Fibaro RGBW module and RGBW remote controller

[Guest berga_s]

Hi,

I would like to add a RGBW led strip to my daughter's room.

I would like to manage the RGBW led strip both by HC2 interface and also by RBGW remote controller. Anyone have already done it?

I found this RGBW remote controller:

I also read the Fibaro RGBW controller manual but I' not sure if I'm able to do what I would like.

Below I have tried to make a connection schema that shoul be done, but I'm not sure if it's correct or not.

Is this schema correct and work both from RGBW wireless controller and HC2?

I'm not sure with the on/off functionality from Fibaro controller becasue the V+ is coming from the RGBW wireless controller.

I would be interested to know the outcome of this, reason being that my LED strip, which I have bought a RGBW Fibaro controller for also flashes and strobes - which i want to retain being able to do, but don't believe it will be possible to control this functionality though the fibaro module, therefore i need to also be able to keep the control of the original controller alongside the RGBW module.

berga_s, we have not tested such solution. It really depends on kind of outputs this 2nd controller has. If they are open collector outputs it might work, however the logic probably would be opposite e.g. setting color to 100% red would turn red off. Also RGBW may be not able to detect them as analogue inputs without some kind of external filter. So this case is quite complicated and highly depends on specification of the external controller.

Thanks j.nowacki.

What you mean with "If they are open collector outputs"?

Assuming that the output of 2nd controller is ok, should this diagram connection right?

berga_s, open collector outputs means that it can have ground potential or high impedance. Just like our RGBW. Assuming that outputs are open collector we still have an issue of detecting state on inputs of RGBW Controller. If frequency of signal on 2nd controller outputs is too low, there might be some kind of external low-pass filter needed. And even then the logic will be inverted - when 2nd controller will set some color to 100%, the RGBW will set it to 0%. Additional external circuit with transistors will be needed for sure. We did not test such solution and do not recommend it in any way, these are just some loose thoughts on this topic.
