How it works
A gateway between your JK-BMS and the cloud.
The JKBMSR ESP32 gateway reads JK-BMS UART telemetry, sends secure updates to the cloud, and keeps firmware current through OTA releases.
Install the gateway
Connect the ESP32 gateway to the supported JK-BMS UART interface and power it from the battery system.
Connect to WiFi
The gateway uses HTTPS to communicate with the JKBMSR API. No inbound ports or VPN are required.
Claim in dashboard
Attach the device to your account and configure telemetry, OTA, and UART settings.
Monitor remotely
View battery telemetry and diagnostics from the authenticated dashboard at app.jkbmsr.com.
