Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
When your Samsung SmartThings Hub displays LED flashing or solid magenta and shows as Disconnected in the app while controlling connected lights, it is installing a firmware update. Do not unplug or reboot the hub during this stage and wait until the indicator turns solid green.
Safety first
Stop and check this first
- Do not unplug or reboot the SmartThings Hub while the LED is flashing or solid magenta; Samsung warns in TSG10007366 that the hub is updating during this time.
- Never open the hub, smart bulb, or power adapter housing (technician only), and leave any hardwired luminaires, wall switches, dimmers, or mains wiring to a licensed electrician; if the unit feels hot, looks swollen, smokes, or smells of burning, unplug it if safe and stop using it.
Safe checks you can perform
- Confirm the magenta LED state without unplugging the hub
- Inspect the hub firmware version in SmartThings Information
- Submit system log data through the SmartThings support menu
Leave these tasks to a qualified professional
- Do not attempt this professional task: Verify transition to solid green LED and check firmware in Information
- Do not attempt this professional task: Submit official SmartThings feedback with system log data attached

Confirm the magenta LED state without unplugging the hub
- Who:
- you, checking the front indicator on your Samsung SmartThings Hub without touching the power cord.
- How:
- verify the hub has power and observe whether the indicator is flashing or solid magenta while the SmartThings app shows Disconnected, keeping the unit plugged in without rebooting.
- Result that matters:
- allow the firmware update window documented by Samsung in TSG10007366 to finish safely.
- If the indicator switches to solid green once the upgrade completes:
- verify that your connected lights respond in the app.
- If the magenta light remains unchanged after an extended wait:
- proceed to check the hub firmware screen in the app.
- Evidence to keep:
- photo or short clip of the magenta LED and screenshot of the Disconnected status in the SmartThings app.
Evidence: SmartThings device does not respond or the status is disconnected or incorrect · Use multiple SmartThings Hubs
Inspect the hub firmware version in SmartThings Information
- Who:
- you, using the SmartThings app signed in to the location of your hub.
- How:
- open the Location drop-down menu at the top left of the SmartThings app, tap your SmartThings Hub tile, tap More Options (three vertical dots at the upper right), and select Information to view the firmware version.
- Result that matters:
- confirm whether the hub reports an updated firmware build and online status per TSG10007241.
- If the Information page shows the current firmware version and active status:
