Revinor Posted September 2 Share Posted September 2 Is there a proper way to wire Shelly Plus 1 (or Plus 1PM) behind an official two-button wall switch, with one button controlling Plus1, second one being connected to RGBW PM? I'm not trying to fit them both in the same socket, RGBW PM would be near the led strip. Easiest way would be of course to use two single buttons, but it is a waste of real estate on the wall for a room which has just 1 led strip and 1 main light. Seems that having just one ground wire is going to be a problem here? Quote Translate Revert translation?

Members thgoebel Posted September 3 Members Share Posted September 3 (edited) This is a principle diagram for the wiring: Wiring of the lamps at the outputs of the Shelly devices is not depicted! Prerequisite is the black gadget with 4 wires (2 black wires at one side and a red and a black wire at the other side) which is delivered with Shelly RGBW2. This module separates the high voltage side (2 black wires) galvanically from the low voltage side (red/black). And please be aware you‘ll need a separate DC power supply for the Shelly RGBW PM!

Revinor Posted September 3 Author Share Posted September 3 Thank you very much! Unfortunately, I have Shelly RGBW PM, not Shelly RGBW 2, so I haven't got any black box extras with it. Can it be purchased separately? Quote Translate Revert translation?

It would be nice to purchase this article separately! Quote Translate Revert translation?

Members thgoebel Posted September 4 Members Share Posted September 4 (edited) Thanks to @Olsche, who pointed out some difficulties with using the "black" addendum of Shelly RGBW2 in this circiut diagram: I did some investigations with my scope. Indeed, it is erratic to switch and dim with this arrangement. Reason for this behavior is the mains frequency which penetrates at the secondary side of the optocoupler in the black gadget: In steady state (at the left), the potential at IN-1 is 7,4V. Pressing the button pulls the voltage nearly to GND - but for roughly 7ms only. Thus, a pressure of the button generates some tens or hundreds of very short signals. This bothers the firmware. Same issue is with (the old) Shelly RGBW2, but amendment was made within the firmware of RGBW2 by debouncing the signal at terminal IN. A workaround is possible with a 4,7µF capacitor at the input: This smoothes the output of the optocoupler and guarantees a proper control with a push button. This is the curve of a button press of approximately 1 second. Dimming up was initiated while pressing the button. It would be brilliant to (a) amend the optocoupler gadget of Shelly RGBW2 with this capacitor (which would be very small using a SMD model), and (b) make available the optocoupler as a single purchase position. The additional capacitor will most likely not affect the behavior of the part if used with Shelly RGBW2. If desired, I would double-check this...
