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

Описание и применение

Создана панель мониторинга солнечной энергии, которая объединяет данные о производстве, потреблении и счетах, выявив неверно отображаемые панели и неисправные микроинверторы, что объясняет высокий счёт за электроэнергию.

Задача

High electric bill and uncertainty about solar panel performance.

Результат

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.

Рабочий процесс

• 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

Доказательства

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