Battery
WattCycle lithium batteries
Your WattCycle pack cell by cell: voltages and imbalance, temperatures, state of health, cycles and remaining capacity — and every BMS protection becomes an alarm on the deck.
Via Deeck Bridge
The Bluetooth Victron dashboard
The intelligent dashboard for the Victron system without a GX.
Your SmartShunt, MPPT and chargers already broadcast over Bluetooth. Deeck listens and turns them into one live dashboard — on iPhone, CarPlay and Apple Watch. No GX, no cables. And a dashboard you can talk to.

Who it's for
If your Victron devices only talk Bluetooth, Deeck is for you.
A camper, a van or a boat usually runs a SmartShunt, a SmartSolar charger, maybe an Orion or a Blue Smart charger — and no GX device to tie them together. VictronConnect shows them one at a time. Deeck shows the whole system, all the time.
Campervan & RV
House battery, solar, engine charge and mains — one deck on the phone, one on CarPlay while you drive.
Boat
Service and starter batteries, solar and shore power. Glance at the wrist before you cast off.
Off-grid cabin
Autonomy in days, a forecast that watches the sky, and alarms that reach you even far away.
- 1deck, 3 screens
- 9Siri questions today
- 0cables to run
- 7days of solar forecast
iPhone
The whole system, on one deck.
Everything a monitor should tell you, in a screen you actually enjoy looking at. Built for iPhone first, with the care of an Apple-native app.
Autonomy in days and hours
Computed from how your battery is really behaving, counting down to the reserve you choose — not to zero.
Energy and history
Production versus consumption, solar, engine and shore broken out, state-of-charge trend over 24 hours, 7 or 30 days. Persistent history and CSV export.
Solar forecast
Seven days ahead, calibrated on your own panels and habits. It tells you whether this weather keeps you above the reserve — or when you'd dip below.
Alarms and notifications
Low charge, low or high voltage, high temperature, with a heads-up before the critical level. A notification inbox keeps the story.
Live deck
State of charge, voltage, current and the power flowing between solar, engine, mains, battery and loads — updated several times a second, straight from Bluetooth.
Widgets and Siri
Small, medium and large Home Screen widgets with state-of-charge ring, autonomy, sources and the weekly balance. Ask Siri for the battery, the autonomy, the solar production or a full summary.
Dashboard mode
Mount the phone or an iPad on board: always-on display, night dimming, touch lock with PIN.
Backup and transfer
Move to a new iPhone with one AirDrop, set up a second device by scanning a QR code — and with Pro, an automatic iCloud backup that restores itself on a fresh install.
Setup
Three taps. No keys to copy.
Other apps make you copy 32-character encryption keys by hand. Deeck reads them for you, using the same PIN you already use in VictronConnect.
- 1
Find
Open Deeck near your system. Every Victron Smart device around you shows up on the radar.
- 2
Enter the PIN
Tap a device, type its Bluetooth PIN once. Deeck reads the key by itself and closes the connection.
- 3
Done
The deck is live. Keys never leave your iPhone. Move to a new phone with one AirDrop.
CarPlay
Your battery, on the dash.
Deeck is the first Victron dashboard for CarPlay. While you drive, the head unit shows what matters — in the glanceable layout Apple designed for driving.
Deck tab
Up to eight colour-coded tiles: battery, solar, engine charge, mains, loads, autonomy. Red only when something needs you.
Energy tab
Now, today and the forecast, plus the last seven days produced and consumed.
Devices tab
Every device with its live status. Tap one for its key numbers — state of charge, volts, amps, yield, panel voltage.
Siri tab
The questions you can ask while driving, ready to tap: Deeck reads the answer out loud.
Alarms on the head unit
A battery alarm pops up on the car display, the way navigation alerts do.
Always in step
Same numbers as the phone, refreshed at the cadence Apple sets for driving. CarPlay is part of Deeck Pro.
Apple Watch
A glance at the wrist.
A native watchOS app, not a mirror of the phone: three pages, one swipe, the same data as the deck.
Deck page
Colour tiles for battery, solar, engine, loads and autonomy — readable at arm's length.
Energy page
Autonomy as the hero number, today's yield, the last seven days and the forecast.
