● Real-Time Telemetry Cloud

JKBMSR

Remote JK-BMS monitoring without the local stack.

A plug-and-play ESP32 gateway and cloud dashboard for battery owners, installers, and RV solar systems.

Field Telemetry

Live pack visibility from the field.

SOC, voltage, current, and cell balance in one dynamic dashboard — no Home Assistant, no VPN, no port forwarding required.

Built for Reliability

Built for people who need the pack online, not another server to babysit.

Focused tooling for JK-BMS deployments — from first flash to remote alerts.

📡

Monitor from anywhere

See JK-BMS status remotely without a VPN, port forwarding, or Home Assistant.

Browser flash & claim

Flash over USB in Chrome, join Wi‑Fi with Improv, then claim the device in one flow.

🔔

Remote alerts

Know when pack conditions need attention before a site visit becomes urgent.

🔒

Signed OTA updates

Keep gateways current with signed metadata, hash verification, and remote delivery.

🛠️

Installer friendly

Built for repeatable deployment across off-grid, RV, solar, and small energy systems.

🔋

JK-BMS focused

Version 1 stays on JK-BMS so compatibility can be tested deeply instead of broadly.

Fast Onboarding

Three steps from box to dashboard.

Flash in the browser, join Wi‑Fi, claim the device — then monitor from anywhere.

Flash the gateway

Use Chrome or Edge at cdn.jkbmsr.com/flash — no Arduino IDE required.

Connect Wi‑Fi

Improv Serial prompts for your network over the same USB cable. SoftAP fallback if you are in the field.

Claim and monitor

Finish at app.jkbmsr.com/onboard with the device ID and claim code already filled in.
