Documentation
Everything you need to set up, understand, and run Boat & RV Guardian — from your first sensor to a fully protected rig.
Boat & RV Guardian watches your boat or RV — an anchor alarm that alerts your people if you drag, a bilge alarm that reports the second water rises, a security zone that flags theft, and battery, shore-power, and climate monitoring around the clock — on affordable off-the-shelf Shelly and LinkTap hardware. The app works locally on your vehicle’s network for free; optional hosted plans add the away features.

New to Guardian? These three pages take you from an empty box to a monitored vehicle.
Quick start
The shortest path from unboxing to live monitoring on your boat or RV.
How it connects
Two pictures that explain the whole system — aboard vs away, and every way to get the vehicle online.
Hardware setup
The supported LinkTap and Shelly devices, what they cost, and how to provision them.
Using the app
A tour of the app’s main views and the everyday workflows you’ll actually use.
Watch & protect
The alarms Guardian is built around — where the vehicle is, whether it moved, and the water that shouldn’t be there.
Anchor alarm
The two-ring drag watch: free aboard on every plan, watching from the cloud on paid plans.
Location & security
GPS sources, the theft security zone, presence modes, cameras — and location sharing on the way.
Bilge & flood alarms
The battery sensor at the low point that sleeps for years and reports the second it matters.
Water control & safety
On a city-water hookup: why every valve open carries a hard limit, and the automatic shutoff on top.
Core concepts
How the rest fits together — alerts, history, and sharing.
