Shelly RGBW2 Homey integration

Hello everyone. I have an AC-DC converter (230V AC to 12V DC), switch, 1x LED stripe (with just 2 outputs ("+" and "-") so it's not RGBW), Shelly RGBW2 and Homey with Shelly App installed.

I used schematic on the picture. I'am able to connect Shelly into Homey (I see devices "Shelly RGBW2 White1", "Shelly RGBW2 White2", "Shelly RGBW2 White3" and "Shelly RGBW2 White4"). I think one of them is control for my LED stripe. I connect my LED to "W" channel so it's maybe White4 (that's not important).

Der Inhalt kann nicht angezeigt werden, da Sie keine Berechtigung haben, diesen Inhalt zu sehen.

After all I can't control my LED. LED doesn't light. What's wrong? But it works using Shelly app (outside Homey) .

Can somebody help? Thanks.

Okay I solved my problems.

Hi Tomas

I have the same problem using the 24v supply. I am able to include in the homey app. With the first action in the homey app the LED bar switches off and doesn’t respond anymore.

Works fine with Shelly app

How did you solve your problem?

Regards

Correction: it works fine in the direct web interface. Doesn’t work in the Shelly app either
