⚡ Dad Complains About Electric Bill, So I Built Him an Energy Dashboard and Found the Panels Lied ⚡

说明与用途

构建了一个太阳能仪表板，整合了实时面板数据、家庭用电和账单，发现面板映射错误和微逆变器故障，解释了高额电费。

问题

High electric bill and uncertainty about solar panel performance.

结果

The dashboard revealed that several panels were mis‑mapped and underperforming, and that two microinverters were dead, explaining a significant portion of the high bill.

工作流

• Collect live panel data from Enphase gateway every minute
• Collect smart plug data from Home Assistant
• Fetch historical solar data from Enphase cloud API
• Download ComEd Green Button bills
• Retrieve PVWatts expected production
• Store data in Upstash Redis
• Generate problems list (dead microinverters, underperforming panels, token expiry, usage spikes)
• Run Gemma 3 4B locally to create a plain‑English briefing every 6 h
• Publish dashboard on Vercel with password protection

证据

Live data from our solar panels, straight from the Enphase gateway on our home network, every minute, down to each individual panel
