Hi everybody,
After months of research, I’m wiring up my first Shelly switch (exciting!). I thought I got it right but the light just flickers rapidly and I can’t see any wifi network or bluetooth device. Toggling the light switch 5 times doesn’t do anything either. It’s Shelly 1+ PM.
Can you please see any obvious errors in how I wired it up? I assume there is one and it also explains the flicker.
Thanks!
This doesnt look wired correctly and inwould say if you do not know what you are doing you risk causing injury to yourself or starting a fire. Please get an electrician to do.
Main issues i see are
Way too many issues here tomrisk continuing yourself.
Everything basically. You shorted the output 
There’a a good chance that this permanently damaged the shelly. It’s also a good way to have it catch fire. What probably saved you from more damage is the fact that you incorrectly powered the shelly in series to your light, which indirectly limited the short current.
And that bare exposed copper carrying a phase…
As the poster above said, it’s probably best to get an electrician for this. 120/240 V circuits are dangerous and you could seriously injure yourself or damage your home if you don’t know how to handle this.
What country are you in ? Whats the color coding of the wires?
Depends on the country, but black is typically a phase.
Thank you for the frank replies, @msp1974 and @HeyImAlex! Now I can show this (the way I wired it up) to my uncle - an electrician - that laughed at me when I said I wanted him to wire up everything, saying I should be capable and safe doing anything past the electrical enclosure.
Either way, the black wire is, indeed, a phase, but it was not live. I checked that out before I did any wiring. I also had no intentions of leaving it like that, nor to leave the long exposed ends on those cables.
The question is, do I remove the image or update it, so nobody accidentally uses it when they google “wiring shelly properly”? I am afraid I basically did the same mistake as I just Googled for some images, not checking the content and wired it up following the first one that seemed fine.
Alright, so here is what happened there. I took down all switches to figure out how they were wired up.
This was a three-way light switch. What’s in the picture is one end of the chain of the tree switches. Here we call this kind of configuration 6+7+6 configuration, as can be seen below.
To get a smart module to work with a configuration like that, one has to place the module at the other end (the one closest to the load), where neutral is more likely to be found. There, it’s easy to connect it like almost any basic switch, see below.
I’ll leave the original photo here, and hopefully, no one will use it out of context.
P.S. That Shelly module survived the torture and now switches on a small towel heater in the bathroom.
