SmartLine BD is a smart home automation app designed for modern households. Control your lights, fans, water motor, and any electrical appliance directly from your Android phone — anytime, anywhere.
🔧 KEY FEATURES:
🏠 Complete Home Device Control
Turn any connected device ON or OFF with a single tap — lights, fans, water motor, and more. Full control of your entire home from one app.
⏰ Countdown Timer
Set quick countdown timers (10 min, 30 min, 1 hr) for any device. It switches off automatically when time is up — no manual effort needed.
📅 Date & Time Scheduling
Select a specific date and time to automatically turn ON or OFF any device. Schedule your water motor, fan, or lights days in advance and let the app handle the rest.
🪙 Earn & Unlock Premium Features

🛠️ Service-Based Activation
SmartLine BD works with a professional technician service team. After our team installs and configures your hardware (ESP32 or Arduino relay), your account gets activated for real-time device control.
Our Premium plan is not a subscription fee — it is simply our way of tracking your monthly hardware maintenance visit. Each month, our technician inspects and tests your hardware to ensure everything runs perfectly. Once the visit is completed, your plan is renewed for the next month. This helps us schedule your next maintenance visit on time and keep your smart home system in top condition.
☁️ Cloud Sync & Hardware Support
Connect ESP32 or Arduino microcontrollers via cloud synchronization. Your device status stays updated in real time across all sessions.
🔐 Secure Login
Sign in with your Gmail or phone number — both are supported for flexible and secure access. Biometric fingerprint recognition also available for faster login every time.
🌙 Theme Options
Choose Color Mode for a vibrant display or White Mode for better daylight readability — whichever suits you.
🌍 Built for Everyone
Designed to work with standard home hardware setups worldwide. Multi-language support included.
