5pm summer spike: 2.54 kWh/hr avg — 3× the overnight base
The 5pm hour (14–18:00 on-peak window) averages 2.54 kWh/hr in summer — the single worst hour. This is HVAC running full blast on a hot afternoon combined with everyone arriving home, cooking, and appliances firing. The on-peak rate multiplier makes this the highest-cost period of the week.
Overnight base is 800–900W — roughly 2× what's expected
The 2–4am floor is 0.59–0.73 kWh/hr (590–730W) in winter and 0.97–1.05 in summer. Expected for a house this size is 200–350W base + HVAC runtime. The gap implies phantom loads or the DAIKON running frequently overnight even in mild weather. Worth checking the Skyport app's overnight runtime logs.
6–8am morning ramp is sharp and consistent across all seasons
Usage jumps from 0.8 to 1.3–1.5 kWh/hr at 6am every season — clearly tied to family wakeup (lights, hot water, breakfast). This is off-peak in all seasons. No action needed, but it's useful confirmation that the profile is household-activity driven, not always HVAC.

Behavior Shift — Estimated Savings
Based on $9.72/kW demand rate · annualized from 13 billing periods · demand charge alone, not counting energy savings
| Target | Required behavior | Periods affected | Annual savings | Effort |
|---|
Key insight: The dryer (~4–5 kW) running while the HVAC is cooling (~3–4 kW) is the primary demand spike mechanism. Scheduling laundry for after 10pm or before 8am on hot days is the single highest-leverage behavior change available.

Pre-cool strategy: biggest on-peak lever available
Set DAIKON to 70–71°F by 1:30pm on summer weekdays. Thermal mass carries the house through the 2–7pm on-peak window at a raised setpoint (76–78°F). At the on-peak rate vs off-peak rate differential, this saves an estimated $50–120/yr depending on summer severity. Available directly in Skyport Home as a schedule setpoint.
Demand charge: never run dryer + HVAC peak cooling simultaneously
An electric dryer pulls 4–5 kW. Your HVAC compressor is 3–4 kW. Together on a hot evening = 7–9 kW in one hour, which sets the month's demand charge. This is the #1 demand reduction lever. Schedule the dryer for after 10pm or before 8am — Skyport won't control the dryer but pairing the two schedules manually is the key move.
Hot weekend afternoons are your worst demand risk
June 13 (Sat, 92°F) set the $234 bill's demand. On hot weekend afternoons (Sat/Sun, 85°F+), proactively pre-cool to 71°F by noon — before you'd normally notice the house warming up. The Skyport weekend schedule should match summer weekday pre-cool timing.
