Zwave switch needed to replace 2 wire (Insteon 2474D)

Folks,

I'm having a hard time finding anything to replace a two wire smartlab insteon 2474D.
Literally this appears to be the hotwire from the light fixture, brought into the box.

Can anyone recommend some specific models?

If I have to, I can go the relay route, but I still have to be able to power switch to control it, or go with a battery powered switch...
If smart labs was able to do this, then why is it so hard to find one in a Zwave flavor?

Now the outlet that is next to the switch is on a different breaker (#22, I believe), the switch is on breaker (#17).

Hi Benjamin,

Thanks for the info.
I don't know if I understood your question correctly but if you are looking for a 2 wire solution then maybe the Z-Wave Fibaro FGD-212 is the solution for you?

"It may be connected to two-wire or three-wire configuration"

By two wire are you referring to the live hot wire coming from the light fixture and a second switched hot going back to the light fixture? Plus I see a ground wire in your photo. I am unfamiliar with Insteon. I use Z-Wave. If the Insteon is a smart switch requiring electricity to operate they might have used the ground wire as equivalent to a neutral. Since you also have a receptacle in the box you should be able to use that neutral to connect to a Z-Wave switch. Neutrals are not specific to a certain breaker. They all terminate normally on a common neutral bar. As long as you don’t overload the neutral wire you should be okay. The consumption on the neutral for the smarts of the Z-Wave switch should be very low.

Not true anymore. Arc Fault breakers have the neutral connected to the breaker, then a pigtail from the breaker connects to the bus bar. See https://www.protoolreviews.com/what-is- ... t-breaker/

Also, I believe that crossing neutrals outside of the breaker box is a code violation, but I don't have a copy of the code to reference that. I do know that the electricians who wired my house were very careful to split the neutrals on the fixtures where a fan and a light were on different switches (and breakers). This is rare, but does happen, especially where panelized lighting systems are used and multiple lighting circuits are controlled from a single multi-dimmer box on a dedicated breaker.
