Voice-controlled smart home automation
Low-cost home automation using Google Assistant, IFTTT, and Blynk with ESP8266 relays for real appliance control.
- Role
- Student engineer — Ball State University (undergraduate), 2019
- Stack
- Google Assistant, IFTTT, Blynk, NodeMCU ESP8266, Wi-Fi relays
Highlights
- Voice-driven commands decoded through Assistant, IFTTT, and Blynk.
- ESP8266 firmware coordinating Wi-Fi relays for household appliances.
- End-to-end path from utterance to hardware actuation with safety-minded defaults.
Problem
Off-the-shelf smart home kits were expensive or rigid; the goal was an affordable, extensible path for ordinary appliances.
Approach
Wired cloud automations into Blynk-controlled firmware on NodeMCU, using relays suited to load characteristics and adding guardrails around remote toggling.
Outcome
A working demonstrator that proved the integration stack and gave a template for incremental room-by-room expansion.
Technical notes
- Network recovery behaviors after Wi-Fi drops.
- Simple state feedback so cloud and device stayed loosely coupled.
