Lake Display docs

Setup and troubleshooting notes for the small connected display. These docs match the links shown on the device screen when something needs attention.

Setup

Plug in the device and wait for the setup screen.
Join the Wi-Fi network named Lake Display Setup if the device is in setup mode.
Open http://192.168.4.1, or after Wi-Fi is saved, open http://lakedisplay.local.
Save Wi-Fi first, then save the data source settings.
Use the sample tool from your normal internet-connected Wi-Fi network to confirm the data source returns a value.

The setup page on the device is local to your network. The public site is https://lakedisplay.com.

Wi-Fi Problems

If the screen says STALE, WiFi lost, WiFi failed, or WiFi reconnecting, the device cannot reach your network.

Try this

Confirm the router is powered on and the device is within range.
Open the setup page and re-save the Wi-Fi network name and password.
Make sure the network supports 2.4 GHz Wi-Fi if your router separates bands.
Power-cycle the device after changing router settings.

The display retries Wi-Fi automatically. It should not keep showing an old lake value as if it were live while Wi-Fi is unavailable.

Water Data Problems

If the screen points to /docs#data, the device reached Wi-Fi but could not use the configured data source.

Common causes

The time series name, office, unit, or API URL has a typo.
The public data service is temporarily unavailable.
The data source returned no recent values.
The returned JSON shape changed or could not be parsed.

Public water data can be delayed, stale, renamed, or missing. A clear stale/error state is safer than a plausible old number.

Firmware Updates

The setup page can check for and install firmware updates. Keep the device powered while an update is being applied.

If an update fails, leave the device powered and try again from the setup page.
If Wi-Fi drops during an update, reconnect Wi-Fi first and then retry.
If the device will not boot or cannot be reached, it may need USB recovery flashing.

Support

This product is still in active prototype development. Keep a note of what the small screen says, the firmware version shown in setup, and the configured data source when reporting problems.
