Relay Switch

Motor Toggle is a Bluetooth Low Energy (BLE) companion app designed for direct wireless control and routine scheduling of electric motors, water pumps, solenoids, and electrical appliances via ESP32 micro-controller relay modules.

How It Works:
The app communicates directly with your ESP32 microcontroller using standard Bluetooth Low Energy (BLE). No internet connection or cloud account is required—all control data and schedules operate peer-to-peer on-device.

Key Features & Functionality:

• Direct BLE Power Switch: Instantaneous turn-on / turn-off control of connected electrical relays with real-time state confirmation.
• Autonomous Hardware Schedules: Configure routine on/off times with day-of-week repeat options. Schedules are automatically synchronized to the ESP32's non-volatile storage (NVS Flash) and onboard RTC clock so they continue running even when your phone is disconnected.
• Auto-Off Countdown Timer: Select preset countdown intervals (10, 15, 20, or 30 minutes) or set custom durations for automatic power shutoff—ideal for water tank filling and irrigation.
• Real-Time Signal Telemetry: Monitors live RSSI signal strength (-dBm) and connection state with automatic background reconnection.
• Emergency Cutoff: Tap the dedicated emergency cutoff switch for immediate power shutdown.

Hardware Requirements:
• Compatible with ESP32 micro-controllers running the Motor Toggle BLE relay firmware.
• Operates via Bluetooth Low Energy (BLE 4.2 / 5.0).
