How it connects

Two pictures explain the whole system: what happens on the boat, and how the boat reaches the world.

Aboard and away

Guardian runs two independent paths at once. Aboard, the app talks to your hardware directly over the vehicle's own Wi-Fi — readings and taps are instant, and none of it needs the internet. Away, each sensor reports to the Guardian cloud on its own, and the cloud does the watching: alerts to everyone on the vehicle, and — on city water with a paid plan — closing the valve by itself.

How Guardian works Sensors and the water valve on the boat or RV talk to the app directly over the local network, and report to the Guardian Cloud over the internet. The cloud pushes alerts to your phone anywhere and closes the valve automatically on a flood alarm. ⛵ On board Off-the-shelf sensors on the vehicle's Wi-Fi 📍 GPS · anchor & security 🔋 Battery monitor ⚡ Shore power 🌊 Flood sensors 💧 Water valve (city water) 📱 Your app, aboard Live readings and control on the vehicle's own network — no internet needed ☁️ Guardian Cloud Alerts, remote view, history — no hub hardware required 📲 You, anywhere Push alerts on every plan · remote view · everyone alerted Local Wi-Fi — instant, works offshore & off-grid reports in seconds push Flood alarm?

Two independent paths: aboard, the app talks to your hardware directly; away, the cloud watches, alerts, and acts. Lose the internet and local protection keeps running.
The two paths fail independently, and that's the point: lose the internet and the aboard alarms keep working; leave the boat and the cloud keeps watching. The only thing that needs both dead is silence — and the cloud notices quiet vehicles too.

Everything above assumes the vehicle can reach the internet somehow — and there are more ways to do that than most people expect. All of them end at the same cloud; they differ in cost, reach, and whether they keep working after you walk away.

Ways your boat or RV can reach the Guardian cloud ⛵ 🚐 Your vehicle sensors, valve, cameras — all on its own Wi-Fi Pick ONE uplink → (they all end at the same cloud) 📶 Marina / campground Wi-Fi free where it reaches — sensors sip data 📡 Cellular router (recommended) always-on for ~$1–15/mo of data — and its built-in GPS powers the anchor watch 📱 Your phone's hotspot fine while you're aboard — nothing reports after you leave 📦 Guardian hub COMING a Pi, Docker box, or the desktop app collects everything 🛜 Guardian-managed router COMING reports for every sensor, GPS, and a locked-down network 🏢 Shared hub at the marina COMING long-range sensors reach the office hub — no Wi-Fi aboard at all ☁️ Guardian Cloud one destination, whatever the path 📲 You & your people alerts anywhere, on every plan
Every path ends at the same place: the Guardian cloud, and then your phone. Solid paths work today; dashed ones are on the roadmap.
  • Marina or campground Wi-Fi is free where it reaches — Guardian's sensors use so little data that even weak shared Wi-Fi usually carries them. See the connectivity guide for cheap ways to extend its reach.
  • A small cellular router is the recommended always-on answer: ~$1–15 a month of data, works in the mooring field, and its built-in GPS is what powers the anchor alarm and security zone with no extra hardware.
  • Your phone's hotspot works while you're aboard — good for a weekend afloat, but nothing reports after you and the phone leave.
  • Coming: the Guardian hub (a Pi, a Docker box, or the desktop app collecting everything and forwarding it), a Guardian-managed cellular router with the same job built in, and shared hubs at marinas where long-range sensors reach the office and no Wi-Fi is needed aboard at all.
