Shelly1 without Neutral make a DIY bypass circuit hack!

I wanted to see if it was possible to use the standard Shelly1 without a neutral. I know that it is possible to do so with the Shelly1L , you just require a special bypass unit. So I came up with a experimental circuit that allows the standard Shelley 1, to be used without a neutral connection, behind the light switch. My circuit hack is basically a "custom load bypass" that specifically works with the smaller Shelly1. The circuit is very inexpensive and easy to make yourself. The best thing about it, is that NO soldering iron is required. I honestly think the circuit is worth further investigation. You guys are welcome to give it a try and give me some feedback.


00:00 Intro
00:28 Shelly1 v Shelly1L that requires a load bypass for it's NO-NEUTRAL function.
00:40 Maybe it's possible with a clever circuit hack to use the Shelly1 without a neutral.
01:37 Making the basic "No-soldering version" of the circuit.
05:32 Let's look at the wiring diagram with its component values for the test circuit.
05:46 Wiring everything up, and test the basic circuit with Wi-Fi and manual switch operation.
07:59 Using heat shrinks tubing to insulate all the exposed Live metal parts.
08:39 Improving the basic circuit to add safety and reliability. By adding a inrush current limiter/ over current protection.
09:29 Safely test your circuit by putting it in line with an old school incandescent light bulb. Stop the Magic Smoke from escaping.
10:40 Don't Fear The soldering iron. Make a much neater version with modules and flexible wires.
11:51 let's install it on a mock-up, of a possible real life installation example.
13:54 Some worrying pictures of the Shelly bypass, burnt out, that could be a possible concern!
14:52 If you would like to know in detail ,exactly how the circuit functions you should watch the sonoff mini R2 video. It's basically identical to this circuit.
