See your home's energy flow live

WLED with the HomeWizard P1 usermod: purple pulses when you draw from the grid, green when your solar exports, calm white when balanced — speed follows the wattage.

Install from your browser

  1. Connect your ESP32 board to this computer with a USB data cable
  2. Click Install, pick the serial port, and wait ~2 minutes
  3. When prompted, enter your WiFi credentials — they're sent over the cable, no hotspot dance needed

Sorry — your browser has no Web Serial. Use Chrome or Edge on desktop. This page must be served over HTTPS.

Works with classic ESP32 and ESP32-C3 boards (e.g. Seeed XIAO ESP32-C3) — the right firmware is picked automatically. Chrome or Edge on desktop required.

Then, three small steps

  1. In the HomeWizard Energy app, enable the Local API for your P1 meter (Settings → Meters → your P1 meter → Local API)
  2. Open your new WLED device, set your LED count under Config → LED Preferences — the P1 meter is discovered automatically
  3. Select the Grid Flow effect on your segment, and save it as a boot preset
