Firmware updates from TITAN support. When TITAN support prepares a firmware update for your battery's BMS, it appears under Settings, My Batteries, and runs from your iPhone beside the battery. If it is interrupted, TITAN stops safely and tells you what to do next.

Your battery on the dashboard. Charge, time remaining and any alert now show on your car's screen through CarPlay on iOS 26, and on your lock screen and in the Dynamic Island. The steps are under Settings, Alerts and notifications. The warning that your battery's readings had stopped changing could fire when you had simply walked out of Bluetooth range. Time out of range no longer counts, TITAN waits an hour to be sure, and the same alert no longer arrives twice. Some batteries that can hibernate were shown as unable to. TITAN now checks again before it says so, and shows that it is checking in the meantime. You can now teach TITAN an appliance: switch one thing on and off while TITAN measures it, and it learns that appliance's real draw. Find it under Settings, TITAN AI, or tap Teach it instead when correcting a detection. A declared diesel heater is now recognised while it runs. A battery with a Bluetooth extender fitted now shows as one battery, not two in parallel. Victron Orion-Tr Smart DC-DC chargers now show their readings instead of waiting, and Orion XS is supported with current and power. The current dial reads sensibly on large banks, long battery IDs show in full, correcting an appliance from the energy flow no longer leaves a blank screen, and TITAN AI's advice on fuses, parallel banks and charge voltage now matches TITAN's published figures.

This update fixes the Monitor header reading Standby while charging or discharging, a crash when the guided tour or the notifications list closes, and a background Bluetooth disconnect that could stall. TITAN AI is now a second dashboard. The page opens on what matters: anything worth a look, your energy today, your reserve in days and what is running right now, with the detail underneath. Its confidence score now measures how well TITAN knows your own setup, so it rises sooner. TITAN shows appliances while they run and is better at telling a kettle from a fridge. Add yours from the TITAN AI page, and on a boat you can declare a windlass, bow thruster, winch, bilge pump, macerator or watermaker for it to look for, at 12 V or 24 V. Chargers, inverters and battery monitors now show their key figures together on one page under the energy flow, with tanks and sensors alongside, and a tap opens the full detail. A monthly summary of the energy you used and took in, with your solar share and lowest charge, arrives on the first of each month once you turn it on under Settings, Alerts and notifications. Settings is grouped into a handful of menus with the four most used at the top, and the guided tour matches. Five new vehicles for the energy flow: panel van conversion, 4x4 overlander, horsebox, narrowboat and sailing yacht. Clouds and rain on the energy flow are redrawn. You can now delete your account in the app under Settings, Account, Delete account. Live readings keep moving while the battery's event log syncs.

Fixes a crash that could occur when the guided tips appeared over the Energy Flow. TITAN AI is also better at telling solar, mains and engine charging apart, learned from what owners across the fleet have told it.

Set it up your way. Alerts you define. Tell TITAN to warn you when voltage, charge level, temperature or discharge current crosses a limit you choose, and it keeps watching while the app is in the background. Set them under Notifications. Arrange the Energy Flow. Tap Arrange, or hold a node, and move the map around your own setup. It stays where you put it, in full screen too. History by the week, month or season, with the highs and lows around the average and a summary of where your battery spent its time. Make it yours. A short one-time step to set appearance, your vehicle, landscape, text size and how power is shown. Skip it if you like; it is all in Settings. Landscape and full screen. For tablets and built-in screens. Turn on rotation and the dials sit beside your readings. Upright by default. A sharper engineer. TITAN AI runs on a far more capable model and can see the chargers, tanks and sensors you have connected. Report a problem in two taps, with your battery id attached so we can look and your email so we can reply. The solar warning is corrected: it now works from your panel size and the sunshine that day rather than your own past average. The weather badge on the energy flow follows the real forecast. Faster startup, smoother scrolling and dials, Android stability fixes.

Your battery stays connected. If the Bluetooth link drops, TITAN now keeps trying until it has your battery back, and tells you it is working on it. Previously a single failed attempt was enough for it to give up and wait for you to reconnect by hand. Also in this update: • The Data view no longer opens blank, and no longer goes blank if a battery drops out. It always tells you what it is doing and fills in the moment your readings arrive. • Whichever colour scheme you pick is now the one you get every time. Diamond in particular used to last only until you closed the app. • Light mode looks right on every screen. Connecting screens were drawing a dark panel over the light theme. • A battery left sitting undisturbed is no longer reported as having stopped responding. That warning now takes far more evidence before it says anything. • The charge percentage warning clears properly once a charge has finished, and the advice behind it has been corrected: let a charge complete rather than unplugging the moment it reads 100%. Nearly all of this came from customers writing in. Keep it coming.

