What has changed

2.5.1 to 2.5.12

Released October 2026

The SavvyDot. A small round touch screen that brings up to five things from your panel to wherever you want them: a tile, and - where your van has what each one needs - a tank, a light or a scene, the heater, the van’s level or the battery’s charge. A tap switches a tile, steps a light through its brightness, puts a scene on, or switches a tank’s relay or the heater; the level and the battery are there to read. It charges over USB-C, fixed in place or on a charging plate you can lift it off. Your installer sets it up. From 2.5.3, Deploy shows a full-screen SavvyDot Update screen with a progress bar whenever it sends the dot a new layout or a software update, gives the update the panel’s wireless to itself, and has a Cancel while a software update goes over. The SavvyDot guide has the details.

Swipe between screens. Choose a screen for a swipe left, right and down from the home screen - the battery, the tanks, the lights, the heater, levelling, WiFi and more - under Settings → Gestures. Swipe up to come home. Nothing is set until you choose.

Logic rules can do far more. A rule can now start at a time of day, on the days you choose, or when a temperature, a voltage, the battery’s charge, a tank’s level or the gas level crosses a figure, when a SavvyTanks relay or the gas bottle switches, or when the heater is set or starts, stops or reports a fault. It can switch a tile, a SavvyTanks relay, the gas bottle, a SavvyLights light or scene, or the heater, dim every light to a ceiling, sound the buzzer, or put a message on the screen. One rule can have up to eight conditions, joined by and or or, and up to eight actions, and it can wait up to eight hours before acting. A rule that opens the gas acts with nobody watching, so read the gas warnings before you build one. Rules can be edited as well as added, and a rule now follows its tile however it is switched - on the panel, from the phone app, from a SavvyDot or by another rule. Auto Gas Mode and the water heater’s settings now work as rules the panel keeps for itself, which you can see on the Logic Rules page. How logic rules work.

More for logic rules to watch and do (2.5.3). A rule can watch a time range - between 22:00 and 07:00 - which, joined to another condition with and, keeps the rule true for the whole of it; the panel’s screen (idle for a while, or going off or on); the phone connecting or disconnecting; the levelling; the battery’s charging or discharging current; and the heater’s set point. A rule can switch the screen off or on and move the heater’s set point. Tiles are named by the names you gave them, not by number, and times are set in a small clock popup. A temperature condition now goes up to 100°C. The screensaver is now two rules the panel keeps for itself, and Settings → Display & Sound has a new Day Hours row that says when the day screen timeout applies.

Victron SmartSolar chargers. The panel reads a Victron SmartSolar charger over wireless, with no module of ours in between, and shows what it is making on the home screen, under the battery. Pairing a SmartSolar.

Clayton Power LPS2. The panel reads a Clayton Power LPS2 as your battery, charger and inverter in one, and switches its inverter from the battery page. Pairing a Clayton.

Kartt diesel heaters. The panel now runs a Kartt diesel heater over wireless, with no module of ours in between. It has the Heater page, just as an Autoterm does: Fan and Diesel, each with ten levels, Auto heat, and the heater’s own fault messages. Your installer pairs it, and the panel sets the heater model by itself. Like an Autoterm, it needs a temperature sensor set to Inside before it will heat. It is run from the panel - a SavvyDot has no slot for it. The Kartt guide.

The Motor Driver, for trade. A new add-on for converters and installers. It lets the panel open and close one motorised awning, step, bed, pop-top or side pod with a tap, stops early if something is in the way, and can be locked out by a sensor. It is sold to trade only. About the Motor Driver.

Ready for SavvyVan 3.1. 2.5.1 is also the software for our trade-only SavvyVan 3.1, which has a fuse on every circuit. On a 3.1, Fuse Monitor in the side menu lists each fuse as OK or Blown - and if the fuse on a circuit that is switched on blows, the screen wakes and Fuse Monitor opens by itself. About SavvyVan 3.1.

A new battery page, on new panels. A panel set up new on 2.5.1 opens a new battery page from the battery dial: the battery’s charge, with its voltage, current, power and time to empty or to full beside it, Usage Graph and Battery Data buttons, a solar card when a Victron SmartSolar is paired, and - when nothing else sits beside the battery - a graph of its charge over the last 24 hours, 7 days or 28 days. Like the battery’s charge on the home screen, it needs a SavvyShunt or a battery that reports itself. A panel updated from 2.4 kept the Power Management page it already had - until 2.5.12, below.

A new look for the voltage dials. The voltage dials on the home screen are now a battery outline with ten bars, lit red, yellow or green by how full a 12V battery is. The second voltage input, usually wired to the starter battery, reads Vehicle beside its voltage and always sits last, under the battery and solar dials. The low voltage cut-off watches the leisure battery only, never the second input.

