The original Wink Hub has a rather uninspired design. It's basically a square with rounded corners, and on the back there is only a power port. Wink updated the look of the Hub 2, making it a bit taller and sleeker looking. The power port has moved to one of the sides, which allows you to place it on a shelf easier, and on the back, it also has an ethernet port.
Odds are you'll be putting the hub somewhere that it isn't visible regularly, so the design isn't going to be the most important selling feature here. The addition of the ethernet port to the Wink Hub 2 allows you to hardwire it to your modem instead of wirelessly connect to it. This makes for a stronger, more secure connection between the hub and your internet.
When it comes to supported services and devices, the two hubs are nearly identical. Both will allow you to use compatible Zigbee, Z-Wave, and Alexa accessories. Each hub has built-in Wi-Fi and Bluetooth, but the Wink Hub 2 does offer Bluetooth Low Energy, which the original does not. You can automate tasks for connected devices on both hubs through If This Then That (IFTTT).
The Wink Hub 2 has Thread support and a security chip to ensure that the software is not tampered with on the device. It also brings along scheduled tasks and Robot, which allow you to complete multiple tasks with just a single tap.
One of the key differences here is that the Wink Hub 2 has eight times the amount of RAM that the original one did, which means that it can complete tasks much faster. Some side-by-side comparisons have shown that it can complete some routines in under 3 seconds that took upwards of 15 seconds on the original hub to complete. This is a huge difference, and something you will definitely notice regularly.
No one wants to wait upwards of 15 seconds to have the hub turn on your lights or power off a smart outlet that is connected to it. With the upgraded internals, Wink was able to move some of the processing from its servers to the hub itself, allowing it to be more reliable and faster.
Which should you buy?
If you are looking to buy your first Wink Hub today, the Wink Hub 2 is the way to go. You get the newer, sleeker hardware, which has a few new features over the previous version. It also includes some technology that can be taken advantage of in the future, which puts you in a better position to use it long-term.
Already own the original Wink Hub? It's a little harder to recommend the Wink Hub 2 as a needed upgrade over the original, though if you feel the limitations of the hub, then an upgrade is obvious. The apps are the same, the main features are very similar, and both are very competent smart home hubs that work with tons of different hardware.
