v2.2.0 Release: Flex schedules and group curtialment support

Functional changes

• Introduced dedicated flex schedule endpoints (/flex/schedules) for group curtailment operations
• Added support for group-level curtailment controls using:
  • groupGridTargetKw
  • addressGridTargetW
  • solarInverterCapacityPercentage
• Mapped flex schedule fields to Amber group schedule fields:
  • group_grid_target_kw
  • grid_target_w
  • powerlimit
• Added inverter-level flex schedule views exposing resulting groupSolarInverterScheduleInterval data and steered watt targets
• Separated flex curtailment schedules from user/home inverter schedules (/schedules) to support distinct operational domains
• Retained user inverter schedules for home control use cases using:
  • powerlimit
  • zeroExport

Purpose

Provides a dedicated curtailment-oriented scheduling model for group operations while maintaining separate user-facing inverter scheduling functionality.

This enables:

• Grid-target-based curtailment operations for operators and flexibility services
• Read-only inverter-level visibility into executed group curtailment actions
• Clear separation between group curtailment logic and user/home inverter controls
• More scalable and future-proof scheduling APIs for curtailment and flexibility use cases

Additional notes

• addressGridTargetW is not equivalent to zeroExport; it represents a watt-based grid target used in curtailment operations
• solarInverterCapacityPercentage is analogous to powerlimit within the flex/group curtailment domain, but does not include the user scheduling concept of zeroExport
