Ok so switch lincs require a neutral. The neutral wire forms a part of the live circuit along with the hot wire.

Use ground as neutral for smart switch. Neutral wires can be added by two ways. Leave ground as ground everywhere do not cheat neutrals or you negate the ground safety function. The key to creating a smart switch that works without the neutral loop is to make r1 the perfect resistance. Just the load wire comming in and out. The bare wire is called the ground wire. The smart switches are mostly used with the neutral wire.
There are smart switches that do not require a neutral. R1 needs to restrict the current enough so that the light bulb doesnt turn on when the switch is off. Or put the aeotec g2 assume its a switch module in the receptacle box and leave the wallswitch on all the time. If it were as simple as making r1 the correct resistance to make sure the light cant turn on when the switch is off it would be a fairly simple problem to solve. It works just fine. However due to.
Neutral wires are used to complete any circuit and the same concept is used in the smart switches to complete the circuit with the help of the neutral wires and operate the switch remotely at any instant. By design they bootleg some neutral return current on the ground wire. However the neutral and ground wires serve two distinct purposes. Best practice is to pull a neutral to each location that can use it. Seems like a hack but how dangerous is it really. So i connected the switchlinc neutral to the copper ground wire.
In two of my switch boxes i have no neutral. At the same time it needs to let enough current through so that the switch can power itself. Like the neutral wire the ground wire is also connected to an earth ground. However if they are legal and listed they are tested to limit the bootleg current to some tiny amount that is considered safe by ul. The copper grounds and the neutrals are both terminated to the same bus in my breaker box so it does not seem like a bad idea.
