Control panels for campervans, motorhomes and boats
One system: a touchscreen panel and a few small wireless modules that feed it. Start with the panel, then add whichever parts of the van you want on screen - later is fine, with nothing to take back apart.
Help me chooseAnswer a few questions about your van and we will list exactly what it takes, and why. Often that includes things you do not need to buy.
Start here
The screen, and the brains behind it
The panel itself - a 5" or 7" touchscreen and a separate control board. Eight switched circuits, battery voltage and temperatures on its own; tank levels, state of charge, heating and dimmable lighting each come from a module you add when you want it. Updates arrive over the air after fitting.
From £400
including VAT
Replacing an existing panel?
If your van has a Sargent or CBE unit, there is a version that plugs straight into the loom already in it. No rewiring, no adapters, nothing to cut.
- Sargent EC155 plug & play Drops into an EC50 or EC51 panel opening, using the loom already in the van from £415
- CBE PC180 / PC210 plug & play Drops into a PC180 or PC210 panel opening, using the loom already in the van from £415
Then add what you want on the screen
Each one is a small module that talks to the panel wirelessly. Fit one now and another next winter - the panel already knows what to do with them.
-
Power Know what your battery is doing A shunt sits between your battery negative and the rest of the van, and counts every amp in and out. That is what turns a voltage reading into a real percentage - plus live usage, history, and how long you have got left. SavvyShunt from £120 -
Water Tank levels at a glance Fresh, grey and black water on one screen, plus the level in an underslung LPG tank - and a built-in driver for the gas solenoid, so you can isolate the gas from inside the van. SavvyTanks V3 from £90 -
Lighting Every light, dimmed and named Eight dimmable channels with names you choose - Kitchen, Bed, Awning - and scenes you set once and recall with a tap. Around 100 metres of traditional LED's in total, more than most vans will ever hold. SavvyLights from £120 -
Levelling Level, without the guesswork Two axes of tilt on the screen, with which wheel to lift and by how much. Set your own idea of level once - a slight pitch if you sleep better that way - and everything after that is measured to your setting. SavvyStance from £75 -
Heating Your Propex, on the panel Replaces the analogue Propex controller with the screen you already have - temperature, schedules, timers and fault information, plus LPG level and solenoid control in the same place. SavvyPropex from £125 -
Heating Your Autoterm, on the panel For Autoterm 2D and 4D heaters. Adds schedules, timers and readable fault information - and an Auto Heat mode that keeps adjusting the heater to maintain temperature rather than leaving it on one fixed setting. Autoterm add-on from £125
Accessories and spares
The parts that go with what you have already got - a probe per water tank, the valve that empties the grey from the screen, relays for anything over 10 amps, and the small things that turn out to matter once the panel is in.
-
TP-Link wireless 4G LTE router
£99.99Give the van its own internet, wherever it is parked
The panel needs an internet connection before the app can reach it from anywhere but the driveway. This mounts inside or outside the van, takes an ordinary data SIM, and gives the panel - and everything else on board - a connection of its own instead of borrowing your phone’s hotspot.
Needs: A SavvyVan3 panel, a Nano SIM with its own data plan, and either 12V or Power over Ethernet where you mount it
-
Tank probe
from £44Reads the level in one tank
One probe per tank, in the length that suits its depth. SavvyTanks reads up to three, so a van with fresh and grey needs two of these. Be aware these cannot be cut down, so measure your tanks first.
Needs: A SavvyTanks V3 module
-
Motorised drain valve
£45Empty the grey tank from the screen
Park over the drain, tap the screen or the app, walk away. A 12V motorised valve on the grey outlet, switched by a SavvyTanks relay or one of the panel's own switches.
Needs: A free switch on SavvyVan3, or a SavvyTanks V3 relay
-
Temperature probe
£8A second reading, inside or out
Every SavvyVan3 comes with one probe. Add another and you can see inside and outside at once, which is the pair most people actually want.
Needs: A SavvyVan3 panel
-
Soft-surface mounting plate
£10The only way to take the screen back off
A bolted plate for the 7 inch screen, for surfaces that will not take adhesive. It is also the one mounting method you can reverse later.
Needs: A 7 inch SavvyVan3 screen
-
200A high-current relay
from £20For anything drawing more than 10 amps
The panel switches 10A per channel. Winches, inverters, big pumps and water heaters want more than that, so they get switched through one of these.
Needs: A SavvyVan3 panel
-
240V solid state relay
£36Switch a mains circuit from the panel
For hook-up circuits - an immersion element, a mains heater or anything else 240v. The panel gives a low-voltage signal, the relay does the mains switching, and the two never meet.
Needs: A SavvyVan3 panel, and a mains circuit worth switching
Water heaters
Three, six or ten litres, off grid or on hook-up. The one range here we did not design ourselves - Pundmann make them, we sell and support them, and they run from the panel through a relay.
-
Pundmann 3 litre
from £322The small one, for a van that is short on space
Three litres, up to 65°C in about an hour. Single 12V rod if you are always off-grid, or twin rod if you sometimes have hook-up.
-
Pundmann 6 litre
£396Enough for washing up and a short shower
Six litres on twin rods, so 12V on the move and 230V on hook-up. The size most two-berth conversions settle on.
-
Pundmann 10 litre
from £450A proper shower, or a family on board
Ten litres on twin rods, or the Air Combi that creates hot water from a blown air heater. The most capacity in the range.
Kits, if you would rather order once
The same products, boxed together with the parts they need. Five per cent comes off at the checkout, so a kit works out cheaper than the same items bought one at a time.
SavvyVan3 full kit
from £782
SavvyVan3 with SavvyTanks, SavvyStance and SavvyLights, plus a tank probe, a drain valve and a second temperature probe. Everything matched up and ready to fit, in one order.
SavvyTanks kit
from £179
The SavvyTanks module with one or two probes and a motorised drain valve. The module cannot read a tank until it has a probe, so this is the version that works out of the box.
The whole range, side by side
Everything we make, what each part is for, and how much of an afternoon it is likely to cost you.
Swipe the table sideways for fitting and price.
| Part | What it is for | Fitting | From |
|---|---|---|---|
| SavvyVan3 | The screen, and the brains behind it | Some wiring - An afternoon for most vans | £400 |
| SavvyShunt | Know what your battery is doing | Some wiring - About an hour | £120 |
| SavvyTanks V3 | Tank levels at a glance | Straightforward - An hour or two, most of it running probe cable | £90 |
| SavvyLights | Every light, dimmed and named | Straightforward - An hour, plus however long the lights themselves take | £120 |
| SavvyStance | Level, without the guesswork | Straightforward - Half an hour | £75 |
| SavvyPropex | Your Propex, on the panel | Straightforward - An hour | £125 |
| Autoterm add-on | Your Autoterm, on the panel | Straightforward - An hour | £125 |
Prices are the cheapest option for each part and include VAT. Every add-on needs a SavvyVan3 panel to talk to - they are extensions of it rather than standalone gadgets.
Before you buy a shunt
Some batteries just tell us themselves
If your battery is one of these, the panel reads it directly over wireless - state of charge, current, the lot - and you do not need a shunt at all.
