💬 OH MySensors RGBW Controller

[AWI]

@Jan-Gatzke for Domoticz you can use V_TEXT. You can request a value and manipulate it in Lua. Also Domoticz is terrible with rgb as it only allows saturated colors.

[AWI]

@Jan-Gatzke the FastLED library allows for very fast math with color values. Also some very educational stuff for color manipulation in the code and documentation.

[Jan Gatzke]

@AWI

Thx for the info. This comes 24 hours to late.

[pepson]

Is any chance to also project PCB for radio RFM69HW ?

[LastSamurai]

@pepson I wont do it because my networks is using NRFs but the kicad files are online, you could just get those and only change the radio part.

[pepson]

I dont know software kicad... and can i please you to help me for changing it to radio RFM69HW please ?

[hek]

@pepson, please respect @LastSamurai (who has gracefully shared his hardware design files) when he says he won't change it.

There are resources online on how to learn Kicad,

[tbowmo]

@pepson

There are also converter boards available, that let you use rfm69hw in a nrf24 socket. That could be an option. Search openhardware.io for it..

[pepson]

Ok i find:
https://www.openhardware.io/view/16/NRF2RFM69

very thanks

[pepson]

What software is for file kicad_pcb ?
I download this but i can not open this file by this soft...
http://kicad-pcb.org/download/windows/

Or in which file is write project PCB ?

[LastSamurai]

@pepson The *.kicad_pcb file should be the pcb, the *.sch file the schematics.
You could just use the schematics to remake my project by yourself though and learn kicad on the way. Otherwise the suggested adaptor seems to be the easiest solution.

[pepson]

@LastSamurai

But in soft kicad i dont have option to open this file... kicad can only open *.pro

[pepson]

This PCB will also available to buy it as i can buy PCB to converter NRF to RFM69 ?

[LastSamurai]

@pepson said:

I am not sure if I understand your question. I am not selling the pcbs but you can buy it from dirtypcbs and support me. I guess you should be able to use it with the converter though I never did. Be sure to check dimensions first!

[pepson]

But on dirtypcb what type file i must upload to give cost ?

[LastSamurai]

A zip with the gerber files. The version 1.3 that I used is already in their store though: http://dirtypcbs.com/store/designer/details/7078/867/mysensors-rgbw-controller-v1-3

[pepson]

Hmm a littlebig cost same PCB. Can you show me it how it looks in Domoticz ?

[LastSamurai]

@pepson What do you want to know about domoticz? It looks like every other RGB switch in domotizc depending on your used theme, just google it

[pepson]

But is any chance to implement also button as in fibaro rgbw ?

[LastSamurai]

@pepson I don't understand?!

[pepson]

Buttons to controlling leds red gren blue and white.

[LastSamurai]

@pepson Still not sure what you mean. If you want hardware buttons you can add those to the node (I did not). Everything else is part of the controller software which I don't control. You can always use something other than domoticz. But lets not spam this thread with that anymore please

[niek]

Will this board works with an APA102 ledstrip? And, I'm new to custom boards, how can I simply order a couple of this boards?
EDIT: i'm too fast, found this link: http://dirtypcbs.com/store/designer/details/7078/867/mysensors-rgbw-controller-v1-3
so my second question is already be answered!

[LastSamurai]

@niek APA102 are adressable leds, right? My led controller only supports "analog" leds controlled by pwm. At least without some modding.

[AWI]

@niek an apa102 strip contains internal logic/ driver circuitry so it can be controlled direct from arduino power pins. No mosfet needed. Take a look at the FastLED library to control these strips.

[CoolSaet]

I am trying to compile this project with the 2.1.1 library, but I keep getting the errors: the 'MyTransportNRF24' does not name a type.
As far as I can see, it seems that the type is nowhere defined in the libraries.

[LastSamurai]

@CoolSaet Yes that is because the sketch you are using is still from MySensors 1.5. I already updated the sketch to Version 2 in November but forgot to push the changes to github.
Here is a newer version that should work with mysensors 2. Only the (non)linear fading is still not working 100%.

PS I also updated the text of the openhardware.io project

[CoolSaet]

@LastSamurai Thank you very much for the update. That seems to have done the trick.

[Sergio Rius]

@LastSamurai The gerber files on Dirty PCBs are the mosfet corrected ones or the wrong? I just ordered some and now I've this doubt.

[CoolSaet]

@Sergio-Rius
I ordered the pcb a few months back on dirty pcbs. That one had the MOSFET pins connected wrong, but it wasn't that difficult to turn them an discribed in the post. I am not sure if a correct one is available.

[Sergio Rius]

@CoolSaet Thankiuu! I'll try not to mess anything.

