The control system
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.
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.

Core, add-ons, devices
What a system is made of.
Three levels, bought in this order. The Core is the only part every system has. What you add after that follows from what you want to control.
The Core
Every system has oneThe computer that runs everything, mounted out of sight and powered from the leisure battery. One per vehicle. Pick the tier that suits the build: each one runs the same Nomad software, and the tier sets how much it can take on. The first year of the Support Plan is in the price.
Core Pro
Adds vehicle data, air conditioning, heating and presence
£999
Core Vision Coming soon
Adds speech control and camera intelligence
£1499
Core AI Coming soon
Adds conversation with the van
£1999
Add-ons
Buy the ones your build needsThe Core is the brain. These are its hands and ears. Each one exists to control a specific set of devices, so work down the list picking off the things you want to control. Plenty of builds only need a few.
Screen
To see and control the system in the van
A habitation tablet, a cab display, or just your phone.
Relay and I/O module
To switch anything on a plain 12V wire
Water pump, lights on a switch, fan, step. Six or eight channels, WiFi, Ethernet or PoE.
£44.95
Zigbee adapter
To reach wireless zigbee sensors without new cabling
The usual answer on a retrofit, where running wire through finished walls is not on.
from £50
Bluetooth adapter
To reach wireless sensors without new cabling
The usual answer on a retrofit, where running wire through finished walls is not on.
from £20
LED controller
To dim and colour LED strip
A relay can only switch a strip on and off. This is what makes it dim.
from £25
LED Addressable controller
To control LED strip effects
A relay can only switch a strip on and off. This is what manages effects.
from £25
Van Level
To read how level the van is
Van Level Pro for pitching up.
Tank Level
To read water tanks using resistance float senders
Tank Level Pro for fresh and grey
Router and switch
To give the van internet, position and a wired backbone
A MiFi or your phone's hotspot will get the van online. What a proper router adds is position for Radar and a tidy wired lane for screens and modules, which is why most builds fit one.
Vehicle Telematics
To read engine and vehicle data
Plugs into the OBD2 port.
Your devices
Mostly already in the vanThe kit that does the actual work. Sensa does not replace any of it and we do not need you to buy ours. The tag on each one says how it reaches the Core, which is what tells you whether you need an add-on for it.

These are groups rather than the full list. See every individual device Nomad can talk to, with photos and the detail on each.
What the tags on level 3 mean
- Direct Speaks to the Core on its own. No add-on needed.
- Needs a relay A plain 12V load, so it needs a relay module to switch it.
- Needs an adapter Joins over Zigbee or Bluetooth, so the Core needs the matching adapter.
- Needs a sensor board Read by one of our level boards rather than by the Core directly.
- Needs a controller Dimming and colour need the LED controller. A relay can only switch the strip on and off.
Which adapter a device needs depends on the device: a rooftop aircon usually speaks Bluetooth, a door sensor Zigbee. Sensa Studio works that out for your build, device by device, and gives you the list.
Rough prices, to give you the shape of a build. The full pricing, and which bits we sell.
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
- The instincts that watch your own kit: low battery, shore-power still plugged in, the dog still aboard
- Scenes and routines that act on what's in the van
- All your data, stored on board
Needs a connection
Through the internet
- Instincts that lean on the outside world, like a heads-up when you're low on water and passing somewhere to fill up
- 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.
