Release Notes

Gen3 & AIO real-time support, connection stability, and better history navigation.

Gen3 & AIO inverter real-time data

• Gen3 hybrid and All-in-One inverters now update every 10 seconds — the same as Gen2
• Root cause identified and fixed: a CRC calculation error in local Modbus requests caused Gen3/AIO dongles to silently discard them; corrected CRC now matches what the dongle expects
• Confirmed working via wire capture — responses arrive in ~250ms

Connection stability

• Fixed recurring "lost connection / no data for 75s" drops on all inverter models — the dongle's heartbeat is now acknowledged correctly, keeping the session alive

History navigation

• Week, Month and Year views now show one period at a time with ‹ › arrows, matching the Day view
• Year labels omitted when showing the current year — cleaner and less cluttered

A clearer hourly view, power in watts, and built-in backups.

Scrollable hourly breakdown

• The hour-by-hour chart now scrolls left/right on mobile, so each hour is easy to read instead of crushed
• The kWh axis stays pinned while you scroll, and battery % is labelled right on the line
• Opens centred on the busiest part of the day

Charge & discharge power in watts

• Optionally show and set charge/discharge power limits in watts instead of %
• Set your inverter's max charge/discharge power in Settings to match the official app

Backup & restore

• Automatic daily database backups (gzipped, kept for a configurable number of days)
• Download a backup to move your history to another machine
• Restore from a backup file — ideal when switching computers

Fixes

• Refined Gen3 connection so it works reliably without the official app open
• Fixed a startup crash on the very latest Python by pinning a compatible Flask

Gen3 inverter support, plus a quieter, faster, more dependable core.

Gen3 inverter support

• Now works with Gen3 / HV hybrid inverters as well as Gen2
• Automatically detects how your inverter communicates — no configuration needed
• Gen3 models stream their data continuously; the dashboard now reads that stream directly

Stability & polish

• Now runs on a proper production web server (Waitress) — faster and more reliable, especially when viewed by more than one device or over a remote tunnel
• Much quieter logging — the odd momentary inverter read no longer fills the log with scary-looking errors; only genuine, sustained outages are reported
• More robust Windows installer and a clean, reliable uninstall

Go hour-by-hour, and see exactly what your home used.

Hourly breakdown

• Tap any day in the Day view to drill into an hour-by-hour breakdown
• 24-hour chart of solar, home, grid and battery energy
• Battery state-of-charge plotted as a line across the whole day
• Step between days with the ‹ › arrows

Home consumption

• New "Home" series on every history chart — see what the house actually used
• Works across your whole existing history, no waiting for new data

Improvements & fixes

• Solar daily totals now include both PV strings, so figures are accurate for dual-array systems
• Battery & inverter temperatures are now logged for future trend views
• Safe in-place upgrades — your settings and history are always preserved, with automatic backups on Linux
• More reliable Windows installer that finds Python even without "Add to PATH"

The big one — the dashboard can now control your inverter, not just watch it.

Inverter Control

• Switch operating mode between Dynamic (Eco) and Storage
• Enable or disable battery charging and discharging on demand
• Edit charge and discharge time slots with simple time pickers
• Set charge target SOC and discharge reserve floor with sliders
• Adjust charge and discharge power limits
• Toggle export behaviour between Demand-only and Export-excess
• Every control screen reads the live inverter state before you change anything

Activity Log

• A complete timeline of every command sent and its result
• Inverter status changes logged automatically (Normal / Warning / Fault)
• Connection loss and recovery events recorded
• Colour-coded by type for quick scanning

Improvements & fixes

• Weather now refreshes reliably — server polls Met Office on a configurable interval (default 30 min), badge updates every 10 minutes
• Fixed an occasional layout glitch where the energy flow could bunch up on load
• Added a Cancel button (and tap-outside / Escape) to the password prompt
• Weather observation time now shown on the badge
• Grid shows "Idle / 0 W" when import or export is under 10 W

The first public releases — a complete local monitoring dashboard.

Monitoring

• Live energy flow visualisation with animated particles between solar, home, battery and grid
• Real-time power readings, battery state of charge, temperatures and voltage
• Today's totals for solar, grid import/export at a glance
• Smart flow logic — correctly shows grid-to-battery vs grid-to-home

History

• Day, week, month and year history charts
• SQLite database storing up to two years of readings
• Per-series totals shown directly on the chart bars

App & platform

• Progressive Web App — installs full-screen on iPhone and Android
• Optional Met Office weather widget
• Password-protected settings screen for all configuration
• Runs as a service on Windows and Linux/Raspberry Pi, starting automatically on boot
• Live-data smoothing to suppress momentary zero-reading blips