[LastSamurai]

@Sergio-Rius I am pretty sure the version 1.3 from the store still has the pins rotated (= wrong but you can fix it as described). There is a fixed version of the gerber files in my github repo that is linked to this project though. I just haven't ordered them from dirtyPCBs yet so they are not in the store (as I am still using the rest of the old ones).

[Stuart Middleton]

Thanks, @LastSamurai, I went and compared the DIrty PCB files with the v1.3 ones on OpenHardware.IO and they are indeed different. It looks like the DIrtyPCB link is out of date and still has the error on them.
@Sergio-Rius would be very grateful if you could update those files

[Sergio Rius]

@Stuart-Middleton Unfortunately my boards are already made and shipped. They made them in just a day (Sunday) and didn't have me time to rectify my order.

[Stuart Middleton]

@Sergio-Rius Oh well, it doesn't look too hard to adapt for the error.

[LastSamurai]

@Stuart-Middleton It really shoudn't be. Just follow the pictures in the project. There are also updated project/gerber files in my github for anyone wanting to order new ones. Once I have used all of the Version 1.3 ones I will order new ones from dirtyPCBs and add the link here.

[LastSamurai]

@Jan-Gatzke Did you ever manage to get your non-linear fading to work? I used the predefined values from your sketch and added them to my newer one but whenever I use that the sketch stops working and only rubbish is shown on the serial port.
Here is my new version: github

[Jan Gatzke]

@LastSamurai

Yes, I did! This sketch is working for me:

/**
  Based on the MySensors Project: http://www.mysensors.org

  This sketch controls a (analog)RGBW strip by listening to new color values from a (domoticz) controller and then fading to the new color.

  Version 1.1 - Added save/restore of values to/from controller, removed non linear fading code
  Version 1.0 - Changed pins and gw definition
  Version 0.9 - Oliver Hilsky

@Jan-Gatzke Thanks, I'll try that later although it doesn't look much different from mine. May I ask why you are using V_VAR1/2 types in your sketch? And why you send answer messages? Are you using home assistant (thats the only one where this is need imho)?

[Jan Gatzke]

@LastSamurai

I am using Domoticz. This was the only way reading initial values from the controller. Directly requesting the value of a child did not work for me. Meanwhile MySensors support in Domoticz seems extremly bugy and uncomplete to me. I am going to give OpenHAB2 a try.

[LastSamurai]

@Jan-Gatzke Ah ok nice to know. I am facing the same problem. RGBW is not that well supported in domoticz. I am currently trying to switch to openhab2 but having some problems with my RGBW nodes there too. Development on the plugin seems to be very active though. If you want to follow the discussion have a look at the forum thread here or on github
Once I got everything up and running in openhab I'll post an update here.

Meanwhile the newest sketch from my github should work with Home assistant too.

[Sergio Rius]

I just assembled my first OH! My... board and realized that the V2 sketch doesn't work for me.
Anyways I'm posting a sample sketch for testing the board:

#define RED_PIN 3
#define GREEN_PIN 5
#define BLUE_PIN 6
#define WHITE_PIN 9

#define ON 100 // Please, don't burn my eyes
#define OFF 0

#define ON_INTERVAL (3*1000ul)

void setup() {
  // Setting pins to output and low is not required for analogWrite.
    Serial.begin(115200);
}

void loop() {
    analogWrite(RED_PIN, ON);
    Serial.println(F("**RED**"));
    delay(ON_INTERVAL);
    analogWrite(RED_PIN, OFF);
    analogWrite(GREEN_PIN, ON);
    Serial.println(F("**GREEN**"));
    delay(ON_INTERVAL);
    analogWrite(GREEN_PIN, OFF);
    analogWrite(BLUE_PIN, ON);
    Serial.println(F("**BLUE**"));
    delay(ON_INTERVAL);
    analogWrite(BLUE_PIN, OFF);
    analogWrite(WHITE_PIN, ON);
    Serial.println(F("**WHITE**"));
    delay(ON_INTERVAL);
    analogWrite(WHITE_PIN, OFF);
}

[LastSamurai]

@Sergio-Rius Nice to hear! And good idea with the test sketch.

What exactly did not work with my sketch? I would really like to fix it (for others too).

[Sergio Rius]

@LastSamurai I'm using Domoticz. With your sketch, turning on and off worked.
But whenever it had any rgb value, the white light was always 100% on. The RGB leds where all three lit at a time and never more than 20% but slightly responded to dimming control.

The above code from @Jan-Gatzke works flawlessy. Even turns the white leds on when reaching the white band on the gradient.
Only I would like it to not turn off the color leds until the selected color is totally or almost white, so we could white-wash the selection.

