If i wanted to control a 3way smart light (rockers only) what’s the best solution

Is just neutral and ground enough to power it?

Definitely not. You need Line and neutral or neutral and load if Line is from load to power up a smart switch.

As @Navat604 pointed out, you'll need line as well and just to clarify what it means, you'll need power (120 V coming from the breaker), neutral (also coming from the breaker), and ground. If you need any help identifying the connections, feel free to reach out to our support for detailed wiring guidance.

Thanks! Yeah no trouble IDing them. I was hoping the voltage on neutral was just enough to use it as a button.
