What do the LEDs on Aeotec Smart Home Hub mean?

LED Color	LED activity description	Function detail
	Alternating Green and Red	Hub is ready to be claimed (with or without internet), you have 30 minutes to start the setup process.  If you miss this window for setup and your hub is blinking blue, just unplug power, replug your hub, then wait 1 minute.
	Solid Blue	Hub is claimed and connected to the network, but has no internet or server connection.  Make sure to check SmartThings status webpage to ensure that SmartThings cloud is operational. If it is, try swapping between WiFi and Ethernet.
	Blinking Blue	There is no Ethernet or WiFi connection. This can happen if you allow Smart Home Hub to timeout its setup process.  Simply unplug your hub, and then re-plug your hub. If using WiFi, try connecting it to Ethernet.
	Blinking Magenta	Downloading update
	Solid Magenta	Applying update
	Solid Green	Hub is connected
	Blinking Green	Hub is in pair mode (searching for device)
	Fast Blinking Green	Hub is in Z-Wave exclusion mode
	Blinking Yellow/Amber	Factory Reset in process
	Solid Yellow/Amber	Factory Reset process complete
	Blinking Red	An Issue occurred during bootup, wait at least 2 minutes to see if it’ll resolve itself.  Try an extended power cycle to resolve this issue. (wait a minimum of 6 minutes before powering up the hub again.)
	Solid Red	Hardware issue, wait at least 2 minutes to see if it’ll resolve itself. Power cycle the hub (attempt this a few times), if the issue does not get resolved, contact support.
