Dear all,

I am using many RGBW2 devices in color type (RGBW LED strips) and White type (4 white LED strips) and all I will describe below I have tried with many firmwares but in all of them behaviour is same. Wiring is same as manual of RGBW2 is showing so dont need to post here...

and in all of them I used RGBW2 input

Setup as momentary:

And by this input button I am able to On (short push) and Off (short push) and Dim (long push UP and Down).

I have 2 questions regarding dimming by switch behaviour :

1. In RGBW2 (color mode, I have connected RGBW LED strip) input I can dim by long push (up and down) all is working to me but if I have some color and want to dim up it is increasing color brightnes but also white channel brightnes ? Is that correct? Why it is not increasing only color without white ? Is it possible to change?

Maybe is not clear my question so here is detailed description of this behaviour:

I have rgbw2 and rgbw led strip set in shelly app red color 30% and white channel 0%. I short push button (on rgbw2 input) led strip light on as set red color 30% and white channel 0%.If I push button and keep pushing now, red color go up to 100% but also white channel go from 0% to 100% also.I release button now and both are 100% red and white.

I push button again and keep pushing and same scenario but opposite red go down to 0% and same white go down to 0%.

I will never come back to 30% red color and 0% white by button so I have to open shelly app and setup it again...

So me question is why is white channel dimming also and why it is not dimming only red color please?

2. In RGBW2 (White mode, I have connected 4 white LED strips) input I can dim by long push (up and down) all is working to me but why it is dimming all 4 white LED strips. There is no way to setup that RGBW2 input switch will controll only channel1 or channel1 and channel 2 for example please?

I have tried to change button type to detached but if I change it in channel1 for example it change in all 4 channels.

Is that working same way to you please?

Many thanks for each reply and help.

Dear all,

I have wrote to shelly support to ask regarding dimming RGBW2 dimmer by API and reply is:

It is not possible.

RGBW2 does not have enough memory unfortunately.

So due to memory there is no way to dim RGBW2 dimmer by API as it is possible in normal dimmer by this command:

http://192.168.xxx.xxx/light/0?dim=cycle

In this case there is no way to implement even in the future...:( very bad

Thanks

Thanks @SebMai for reply and help!

You mean I should make request to shelly support to add this function?

So currently there is no way to dim (only On and Off) RGBW2 by other shelly devices (by API) only local input on RGBW2 module is able to On and Off and dim?

I would like to connect motion senzor PIR (not baterry shelly motion senzor but small 24V and output of PIR connect to RGBW2 input) to RGBW2 and also some push buttom to be able to ON, OFF and dim light.

Any suggestion?

Thanks for each help!
