Wyze Switch wiring again - ground

I have old 2-wire circuits in my house. The neutral is in the box where I want to put my Wyze switch, but there is no ground wire.

Will the switch work?

(Curious that the Support page doesn’t have an option for the Switch, even though I know there is an installation video somewhere.)

It will work without a ground connection, but they recommend one. The entire case is plastic though, so not much of a shock hazard.

Support Pages for the Switch are here:

If the box is metal and grounded there’s no reason you couldn’t wire to it?

How do I know if the box is grounded?

The house is 100 years old, and the wiring is probably almost that old.

You put a lightbulb or tester to it and see if it completes a circuit from the hot wire.

OK, I’ll give that a try, thanks.