Get Help, on the passcode screen. Send log files is now Get Help, with two buttons behind it: Send Logs, which now tells you when we have them, and Remote Support, which - while you are on the phone to us - lets a SavvyVan engineer onto your panel for up to two hours with a six-character code. It needs the panel online, only somebody at the panel can start it, and you can end it whenever you like.

Updates show their progress. Update Now asks before it starts, then shows each stage - connecting, downloading, installing - with a progress bar, and says plainly if something went wrong, with a Retry button. The update to 2.5.1 itself still runs the old way, with the screen blank for part of it.

Steadier WiFi. The panel keeps to the network you choose on Wifi Settings, shares its radio better with your wireless add-ons, and if the WiFi drops it reconnects by itself - no restart needed.

Heating from the phone app. With a Propex or Autoterm add-on and SavvyVan Pro, set the temperature and start the heater from the SavvyVan app. Started that way, it runs for two hours and the van switches it off, even with your phone off - unless you choose Keep running past 2 hours as you start it. The panel says so when it does: Heating switched off after 2 hours, the time limit set from the app.

More choice in the heater schedule. Auto off delay now offers Off, or from half an hour to 8 hours, in place of 5 to 20 minutes. Off keeps the heating on at the set temperature until somebody turns it off. A new panel starts with the schedule off and no days ticked; a schedule you already have is kept as it was.

Diesel heaters need a temperature probe to heat. An Autoterm or a Kartt now needs a temperature sensor set to Inside before it will heat at all - the panel says so instead of heating without one. The fan still runs either way.

Autoterm faults wait for Reset. When an Autoterm diesel heater reports a fault, the panel shows the heater’s own fault number and what to check, and keeps the heater off until somebody presses Reset on that message - whether it is asked to start from the panel, the phone app, a SavvyDot, the schedule or Auto heat, and even after a restart. Switching it off always works. Reset does not start the heater, so switch it on again once the cause is fixed. If the heater stops by itself without reporting a fault, the panel says so and waits for Reset in the same way.

Auto Gas Mode follows the burner. With Enable Auto Gas Mode ticked on a Propex, the panel opens the gas bottle as the burner starts and closes it as the burner stops. A bottle you open or close by hand stays as you left it until the burner next starts or stops - so a bottle you open to cook while the heating is on closes when the burner next stops.

The battery page, on every panel (2.5.12). The Power Management page has been retired: every panel now opens the battery page new panels have had since 2.5.1 - the charge on a dial, voltage, current, power and the time left beside it, Usage Graph and Battery Data. Nothing to do; tap the battery dial as before. A Teconnex battery keeps its own page.

An on/off switch for the heater schedule (2.5.12). Heater Schedule has an Enabled box, top right. Untick it and the schedule stops, keeping its days and time for when you want them again; heating the schedule had already put on goes off as you leave the page, and heating you switched on yourself is left alone. After the update the box is ticked if any day was, so a schedule you already have keeps running until you untick it.

A clearer weather strip (2.5.12). New weather icons, each day’s real high and low, and always today and the next five days, headed by the day and date. A day the forecast no longer reaches reads No Data. The forecast is fetched once a day and kept as you move around the panel.

Pairing the phone app starts with Enable App Features (2.5.12). A panel that has never had the app switched on has no pairing code yet: App Information and App Settings say Turn on app features to pair your phone. Tick Enable App Features in App Information and the code appears. A panel that already had app features on keeps its code, and its phones stay paired. A small number of panels make themselves a new pairing code with this update - if yours now says No phone paired, scan the code again from the SavvyVan app.

Safer updates (2.5.12). An update is now put together beside the software it replaces, and only takes over once every file is checked. If it cannot finish - or the panel has no room for the second copy - the panel stays on the software it had and says Update could not be installed. Please retry or contact SavvyVan Support.

