Changelog
What's new, improved, and fixed — in plain language, newest first.
v16
Flash firmware from your dashboard
A Flash Firmware button now appears right in your gateway list and dashboard, so setting up an additional gateway no longer means digging through the command palette.
Simpler website navigation
The header now shows just the essentials — Features, Pricing, Compatibility, and Flash — with How It Works, the mobile app download, docs, changelog, support, and legal links organized into clear sections in the footer.
Compatibility info in one place
Battery (BMS) compatibility and gateway hardware compatibility now live on a single Compatibility page with tabs, instead of two separate pages.
Tabbed account settings
Account settings are now organized into Profile & Security, Licenses, Preferences, and Data & Privacy tabs instead of one long scrolling page.
Friendlier error messages
Failed sign-ins, lost connections, and other errors on the website and mobile app now show plain, helpful text instead of raw technical details.
Manual telemetry upload interval setting
The telemetry upload interval option in gateway settings (website and mobile) has been removed — your Cloud Service plan now sets this automatically.
Gateway charts show correct colors
Gateway detail charts no longer show normal readings in warning or critical alert colors — chart colors are now consistent and reserved for real alerts.
v15
Clearer wording on the free Cloud Service tier
Pricing and terms now describe the free tier as always available, rather than locked to one fixed update interval forever — the interval may still be adjusted over time to stay sustainable, but the free tier itself isn’t going away.
v14
Bluetooth connection history on the mobile dashboard
See your gateway's recent Bluetooth connections directly from the mobile app's dashboard, the same history already shown on the website.
Gateway settings save section by section
Gateway Name, Telemetry, Display, BMS Hardware, Advanced Controls, and Alert Thresholds now each save independently, instead of one long form with a single save button at the bottom.
Mobile dashboard stays live
Battery data on the mobile app's dashboard now keeps refreshing automatically, including right when you return to the app, instead of going stale after it's been open a while.
Low Power Deep-Sleep Mode toggle restored
The Low Power Deep-Sleep Mode switch in Advanced gateway settings is now reachable from the mobile app.
v13
More alert types
Set thresholds for minimum temperature, maximum current, and cell voltage delta (imbalance between cells), alongside the alert types you already had, from your gateway’s Alerts settings.
Automatic sign-out after inactivity on mobile
The mobile app now signs you out automatically after 15 minutes of inactivity, so your battery data stays protected if your phone is lost or borrowed.
Animated cell voltage bars
Cell voltage bars now animate to show charging and discharging in real time, plus a new time-window selector on the status page’s uptime history.
Short, non-sensitive gateway IDs on mobile
The mobile app's gateway list and settings screens now show a short GW-XXXXXXXX code instead of the full internal device identifier, matching the website and dashboard.
In-app links stay in the app
Privacy Policy, Terms of Service, and Support links in the mobile app now open in a built-in browser view instead of switching away to a separate app.
Legal pages updated
Terms of Service and Privacy Policy expanded with clearer detail on liability, read-only device access, and how the project is currently run.
Sign in with Google, fixed on mobile
Signing in with Google from the mobile app now completes properly and takes you straight to your dashboard, instead of opening a browser tab with no way back into the app.
Licenses now auto-attach
A purchased license that wasn't yet linked to a gateway now attaches automatically the next time your gateway checks in.
v12
More gateway hardware controls
Control your gateway's status LED, local web server, relay pin, and sleep mode directly from gateway settings.
Live trial countdown
See exactly how much time is left on your gateway's trial, right from its settings page.
Mobile app download page
A dedicated page for downloading the Android app directly, with Google Play and App Store badges for when those releases arrive.
A dedicated Licenses page
See and manage all your gateway licenses from one place, alongside a redesigned fleet overview.
Per-device licenses and the Licenses page
The per-device license model and its Licenses page have been removed. Cloud Service is now a single subscription for your account, and gateways you have claimed stay claimed. The earlier entry above is kept as the historical record of when the page shipped.
Checkout without leaving the page
Paying for a license or Cloud Service subscription now happens in an embedded checkout instead of redirecting away from the site.
Redesigned gateway settings layout
Wider layout, clearer tab icons, and less cramped spacing throughout gateway settings.
v11
Blog
Follow project updates and deep dives on the new blog.
Individual cell voltages on the mobile dashboard
See each cell's voltage directly from the main dashboard in the mobile app, not just the website.
Transfer your license to a replacement gateway
If your ESP32 hardware ever fails, your existing license can now be rebound to a replacement device at no extra cost.
Customizable dashboard panels
Choose which panels appear on your gateway’s dashboard and in what order.
Redesigned firmware flashing tool
A new flashing tool with a live serial console, one-click restart, automatic firmware selection for your detected ESP32 chip, and the option to set up WiFi over the same USB cable during flashing.
New gateways get a friendly default name
Instead of a raw device ID, freshly claimed gateways now start with a friendly default name you can change anytime.
Direct firmware binary downloads
Superseded by the in-browser flasher — flashing no longer requires downloading a .bin file by hand.
Long gateway names no longer overflow
Long gateway names and IDs are now truncated instead of spilling outside their card.
v10
Much more of the site in your language
The onboarding flow, account settings, alerts, dashboard, device settings tabs, About, and FAQ pages are now fully translated, alongside license and Cloud Service banners.