Oh, men... soldering those mosfets turned around was so difficult. I recommend the next who buys boards to use the new designs.

Give me some time and I'll give a turn to the sketch. But I'm still working on the "water-heating-solar-controller", and still have to assemble the energy monitor board, and do something with the meteo board.

[Sergio Rius]

@LastSamurai I have some doubts on this code, can I ask you?
The change between color values is done by a fade, and I understand that you don't want a linear change but an exponential one. Right?

One doubt i have is that I'm seeing that the fade is accomplished using a conversion array. So you are doing variable steps depending on the difference of value for each channel. Wouldn't be preferable to always take the same amount of time/steps doing the change?

Wouldn't be better to divide the difference for each value on the same steps and then doing the transformation. Then could be fixed without an array.

Sorry if I wrote something wrong. My english it's not so good.

[Jan Gatzke]

@Sergio-Rius

The problem with the linear fading was that a value of 100 almost looked the same as 150. So the goal was to make the fading look more linear. The logarythmic calculations needed for this cannot be done on an atmega 328p. (I tried it)
This is why I calculated the values with MS Excel and put them in an array.

Making the fading process alway take the same time would be nice. Feel free to post your implementation.

[Sergio Rius]

@Jan-Gatzke @LastSamurai I've been playing with the formula of the blog post written in comments on the sketch and I see that this isn't something trivial.
I think the code in the post has a misconception, that using 0-255 he missed that the graph data is not related to time, but pwm value.

So a fixed table for conversion between pwm value and appreciated light has to be built. And you also arrived to this conclusion seeing the array.
I'm generating the array on the fly using the formula with 256 steps.
(In the blog code there's a bug caused by the mean of zero in intervals and the formula that causes max value to being reached. You have to sum one to interval before using on the formula.)

I'm now trying to separate a loop for traveling the array that compensates for in between values so it can handle smaller steps->variable interval.

Sorry. Just thinking out loud.

[Sergio Rius]

I've been working on an sketch for this board. Somewhere in the path I started adding functionalities and it ended in a library. Perhaps it's way overkill, but I thought that could be easier add it to NodeManager like that.
It's based on the work done here and some more ideas around the network. Thanks to LastSamurai for the board and code and also to Jan.
You can find the sources there: https://github.com/SergioRius/RGBWDimmer

This thing includes a serial manager that I use myself, but you can remove it and delete all the code for debugging, and perhaps add yourselves if necessary.
Just clone the repo or download and install as a zip library on Arduino IDE.
The example works for the OH! MySensors RGBW board as is.

It's very self explanatory in the code, but in essence:

• It can be used stand-alone or with mysensors
• You simply send to the commands and the class does all for you.
• Uses a non blocking system for the fading.
• Configurable fading time and resolution
• Several configurable fading curves
• Option for gamma (brightness + hue) calibration.

I'm currently debugging the fading curves equations other than linear, as the arduino mcu capabilities are tight and it's so easy to overflow it. Also I'm doing a program for calibrating the hue (arduino with leds and a rotary encoder for manually adjusting), so for now gamma only compensates brightness. You can change the values if you prefer. I'll be a good idea to lower the white channel.

It still lacks some memory optimization, but for now I'm scared about overflows. I got one of those and it was a two days nightmare and I had to revert to ints to get something running.
I'll soon add a stand alone sample and port to NodeManager.
For the while, for using it alone the minimal it's:

#include "RGBWDimmer.h"
RGBWDimmer myDimmer(1, 3, 5, 6, 9);  ///< id (to remove), Red Pin, Green Pin, Blue Pin, White Pin

bool JustDontBlockLoop = true;

void loop() {
  if(JustDontBlockLoop) {
      myDimmer.setNewValues(255, 0, 150, 0);  ///< RGBW decimal values. If you prefer hex, use setNewValuesHex
      myDimmer.StartFading();
      JustDontBlockLoop = false;
  }
  myDimmer.loop();
}

I hope you like it. And if you have any idea for adding functionality, please tell me.

[Sergio Rius]

I updated the repo for being easier to download and install.

[LastSamurai]

Wow nice! Might take me some time, but I will take a look at your code (and maybe add some of its features back to my sketches if that fine with you).

[Sergio Rius]

@LastSamurai Yes, of course.
Just a question. How did you make the "values curve"? You said in excel and perhaps a graph... did you manage to change graph values and update data in any way?

I've made the sketch for adjusting the gamma values, something with a Serial monitor menu that allows for increasing and decreasing the channels in real time. And adjusted the greens for a better hue (orange being orange, not a greenish yellow) but now I do't know how to adapt the curve.
I refuse to modify the 255 values by hand.