Every alert kept, every battery connected. Notification History: tap the bell on the TITAN tab to read back everything TITAN has told you, in the original wording, with the time it happened. Anything you have not seen is marked new. Steadier bank connections: if you run more than one battery, they now connect one at a time instead of competing for the Bluetooth radio, and a battery that does not answer straight away gets a second attempt rather than being reported out of range. Faster first readings: your dials fill in as soon as the battery answers. Fewer repeat alerts: a fault you have already been told about stays quiet. Your monthly summary now reports what your batteries actually delivered over the month, in amp hours and kilowatt hours, with your closing charge and health. Turn it on in Settings, under Notifications. Live Stats now counts every battery you own, not just the one you are connected to, and keeps working when you are away from the van. The app now has multiple EU languages - go to Settings > select language TITAN AI answers in German, French, Spanish, Italian and Dutch, including when you are offline.

Wind turbines now sit alongside solar in TITAN. Declare your turbine and the app forecasts wind speed, estimates your daily yield and shows it turning on the Energy Flow map. Also in this update: • New appliances: blenders, oil-filled radiators, panel heaters and water distillers • Heaters with low, medium and high settings: TITAN learns your real wattage • Guides from titanlithium.co.uk now appear where they are relevant • A clearer, kinder experience if your battery ever runs critically flat • Fewer false alarms: a normal day of use is no longer mistaken for an overnight drain

More brands, one map. Connected Devices now supports Renogy, Thornwave, Gobius, Safiery, EcoFlow and Simarine alongside Victron, Mopeka and Ruuvi. Run two or more solar chargers and TITAN sums their output with per-charger detail. Also: steadier reconnecting on iOS, and stability fixes.

A big one. TITAN now sees your whole rig, not just the battery. Connected Devices: add Victron, Mopeka and Ruuvi Bluetooth sensors Energy Flow Monitor: a live view of power moving around your setup Measured charging: real solar and engine readings, no more guessing TITAN AI can now name your always-on gear like routers and Starlink Hot weather warnings alongside the existing cold ones Tidier settings, a keep-screen-awake option, and accuracy fixes throughout Open the app for the full tour.

A few fixes for 2.2.0: * Knows your appliances: tell TITAN which appliances you run and it now watches for each one and tracks how much power it uses. * Sharper charge detection: better at telling solar, mains and engine charging apart, especially in the first few days after setup. * Steadier live readings: fixed a rare issue where live data could stop updating during a very long session.

This update makes TITAN AI smarter the more you use it and adds a fun new way to see your impact. * Rate the AI: tap thumbs up or down on any insight or detected appliance. Your feedback teaches TITAN to read your system more accurately. * Quick charge check: When TITAN is unsure whether you are charging from solar, mains, or the engine, it may ask. One tap helps it learn. * Count your appliances: set how many of each appliance you run, such as two fridges or three lights. * All feedback is anonymous and can be turned off at any time in Settings under Help Improve TITAN AI. * Live Stats: a new tab on the TITAN page showing what the whole fleet has delivered - energy, capacity and today's running total - alongside your own contribution, and a playful "homes powered" view that grows as the fleet does. * Release history: browse the What's New for every TITAN update anytime in Settings. Thanks for helping us build the most accurate battery AI on the water, the road and off-grid.

* New: battery banks. Keep batteries on separate circuits (for example domestic plus engine) in their own banks and monitor all of them at once, each with its own wiring mode. * New: light theme. Switch between the classic dark look and a new light look in Settings. * New: home and lock screen widget with charge, status, voltage, current and runtime at a glance. * New: ask Siri about your battery. Charge level, runtime forecast and "will I make the night", even when the app is closed. * The AI Engineer can now answer offline on supported iPhones using on-device intelligence. * History graph now draws a line on days with sparse data. * Light theme fixes throughout, and the keyboard now tucks away when you scroll the AI chat.

* Smarter AI usage estimate: now shows your typical daily use and a heavy-use day, with a clearer "how long your charge will last" range that references your current charge. * Better solar detection - solar charging is now credited even before the weather data loads for users with panels. * More accurate AI appliance detection and fewer low-value notifications. * Choose a fixed scale for the current/power dial, or keep Auto - now with a steadier needle that won't jump when the load changes. * AI appliance detection: you can now remove a wrongly-detected device, not just rename it. * Protections: see fault counts "since reset" alongside the battery's lifetime totals, with a per-trip reset that never alters the BMS log. * The AI confidence breakdown now has a clear close button. * Fixed a battery-life estimate that could read too low on packs with prior use.

