Getting Started
SunFlow requires a Growatt inverter account. On the Connect screen, enter your Growatt credentials and select your region. Not sure which region? Try Global first — it covers most countries outside North America and China.

Widgets Not Showing Data
Widgets require an API token from your Growatt account:
- Log in at mqtt.growatt.com
- Go to Settings → Account Management
- Copy or generate your API token
- Paste it in SunFlow → Settings → Widgets section → Save
Note: Widgets are a Pro feature. A subscription is required to enable them.
Subscriptions
Pro — Home screen and lock screen widgets with push-driven data refresh every ~10 minutes.
Siri shortcuts are free for everyone, no subscription required. Pro includes a 7-day free trial. To restore a previous purchase, go to Settings → Restore Purchases.
Data Looks Outdated
Pro subscribers see widget updates every ~10 minutes via push notification. If data looks old:
- Open the app to trigger a manual refresh
- Check your inverter is online and communicating with Growatt's servers
- Verify your API token is still valid in Settings
App Crashes or Won't Load
Try force-quitting and reopening the app. If the issue persists:
- Restart your iPhone
- Check you're running the latest version of SunFlow
- Re-enter your credentials if you recently changed your Growatt password
Siri Shortcuts Not Working
Siri shortcuts are free for everyone — no subscription required. If shortcuts aren't responding, try opening the app once, then re-add the shortcuts via the Shortcuts app.
