Build a Custom WiFi Power Strip with Per-Outlet Current Monitoring Using ESP8266

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Tired of overpriced smart plugs that give you no insight into how much power your appliances actually draw? This kit lets you build a fully functional WiFi power strip from scratch. You’ll use an ESP8266 NodeMCU to independently switch four relay-controlled outlets and see each channel’s live current consumption—all through a web dashboard you create yourself.

What You'll Build

You’ll assemble a breadboard prototype that controls four outlets just like a smart power strip. Each outlet’s current (up to 5A) is measured by dedicated ACS712 sensors and displayed on a compact OLED screen. The ESP8266 hosts its own dashboard, so you can switch any outlet and read real‑time current from any phone or laptop on your home network—no cloud accounts, no subscription.

What You'll Learn

• Program an ESP8266 to serve a responsive web dashboard without relying on external cloud services
• Interface 5V relay modules with a 3.3V microcontroller using diode protection and level‑safe logic
• Read ACS712 current sensor data and calibrate it for accurate AC current measurement
• Design a breadboard layout that safely separates low‑voltage digital signals from high‑current relay control
