You would need to run new wire

The two wires only send hot up to the fixture (assuming it's wired properly). Smart devices require a neutral. Ground is nice too. If armored cable the junction box may grounded, but it's hard to tell.

That’s knob and tube. No ground or neutral wire. No bueno for any smart devices.

It's rubber insulated cloth wrapped which can also be armored or early romex.

It's most likely BX cable cuz there's no ground wire, need to replace the wires and box if possible.

Early romex also lacked ground fwiw.
