The average home has 20+ connected devices — each one drawing power 24/7. Here's the exact cost of every smart device, and which ones are worth keeping plugged in.
Smart devices promise efficiency — but they're always listening, always connected, always drawing power. A single smart speaker draws 2-5W continuously. That's $3-$8/year per device. Multiply by 10-20 devices in a modern smart home, and you're looking at $60-$160/year just for "smart" convenience.
Worth the drain: Smart thermostat (saves 10-15% on HVAC), smart security (prevents break-ins), smart smoke detectors (safety). These pay for themselves many times over.
Questionable: Smart speakers in every room, smart fridge (you don't need WiFi on a fridge), smart mirrors. The convenience rarely justifies the 24/7 drain.
Not worth it: Smart plugs on devices that are rarely used, multiple streaming devices in guest rooms, smart water features with low usage.
1. Use smart power strips for entertainment centers — cut power to peripherals when the TV is off.
2. Schedule smart speakers — use sleep mode or smart plugs to cut power overnight.
3. Disable WiFi on devices you control locally (smart TVs, fridges).
4. Consolidate — one smart speaker per floor, not per room.
