CEPOWER is a complete monitoring platform for JK-BMS–based battery systems. It is designed for users who need continuous, permanent visibility — not temporary Bluetooth scans or limited manufacturer apps.
Whether you operate a single DIY battery, install systems for clients, or manage batteries at scale, CEPOWER provides a unified way to monitor, analyze, and react in real time.
The system uses an ESP32 gateway that connects to the JK-BMS via Bluetooth and exposes the data locally or remotely over Wi-Fi, making the battery accessible anytime — not only when you stand next to it.
Most JK-BMS users rely on mobile apps that only work when Bluetooth is connected, provide limited history, and stop monitoring once the phone disconnects.
CEPOWER replaces this model with a permanent monitoring gateway:
DIY & Home Users
Installers & Technicians
Battery Companies & Brands
Enterprise & Large Deployments
CEPOWER supports monitoring multiple batteries simultaneously. Batteries can be viewed individually or combined into a total system view.
Installers and companies can oversee multiple client systems from a single interface, without mixing data or access.
CEPOWER includes a flexible rule-based notification system. Alerts can be triggered by battery conditions and thresholds:
CEPOWER does not require user registration or cloud accounts. Access is based entirely on a Device ID.
This makes the system simple, secure, and suitable for private or offline-first environments.
CEPOWER JKBMS Monitor works with any ESP32 module that includes both Wi-Fi and Bluetooth. These two features are mandatory and cannot be substituted.
✔ Bluetooth (BLE / Classic) → communication with the JK-BMS
✔ Wi-Fi → live monitoring, history, notifications, and firmware updates
CEPOWER does not rely on high CPU speed, large RAM, or PSRAM. All supported ESP32 variants run CEPOWER at the same performance level. Bigger memory or newer chips do not make CEPOWER faster or more accurate.
All ESP32 modules listed below include both Wi-Fi and Bluetooth. Models marked as Tested were verified in real CEPOWER installations. Others are expected to work based on official Espressif specifications.
| ESP32 Module / Board | Chip Family | Wi-Fi | Bluetooth | Status |
|---|---|---|---|---|
| ESP32-WROOM-32 | ESP32 (Classic) | ✅ | ✅ Classic + BLE | Tested & Recommended |
| ESP32-WROVER-E | ESP32 (Classic) | ✅ | ✅ Classic + BLE | Tested & Recommended |
| ESP32-DevKitC | ESP32 (Classic) | ✅ | ✅ Classic + BLE | Works |
| ESP32-WROOM-32E / 32U | ESP32 (Classic) | ✅ | ✅ Classic + BLE | Works |
| ESP32-S3-WROOM-1 / 2 | ESP32-S3 | ✅ | ✅ BLE 5 | Expected to work |
| ESP32-C3 (all variants) | ESP32-C3 | ✅ | ✅ BLE 5 | Expected to work |
| ESP32-C6-WROOM-1 | ESP32-C6 | ✅ Wi-Fi 6 | ✅ BLE | Expected to work |
The ESP32 variants below are not compatible with CEPOWER due to missing hardware features. These limitations cannot be fixed by firmware or software updates.
| ESP32 Variant | Wi-Fi | Bluetooth | Why it does NOT work |
|---|---|---|---|
| ESP32-S2 | ✅ | ❌ | No Bluetooth → cannot communicate with JK-BMS |
| ESP8266 | ✅ | ❌ | No Bluetooth support |
| ESP32-H2 | ❌ | ✅ BLE only | No Wi-Fi → cannot upload data |
| ESP32-P4 | ❌ | ❌ | No Wi-Fi and no Bluetooth |
| ESP32-Solo-1 | ✅ | ❌ | Bluetooth removed to reduce cost |
Bottom line:
Buy any ESP32 with built-in Wi-Fi and Bluetooth.
