💬 OH MySensors RGBW Controller
-
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/RGBWDimmerThis 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.

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

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).

@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 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. -
Hi
How i can modify sketch files INO to use it with radio RFM69HW with this adaptaer:
https://www.openhardware.io/view/16/NRF2RFM69#tabs-design -
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_RFM69Just do a quick search on this forum though ;)

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 :) -

Very thanks for info. I try build and test with Home Assistant. -
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? :thinking_face:
-
@gohan As you suspected, it was 12v.
-
@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?

@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.
