💬 OH MySensors RGBW Controller
-
I have tried to get some kind of non linear fading by calculating the values for 256 steps using Excel and putting them in an array. The result is pretty good. Please test and share your opinion. ;)

Thx for the info. This comes 24 hours to late. :joy:
-
@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.
-
I dont know software kicad... and can i please you to help me for changing it to radio RFM69HW please ?
-
Ok i find:
https://www.openhardware.io/view/16/NRF2RFM69very thanks
-
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 ?

@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 said:
This PCB will also available to buy it as i can buy PCB to converter NRF to RFM69 ?
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!
-
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 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 I don't understand?!