Fixes and improvements

• Heating: smoother schedules, steadier Autoterm starts, heater dial arrows that answer straight away, and the heater’s logo on its messages.
• Battery: clearer readings and time left, on the battery dial and the battery page.
• Water heater: runs for its Auto off delay however it is switched on - on the panel, from the phone app, from a SavvyDot or by a rule.
• Wireless add-ons: steadier connections, a module that drops out is tried again within a minute, one module no longer holds up the others, and a steadier online and offline status.
• Tanks: the home screen’s tank shows OFL when its module is offline.
• Remote Support: a smoother start to a session.
• SavvyDot: a software update that is cancelled or interrupted leaves the dot on its current software (dot firmware 1.8.4).
• Tiles: every Advanced Options choice saves first time, and custom tiles carry across from older software.
• Phone app: until a phone is paired, App Settings asks for WiFi before it shows the pairing code.
• Settings: a new back arrow on every settings page.
• Refinements to the Lights page, levelling and Roamer batteries.
• Logic rules: a long Type list scrolls, with up and down arrows at its right (2.5.12).
• Levelling: shows Offline until it has a complete reading, and the wheel-distance box shows its m (2.5.12).
• Battery: a SavvyShunt’s settings appear on Battery Management as soon as it is paired (2.5.12).
• Support and the phone app: Send Logs, Remote Support and app pairing are more dependable, and the panel restarts its own support service if it needs to (2.5.12).
• WiFi and wireless add-ons: the panel recovers by itself on a weak WiFi connection (2.5.12).
• Gas bottle: steadier control through a SavvyTanks module (2.5.12).
• SavvyDot: steadier software updates (2.5.12).

2.4.5

Released October 2026

Autoterm diesel heaters follow the set temperature on every level. Picking a level from 1 to 10 now heats while the van is below the set temperature and rests once it is warm, rather than heating regardless. The flame stays lit on the main screen while it rests. Without a temperature sensor set to Inside, a level still runs at full intensity as it always has.

The gas bottle stays as you left it with a Propex. Unless Enable Auto Gas Mode is ticked, the panel never opens the gas bottle - and now it does not close it behind you either: switching the heating off, or a schedule ending, leaves the bottle as it was. A scheduled gas start does not run if the bottle is closed or the heater is not connected, and the panel says why.

Fixes and improvements

• Heating: steadier Autoterm levels, and heater messages that fit the screen and read in full.
• Pairing: phone stays connected reliably.
• Settings: saved immediately when you make them, safely even if the power goes off.
• Tanks: Source option cleared when a gas tank is turned off.
• Wireless: panel uses memory more efficiently over long spells.

2.4.4

Released September 2026

Autoterm Air 4D heaters are now supported. The panel detects whether it is connected to an Air 2D or an Air 4D automatically - no setting needed.

Smarter reconnecting for wireless modules. When a paired module stops responding - because it has been unplugged, taken out of range, or switched off - the panel now waits progressively longer between reconnect attempts, leaving the rest of your modules to get on with it. After three missed attempts it waits 30 seconds, then a minute, then two, then four, and after that checks roughly once every five minutes. The moment the panel hears the module advertising again it reconnects straight away.

The pairing list fills live. On the pairing page in Installer Settings (the one with Scan on the right), the list of devices the panel can see now fills in as modules come within range - without needing to tap Scan.

Quicker battery history on the SavvyShunt. History now displays faster, and what you already have carries across automatically on the first start after updating. The day view shows a rolling 24 hours rather than the calendar day.

Fixes and improvements

• Wireless modules reconnect more smoothly after a weak signal or an adapter reset.
• The battery history button reads Reset History on every battery view.
• Improvements for Autoterm heaters on 24V systems.

2.4.0

Released September 2026

Electric-only Propex heaters are now supported. If your van has a Propex heater running on electricity rather than gas, you can now choose Propex (electric only) in Heater Settings and control it from the panel.

Batteries with a PIN are now unlocked directly on the panel. If your Sky Energi, Titan or Fogstar battery is locked with a passcode, the panel asks for it the first time you pair the battery and remembers it afterwards. You no longer need to remove the password from the battery before pairing.

Smoother WiFi on mesh networks. Moving between access points on a multi-router site now hands over in under a second, keeping the panel’s network address as it goes.

Fixes and improvements

• Lighting presets save straight away and keep their values when you adjust a light afterwards.
• Smoother redrawing of the main screen after a wireless device is removed.
• The SavvyShunt reconnects in the same gentle way as every other wireless device.

2.3.14 and 2.3.15

Released July 2026

Starlink integration. The panel now talks to a connected Starlink router, with a page showing signal status and data usage - so you can keep an eye on your internet without leaving the unit.

Update from the notification. When an update is available, the notification now carries an Update Now button. No digging through settings.

Better remote support. More useful information reaches us when you report a problem, so we can pinpoint issues faster and confirm when a fix has already gone out.

A page for the mobile app. Reachable from a link in the top bar, which changes colour so you can see the state at a glance - grey for offline, orange for connected, green when your phone is paired. The pairing QR code lives permanently on this page, and you can reset the pairing or switch the phone connection off entirely if you would rather save the power. The app is still in testing, so this page is only there for people on the beta programme.

Notifications have moved into the settings menu on the top left, which gives the top right of the screen a bit more room.

Faster online/offline status, so what is on screen matches reality sooner.
