Tiny Growatt Monitor

TinyGrowattMonitor is a lightweight, privacy-friendly companion app for Growatt solar inverter owners. Connect with your existing Growatt account and keep a real-time eye on your system directly from your Android phone or home screen widget.

FEATURES

• Live dashboard — battery state of charge, grid import/export, solar production and home consumption updated on every refresh
• Home screen widget — glanceable battery status without opening the app; refreshes automatically in the background
• Battery alerts — get a notification when your battery drops below a configurable threshold
• Auto storage-ID detection — no manual configuration needed; the app finds your storage device automatically after login
• Offline cache — last known data is always shown even without a network connection
• Dark mode — fully adapts to system light/dark theme
• Minimal permissions — only the internet permission is required; no location, no contacts, no ads

HOW IT WORKS

Log in with your existing Growatt OpenAPI credentials (the same username and password you use on the Growatt website or app). TinyGrowattMonitor communicates directly with the official Growatt OpenAPI and stores your session securely on-device, minimising repeat logins.
