Hi all. First post so please be gentle.
I have an Eachen two-gang smart wall switch wired no neutral (with capacitor) connected to existing bathroom lights which works perfectly. It's also wired to a Sonoff Mini R4 Extreme connected to LED lights. I want the LED lights to switch on when the bathroom lights switch on (and vice versa). The Mini R4 works separately on my phone via Ewelink as well as on the Mini R4 itself (physical button). The switch is installed inside the wall and the rest of the components are in the ceiling / attic / roof cavity. The Mini R4 is set to Edge switch mode which works in my example I wired.
How I wired it:
I have a video showcasing the example I wired today works. I could share it if required. Ignore the white cable. I only used it to power the example.
The wiring diagram I used for the mini R4.
I wired it together with the existing lights of the bathroom so that L1 switches on both the Mini R4 and the bathroom lights:
This is the wiring diagram for the Eachen switch:
The Eachen's first gang (L1) doesn't trigger the Mini R4 in any way.
Any help or advice will be much appreciated.
Thanks,
R
