WattStream

WattStream lets you monitor your Deye solar inverter directly over your local WiFi network. No cloud, no account, no subscription — just real-time data from your rooftop to your phone.

FEATURES
▸ Live Energy Flow Diagram Animated visualization showing how power flows between your solar panels, battery, grid, and home in real-time.

▸ Detailed Metrics
View solar production, battery charge/discharge, grid import/export, household consumption, daily energy totals, and system status — all updating every few seconds.

▸ Auto-Discovery
WattStream automatically finds your inverter on the local network. No manual IP configuration needed.
