Unattended access
For the email / no-live-call flow: a customer authorises your passkey once, and you can dial in for 48 hours. Your device is never contacted directly — nothing here can act on a system until a customer authorises this exact key.
Your access key
A passkey on this device (Touch ID / Windows Hello). The private key stays in the secure enclave; you only ever share the public key below.
— Authorised systems
Systems whose owner has authorised your key. Each expires 48 hours after it was granted.

Per-battery cell data
No battery packs detected yet. The agent reads each pack’s BMS at unit IDs 0x32+ on every telemetry tick — pack cards will appear here automatically.
If batteries are fitted but nothing shows up, the pack BMS is most often asleep because the battery is at a low state of charge — wake it (e.g. force-charge) and the cells reappear. Otherwise the BMS bus may not be reporting: check the Registers tab for the raw inverter-side battery view (input addresses 50..80), or call STS for diagnosis.
Cell voltage history
Each line is one cell over time. A failing cell sags away from the pack — it's drawn red; a high cell blue. The agent records a sample a minute while it's running (last 48h).
No history recorded yet — leave the app running and check back in a few minutes.

Detected capabilities
Engineer-grade settings forms (Max Output %, Export Priority, EPS Enable, Restart Inverter, Time/Date) ship in the next iteration — they each need a read-back-verified write path. For now use the Registers tab.
Grid & export settings
The registers on this tab — Grid Code, Export Limit (G98/G99), Import Limit, G100 Enable, EPS — are controlled by your DNO agreement. Writing them incorrectly can put your installation out of compliance, fail next inspection, and in extreme cases trip the inverter into permanent fault state.
This tab is read-only by design. Engineer-grade writes are gated behind a --allow-dno-override flag at agent startup plus a separate confirmation in the dashboard — neither of which ships in this iteration. Raw access via the Registers tab works at your own risk.

Live grid voltage + frequency arrive in the next telemetry extension. For raw values now, see Registers — input addresses 5 (V_AC1), 13 (F_AC1), 58 (I_GRID_PORT).
Where the config lives
- HR 128 · MaxExportPowerW — the G98/G99 limiter (typically 3680 W single-phase)
- HR 113 · TodayImportKWh · u16 / 10
- HR 114 · TodayExportKWh · u16 / 10
- HR 26 · GridPortMaxPowerOutput (read-only on most firmware)
- HR 115 · IslandCheckContinue (G100 / anti-islanding behaviour)
All five readable via the Registers tab's bulk dump. Write paths come with the DNO-override flag.
Meters & CT direction
CT direction flips are the #1 reason power values look backwards. If customer reports "the app says I’m exporting when I’m importing" or vice versa, that’s almost always one of HR 48 or HR 49 set wrong for the installed meter.
Read the current values via the Registers tab first — don’t toggle blind. A wrong flip here can make every chart on the system look correct in shape but wrong in sign, and customers won’t notice until the bill arrives.

I_GRID_PORT (input 58) carries the live grid current; V_AC1 (input 5) and F_AC1 (input 13) the voltage and frequency. All visible in the Registers tab once we ship live input-register inspection.
Meter & CT config registers
- HR 47 · METER_TYPE —
0= CT (EM418),1= EM115 - HR 48 · REVERSE_115_METER_DIRECT — flip if using an EM115 meter and signs are wrong
- HR 49 · REVERSE_418_METER_DIRECT — flip if using a CT/EM418 and signs are wrong
- HR 50 · ENABLE_METERS — must be on for grid telemetry to populate
- HR 51 · IGNORE_EXTERNAL_GENERATION_METER — set on installs with separate generation metering
All five readable via the Registers tab. Writes need the customer-armed window like any other holding-register change.

Custom read
Temps live in Input: 41 heatsink, 56 battery, 76–79 cell-group sensors. Cells 60–75, PV 1/2/8/9/18/20. Read input addr 60 count 20 for all cells + cell temps in one go (input reads cap at 60).
Custom write requires armed [A] window
Decimal in — both Addr and Value (e.g. addr 53, value 1530), never hex. The Registers table’s Hex column is display-only — convert hex→dec before writing a value back.
Watch register read-only · live changes
Polls one register and logs every change live. Watch an input register (e.g. 56 battery temp, 76–79 cell-group temps) to catch a sensor drifting or flat-lining, or a holding register to see a setting change as it happens.
Not watching.
