PowerCost

PowerCost brings real-time electricity cost tracking and detailed historical power analytics directly to your Stream Deck. Build a personalized dashboard to stay on top of your energy usage in an era of rising electricity prices.

KNOW YOUR RUNNING COST

Instantly view exactly how much it costs to keep your PC or Mac running. PowerCost uses native, hardware-level sensors to read live system wattage seamlessly in the background.

GLOBAL PRICING ENGINE

No need to look up conversion charts. PowerCost features a built-in database of national average electricity prices for 16 major countries (including the UK, USA, Germany, France, and more). Need more precision? Simply flip the Pricing Mode to "Manual" and enter the exact rate from your latest energy bill.

FLEXIBLE PROJECTIONS

Configure each key independently to show your projected cost over time. Set your action to calculate live costs running Hourly, Daily, Weekly, or Monthly to accurately understand its impact on your upcoming electricity bill.

DEEP ANALYTICS & AVERAGING

System wattage fluctuates constantly. PowerCost intelligently logs your live power draw in the background and averages the historical data over your selected time window, providing a smooth and highly accurate running cost projection.

EXPORT TO CSV

Track your efficiency over time. Use the "Export to Desktop" button in the property inspector to dump your exact second-by-second historical power usage directly to a CSV spreadsheet for deep analysis.

NEO INFOBAR SUPPORT

Full support for the Stream Deck Neo display. Place the PowerCost action on a Neo device to see a beautifully formatted live ticker of your electricity cost right on the Infobar.

Add multiple instances of the PowerCost action to your canvas to monitor Hourly, Daily, and Weekly costs side-by-side.

Requires Windows 10 version 1903 or later, or macOS 13.0 or later. Fully compatible with Stream Deck 6.5+ and Stream Deck Neo (requires Stream Deck 7.6 or later for Infobar support). Hardware sensor availability and accuracy may vary based on PC motherboard, Windows permissions, drivers, and specific Mac silicon.

PowerCost 1.1.0.0

What's new

- Centralized Singleton Monitor: Decoupled hardware polling from UI instances, ensuring a single unified polling loop across multiple keys and the Neo Infobar.

- Delta-t Numerical Integration: Computes energy and cost from true elapsed milliseconds, eliminating double-counting and sleep-wake distortions.

- High-Precision Telemetry: Stores sample costs up to 9 decimal places in CSV exports, preserving micro-costs on low-power idle draw (< 1.63 W).

- Sleep & DarkWake Artifact Filtering: Detects macOS Power Nap / DarkWake sensor states to prevent false 0.00 W readings from logging to history.

- Persistent Tariff Cache: Automatically persists configured electricity rates to prevent fallback dips on system wake or restart.

- In-Memory Rolling Window: Instant historical average calculation with zero disk read overhead during regular polling intervals.
