The only new feature a user might notice is the ability to adjust the brightness of the LED, although we haven’t built that into the apps yet, so it’s not something you’d notice at all yet.
The other significant feature in the latest Hub is the ability to update the firmware on the Tempest device. This was super helpful during the field test but now that the firmware is mature, it should not be an issue going forward. Note that the AIR & SKY have not needed a firmware update since they were released. In the unlikely event that we need to update the firmware on your Tempest, but you don’t have the latest hub, we’ll figure out a different way to take care of you!
