and MITSUBISHI are commented out.

If you want to run this example script with the latest version of the library, you will need to analyse and understand the script in order to modify it...

@evb said in 💬 Infrared Sender and Receiver:

If you take library version 2.2.3, the script will compile.

That does indeed work - thanks!

What's the best way to get the tutorial edited to include this information?

@bollarcreets I've added a note in the instructions. Please let me know if you think it could be reworded or put someplace else to make it clearer.

@mfalkvidd thanks, that change is all that's needed I think. Thanks to you and @evb for the prompt help!
