A firmware update for Samsung SmartThings Hub 2018 and 2015 models was released to customers on Monday, December 9th. This release version (28.12) is a hotfix that includes a fix for pairing for certain Z-Wave devices.
On Monday, December 2, we released Hub firmware version 28.11 for the Samsung SmartThings Hub 2015 (Hub v2) and Samsung SmartThings Hub 2018 (Hub v3). Following this release we identified an issue where adding some legacy Z-Wave devices would result in these devices failing to report state changes. This could lead to inaccurate device states reported within SmartThings. Z-Wave Plus devices and devices added prior to the 28.11 Hub firmware update are unaffected.
We are working to release a firmware hotfix to address this issue. In the meantime, we encourage users to delay adding legacy Z-Wave devices that are not Z-Wave Plus until after the hotfix is released and to exclude impacted devices.
How do I know if I am impacted?
Starting Monday December 2, if you added a Z-Wave device which is not a Z-Wave Plus device, you may be impacted. Z-Wave Plus devices are newer devices and can usually be identified by a Z-Wave Plus logo on the box or the device itself which looks like:
If you believe you recently added one of these devices, you can verify it is impacted by looking at the raw description on the device details page of the SmartThings IDE. Login at https://account.smartthings.com, click My Devices, and click on the device you recently added. Check the Raw Description and look for cc:. If you do not see “5E” listed but do see “85”, your device is impacted. We recommend removing/excluding the device until the hotfix is released.
In the below example, the Raw Description contains cc:20,25,86,80,85,72,71. Note that we do not see 5E but we do see 85 as part of the “cc” section. This is an example of a device that may fail to report state changes and will need to be excluded and re-added after the hub firmware hotfix.
What should I do if I am impacted?
We are actively working to release a hub firmware hotfix to alleviate the issue. We advise that you remove/exclude any impacted devices until the hotfix is released. For assistance in excluding devices, see How to exclude Z-Wave devices.