Improved daily solar yield accuracy - your "Average Daily Solar Yield" tile in the AI tab now reflects only the readings the app has actually observed from your live solar sessions, not approximations based on whatever weather the app happened to see at launch time. Resolved a rare issue where a battery serial could appear "already claimed" when ownership had legitimately changed. Customers affected by this no longer need to contact support - just open the app and the claim will complete automatically. Stability and reliability improvements.

TITAN AI just got smarter - again. The big one this time is solar accuracy. • The AI now learns your panel's real output over time and separates solar input from real battery consumption, so daily Ah totals reflect what your battery is actually doing • Weather data now blends UV with cloud cover for more honest solar yield predictions • Daily usage estimates rebuilt from the ground up - four layers of cross-checks (live current, BMS log replay, offline gap-fill, SOC reconciliation) eliminate the inflated readings some users saw • Smarter context across the board - the AI now considers temperature, weather, voltage and history together before flagging anything, so you get fewer false alerts and more useful insights • New AI Confidence meter shows how much to trust today's stats • Tiny standby loads (USB hubs, alarm panels, thermostats) are now counted properly • Release notes always available in Settings if you want to see this again

Refinements to the on-device AI: • Fixed a drift calculation bug on 36V banks. Previously the AI could show ~50% phantom drift on a healthy 36V pack at the top of charge. • Recurring-protection alerts (e.g. "Discharge MOS Fault triggered N times last week") now age out properly once the underlying issue is resolved — no more lingering alerts on packs that have already been fixed. Plus reliability + security improvements to the cloud sync path.

TITAN AI now tells you how much to trust its numbers. • New "AI Confidence" meter at the top of the TITAN AI tab. A single composite score (Calibrating / Learning / Confident / Highly confident) that answers the question "should I trust the AI's numbers right now?". Replaces the old "Days / Sessions tracked" stat tiles • Tap the meter for a full breakdown of what feeds the score — telemetry depth, charge/discharge cycles, SOC range observed, NILM appliance learning, your declared appliance list, and BMS reading stability. Each row shows where it is, what its target is, and what you can do to raise it. • The meter is self-correcting — no "reset" button needed. As the AI gets a better picture of how you actually use the battery, the score climbs; if your BMS starts showing calibration drift, the score honestly drops to flag it. If you've never connected the app to a battery before, you'll land in "Calibrating" and the meter will walk up over the first week of normal use. Stability: • Fixed three crashes reported via Crashlytics — one on first launch after the OS restored the app (Android Google Sign-In back-stack), one when the Bluetooth permissions dialog was open through a navigation change (iOS), and one rare null inside the framework's text-field long-press handler. The first two are eliminated; the third is now logged as diagnostic data instead of crashing the session. • Fixed the monitor dashboard going blank for several seconds while the periodic BMS event-log sync was running. The signal-loss watchdog was wrongly counting the deliberate poll pause as a dead BLE link and tearing the session down; it now respects the pause and the dials stay live throughout the sync. Keep the feedback coming to info@titanlithium.co.uk.

TITAN AI just got smarter. Tell it what you run from your battery and it learns your setup straight away — no more waiting on it to guess. • Brand-new appliance library in the AI setup quiz: a full-screen picker with 11 category tabs (refrigeration, cooking, climate, water, lighting, electronics, tools, caravan mobility, marine, home/ESS) covering ~70 items — matching the appliance list on our public Battery Size Calculator. Tick everything you regularly run from the battery and TITAN AI uses the list to identify discharge patterns more accurately and learn how much energy each device uses per day. You can edit the list anytime from TITAN AI → "Your appliances" without rerunning the whole quiz. • Context-aware consumption alerts. If an appliance is using more than usual, TITAN AI now cross-checks the day's weather before flagging anything — so a fridge running harder on a 28°C day reads as "likely due to warmer weather" rather than "something's wrong". No obvious weather reason and the tile leans towards "worth a quick check" instead. Thresholds calibrate themselves to your own patterns over the first few days of use, so you won't see noise from day one. • Solar UV forecast now uses the standard WHO bands (Low / Moderate / High / Very High / Extreme) instead of a single Low/High cutoff — matches what Apple Weather is showing for the same location. • Weather and UV refresh automatically when you bring the app back to the foreground and every 30 minutes after that, so a long-running session can't sit on a stale morning reading. • "Smoother sign-in" — if the cloud profile linked to your account is missing fields (e.g. your name or email), the app now repairs it automatically the next time you sign in. Fixes a small number of reports where Settings showed blank account details and the battery- claim button got stuck on "Could not fetch status". • Discharge activity across the app (monitor dial pips and needle, cell-data row, Connect tile, history list, time-remaining stat) now paints soft amber instead of red so a perfectly healthy battery feeding a load no longer looks alarming. Red is still reserved for genuine faults — including when current is within 15% of the BMS hardware limit, when the dial deliberately flushes red to telegraph "nearing the limit". • Prototype starter (BLS) batteries are now excluded from the AI engine — their intentional overcharge profile is very different from leisure cells and was generating false "charger may need checking" insights. Tap "Open AI Setup" on the new What's New screen, or jump in any time from the TITAN AI tab → "Update setup" tile. Thank you for the great feedback — keep it coming. If anything looks off, contact info@titanlithium.co.uk and include the BMS ID shown in Settings → About.

