@Nicole1128 , Ha! Good question! And I'm with you on having Airbnb's tool monitor my prices for me - as long as they're going up!
In my experience, Price tips and Smart Pricing are opposites.
Before I used Smart Pricing, I would look at the tips, and they always, always, always wanted me to lower my price by a LOT. I ignored them.
I finally turned on Smart Pricing a few months ago, and it has raised my prices across the board. My minimum is set to what I would normally charge, NOT Airbnb's minimum. And so far so good.
If price tips are raising your price - I say go for it. But I would worry about using both, because I get the impression that after you turn Smart Pricing on, if you fiddle with prices individually, it gets glitchy. Some have said Smart Pricing has let people book instantly at a price below their minimum.
And I've found another benefit - using tools like Smart Pricing and Instant Book have driven my listings up in the rankings. Maybe price tips would do the same.
If you're happy with the price Smart Pricing comes up with, go for it, because as you say, it's easier than manually revising prices all the time.
