The Phantom Power Problem

Every appliance left plugged in — even when "off" — draws a trickle of power. Your geyser's thermostat cycles on/off all day to maintain temperature. Your set-top box never truly sleeps. Your router runs 24 hours. Together, this "phantom load" costs Indian households ₹480–720 per month — invisibly, silently, every day.

A ₹600–1,000 smart home setup can eliminate most of this waste within the first billing cycle.

The Phantom Power Audit: What's Stealing From You Right Now

Phantom power — also called "vampire power" — is electricity consumed by devices that appear OFF but remain plugged in. Indian homes lose 8–15% of total electricity this way. At ₹8/unit, that's ₹400–800/month wasted silently.
