Why this is a gap
Surfaced from a high-intensity complaint with clear willingness to pay and a specific, reachable audience.
The market
Home Assistant users with solar systems need net grid consumption calculations tailored to regional rules (e.g., Germany's EVU rules). No search volume, but the pain is specific to Home Assistant's active ecosystem.
Competition & the opening
Home Assistant has energy dashboards and community integrations, but none handle regional net metering rules. The gap is narrow: a calculator that correctly interprets local grid rules and feeds into existing Home Assistant energy tracking.
What's hard to build
Requires mapping regional net metering rules (Germany, US states, EU regions, etc.) into code; each region has different definitions of 'net consumption' and export incentives. Must stay current as regulations change. Feasibility 8/10 is high because the core math is straightforward; the hard part is maintaining regional rule data.
Why now
Home Assistant's energy dashboard is mainstream but lacks region-specific net metering logic that solar adopters need.
