IR Sender/Receiver built, now what?

[Justintime]

Hi all,

I have a MySensors IR receiver in combination with domoticz running for some months now and is working perfect for my needs.

I am using the X10 IR codes (because I found a library on the internet to decode the X10 IR codes with an arduino) which I can send via my Harmony remote control.
In domoticz I have defined 16 switches which are controlled by the MySensors sketch.....quite easy but it does the trick for me

I have included the sketch, the link to the library I could not find anymore but if you are interested in the X10 library please send me a PM.

Greetings Frank

What device did you use on the Harmony?

I used the "Marmitek IR-7242" device.

[flwvanes]

Thanks... I will try this out. Does every command make a new virtual device/switch in Domoticz?

No, this sketch is only working for 16 units, but you can expand it with more units by using the house code aswell (each house has 16 units).
(The X10 code is build of a "House", "Unit" and "Command" code if I remember well )

Within Domoticz I use the switches within a lua script to control some lights in the living room.

Code: Select all

commandArray = {}
if (devicechanged['IR 00'] == 'On') then
	if (otherdevices['Staande lamp'] == 'Off') then
		commandArray['Staande lamp']='On'
		print('IR Control - Staande lamp = ON')

	else
		commandArray['Staande lamp']='Off'
		print('IR Control - Staande lamp = OFF')
	end
	commandArray['IR 00']='Off'
end

if (devicechanged['IR 01'] == 'On') then
	if (otherdevices['Haard verlichting'] == 'Off') then
		commandArray['Haard verlichting']='On'
		print('IR Control - Haard verlichting = ON')
	else
		commandArray['Haard verlichting']='Off'
		print('IR Control - Haard verlichting = OFF')
	end
	commandArray['IR 01']='Off'
end

if (devicechanged['IR 02'] == 'On') then
	if (otherdevices['Tuin verlichting'] == 'Off') then
		commandArray['Tuin verlichting']='On'
		print('IR Control - Tuin verlichting = ON')
	else
		commandArray['Tuin verlichting']='Off'
		print('IR Control - Tuin verlichting = OFF')
	end
	commandArray['IR 02']='Off'
end

if (devicechanged['IR 03'] == 'On') then
	if (otherdevices['Rooster'] == 'Closed') then
		commandArray['Rooster']='On'
		print('IR Control - Rooster = OPEN')
	else
		commandArray['Rooster']='Off'
		print('IR Control - Rooster = OFF')
	end
	commandArray['IR 03']='Off'
end

if (devicechanged['IR 04'] == 'On') then
	if (otherdevices['Hang lamp'] == 'Off') then
		commandArray['Hang lamp']='On'
		print('IR Control - Hang lamp = ON')

	else
		commandArray['Hang lamp']='Off'
		print('IR Control - Hang lamp = OFF')
	end
	commandArray['IR 04']='Off'
end

if (devicechanged['IR 15'] == 'On') then
		commandArray['Staande lamp']='Off'
		commandArray['Hang lamp']='Off'
		commandArray['Tuin verlichting']='Off'
		commandArray['Haard verlichting']='Off'
		print('IR Control - Staande lamp, Haard verlichting en Tuin verlichting = OFF')

	commandArray['IR 15']='Off'
end


return commandArray

I have flashed the Arduino. And the marmitek device added in the Harmony. But there are no codes rolling by in Arduino Serial.

When i compile the arduino sketch there was a library missing the X10ex.h.

It was not in the link you have posted, so i grabbed it from somewhere....
Maybe thats why?? The Node is regonized in the serial and send is "ok"

You are correct.....I found the wrong library
I will send you a PM with the correct one.

[gizmocuz]

some heads up:

in the latest beta i implemented the mysensors S_IR_RECEIVE and S_IR_SEND

going to make two posts

Post 1:

When playing with the IR sample, i noticed that 99% of my remote buttons where not recognized, i only received pulsed, instead of a code

So.... i look at the IR library, and it has a nice example to make a 32bit hash of the received IR pulses.
This proves to be working very good !

I made a new sketch, that is using this hash code, and send it to domoticz (S_IR_RECEIVE)
A new switch (type mdremote) is created, and you can use this for example as the activation code of a scene

Next, when setting the type of the switch to 'push on' (as it is only received) you can also push the button in domoticz, and it will send the code to the sketch (S_IR_SEND)

you can do what you want with it

The sketch is:

But of course when your remote is recognized, you can make your own sketch, and use the S_IR_RECEIVED / S_IR_SEND types

Post 2:

What i am trying to do, is create a sketch to receive a raw IR code (normal remote, HAVC, ....) store it to disk,
and be able to load from disk, and send the raw pulses.

For me, i am trying to control an airco, this can only be done with capturing the 'raw' pulses, and send these 'raw' pulses.

