How the Sensa system works

One small computer, your van's existing systems, and screens where you need them. Everything talks through the brain and everything keeps working without it.

The whole system on one page: your kit on the left, the brain in the middle, your screens on the right.

Your systems

The van keeps the kit it has. Batteries, heater, pump, lights, cameras, router. Sensa doesn’t replace them, it connects to them, each by whatever it speaks: a wire, a radio, or its own protocol.

The brain

A Raspberry Pi 5 or an AI-capable Mini PC on the Vision tier, mounted out of sight, running everything locally: the dashboards, the instincts, your routines. Silent, low-power, and boots with the leisure battery.

Your screens

Three views of one system. A habitation screen for living, a glanceable cab screen for driving, and your phone for when you’re away. Same brain behind all of them.

Four ways in.

Wired I/O

The physical layer

Follow a wired first principle if possible, especially on new builds. Compact input/output modules switch and sense the 12V world, pumps, heaters, lights on switches, tank senders. Hard-wired, van-grade, no batteries to die.

Wireless

The wireless mesh

Wireless devices are important, especially for a retrofit. It may not be possible to run lots of new wires. Sensors and lighting join over Zigbee and Bluetooth, door contacts, vibration and motion sensors, LED controllers with no extra wiring through your walls.

Direct integrations

Systems that speak for themselves

Kit with its own smart controllers, e.g. Victron, Teltonika routers all talk to the brain natively, so you see real data, not a bolted-on approximation.

The van's network

An Ethernet backbone

Screens and wired modules ride the van’s own network, kept on a separate lane from your laptops and streaming, tidy, fast, and easy to fault-find.

The question that matters

Works with what you have.

Sensa is built around the kit vans actually carry and it wires in alongside your existing controls, never instead of them. Every switch, every panel, every knob keeps doing its job with Sensa or without it.

Where things run

In the van first. The internet is extras.

Runs locally — no internet needed

In the van

  • Every control, every dashboard, every switch
  • All instincts, including the shore-power check
  • Scenes, routines and instincts, all of it, offline
  • All your data, stored on board

Needs a connection

Through the internet

  • Radar live maps and nearby points, using the van's GPS
  • Weather and solar forecasts
  • Checking in from your phone, away from the van
  • Remote support — with your consent, logged
  • Software updates, proven on our own fleet first

You lose the map, not the heating.

The foundation

Built on Home Assistant. Proudly.

Under the hood, Sensa runs on the world’s largest open automation platform, battle-tested in millions of homes, with thousands of integrations. We harden it for life on wheels: vehicle-grade configuration, one tested image on every van, and updates proven on our own fleet before they reach yours. Open foundations mean no lock-in and your data stays yours and when you outgrow what the screens offer, the whole platform is underneath, waiting.
