MultiBMS

MultiBMS 1.0.6 makes the Apple Watch companion fully live and dependable. Watch screens now use the currently selected battery or group, reject stale telemetry, and stay consistent with the iPhone. Use Battery Monitor mode without a ride profile, or configure activity profiles for GPS speed and top speed, distance and efficiency, G-force, laps, BMS temperature, cell health, and alerts. This release also refreshes every Watch screen, improves Bluetooth recovery and switching between saved BMS devices, expands protocol support, and fixes startup stability.

A completely upgraded Apple Watch experience is here. Record rides directly from every Watch screen while viewing live voltage, current, power, state of charge, GPS speed, G-force, temperature, and elevation. New live curves synchronize current, speed, and G-force, while the session screen tracks top speed and peak G. On iPhone, choose which channels to record, review saved sessions, compare electrical and ride data on smooth multi-line graphs, and scrub through the complete timeline. This update also improves pack-detail layouts, group icons, multi-pack cell identity, stability, and App Store compatibility.

Apple Watch is now live. Choose Ride Profiles, batteries, Watch pages, BMS-temperature and voltage alerts, and Race/Ride metrics, then view live telemetry relayed securely from your paired iPhone. Race and Ride sessions now include detailed session and per-lap voltage drop, lowest voltage, peak current and power, temperature, weakest-cell, cell delta, and energy metrics. This update also adds reusable profiles for e-bikes, scooters, ATVs, karts, boats, and custom builds; current-responsive charging and discharging visuals; a clearer Watch setup path in Settings; expanded BMS protocol support; and improved ANT compatibility. MultiBMS is built by a hobbyist for hobbyists. Bug reports and feature requests are always welcome at [email protected].

A completely redesigned dashboard makes groups, packs, and every cell easier to read. New charging and discharging effects show live direction, current, and power, with animation speed that responds to amperage. Create parallel or series battery groups and see combined voltage, current, power, capacity, cell health, and individual pack detail in one place. Rated-capacity controls, multi-pack connections, reconnection, alerts, support tools, and first-launch guidance have also been improved. This update introduces an Apple Watch companion preview with Fleet, Cells, alerts, and Race Mode screens. Builders and racing enthusiasts can explore laps, voltage drop, peak current and power, temperature, weakest-cell, energy, and session summaries. Watch telemetry is clearly labeled demo data in this release; live Watch synchronization is coming next. MultiBMS is actively developed.
