Make Any Vehicle
Smarter.
Control lights from your phone. Monitor batteries and water tanks. Get alerts when something's wrong. All without needing cell service.
What You Can Do
TrailCurrent adds intelligence to your vehicle. Here's what that actually means.
Control From Your Phone
Turn lights on and off, adjust brightness, set thermostats, and manage accessories from your phone, tablet, or a wall-mounted touchscreen.
Pre-Trip Prep
Cool the fridge before you pick up from storage. Check that the jacks are up, the hitch is secure, and the trailer lights are working—before you drive.
Travel Alerts
Get notified if a cabinet opens, a door shifts, or anything changes while you're driving down the road. Catch problems before they get worse.
Storage Security
Know if someone enters your vehicle while it's in storage. Get location alerts if it moves. Monitor conditions like temperature and humidity.
Power Management
Track solar production, battery levels, and power consumption in real time. Automatically conserve energy while boondocking off-grid.
Works Offline
No cell service? No problem. The system creates its own WiFi network. Everything works at a remote campsite, on the water, or in your driveway.
How It Works
Modular hardware that plugs into your vehicle, connected by a small onboard computer.
Add Smart Modules
Plug in only what you need. A power controller for lights and accessories. A GPS tracker. Air quality sensors. A battery monitor. Mix and match.
The Vehicle Computer Ties It Together
A small onboard computer connects all the modules, runs dashboards you can view in any browser, and stores offline maps for navigation.
Control From Anywhere
Use your phone, tablet, or a wall-mounted display. At camp, connect over the vehicle's WiFi. Away from the vehicle, connect through the cloud.

Fully Open Source.
Keeps Getting Better.
TrailCurrent is 100% open source. Every hardware design, every line of code, every document. You can inspect it, modify it, or build it yourself.
Because it's open, the system improves over time through software updates that arrive wirelessly—no trips to a dealer, no service appointments. New features, bug fixes, and improvements just show up.
And because you own the hardware and the data stays on your vehicle, there are no subscriptions, no cloud fees, and no one harvesting your data.
No Subscriptions
Everything runs locally on your vehicle. The optional cloud is self-hosted. No monthly fees, ever.
Your Data Stays Yours
Vehicle data lives on your hardware. No telemetry harvesting, no tracking, no third-party access.
Over-the-Air Updates
Modules update wirelessly. New features and fixes arrive without physically accessing the hardware.
