Whether you are a maker, engineer, or student, manage your hardware with professional-grade precision.
Key Features:
Seamless BLE Connection: Fast and stable pairing with ESP32-C3 Mini and other Bluetooth LE modules.
Smart PWM Control: Adjust brightness or speed with a smooth slider (0-9 values).
Real-time Sensor Monitoring: Receive and parse JSON data from your hardware instantly.
Customizable UI: Add multiple devices, assign unique tags, and use custom icons for your setup.
Modern Design: Neumorphic Soft UI for a premium controlling experience.
Optimized for Makers:
Works perfectly with Arduino IDE and PlatformIO. Use our standardized JSON data model to monitor multiple sensors like LDR, DHT11, or Potentiometers in one single dashboard.


📶 WiFi & API Setup
Configure your ESP32's WiFi credentials and API key directly from the app via Bluetooth. No need to edit code — just connect, open the WiFi setup dialog, enter your SSID, password, and optional API key, and send. Your device will connect to your network instantly. ## Rankings - #1,207,264 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_ADSERVICES_AD_ID` - `android.permission.ACCESS_ADSERVICES_ATTRIBUTION` - `android.permission.ACCESS_ADSERVICES_TOPICS` - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.BLUETOOTH_CONNECT` - `android.permission.BLUETOOTH_SCAN` - `android.permission.CAMERA` - `android.permission.FOREGROUND_SERVICE` - `android.permission.INTERNET` - `android.permission.WAKE_LOCK` - `com.android.vending.BILLING` - `com.android.vending.CHECK_LICENSE` - `com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE` - `com.google.android.gms.permission.AD_ID` - `com.redant.blebuttonfi.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` ## Similar extensions and apps - [ESP32 BLE Communicator](https://chrome-stats.com/d/cc.lionbitble.esp32ble) — 406 users - [BLE Controller – Arduino ESP32](https://chrome-stats.com/d/com.circuitmagic.iot) — 72,954 users, 4.63 / 5 - [ESP32 BLE Connect-LionBit](https://chrome-stats.com/d/com.ESP32BLE.LionBit) — 2 users - [WELD: Bluetooth Controller](https://chrome-stats.com/d/com.fbp.weld) — 120 users - [DIYables BlueTooth STEM](https://chrome-stats.com/d/io.diyables.bluetoothstem) — 203 users - [ESP32C3 BLE](https://chrome-stats.com/d/appinventor.ai_d3ddyes.ESP32_BLE) — 444 users - [ESP32C3 BLE](https://chrome-stats.com/d/id.deddyes.esp32c3BLE) — 124 users - [Smart BLE Hub - BLE Controller](https://chrome-stats.com/d/com.ahkproduction.smartblehub) — 594 users - [LED Controller](https://chrome-stats.com/d/com.opc.ledcontroller) - [BTControl: Arduino ESP32](https://chrome-stats.com/d/com.tabba.btcontrol) — 6,941 users - [BLEC - BLE Control for ESP32](https://chrome-stats.com/d/in.ideazero.blec) — 11 users - [ESP32 Bluetooth button control](https://chrome-stats.com/d/worldthem.com.smarthomearduinobluetoothcontroller) — 4,546 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.redant.blebuttonfi)
