RV between trips
The rig lives in the driveway or a storage lot between weekend trips. Plugged in or not, mostly you just want to know it's ready to roll on Friday — not discover a dead battery when the trip is supposed to start.
What can go wrong
The small stuff that turns a getaway into a repair day.
Dead house battery on Friday night
You arrive to load up and the bank is flat. The trip starts with a jump box instead of a campfire.
A slow leak while it sits
A water line, water heater, or pump fitting weeps inside a cabinet for weeks between trips, quietly doing damage.
The battery tender stops tending
Storage-lot or driveway power fails and the charger goes with it. The bank drains and you never got a heads-up.
You left the water on
The pump got left running, or the city-water connection stayed pressurized — a small oversight with a big downside over a few weeks.
How Guardian covers it
Each risk maps to something that ships today, with the plan tier it needs called out honestly.
Know the battery before you drive over
The Shelly Plus Uni reports the house bank's real state so you top it off in advance instead of finding out at the campsite. Automatic on Basic+, manual refresh on Free.
Make a spigot connection safe
If the rig stays hooked to water, the LinkTap valve makes that safe: every open is volume/duration-limited, and flood sensors close it early — locally with the app open, via the cloud on any tier.
Catch weeps in the wet bay
A Shelly Flood Gen4 under the wet bay or water heater catches slow leaks while the rig sits between trips — and the away push reaches you on any tier.
Confirm the pedestal is really delivering
The Shelly PM Mini confirms the lot or driveway outlet is actually powering your charger — not just plugged in.
A cheap always-on link for storage lots
No Wi-Fi where you park? Your sensors sip data, so a cheap LTE hotspot on an inexpensive SIM keeps you informed for a few dollars a month — and many gateways add GPS, so you also know the rig is where you left it.
The setup
Off-the-shelf hardware, bought once. The core app is free.
Recommended hardware
- Shelly Plus Uni — house battery bank~$25
- Shelly Flood Gen4 — wet bay / water heater~$30
- LinkTap valve + Gateway — if stored connected to water~$135–160
- Shelly PM Mini Gen3 — confirm shore power~$25
Start with the Plus Uni and a Flood Gen4 (~$55) and add the valve if you store connected to a spigot. For a storage lot with no Wi-Fi, see the connectivity guide for cheap always-on options.
Recommended plan
Free is workable — Basic if you'd rather be told
If you'll open the app and check before each trip, Free covers it — including the away push when a flood sensor trips. Basic ($3/mo · $12/yr) adds automatic monitoring and a month of hosted history, so a dead tender finds you on Tuesday, not Friday.
Every vehicle can try one month of Basic free, started from the app's Account view.