Devices page
Your devices in a flat list; tap one for a two-column grid of its key numbers.
On the watch face
A complication with the state-of-charge ring in Deeck green — grey when the data is older than 30 minutes, so you never trust a stale number.
Alarms on the wrist
Battery alarms reach the Watch like any iPhone notification — you feel the tap.
Kept in sync
Values arrive from the iPhone over Watch Connectivity, so the Watch shows exactly what the deck shows. Apple Watch is part of Deeck Pro.
Siri
Not just answers. Actions.
Today Deeck answers nine questions. With Apple Intelligence it will learn to act: the climate first, then alarms, deck and reserve — by voice, from the phone, the Watch or the car.

Third-party integrations
Beyond Victron.
The rest of your system deserves a place on the deck too. Deeck integrates the equipment that off-grid people actually install — and shows it like any other device.
Climate
EZA air conditioners
Pair the EZA over Wi‑Fi and control it from the deck: Cool, Heat, Dry, Fan and Auto modes, set temperature, fan speed, Sleep, Health and X‑Fan. Near the camper on the onboard Wi‑Fi, far away through the cloud — and from CarPlay and the Watch too.

Deeck Bridge
Your Bluetooth system, online. No GX.
Deeck Bridge is free software that runs on a small box aboard — a Raspberry Pi, or the Cerbo GX you already have. It listens to your Victron devices over Bluetooth, exactly like the app does, and puts them online. From that moment the deck works from any distance, and the Bridge watches your batteries around the clock.
Bluetooth
Near
Live readings, several times a second. Works with the app closed through widgets and background updates.
VRM
Far
Your system from anywhere, on the same deck. The solar forecast uses your installation's location.
Deeck Bridge
Bridge
Bluetooth-only system? The bridge publishes it to VRM and sends push alerts to the phone in your pocket. Installed from the app, no terminal.
Without Bridge
- The deck works only near the vehicle
- Alarms only while the app is open
- WattCycle and EZA only on the onboard Wi‑Fi
- Nothing to see from home
With Deeck Bridge
- The same deck from home, the office, the beach
- Push alerts 24/7, even with the app closed for days
- EZA climate switched on before you arrive
- WattCycle battery always in view, cell by cell
- Device settings changed from a distance
Camper in winter storage
The battery slowly drains under the cover. You don’t drive there to check: the Bridge tells you when it’s time to charge.
Boat at the mooring
Service and starter batteries checked every 30 seconds. A voltage drop, a charger that stopped — you know before the weekend.
Off-grid cabin
See what the panels produced today, switch the EZA on an hour before you get there, walk into a warm room.
How it works
Your Victron devices broadcast over Bluetooth, as always.
A small box aboard listens to them — like the app does when you are there.
It puts the readings online and checks your batteries every 30 seconds.
Deeck shows you the deck anywhere and alerts you on the phone, even with the app closed.
The keys stay yours: the app hands them to the Bridge on your own Wi‑Fi. We only deliver the notification; your readings never pass through us. The Bridge is free: the remote deck and alerts it enables are part of Deeck Pro.
No GX? The Bridge is the cheaper, simpler way online.
A Cerbo GX costs €300 and more, plus cables to every device. The Bridge costs the price of a Raspberry Pi and touches nothing on your system.
Why the Bridge, not a Cerbo
- About €70 once, instead of €300+ plus wiring
- Your devices stay exactly as they are: nothing to re-pair, nothing to reconfigure
- Everything Pro does — remote deck, push alerts, climate from a distance — with one small box
- Installed from the app, no terminal, no computer
What you need
- A Raspberry Pi with Bluetooth: Pi 4, Pi 3B+ or Zero 2 W
- A microSD card (16 GB or more)
- A 12 V → USB power adapter, or any USB socket aboard
- Internet aboard: a router, a 4G dongle or a phone hotspot
About €60–90, once. The software is free; it activates with Deeck Pro.
Guide: install Venus OS and the Bridge in 20 minutesAlready have a GX? You are two minutes away.
Your system already reaches Victron’s cloud. What it is missing is everything Deeck adds on top — and the devices Venus OS does not read.
