"Alexa, turn on the A/C."
Five years ago, smart homes in Sri Lanka cost Rs. 1 Million+. Today, thanks to WiFi ecosystems like Tuya and Sonoff, you can smarten up a house for under Rs. 100,000.
It's not just a gimmick; it's about energy saving and security.

1. The Ecosystems: Tuya vs Sonoff
Forget expensive proprietary systems (Control4) unless you are ultra-wealthy. The standard today is WiFi-based IoT.
- Tuya / Smart Life: The biggest platform. Thousands of brands (Moes, Zemismart) use it. Works with Alexa/Google. App is excellent.
- Sonoff (eWelink): Great for DIY enthusiasts. Reliable hardware.
- Apple HomeKit: Premium, works seamlessly with iPhone, but hardware is 3x pricier.
Recommendation: Stick to Tuya compatible devices for maximum variety in Sri Lanka.
2. Must-Have Smart Features
- Smart Switches: Replace normal wall switches. Control lights via phone/voice. Set schedules ("Turn on porch light at 6 PM").
- Smart IR Blaster: A tiny Rs. 3,000 puck that sits in the room and controls your "dumb" A/C and TV. "Alexa, set A/C to 24 degrees."
- Smart Gate: Open your roller gate from office for a courier.
- Energy Monitoring: See exactly how much power your fridge/geyser is using.

4. Installation Guide
- Neutral Wire Issue: Most old SL homes don't have a neutral wire in the switch box. You need "No-Neutral" smart switches (require a capacitor) OR pull a neutral wire (better stability).
- WiFi: You need a strong 2.4GHz WiFi signal everywhere. A mesh router system (Deco/Tenda) is recommended.
