1. What is Daily Power Consumption?

Daily Power Consumption represents the total electrical energy used by devices over a 24-hour period, measured in kilowatt-hours (kWh). It's calculated by integrating power usage over time and converting to appropriate units.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \int \text{Power } dt \) — Integral of power over time (Watt-seconds or Joules)
• 3600 — Conversion factor from seconds to hours

Explanation: This formula converts the total energy usage (in Watt-seconds) to kilowatt-hours by dividing by 3,600,000 (3600 seconds/hour × 1000 Watts/kW).

3. Importance of Power Monitoring

Details: Monitoring daily power consumption helps identify energy usage patterns, detect inefficient devices, reduce electricity costs, and support environmental sustainability efforts.

4. Using the Calculator

Tips: Enter the total power consumption in Watt-hours (Wh) as provided by your Home Assistant system. The calculator will convert this value to kilowatt-hours (kWh).

5. Frequently Asked Questions (FAQ)

Q1: Why convert to kilowatt-hours?
A: Kilowatt-hours are the standard unit for electricity billing and energy consumption measurement, making it easier to understand and compare usage.

Q2: How accurate is this calculation?
A: The accuracy depends on the precision of your power monitoring equipment and the sampling frequency of your Home Assistant system.

Q3: Can I use this for solar production monitoring?
A: Yes, the same calculation applies to both energy consumption and production monitoring.

Q4: What's the difference between power and energy?
A: Power (Watts) is the rate of energy use, while energy (Watt-hours) is the total consumption over time.

Q5: How often should I check my daily consumption?
A: Regular monitoring (daily or weekly) helps identify usage patterns and opportunities for energy savings.
