How Wavepane compares.
Tide displays fall into roughly four categories before Wavepane. Each has trade-offs — some look like real art and miss on accuracy; others nail accuracy and look like a gadget. Wavepane is the first that doesn't make you pick.
| Analog tide clocks | LED lighthouse art | LED-grid WiFi displays | Generic Amazon e-paper | Wavepane | |
|---|---|---|---|---|---|
| Accuracy | Drifts hours/year; needs resetting | Decorative, not based on real data | Live NOAA / WorldTides | Varies; often unverified | Live NOAA / WorldTides, minute-precise |
| Coverage | Reliable only on Atlantic-style coasts | N/A (decorative) | Anywhere with WiFi | Varies | Every populated coast on Earth |
| Power source | AA batteries; mechanical drift | Plugged into the wall | Plugged into the wall | USB or wall power | Battery, 6 months per charge |
| Display | Single hand on a dial | Decorative LED pattern | LED pixel grid | Small e-paper, usually 4-color | 7.3″ color e-paper, six-ink |
| Updates | Manual reset every few months | None | WiFi, automatic | Varies | WiFi, hourly, automatic |
| Subscription | None | None | Some require a subscription | Varies | None — uses free public data |
| Setup | Set the hand once | Plug in | App pairing + WiFi config | Variable; often complex | Scan a QR code, ~30 seconds |
| Aesthetic | Classic clock face | Decorative art piece | Tech gadget | Utilitarian | Modern art piece on the wall |
What's in each category
Analog tide clocks
Beautiful brass-and-glass clock faces with a single hand that rotates once per tidal day (12 hours 25 minutes). They model just the M2 lunar harmonic and ignore everything else — the sun, the wind, the local coastline geometry. The result drifts by hours over a year and only reads accurately on coasts with classic twice-a-day tides. They don't know where you are. Typical price range $40–$100.
LED lighthouse art
Decorative coastal pieces — sometimes nautical-themed table lamps, sometimes wall pieces — that use LEDs to evoke water or weather. They look beautiful, but they're not connected to real tide data. The "wave" doesn't move with your actual tide. Price varies widely with craftsmanship.
LED-grid WiFi tide displays
Pixel-art devices that pull live tide data over WiFi and render it on a small LED grid or matrix. Accurate, current, and global — the technology works. But the form factor is a tech gadget: bright LEDs, a power cable, designed to sit on a shelf or counter rather than hang as art. Most need a wall outlet at all times.
Generic Amazon e-paper devices
A scattered category of small e-paper displays repurposed to show tide data — usually 4-color, often 2.9 to 4.3 inches, often imported with thin English documentation. Some are excellent; some are essentially abandonware. Software varies. Setup can be involved.
Wavepane
The modern digital tide clock. 7.3″ six-color e-paper, the same display family used in high-end smart picture frames. WiFi-connected to NOAA in the U.S. and WorldTides globally, refreshed hourly, accurate to the minute. Battery-powered — six months on a charge from the same cable that charges your phone. The wave on the screen IS the tide; you don't read it, you see it. And its crest height isn't decorative — it scales with the live ocean wave forecast at your coast, so a stormy weekend reads taller on the wall than a glass-calm Tuesday.
