Home Assistant ConfigFlow/OptionsFlow patterns—single-instance guard, schema validation, reload listeners, safe options handling without recursion.
Patterns for building Home Assistant custom integrations that talk Modbus (TCP/RTU-over-TCP/serial): pymodbus device_id usage, safe polling/writing, pacing/backoff, encoding multi-register values, cached fallback, and translation-backed entities.
Testing patterns for Home Assistant custom components—coordinator and entity unit tests, register map coverage, write-path tests, and unique_id/device stability checks.
Home Assistant translation_key and identifier practices—entity/device naming via translations, stable unique IDs, and migration tips.
Diagnostics for Modbus in Home Assistant custom components—framing/extra-data errors, unit_id mismatches, pacing/timeouts, write contention, and logging patterns.
