Complete sigenstor-control T05 — pymodbus client register map
Task: Implement async pymodbus client with register map for Sigenergy SigenStor home battery system. Requirements: parse HA sigenergy integration constants, implement backoff + asyncio.Lock serialised writes, register all Modbus registers needed for monitoring and control. This is Phase 1 milestone — battery SoC visible via API.\n\nFiles to create/modify:\n- /opt/data/sigenstor/app/services/modbus.py (new: async client)\n- /opt/data/sigenstor/app/constants/reg_map.py (new: register map from HA integration)\n\nAcceptance criteria:\n1. AsyncModbusClient class with connect/close/disconnect lifecycle\n2. asyncio.Lock serialises all writes to prevent concurrent Modbus transactions\n3. Backoff on connection errors (exponential, max 5 retries)\n4. Register map covers: SoC, voltage, current, power, battery temperature, PV power, grid import/export\n5. Basic test coverage for client lifecycle and register reads

Ralph picked at 2026-07-01T05:35Z. Returned infra-OOMKILLED to queued (low priority, deferred). Focusing on T05 pymodbus client register map — Phase 1 milestone for sigenstor-control. Next concrete step: examine repo structure and identify HA sigenergy integration constants to parse.
Note (2026-06-29T16:13:40Z)
BLOCKED at 2026-07-01T05:35Z. No sigenstor repo exists on disk (search_files returned 0 results). Task requires /opt/data/sigenstor/ with HA sigenergy integration constants to parse — neither the repo nor the source files exist yet. Cannot proceed without repo scaffolding and register definitions. Stuck guard triggered: 5 notes, zero tool calls produced results. Slack DM sent to C0AU44L25RS per protocol.

Ralph iteration at 2026-07-01TxxZ. Active task — implementing T05 pymodbus client register map for sigenstor-control Phase 1 milestone (battery SoC visible via API). Repo found at /opt/data/repos/sigenstor-control/. Existing modbus_poller.py already has async ModbusPoller class with basic register map and connect/close/read_telemetry. Plan: enhance with exponential backoff, asyncio.Lock serialisation of writes, add missing registers (voltage, current, battery temp), create reg_map.py constants module with HA sigenergy integration data.
