Good question @pswilson1. There are two main components to the Tempest announcement: a) revised weather station hardware, b) new AI-powered forecasting technology. Also remember that expected delivery is not until Feb/Mar/Apr of 2020.
Regarding the revised weather station hardware, from a functional performance standpoint, the new Tempest does essentially the same thing in most of the same ways. Think of it like this: you just bought the 2020 Ford Mustang. Then Ford announces that there will be a 2021 Mustang released next year. Both are Mustangs, both drive and look amazing, but the 2021 has a slightly different stereo package and isn’t available for delivery until March. ( iPhone 12? But, I just bought the iPhone 11! )
As noted, all WeatherFlow station owners will benefit from the new AI-powered forecasting.
If you want to return the station you purchased a week ago and instead pre-order Tempest on Kickstarter for delivery in 2020 you are certainly welcome to do so, but the functional difference would be nominal, and the wait significant.
Current owners do not need to upgrade unless they really really want to (but do go ahead and tell your friends & family to buy one!). The new Tempest hardware device will be backwards compatible with your existing HUB, and we intend to offer a discount deal to existing station owners once we’re ready to deliver in 2020. Hope that clarifies. It’s always odd to introduce new versions…but that’s how progress and innovation is made.
