The Hidden Cost of Standby Power (And How to Fix It)

That little red light on your TV? It's costing you money 24/7. Standby power—sometimes called vampire power or phantom load—is the electricity devices consume when they're "off" but still plugged in.

The Scale of the Problem

The average UK home wastes £80-140 per year on standby power. Common culprits include:

Identifying Vampire Loads with OhmMy

If you have a smart meter connected to OhmMy, you can identify standby consumption:

The Overnight Test

1. Note your power consumption at midnight
2. Check again at 6am (while sleeping)
3. The baseline is your standby load

In OhmMy, go to Analytics > Consumption > Time of Day to see your overnight baseline automatically calculated.

Real-Time Detection

Watch your live power reading while you:

1. Turn off a device normally
2. Note any remaining draw
3. Unplug it completely
4. See the difference

Quick Wins

1. Smart Power Strips

Use smart power strips that cut power to peripherals when the main device turns off:

• TV + soundbar + games console on one strip
• Computer + monitor + printer on another
• One button (or automation) kills everything

2. Schedule Standby Devices

Some devices need standby for functionality (DVR recording, smart home hubs). Schedule them:

Router: Always on (necessary)
Set-top box: 6am - 11pm only
Games console: Off when away

3. Replace Energy Vampires

When replacing appliances, check standby ratings:

• Good: < 0.5W standby
• Acceptable: 0.5-1W standby
• Poor: > 1W standby

EU regulations now limit most devices to 0.5W standby, but older devices can be much worse.

The Network Equipment Dilemma

Routers, mesh WiFi, and smart home hubs typically need to stay on. Minimize their impact:

1. Consolidate devices - One good router vs. router + extender + mesh
2. Use efficient models - Modern WiFi 6 routers are more efficient
3. Disable unused features - Guest networks, unused bands

Measuring Your Progress

Track your standby reduction in OhmMy:

1. Go to Analytics > Efficiency Score
2. Check your "Baseload" metric
3. Set a target (aim for < 50W household baseload)
4. Monitor weekly progress

The 80/20 Rule

Focus on the big wins first:

1. Games consoles - Biggest offenders, easy to switch off
2. Set-top boxes - Schedule or replace with streaming
3. Desktop computers - Enable proper sleep modes
4. Multifunction printers - Unplug when not in use

Beyond Standby

Once you've tackled standby power, explore:

• LED lighting upgrades
• Heating schedule optimization
• Appliance efficiency ratings

Every watt saved is money back in your pocket—and less carbon in the atmosphere.
