Due to the lengthy nature of this SmartThings Hub update, we are going to be performing this update in a different fashion than normal and rolling the update out in groups over a number of days. We are also going to share a bit more technical detail than usual - feel free to post your questions below and we will do our best to answer all of them.
First of all, this update will be rolled out over multiple days. You will receive an email at least 24 hours prior to the update being applied to your Hub; the email will contain a time window when your update is expected to be applied. Please refrain from asking when the update will be available for your Hub - due to the quantity of updates, we won’t be able to respond to these requests. To verify your Hub has updated, please see Is my Hub’s firmware up to date?
On to the good stuff - what makes this update different? Up to this point, updates to the Hub have been performed in an incremental fashion; this means that each update builds upon the other updates that came before it. The advantage was that updates could be smaller since only the changed portions of the system need to be transferred each time.
The new update is a full image. Now, when your Hub receives an update, it will contain all the information needed to run SmartThings software. This first full image may take as long as 15-30 minutes. However, going forward, the switch to a new update will be almost instantaneous - beta users have reported not even noticing that the update happened. This means that there is no longer a small window where power loss could corrupt your Hub. It also means that if a file becomes corrupted on your Hub, it can be detected and a valid image applied. In the worst case of a catastrophic failure, the new update includes a “golden” image of the Hub firmware that can be used to attempt a recovery.
This update also includes:
- Additional diagnostics for detecting and repairing memory corruption, and reporting failing hardware early.
- The ability to enable firmware updates for all devices except lights or all devices including lights. Lights will turn on automatically after they update so you may not want to enable automatic updates.
- Additional firmware updates for OSRAM lights (US only)
- Welcome Code and factory reset capabilities
- Numerous stability improvements and bugfixes.
We hope you agree that the above benefits of this update justify the extended downtime.