Quality-of-life update with stability and accuracy fixes. • Adds support for the 36V (12-cell) TITAN battery so the voltage dial displays the correct range instead of flagging red. • Hibernation settings (sleep voltage and delay) are saved more reliably and no longer show a false "did not save" error on older BMS firmware. • Sign-in prompt no longer briefly appears on a fresh launch for customers who are already signed in. • Cloud battery records now always use the original factory ID even when a custom Bluetooth name has been written to the unit — keeps the same battery linked to the same record over its lifetime. • Connect tab cleanup — internal demo unit is now hidden by default and only shown when explicitly enabled. • Minor BLE protection-flag wording and force-update screen links fine-tuned. Thank you for the great feedback — keep it coming. If anything looks off, contact info@titanlithium.co.uk and include the BMS ID shown in Settings → About.

This update improves Bluetooth reliability, battery diagnostics and TITAN AI insights. • More reliable hibernation setting saves, with extra verification after writing to the BMS. • Improved Bluetooth reconnect handling. • Corrected BMS protection/fault labels for more accurate alerts and AI insights. • Refined AI guidance for solar/off-grid users and charging behaviour. • Added AI QA telemetry groundwork to help us improve future insights. • General crash fixes and stability improvements.

Version 2.0.8 improves sign-in reliability, Bluetooth reconnect behaviour, and TITAN AI accuracy. What’s new: • Improved magic-link sign-in flow, including a clearer manual sign-in fallback when email apps block or pre-open links. • More reliable BMS parameter unlock handling, especially around older firmware and recent history syncs. • Smoother Bluetooth recovery after brief signal drops, reducing unnecessary reconnect screens. • Improved AI usage learning, including solar inference and peak-discharge accuracy. • Small onboarding improvements for users who have not yet signed in or claimed their battery.

Reliability + diagnostics polish • Static-next-to-battery dropouts greatly reduced. The BLE link now self-heals from brief radio glitches without bouncing you to the Reconnecting screen, with extra patience tuned for the 260 Ah metal-cased units. • Parameter-unlock fix. If you were getting "Authentication failed" when trying to set BMS limits on a battery you'd previously written to with the old TITAN app, that path is fixed. • AI advice for parallel banks now uses the correct per-cell voltage reference. No more confusing "set OVP to 14V" recommendations. • Quieter recovery. A one-off signal blip no longer triggers the full reconnect overlay or the "Reconnect failed" snackbar — only persistent drops do, so the dashboard stays put when your battery is right next to you. Behind the scenes we've also laid the groundwork for service-managed firmware updates, planned for a later release. Nothing user-facing yet. Thanks for the steady stream of feedback — keep it coming via Settings → Send feedback or info@titanlithium.co.uk.

This update is a polish pass on top of 2.0.4. Highlights: • Multi-battery registration. Customers with 2+ batteries connected at once can now claim each one with a single tap from Settings → Registration. Previously you had to disconnect and reconnect each battery individually. • Cleaner data for hibernating batteries. When a unit is fully hibernated (typically a 260 Ah with the case button off), the app now recognises the "BLE alive but BMS asleep" state and stops feeding empty readings into your battery's history and the AI insights engine. Real flat- battery data is still recorded as normal — only the deep-sleep frames are filtered. • Sign-in reliability. If a magic link expires, has already been used, or your phone briefly drops connection while tapping it, the app now shows a clear message explaining what to do instead of silently failing. • Stability. Fixed a rare crash that could occur when reconnecting to a battery that had only just powered on, and removed an obsolete iOS background-task entry that occasionally caused crashes on iOS 17+. Bug fixes and reliability improvements: • Fixed an issue where live data could briefly drop and reconnect while viewing the AI page, even within range of the battery. • Faster startup on slow or unstable networks — the splash screen no longer waits on sign-in services that can't be reached. • Stability fix for a rare crash on the Connect screen when backing out of pairing mid-handshake.
