Off-Grid Guardian Base Hub
The hub. Protects against break-ins, leaks, freezing and a dying battery bank - and keeps working with no internet at all.
Wire it to the 12 to 48 volt batteries you already have, or run it from any USB-C power source. A built-in siren sounds the moment a door opens. It senses movement and tilt, so you know if your trailer is being jacked up or towed. On-board temperature and humidity sensors warn you before pipes freeze or the inside starts cooking, and two relay channels can run a fan or a small heater on their own. It watches your battery voltage and tells you before the bank goes flat. Four sensor inputs let you add more doors, windows or a leak probe, and one of them doubles as a moisture probe. Arming, the siren and all automation rules run locally, so connectivity adds alerts and remote control but is never required for protection. No remote support fee.
-
Someone opens a door
A built-in siren goes off the moment a door, window or tongue box opens, loud enough to make an opportunist leave. You get a message at the same time.
-
A leak starts spreading
Water damage is slow, quiet and expensive. Put a probe under the sink or by the water heater and you hear about it in minutes rather than finding the subfloor soft months later.
-
The temperature turns dangerous
Set your own thresholds and get a warning before pipes freeze or the inside starts cooking. Two relay channels can run a fan or a small heater on their own, without waiting for you to act.
-
The battery bank runs down
It watches the voltage of the bank it is powered by and tells you before it goes flat - so a failed charger or a parasitic draw does not end with a dead bank and spoiled food.
-
Somebody moves the trailer
Movement and tilt sensing picks up jacking, hitching and towing, so an attempt to take it registers as more than just a door opening.
-
The internet is nowhere to be found
Arming, the siren and every automation rule run on the hub itself. Connectivity adds alerts and remote control - it is never required for the protection itself.