Now I'm making a case for 3d-print. Where do I have to post it, there or in a separate post? I read anything about posts becoming entries at hardware.io and ¿build?

[ThetaDev]

Do you really need an external voltage regulator for this module? I mean the Arduino Pro Mini has its linear regulator already built in. You can only draw about 100ma from it, but wouldn't that be sufficient for the micro, radio and the mosfet gates?

[LastSamurai]

@ThetaDev Maybe you you could get away with it but especially the radio is very sensitive concerning the power supply. Cheap pro minis often use very cheap regulators too and then this might become a problem.
I also wanted to support the high power version of the NRF and that definitly needs more power than provided by the onboard regulator.

[pepson]

https://www.openhardware.io/view/16/NRF2RFM69#tabs-design

[LastSamurai]

I never tried that but as far as I know you have to tell Mysensors to use a different kind of radio by adding a define like:

#define MY_RADIO_RFM69

Just do a quick search on this forum though

[pepson]

And your project works also with Home Assistant ?
Can you show how it looks in your automation ? Which controller you use ? (Domoticz or other)
And on MySensors 2.2.0 this also works ?

[LastSamurai]

I only had Home Assistant installed for some days (did not really like it at the time) so I can't tell you that it works 100% but it did back then. You have to add some strange additional messages but I tried to integrate that into my code.
I am using my RGBW controllers with openhab 2 in one location and with domoticz in another. As it is controlled by MySensors it works (and looks) pretty much like any other mysensors node. Both installations run on 2.2. Hope this helps

@lastsamurai
Very thanks for info. I try build and test with Home Assistant.

[Sergio Rius]

Mmmmm... How much have you pushed this board? I mean, in terms of load.
I just had one fail at me and I'm trying to understand what component may have been the weak link.

It was driving a 5m white stripe when it turned himself off and on again, but although the light was still on the node was down. I took it out and almost burned my hand. Not the mosfets, but the arduino and radio. Nothing seems bad (components good looking, arduino seems to start) but as soon as you apply 12v, even without load it starts the barbecue.

It seems that the mosfets are good to 4,2Ah if I understand it. So what would be the boards specs?

[gohan]

Have you checked the voltage on the arduino?

[Sergio Rius]

@gohan As you suspected, it was 12v.

[gohan]

No wonder why it got hot, poor little arduino

[Sergio Rius]

@gohan Yeah, but what is not that intiutive for me is why when load increases in the mosfets side, the ams regulator goes away.

Anyways, no one knows what max led strip length is this board good for?

[gohan]

https://www.openhardware.io/view/559/LED-RGBW-Controller

You may also consider this one

[LastSamurai]

@sergio-rius A little late, sorry, but that depends on the mosfets you are actually using. I am driving ~5m strips of white leds with most of my controllers and they don't even really get hot.

There is also a big(ish) update from my side concerning this project: I have designed, 3d printed and tested my own case for the controllers and they work great. I have just added the stl files and some images to the project page!!
For now this project is done from my side. The controllers have been working great for the past 2 years but due to the "huge" (~1s) delay with my Mysensors network (with signing and openhab on a raspi) when switching the leds I am currently testing some MQTT and wifi based RGBWW controller boards as an alternative.

[pepson]

Hello
How long led strips in meters i can connect to this device ? What max power led strips support it ?

[pepson]

Why on 5 picture POWER MOSFET IRLM2502 is other side solder than on picture 9 ?

[pepson]

Hi
I build this project but i want use it with radio RFM69HW and controller Home Assistant. But it not working with Home Assistant. Not connect with gateway on my RPI3b+. Other node with this radio connect ok. I dont know why ?Radio works and show this:

I found one bug in your project PCB. Pin from radio nae IRQ should be connect on PCB to pin 2 ARDUINO. But it is not connect. Also when i use radio RFM69HW i also need connect PIN 2 Arduino to pin DI00 on radio RFM69HW. This should be correct... Now pin 9 from radio is not connect to any pin Arduino.

On RFM69HW all works ok. In previus post my radio is fix.

Hi
Is any chance to implement in sketch option to Node after connect power go to state OFF. Now it go to ON. In situation when power lost and come back all leds will be ON.

and is any chance to implement in your sketch option to add manual button to enable LEDS color WHITE ?
Any color i want to setup by gateway but on the wall i want mount switch to enable color white and also to disable.
Please add this if you can... In sketch setup pin on which button works and also color which should be turn on....

@aramko at first, he shared a link with the preloaded board on dirtypcbs (http://dirtypcbs.com/store/designer/details/7078/867/mysensors-rgbw-controller-v1-3).
If you want to upload the files by yourself, you have to zip all the files and upload them.. take a look here under "ordering" (https://dirtypcbs.com/store/pcbs/about)
