Home Consumption

Understanding how much electricity your home uses — and when — is key to optimizing your energy system. The Home Consumption page shows you real-time and historical load data alongside your solar generation, so you can see exactly how self-sufficient your system is and where opportunities exist to improve it.

Current Home Load

The main tile at the top of the page shows:

• Current home consumption (kW) — your home’s real-time electricity demand, updated every 30 seconds
• Today’s total consumption (kWh) — cumulative energy your home has consumed since midnight

For Tesla Powerwall users, home consumption is not directly measured but is derived from the other values reported by your gateway:

home = solar_output + battery_discharge + grid_import − battery_charge − grid_export − vehicle_charging

This calculation ensures that energy flowing to your Wall Connector is attributed to vehicle charging rather than general home consumption, giving you a more accurate picture of your home’s actual load.

Power Timeline

A chart shows your home consumption over time, with TOU rate band shading overlaid in the background. This view helps you:

• Identify morning and evening usage spikes — HVAC startup, cooking, and lighting all show up clearly
• Correlate consumption peaks with grid import periods — see whether high-demand moments are coinciding with your battery being depleted or solar being unavailable
• Spot opportunities to shift loads to off-peak hours — running dishwashers, laundry, and EV charging during the unshaded off-peak window reduces your bill

Daily Consumption Summary

A table shows daily consumption totals for historical comparison:

• Date
• Total consumed (kWh) — everything your home used that day
• Solar-powered portion (kWh) — the share of consumption that was covered directly by solar or by battery charged from solar
• Grid-powered portion (kWh) — the share that required grid import
• Self-sufficiency % — the proportion of your home’s consumption powered by solar and battery combined; 100% means you ran entirely on clean energy that day

Self-sufficiency is the primary metric for understanding how well your solar and battery system is covering your home’s needs. High self-sufficiency days are typically sunny days where your battery was well-charged heading into the evening.

Solar vs. Consumption

A side-by-side comparison view shows daily solar generation versus home consumption for each day in the selected range. Two bars are drawn for each day — one for generation and one for consumption — making it easy to see the relationship at a glance:

• Generation exceeds consumption — you exported surplus energy to the grid that day, earning NEM credits
• Consumption exceeds generation — you imported energy from the grid that day to supplement solar and battery

Over a full billing cycle, the net of these days determines whether you’re a net importer or net exporter, which has significant implications for your utility bill.

Time Range Selector

Use the time range tabs to view consumption data at different levels of granularity:

• Today — minute-by-minute consumption chart for the current day
• 1h / 12h / 24h — sliding windows showing the most recent hour, 12 hours, or 24 hours of data
• 7 days — daily totals displayed as a bar chart, useful for week-over-week comparison
• 30 days — monthly trend showing daily consumption, solar coverage, and self-sufficiency Pro