So i am at the moment playing with an arduino uno with a ethernet sketch, and an sd card.

Via ethernet you can send simple commands like:

Learn <id> (for example Learn 1)
(This will learn a new raw pulse, and stores it on the sd card as file '1')

Send <id> (for example Send 1)
(This will load the sd card file '1', and send it out)

So this is for receiving/sending IR, not receiving IR and send it to domoticz

Because, every time the pulses are slightly different.

My current problems:
- making a sketch with ethernet/sd/ir with the default libraries results in a to large sketch to upload.
- at the moment i am using a custom ethernet library, this reduced a lot !, still to enough
- i replaced all strings in my sketch by encapsulating them in F("aaa"), this also reduced the sketch (user variables) a lot!, still not enough
- my test sketch now has 150 user variable space left, this produces a warning and can be dangerous

Of course a arduino mega would not have this problem, but... like to keep it small.

(for sure, a mysensor node would not work on the uno, thats why i am looking about a ethernet interface)

What i try to make, is good for universal IR transmit (capturing raw, sending out), it is not IR receive -> domoticz

Once i have it working, i will post all files needed to build my sketch.

We could use it with mysensors on a arduino mega, but then we need an addional V_IR_LEARN

Playing around with the Node. I see the ir signals gives a nice code.

In the Log i see the node being regonized. And as i understand for every command it will make a new switch/device? But i dont see new devices/switches.

[gizmocuz]

You have to edit the sketch and add your hashes

Best to debug with the arduino ide serial monitor

I control my rgb led cove by Domoticz and Milight. Made several scenes with different colors. Linked the scene to a Mysensors command. And done. Works great.

[gizmocuz]

it was a nice example how to use custom ir codes with the harmony

in reality you would just use the harmony actions as the scene code, and fire you lighting settings

Hi!
I have built a mysensors-IR node to control my ceiling fan. So far everything worked fine... I modified your sketch by adding my hashes, they were recognized and added in Domoticz as switches. Sending an IR command is also recognized by domoticz in the protocol.

Now I'd like to reverse that process and send IR commands via domoticz. I also converted the switches to "switch on" buttons. 2 Problems here, I hope someone can help me...

First thing: Hardware. Receiving works fine from the Button on the remote to domoticz. But when connecting the transmitter to Pin 3 like mentioned in the code (and disconnecting the receiver) I can't send anything as according to the serial monitor the node is constantly "receiving" some unknown IR hash, so sending is blocked. So... is it necessary to have the receiver and the transmitter connected?
When connecting transmitter and receiver, there is no wrong hash received, but sending still does not seem to work. Could be a problem with the software, which leads me to the...

Second thing: Software. In the hash, the transmit IR part is reduced to sending a message in the serial monitor. That works fine, when I press the button in domoticz, the assigned hash is sent to the node. But how do I have to configure the rest of the send function? I checked the IR header file and tried

Code: Select all

irsend.send(HASH_CODE, ir_code, 32);

but that does not seem to work, the IR transmitter remains silent. So... what am I doing wrong?
And, as the receiver pin is defined in the code, do I also have to define the transmitter pin?

Thanks for reading until here, I'd welcome any help I get!

[gizmocuz]

A Hash is just a Hash and not the actual code.

So lets say you can make a capture of the real IR code, save this to disk, and also include it in your sketch
for this IR code, a hash is received, lets say the hash is 123456
this hash is used as ID in domoticz, and when domoticz sends a switch command to the node, it sends 123456
your node has to look if it is 123456, and then send the real IR code from above

[blitzkneisser]

Of course, silly me, that's not what a hash is all about. I guess I just hoped for an easy solution without much thinking.
I'll try to embedd the codes in my sketch, it's not that much of them...
Thanks

Why not take a cheap (3euros) NodeMcu (ESP8266 ).
http://www.aliexpress.com/item/NodeMcu- ... 29505.html
- it is small as a nano, (including wifi). and can even be smaller (other ESP8266 versions)
- flash it with Arduino firmware
- connect a ethernet shied , or maybe just use the onboard wifi module
- optionally add a mysensor radio module
- ESP8266 has 4M of flash, YES 4 Mbytes !!!!!! .. a "little" bit more than the usual 32k

some helpfull building info at mysensors :

[blitzkneisser]

There's also the possibility to store user variables in program memory. I too had the user variable space warning - and the sketch did not work, but I had some program memory available. So I just stored the variables there, can be done with progmem.
I stored all my IR code sequences in program memory, see this thread for further details:
http://www.domoticz.com/forum/viewtopic ... 42&t=10678

[gizmocuz]

True, but with an ethernet sketch, sdcard sketch and ir sketch and some code it was to much
even used alternative ethernet/sdcard libraries that where smaller
