Nice work! I'm impressed.

[mortommy]

Thank you!

i take it i could use an Arduino nano and not have to worry about the voltage Regulator? it can take 5v or 3.3v meaning i already have all the parts to replicate this with my existing Dioder setup..:)

Thank you for the awesome work you have done! Would you be willing to share your OpenHAB items and sitemap setup to get this to work?

[mortommy]

I'll post items, rules and sitemap as soon as I'll have the stable version.

This is great.

I just got myself one of these Dioders

Could you detail the connections between arduino and the ikea board?

For example when you label AIN6 on the ikea board picture it connects to D6 in arduino?

• 3 for RGB (AIN6, AIN5, AIN4) - (D6, D5, D3)
• 3 for Buttons (OEN, AIN2, AIN3) - (D7, D4, D2)
• 1 ground
• 1 5v to arduino vin?
• 1 Color Wheel (AIN7 to Arduino A0)?

Is this correct?

[mortommy]

Hi,
3 pins for RGB: R (AIN4) -> D3; G (AIN5) -> D6; B (AIN6) -> D5
3 pins for buttons: S1(AIN3) -> D7; S2(CEN) -> D2; S3(AIN2) -> D4
1 ground
1 5V to Arduino's Vcc if it is 5V version or to RAW if it is 3,3V version
1 color wheel (AIN7) -> A0

Thanks @mortommy

@mortommy Thank you!

[mortommy]

I just updated the rules.

[loralg]

@mortommy Awesome thanks for the update!

[kevvette]

Just for clarification, you posted in a comment that S3(AIN2) -> D11 but shouldn't it be D4 per schematic and source code? Also, it looks like R20 has been removed. Why was that done and is it critical to make this work? Thanks, nice work.

[mortommy]

Hi @kevvette ,
yes, my mistake, S3 goes to D4, I'll correct the post, thank you.
Regarding the R20, it is just a jumper and first I thought I could use that point for some connection but at the end I didn't use it, so I reestablished the connection. It is not needed to remove the R20.

Hello,

Very nice project!
Is it possible to use in DOMOTICZ?

Hi,

if you are already using a gateway in Domoticz I guess so. From the mysensor point of view is a RGB sensor (or light switch or dimmer light) the source of the command sento to the serial gateway and then to the ikea mysensorized sensor it doesn't matter.

Hello,
I was using your code from MySensorDioder_133.ino
I downloaded the library from https://github.com/mysensors/MySensors
I tried to run the code but I got a error message saying no such file located.
These were the two files that couldn't be found
MyTransportNRF24.h
MySensor.h
I was wondering if you had the same issues when you were working on the code?

[mortommy]

Hi,
yes it happens sometimes. Try to import the library by Arduino IDE (Sketch -> Include Library -> MySensors). You'll have in the sketch two new lines:

#include <MyConfig.h>
#include <MySensors.h>

and you can delete the same lines already included in the code.

Remember that the sketch is based on mysensor library 1.5.4 it is not converted to 2.0 yet.

Hope it helps.

[Juan8taco]

Thank you,

I found those missing files and uses the mysensor library 1.5.4 but after I put all the files it asked for I got this odd message. I was looking for the error but had no luck. It says that "was not declared in this scope". Did you happened to run into this issue?
