Troubleshooting

The Display's screen always tells you where it stands — start by reading the message, and the table below does the rest.

What the screen shows	What to do
"Set up over Wi-Fi" with the name of a network	The Display is in setup mode. Connect to the named network and open 192.168.0.1 (Chapter 5)
"No Wi-Fi" with "connecting to..." or a retry countdown	The saved network is out of reach or the password changed. Wait out the retries or redo the setup
"Device not registered" with a code	Registration has not completed yet — check that the network has internet access. The code is the UUID, which support may ask for
"Data source" with the portal's IP	No device configured yet. Open the portal and point to the source (Chapter 6)
"Waiting for data" with "retrying LAN/CLOUD"	The source is configured but has not answered yet. Check that the source device is powered on and on the network
"OFFLINE" in the footer	The source stopped responding. Check the source device and the network
Faded value with "last update"	The data has gone stale (20 minutes with nothing new). Usually an unstable network or a busy source device
The opening bar stopped at a step	The step where it stopped is the diagnosis: network, registration or device. Fix the named item and restart
Screen dark in the middle of the night	It is night mode with "screen off" enabled (Chapter 9) — not a defect
A sensor vanished from the rotation	Either it stopped being a favourite on the source device, or it is hidden in the portal, or it went silent for more than 20 minutes

If the problem persists, restart the device with the physical button — no settings are lost — and, if needed, contact support with the UUID at hand.
