Frequently Asked Questions

Why does my SmartThings hub keep disconnecting?
Frequent disconnections are usually caused by unstable internet connection, router issues, interference from other devices, or outdated hub firmware. Ensure your router is close enough for strong signal strength and check for firmware updates in the SmartThings app.
How long should I wait after power cycling my SmartThings hub?
Wait at least 30 seconds with the hub unplugged, then allow 2-3 minutes after plugging back in for full startup. The hub needs time to initialize all radios and reconnect to your network and SmartThings cloud services.
Will power cycling my hub affect my connected devices?
Power cycling temporarily disconnects all Z-Wave and Zigbee devices, but they should automatically reconnect once the hub comes back online. Device settings and automations are stored in the cloud and won't be lost during a simple power cycle.
What's the difference between network reset and factory reset?
Network reset (10-second button hold) only clears Wi-Fi and network settings while preserving device configurations. Factory reset (20-second hold) erases everything and requires complete setup from scratch.