Why Deeck, if you have VRM
- CarPlay, Apple Watch, Siri and Apple Intelligence — VRM has none of them
- The Bluetooth-only devices Venus OS ignores show up in Deeck and in VRM
- Push alerts checked every 30 seconds with the app closed, not just VRM emails
- Nothing to buy: two minutes in the Remote Console
What the Bridge adds on your GX
- The Bluetooth-only devices Venus OS ignores (SmartShunt, MPPT, Orion paired only over Bluetooth)
- WattCycle batteries and the climate, also from a distance
- Push alerts to Deeck, not just VRM emails
- Device settings changed from a distance
Nothing to buy. The Bridge installs on the Cerbo GX, Venus GX or Ekrano you already have.

About Deeck
In plain words
- Deeck is an iPhone app that monitors Victron Energy systems over Bluetooth, using the Instant Readout broadcast of Victron Smart devices.
- It is made for systems without a Cerbo GX or other GX device: no wiring or extra hardware is needed for local monitoring.
- It includes a CarPlay app and a native Apple Watch app, Home Screen widgets and Siri shortcuts.
- It adds what VictronConnect does not offer on iPhone: a single dashboard for the whole system, persistent history, autonomy in days and hours, a solar forecast and alarms.
- Remote access works through a Victron VRM account or through Deeck Bridge, a free package for a Raspberry Pi running Venus OS.
- Deeck also integrates WattCycle lithium batteries and EZA air conditioners.
- Deeck is an independent product and is not affiliated with Victron Energy B.V.
- Deeck is free for local monitoring; Deeck Pro (CarPlay, Apple Watch, solar forecast, remote access and Bridge) is a one-time App Store purchase with no subscription.
Questions
Good to know
What is Deeck?
Deeck is an iPhone app that turns your Victron Smart devices into one live dashboard over Bluetooth, with companion apps for CarPlay and Apple Watch. It shows state of charge, power flow, energy history, autonomy and a solar forecast, and warns you with alarms.
Do I need a Cerbo GX or any Victron hardware beyond my devices?
No. Deeck reads the Bluetooth broadcast of your Smart devices directly. A GX device (or Deeck Bridge) is only needed if you want to see your system remotely.
Which Victron devices work with Deeck?
Every device that broadcasts Bluetooth Instant Readout: SmartShunt, BMV-712, SmartSolar MPPT, Orion XS and Orion-Tr Smart, Blue Smart IP22/IP65 chargers, Phoenix Smart inverters, Smart Lithium, Lynx Smart BMS, Multi RS and Inverter RS, Smart BatteryProtect, DC energy meters and VE.Bus systems.
Does Deeck replace VictronConnect?
For watching your system, yes — that's what it's built for. Device configuration and firmware updates stay in VictronConnect. Deeck never keeps a connection open, so VictronConnect and your GX keep working as before.
Is there a CarPlay app for Victron systems?
Yes — Deeck. It shows a glanceable deck of battery, solar, engine charge and loads on the head unit, an energy tab, your devices, Siri questions and battery alarms on the car display.
Is there an Apple Watch app?
Yes. Deeck ships a native watchOS app with three pages — Deck, Energy and Devices — fed by the iPhone, plus battery alarms on the wrist.
Is it safe? Where do my keys go?
Encryption keys are read once and stored in your iPhone's Keychain. They are never sent to us. Backups go to your iCloud, encrypted by Apple.
What is Deeck Bridge?
Free software that runs on a Raspberry Pi or on the GX you already have: it publishes your Bluetooth-only devices to your VRM account, sends push alerts to your phone and lets Deeck reach WattCycle and EZA from a distance. Installed in two minutes, configured from the app. See the Bridge guide.
Is Pro a subscription?
No. Pro is a one-time purchase on the App Store — €39.90, launch price — and stays yours forever, on a new iPhone too: just restore purchases. Free never expires, so you can try Deeck for as long as you like before deciding. And if you change your mind, you can ask Apple for a refund within 14 days of purchase.
Android?
Deeck is built for iPhone first. An Android version is planned.
Is Deeck affiliated with Victron Energy?
No. Deeck is an independent app and is not affiliated with or endorsed by Victron Energy B.V. Victron and VictronConnect are trademarks of their owner.
