Changelog
[2.0.1] – 2026-04-01
Fixed
∙ Connection drops – the PowerOcean Plus closes idle TCP connections after a short timeout, causing poll cycles to fail with “Connection unexpectedly closed”. The coordinator now closes the connection after every poll cycle and opens a fresh one on the next, eliminating stale connection errors entirely.

Changelog

[2.0.0] – 2026-03-31

Added

House Power sensor (register 40519) – previously incorrectly listed as cloud-only
Grid Power sensor (register 40521) – previously incorrectly listed as cloud-only
Solar Power sensor – calculated from active PV strings (more reliable than register 40523)
Per-string PV Power sensors (W) for strings 1/2/3, calculated from current × PV voltage
PV Voltage Global sensor (register 40598)
Serial Number and Operation Mode diagnostic sensors
Battery Nominal Capacity sensor
Min SOC Limit, Battery Temp Warning Max/Min diagnostic sensors
Inverter power limit sensors (nominal + current)
Max Battery Discharge Power and Max Charge Power sensors (calculated from module count)
House Consumption Today/Total energy sensors (calculated from energy balance)
Solar Yield Today/Total energy sensors
Configurable battery capacity – workaround for unreliable register 40528
Configurable PV string count (1–3) – unused strings are ignored
Phantom current filter – string currents below 0.05 A are treated as 0
Configurable poll interval (5–60 seconds) via UI
Options Flow – all settings editable after setup via Configure button
Debug logging toggle in HA UI via manifest.json loggers field
German and English translations for all config/options flow fields
Heartbeat check at the start of each poll cycle – detects inverter unavailability immediately
Automatic reconnect after inverter restart or network interruption – stale TCP connections are detected and cleanly closed, with reconnect on the next poll

Changed

Switched from individual register reads to block reads (5 requests per poll cycle instead of ~25)
Inverter Temperature register corrected to 40592 (was incorrectly mapped to 40600)
inverter_ac_power (40530) now read as direct INT16 Watts (division by 100 removed)
Power limit register offsets corrected (40546/40548/40550/40552)
Registers 40550/40552 replaced by calculated values (were unreliable)
const.py cleaned up – individual REG_* constants removed, block addressing used in coordinator
sensor.py uses UnitOfApparentPower.VOLT_AMPERE instead of hardcoded "VA"

Fixed

Grid power and solar power returning 0 due to incorrect register mapping
Battery remaining energy returning double the correct value (wrong scale factor)
Phantom voltage on unconfigured PV string 3

Removed

Unused ConfigEntryNotReady import from __init__.py
Unused REG_* constants from const.py
pv1_today / pv2_today individual string energy sensors (not available via Modbus)
