💬 Infrared Sender and Receiver

[Reza]

domoticz doesn't support this ?! i test this and i see domoticz wont detect this node

[zhangzc]

Hi @Reza ,
Did you solve this problem?

[Reza]

@zhangzc

hi , no . i can not use this device with domoticz

[chuckconnors]

@Reza said:

this module ( ir transmitter ) is weak in transmit . for more than 2 or 3 meter distance dont work . also for less than 1 meter we must direct connection exactly.
i think this is related to power or noise or problem of module ?!
can you guidance me ?

I'm thinking of building this but am concerned about limited range. I'd like it to work 10ft/3m. Can someone confirm that this does not work at these distances? If so, is there a way to increase the range?

[Wackid]

So how can is set this node in learnmode?? V_IR_RECORD in the Serial of Arduino?
How do i store codes in the Eprom. SO i can use them in Domoticz

[Wackid]

@Wackid

I know how to read out the IR signals. And to put it in the sketch manually. But I really like to make use of the record function.
Where and how do I make the node to set it in learn function.

[tiana]

I send command from remote control arduino read this command (i can see this in serial monitor) but this commands are not sending to gateway, my radio is working the sensor connect to gateway and controller. I use example Sketch given up in this page without changing anything.
Any idea whats wrong in my setup?

I use this IR transmitter toward my LG Tv and it works at a distance of ~3.5 m, but IR LED must be well pointed to the Tv, otherwise it doesn't work.

@Talat-Keleş
Hi, I am having an issue compiling the sketch and was wondering if you had any input or could help me out, This is what I get back when I try to compile;

[Talat Keleş]

@ramoncarranza
Compiler complains about not understanding decode_type_t. It should be defined in .h file or maybe you defined it in sketch but there is a problem definetly.
Can you post whole sketch and IR library and error message if any other so we can check and test.

By the way, I installed IRremote.h (v2.1.0) via library manager, and default sketch compiled without error on IDE 1.6.5 win7 and IDE 1.6.10 linux mint 17.

Re: 💬 Infrared Sender and Receiver

How do you enter the raw IR codes, i.e. those that aren't covered in the sketch? I have one through the receiver in the format - 23784 1800 -800 950 -1700 1800 -850 900 -850 950 -1700 1800 -850 900 -850 900 -850 950 -800 950 -850 900

[pete1450]

@ramoncarranza When I went and looked where the library manager installed the IRremote lib(for me C:\Users\User\Documents\Arduino\libraries), it had given it an odd name like arduino_294267. I renamed it to IRremote and the issue went away.

[hashem25]

I am confused i see the decode in my com monitor and i see the ir node in my domoticz but there is no data???

[wilson64]

Can I use MQTT & Node Red to make this work, if yes can somebody show me how

[Mitja Blazinsek]

ok i record ir code 240E4F17 from my AC remote hov can i sent this code from my controler to IR node and request from node to sent that code (on/off) AC i was trying with raw mesage but i dot know what to send (Type/ Sub type , Acknowledge/ Payload)

[dbemowsk]

So, I am thinking of building this and I noticed that the documentation says that you may need a mega to do this. Is a mega required, or will the code work with a nano or an uno?

@Newzwaver see @pete1450's post above (5 posts above yours).

Trying to compile the Infrared Sender and Receiver sketch to be used on a WeMos D1 Mini Pro (ESP8266) but I get the following error:

Seems like the saving/reading to/from Eeprom is handled differently when it comes to ESP8266.
So what do I need to change in order to get the sketch to compile?

Sketch:

/**
 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.

 *******************************
 *
 * REVISION HISTORY
 * Version 1.0 - Changed for MySensors usage by Bart Eversdijk
 * Version 1.1 - Added option to record manual presets up to 240
 * Version 2.0 - Migrated to MySensrors version 2.0
 * 
 * DESCRIPTION
 *
 * IRrecord: record and play back IR signals as a minimal 
 * An IR detector/demodulator must be connected to the input RECV_PIN.
 * An IR LED must be connected to the output PWM pin 3.
 *
 *
 * The logic is:
 * If a V_IR_RECORD is received the node enters in record mode and once a valid IR message has been received 
 * it is stored in EEPROM. The first byte of the V_IR_RECORD message will be used as preset ID 
 * 
 * If a V_IR_SEND the IR message beloning to the preset number of the first message byte is broadcasted
