HelioPeak vs Modbus TCP FieldKit

HelioPeak gives you a clean, modern way to follow your solar production and consumption with your PVOutput.org data, on iPhone, iPad and Mac. DASHBOARD & CHARTS • Dashboard with live power, today's production and peak, self-use, grid export and import, and estimated revenue • Production, Consumption and Combined views in the charts • Interactive charts for Day, Week, Month, Year and Total, with arrows to step through each period and a date picker to jump anywhere • Your own target line, from the monthly estimates you entered on PVOutput, in the Week, Month and Year charts COMPARE • Lay yesterday, the same day last year, your record day or any date behind the day you are looking at • Show the same period of another year behind your Week, Month and Year bars, with the difference in percent • Put up to four of your systems side by side, per kWp so different sizes compare fairly, also their day curves • Year-over-Year Comparison of today, this month and the year to date, with percentage changes and a shareable one-page PDF SIRI & SHORTCUTS • Ask how much your system produced today, yesterday or this month, without opening the app • The same questions in the Shortcuts app, for any of your systems SOLAR MOMENTS • Shareable cards for records, milestones, quarter and year recaps, installation anniversaries and sunny streaks, with a notification • Statistics: all your moments at a glance, the records to beat and the next milestone INSIGHTS & REPORTING • Annual Report PDF: a multi-page A4 report with totals, monthly breakdown, peak days and yield, in all six app languages • Monthly Report: after each month, a one-page PDF per system, the month against last year and your estimate • Export for AI: one file with your history for the AI assistant of your choice • CSV and JSON export of your daily production and consumption • System health dots: see at a glance whether each system reports normally • Specific Yield (kWh/kWp per year) and Yearly Average, the solar industry's benchmarks • Estimated revenue from your electricity price, CO₂ savings and a tree equivalent iPAD & MAC • Native iPad layout with sidebar, Inspector panel, year heatmap and keyboard shortcuts • Also runs on Macs with Apple silicon (the iPad version) NOTES & TIMELINE • Add notes to any day: cleaning, weather, panel issues • Browse them in the Timeline; they sync across your Apple devices through iCloud WIDGETS • Home Screen widgets in three sizes, the large one with today's curve; each widget can show a different system • Lock Screen widgets with today's production UNDER THE HOOD • Smart caching: works offline, with up to 80% fewer API calls • Built-in demo system: try the app before connecting your own PRIVACY FIRST HelioPeak talks directly to the PVOutput API with your own read-only API key. Your key is stored on your device and goes only to PVOutput. No ads, no tracking. Anonymous usage statistics and crash reports help improve the app; you can switch them off in Settings. HOW IT WORKS 1. Create a read-only API key on pvoutput.org (Settings, API Access) 2. Enter your System ID and API key in HelioPeak 3. Explore your solar production and consumption HelioPeak never sees your PVOutput password. MULTIPLE SYSTEMS The free version supports one PVOutput system. Unlock unlimited systems with a single in-app purchase. HelioPeak is not affiliated with PVOutput.org. Revenue estimates are for information only.

Modbus TCP FieldKit puts a professional Modbus TCP toolkit in your pocket. Commission equipment in the field, validate setups in the lab, or troubleshoot home automation — all from your iPhone. • Connect to any Modbus TCP or RTU over TCP device — read coils and registers, monitor data blocks in real time • Modbus RTU over TCP — reach RS-485 devices through Wi-Fi or Ethernet converters in transparent mode (for example Elfin EW11, USR or Waveshare). If a read times out, the app offers to try the other framing with a single read. • Find devices and Scan Unit IDs on your own Wi-Fi subnet — ports 502, 1502, 8899 and 4196. Each device is read once and nothing is written. • Chart every monitored value — the app keeps the last 600 points or 1 hour per value while it is open — and Export CSV through the system share sheet. • Save device profiles for one-tap reconnection to frequently used endpoints • Write with confidence — every write operation requires your explicit confirmation • Built-in foreground simulator — run editable coils and holding registers for testing • Track active connections and review bounded local logs kept on your device • All data stays local — logs and diagnostic exports are sanitized by default Requires Local Network access for device communication. RS-485 devices connect through a Wi-Fi or Ethernet converter in transparent mode. Default server port is 1502. Background server operation and port 502 support pending device validation.
