The monitor, the dashboard, and the app.
We build the hardware that plugs into your battery, and the platform it reports to. One device, one account — from the RS485 port on your BMS to a push notification on your phone.
The hardware
ioVertex BMS Monitor
A small device that plugs into your battery and puts it on your phone. Fits in your palm, sets up in a couple of minutes.
What it does
- Plugs in
- Straight into your battery's spare data port. No soldering, no PC, nothing to open up.
- Sets up
- Connect your phone to the device's own WiFi, pick your network, done. No app needed to get it online.
- Reads
- Every cell voltage, temperature, charge level and fault your BMS reports — continuously.
- Sends
- Straight to your dashboard and phone, encrypted end to end.
- Stays current
- Updates itself over WiFi. You never have to plug it into anything again.

Live today
Battery & BMS Monitoring
Cell-level visibility into every pack you manage, published continuously, never gated.
Cell-level telemetry
Individual cell voltage, wire resistance, and temperature for every cell in the pack — not just pack-level averages.
Instant alerting
Threshold breaches push to the ioVertex Android app and the dashboard the moment they happen — no polling, no delay.
Historical analytics
Gap-aware history that correctly distinguishes a real offline period from a data gap, with CSV export for your own analysis.
Fleet management
Bulk device operations, tier reassignment, and CSV import for teams managing more than one device.
Device health
Online/offline status derived from live data, not a stale flag — you always know what's actually reporting right now.
Mobile app
The ioVertex Android app puts live status and push alerts in your pocket. iOS support is on our roadmap.
Under the hood
Platform capabilities
The infrastructure behind BMS monitoring isn't specific to batteries — it's built to carry the next kind of system we monitor too.
Secure device ingest
TLS-encrypted MQTT with per-device authentication and access control.
Multi-tenant access
Role-based access so operators, admins, and end customers each see exactly what they should.
Audit logging
Every device registration, role change, and configuration edit is recorded — who did what, and when.
What's next
Built to extend, deliberately not overpromising
We're not going to list monitoring categories we haven't shipped yet. What we can say: the platform underneath BMS monitoring was built generally on purpose, and we intend to point it at more than batteries over time.
