Smart pricing probably seems like a god idea,... But it is not. Airbnb makes money when your place is rented out. By that logic alone, one would think that the higher rate you receive, the higher commission they get, therefore, smart pricing recommends a high rate with a high booking possibility....
That's not exactly what they do. Airbnb wants to be viewed as the lower cost alternative to hotels.
When you turn on Smart Pricing, Airbnb recommends a rate that might seem high to you but is actually meant to be lower than comparable Hotels.
The best solution for automatic pricing or "dynamic Pricing" is to subscribe to the likes of Pricelab, Wheelhouse, Beyond Pricing,... I promise you your rate will go up, and your revenues will go up. The only thing that might go down is your occupancy... But then that only means less work.
