01 · Simple to reach
No app. Just your browser.
Your chart carries its own small web server. Open its address on any device and its control page appears, ready to use.
Its own Wi-Fi
The chart broadcasts a private, password-protected hotspot named for your chart. Join it and the control page opens by itself, the way hotel Wi-Fi does.
On your home network
Connect it to your home Wi-Fi once, and reach it from any phone or laptop in the house at an easy address like chart-12372.local.
Buttons on the frame
Two discreet buttons switch the backlight and the chart lights by hand. Guests never need a phone to enjoy it.
02 · Sunset schedule
Lights on at dusk, off at dawn.
Enter your ZIP code and your chart learns when the sun sets and rises where you live, recalculated every day through the seasons. It lights itself as the real lights come on along the water.
- On at sunset and off at sunrise, day by day
- A separate plan for each day of the week
- Up to four time windows a day, overnight ones included
- Hold the lights on or off any time; the schedule resumes on its own at the next change
An example week
03 · Live tide
Your harbor’s tide, in a single light.
One light on your chart is given over to the sea itself. It follows the tide at the NOAA station nearest you: its color tells you how high the water is, and its rhythm tells you what it’s doing.
- Warm red at dead low, through gold and green, to deep blue at high water
- A slow, deep breath at slack water; a quicker surge while the tide runs
- Height and direction shown in the app, refreshed every 15 minutes
- Very low
- Low
- Mid
- High
- Very high
A full tide in thirty seconds
04 · Light & mood
Set the glow to suit the room.
A ring of light set around the frame casts a soft glow onto the wall behind, while the navigation lights on the chart have a dimmer all their own. Bright for a party, low and amber for a quiet evening. Your choices are kept on the chart, even through a power cut.
- Frame glow in any color you like, at any brightness
- A separate dimmer for the chart’s navigation lights
- Every light keeps its true rhythm at any brightness
05 · Signature touches
A little theatre when it wakes.
Choose how your chart greets you each time it powers up: fifteen startup effects, from a lighthouse sweep to a storm rolling over the water. Preview any of them on the chart from the app before you choose.
Also: Spark · Nautical Dawn · Color Cascade · Morse SOS · Tide Pool · Fireflies · Sonar Ping · Reel.

Lights that are yours alone.
Beyond the official aids, your designer can add lights that tell your own story on the chart.
Home port
Your house, marina or mooring, marked with a light that breathes slowly in and out.
Wreck sites
Amber memorial strobes over historic wrecks: two quick bursts, then a quiet glow.
Morse lights
Signals that spell a letter, a name or initials in true Morse timing.
Hazards
A slow red pulse over a reef or shoal you know too well. It never quite goes dark.
06 · Made for you
Custom programming, if you have something in mind.
Everything on this page comes as standard. But the software on every chart is our own, written in our workshop, so we can teach your chart new tricks too. Tell us what you'd like it to do, and we'll tell you whether it can be done and what it would cost.
Custom work is quoted separately, and can be added when you order or later on. Added later, it arrives over the air (see below). Once it's installed, you control it from the same control page as everything else.
Lights with a story
Bring back a lighthouse that went dark decades ago, with its original characteristic. Mark the spot where you proposed, the cove where you learned to sail, or the route of a passage you made.
Days to remember
A gentle show on a birthday or anniversary, colors for the holidays, or a countdown to the first day of the season. Your chart can keep a calendar of its own.
More from the sea and sky
Beyond the tide: wind at the nearest buoy, water temperature, the phase of the moon, or a warning glow when a gale is forecast. If the data is published, a light can follow it.
Clubs, marinas & restaurants
Lights in your colors, a schedule that matches your opening hours, or a sequence for race day. A centerpiece that belongs to your place alone.
07 · Over-the-air updates
Delivered, and still evolving.
