Samsung SmartThings: Scenes Disappeared After App Update... | digitalhomefaults.org

Technical Background:

SmartThings Scenes rely on cloud execution even when local control is enabled. Scene definitions are stored in the Samsung cloud and synchronized with the SmartThings Hub via API calls. App updates can disrupt the authentication tokens or API endpoints used for this synchronization. Rogers Ignite and Bell Giga Hub firewalls might also interfere with the cloud connection if incorrectly configured. DHCP lease renewal issues can affect the SmartThings hub's IP address, disrupting its network communication.

Symptoms:

After updating the SmartThings mobile application (Android/iOS), user-configured Scenes are no longer visible or executable within the app. The SmartThings hub LED may exhibit a blinking green or yellow pattern indicating cloud connectivity issues. App logs may show 'Scene Unavailable' or 'Cloud Service Error' messages.

Possible Causes:

Corrupted app cache after the update.
Authentication token invalidation requiring re-login.
Cloud service outage or maintenance impacting Scene availability.
Incompatible app version with current hub firmware.
DHCP lease renewal failure resulting in a new IP address for the SmartThings Hub without updating the cloud registration.
Interference on the 2.4GHz Wi-Fi band from neighbouring devices or appliances, particularly during Canadian winter when more devices are used indoors.

Solution:

1

Force close the SmartThings app and restart your mobile device.
2

Clear the SmartThings app cache and data (Android) or reinstall the app (iOS).
3

Log out of the SmartThings app and log back in using your Samsung account credentials.
4

Verify that the SmartThings Hub has a stable internet connection. Check the hub's IP address in the SmartThings IDE and ensure it matches the DHCP lease assigned by your Rogers Ignite or Bell Giga Hub. If not, reboot the hub.
5

Check the SmartThings IDE (Integrated Developer Environment) to confirm that the Scenes are still defined in your account. If not, restore from a backup if available.
6

Update the SmartThings Hub firmware to the latest version via the SmartThings app. Ensure a stable power supply during the update process.
7

If using a custom DNS server, temporarily switch back to the ISP's default DNS (Rogers or Bell) to rule out DNS resolution issues.

Safety Warning:

Do not attempt to disassemble or modify the SmartThings Hub. Secure your Samsung account credentials and enable two-factor authentication. Be aware of phishing attempts targeting SmartThings users. Physically secure your SmartThings Hub to prevent unauthorized access. Monitor network traffic for unusual activity indicating a security breach.

Prevention:

Regularly check for SmartThings app and hub firmware updates. Assign a static IP address to the SmartThings Hub within your Rogers Ignite or Bell Giga Hub settings to prevent DHCP lease issues. Periodically back up your SmartThings configuration using the SmartThings IDE or a third-party tool. Before major app updates, document your existing Scene configurations in case a rollback is necessary. Test scenes after each hub or app update.

Expert Tip:

If Scenes are still missing, try creating a new Scene with a simple action (e.g., turning on a single light). This can sometimes force a synchronization between the app and the cloud, restoring the missing Scenes. Check the SmartThings community forums for reported issues and workarounds specific to the latest app update.

Frequently Asked Questions

•How do I assign a static IP address to my SmartThings Hub on a Bell Giga Hub?

Access the Bell Giga Hub's web interface. Navigate to the 'Connected Devices' section. Locate your SmartThings Hub (identified by its MAC address). Assign a static IP address within the DHCP range but outside the dynamic allocation pool. Save the changes and reboot the SmartThings Hub.

•Where can I find the SmartThings IDE?

The SmartThings IDE (Integrated Developer Environment) can be accessed through a web browser at graph.api.smartthings.com. Note: Samsung is migrating to a new platform. Access is being phased out. Check the SmartThings community for the latest status.

•My SmartThings Hub is offline after the update. What should I do?

First, check the hub's power supply and network cable connection. If those are fine, try power cycling the hub by unplugging it for 30 seconds and plugging it back in. Check your Rogers or Bell modem/router for internet connectivity. If the hub remains offline, perform a factory reset (consult the SmartThings documentation for the reset procedure) but be aware this will remove all your devices and configurations.
