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 is a monitoring and protection system for boats and RVs. It pairs affordable off-the-shelf smart-home hardware — LinkTap water valves, Shelly sensors — with a cross-platform app that works locally on your vehicle’s network for free. Optional hosted plans add remote access, alerts, and history when you’re away.

Guardian is currently pre-alpha. It already does everything documented here, but expect rough edges, and read roadmap labels carefully — anything marked Coming soon is planned, not shipped.