Your chart arrives, it’s on the wall, and you think: that light would look better in white. Or you wish it flashed like the real one at the harbor mouth, or you’ve had an idea for something new. None of that means sending it back. Your chart can be reprogrammed right where it hangs, over its Wi-Fi connection.
We make the change in the workshop, build a new version of your chart’s software, and send it to your chart alone. You press Install on the chart’s control page, and about a minute later it’s running the new version with all of your settings in place.

An update, sped up. Simulate a fault to watch the safety net work.
From our bench to your wall.
Every update goes through the same six steps, each designed so your chart is never left without software that works.
compile · bench testBuilt in the workshop
We change your chart's program, compile a new build stamped with its own build number, and run it on the bench before it goes anywhere.
per-device releasePublished for your chart
The build goes up to our update server, filed under your chart's own identity. It's made for your chart, and no other chart can see or download it.
owner-initiatedYou press Install
Your chart checks in once a day and shows a banner on its control page when something is waiting. Nothing installs until you say so.
encrypted · fingerprintedDownloaded & verified
The new build streams over an encrypted connection and is stored alongside the software that's running, then every byte is checked against its digital fingerprint.
60 s probationTrial run
The chart restarts into the new build, which has to run cleanly for a full minute before the chart will trust it.
automatic rollbackKept, or rolled back
Pass, and the new build becomes permanent. Stumble, and the chart switches itself back to the build that worked, and tells us so we can fix it.
Fixes & improvements
Updates that keep your chart working at its best cost nothing.
- Bug fixes, whenever we find one
- Enhancements and improvements to the chart's software
- Performance updates: smoother, faster, more reliable
Your changes & custom programming
Anything you ask us to change or add, quoted up front before any work begins.
- A different color or flash pattern for a light
- Brightness, timing and startup tweaks just for you
- Wish we'd made something differently? We'll change it
- New behavior and live data: wind, water temperature, the moon
- Calendar shows, bespoke sequences, and anything from Made for you
Under the hood
Your chart runs its own software, written in our workshop, with the update system built in from the day it ships.
Updates need the chart to be on your home Wi-Fi with internet. Its own hotspot keeps working without one; it just can’t fetch updates until it’s connected.
- Delivery
- Over the air, through your home Wi-Fi
- Connection
- Encrypted end to end
- Identity
- A unique key for every chart
- Integrity
- Digital fingerprint checked before switching
- Safety net
- 60-second trial, automatic rollback, and a backstop after repeated restarts
- Your settings
- Kept through every update
- Who decides
- You. The daily check only tells you; it never installs by itself
- Downtime
- About a minute, while the chart writes and restarts
- Version history
- Every build is kept, so any change can be undone
Questions
Good to know.
ChartGlo Connected comes with every lighted chart, at no extra cost.
Do I need to download an app?
No. The chart hosts its own control page. Open it in the browser on any phone, tablet or computer, the same way you would visit a website.
Does it need the internet?
Only for the live extras. The chart's own Wi-Fi hotspot works anywhere, even with no internet. Joining your home Wi-Fi adds the clock, sunset and sunrise times, and the live tide.
What happens after a power cut?
Your settings are stored on the chart, not in the cloud. When power returns, the chart reconnects, sets its clock and carries on with your schedule.
Can I still use it without my phone?
Yes. Two discreet buttons on the frame switch the backlight and the chart lights on or off. Everything in the app is optional.
Can it do something that isn't listed here?
Very likely. Every chart runs our own software, so we can program it to do something special for you. See Made for you above, or write to us with your idea.
Where does the tide come from?
From NOAA's tide predictions for the station nearest your ZIP code, refreshed every 15 minutes. You can also choose a different station if you prefer another nearby.
Will an update erase my settings?
No. Your schedule, colors, ZIP code, tide station and Wi-Fi are stored apart from the software and stay exactly as you left them.
What if an update goes wrong?
The chart holds on to the software that was working. A new build has to run cleanly for a minute on trial; if it doesn't, the chart switches back by itself and lets us know.