Gateway sharing form glitch
The sharing form on a gateway's settings page no longer appears nested inside the wrong section.
v9
Removed third-party BMS support claims
The Daly, JBD, and Seplos support announced in this release has been withdrawn. JKBMSR is a JK-BMS project: JK-BMS is the only brand we support, and we no longer claim compatibility with other vendors’ battery packs.
v8
Share a gateway with other people
Gateway owners can now give up to 10 other accounts view-only access to a gateway's dashboard from the new Sharing tab in gateway settings, and revoke access at any time.
Choose how your gateway’s page looks
Pick from five different layouts for viewing your battery’s live data, including a couple of dense, all-dark “technical readout” styles, from a new Templates option in your gateway’s settings.
A public system status page
See at a glance whether everything is running normally, with an uptime history for the last 90 days.
Forgot your password?
You can now sign in with a one-time emailed code if you've forgotten your password, and set a new one once you're in.
Show or hide your password
Every password field across the site, app, and admin tools now has an eye icon so you can check what you typed.
Account settings page
Change your password or email address, and see whether your Google sign-in is linked, all from one place.
Bluetooth connection history now updates live
New entries animate in automatically as your gateway reconnects, instead of only updating when you refresh the page.
Cell voltages moved higher up the page
The Cell Voltages panel moved near the top of your gateway’s page so it’s easier to find.
Sign-in and account pages match the rest of the site
These pages previously looked like a separate, unbranded page — they now share the same look as everywhere else.
Friendlier “page not found” screen
A helpful page with links back into the site, instead of a blank error page.
We now say “Gateway” instead of “Device”
Clearer wording throughout the site, app, and admin tools about what the physical hardware actually is.
Admin tools got faster and more capable
Gateway and account lists are now searchable and paginated, and support staff can remove a gateway on your behalf if needed.
OTA update history table
Removed from the gateway detail page to reduce clutter.
Revoke confirmation now sticks
Revoking a device's access previously showed a confirmation that reset itself if you refreshed the page, making it look like nothing happened. It now shows correctly.
v7
Scan a QR code to add a gateway
Instead of typing in a gateway ID and claim code by hand, you can now scan a QR code shown after setup, on both the website and the mobile app.
Battery alerts with push notifications
Get an alert (and a phone notification, if you have the app) when a cell voltage, temperature, or charge level crosses a threshold you can configure.
Tabbed gateway settings
Gateway settings are now organized into tabs (General, WiFi, Firmware, JK-BMS, Alerts) instead of one long page, so alert settings in particular are much easier to find.
A real app icon
The mobile app now has its own icon, replacing the generic placeholder.
One consistent look across the whole product
Firmware release pages, the website, and the dashboard now share one visual design.
Website and dashboard, one address
The public website and the customer dashboard now live under one address instead of two separate ones.
Mobile app core screens finished
Claiming a gateway, viewing alerts, and checking firmware updates, with clearer status indicators throughout.
v6
Bluetooth connection details on your dashboard
View your JK-BMS's Bluetooth connection details and history right from your gateway's dashboard.
Rename your gateway
Give your gateway a friendly name from the settings page.
Manage WiFi remotely
Change your gateway's WiFi network without needing physical access to the device.
On-demand firmware update checks
Request a firmware update check any time instead of waiting for the automatic schedule.
Faster firmware release pages
Release lists now load progressively instead of all at once, so pages with many releases feel faster.
v5
Light mode
The site, dashboard, and admin tools now default to a clean light appearance, with a toggle for dark mode.
Visual refresh across the whole product
A full visual refresh across the website, dashboard, admin console, and mobile app for better readability and consistency.
Readability improvements
Several color-contrast issues that made some text hard to read were corrected sitewide.
v4
Full JK-BMS lineup support
Full support for the complete JK-BMS product lineup, over both a direct wired connection and Bluetooth.
Delete an offline gateway
Permanently remove an offline gateway from your account (only while it's offline, to avoid accidentally deleting one that's still in use).
Mobile app launch
Initial screens for viewing your gateways, battery data, and account.
Simpler sign-in page
Cleaned up wording and simplified the sign-in experience.
v3
Guided setup wizard
Flash your gateway, connect it to WiFi, and claim it to your account in one guided flow with live status checks along the way — it remembers where you left off if you sign in partway through.
Sign in with Google
Available on both the website and the mobile app.
Wireless WiFi setup
Set up your gateway's WiFi over a simple wireless connection — no cables required.
Firmware update protection
Automatic protection against installing an older, potentially insecure firmware version by mistake.

v2
Free 30-day trial per gateway
Then a single one-time payment to keep it active — no monthly subscription.
Trial/subscription status in admin tools
Support staff can now see each gateway's trial or subscription status.
Stronger account security
Improvements to how sign-in and gateway setup are protected behind the scenes.
Daily backups

JKBMSR launch
The customer dashboard, gateway sign-in, guided onboarding, gateway settings, live telemetry view, and firmware release tracking all went live for the first time.
Over-the-air firmware updates
Gateways can update themselves without a cable.
