v0.5.0

Frequenz Microgrid API Client Release Notes

Upgrading

• This release stops using betterproto and grpclib as backend for gRPC and goes back to using Google's grpcio and protobuf.

  If your code was using betterproto and grpclib, it now needs to be ported to use grpcio and protobuf too. Remember to also remove any betterproto and grpclib dependencies from your project.

• We are now using base-client v0.6.0.

v0.4.0

Frequenz Microgrid API Client Release Notes

Summary

This release migrates to use betterproto and grpclib instead of grpcio and protobuf internally. It also stops leaking these internal libraries to downstream users. It should now be possible to use the client without having to use grpclib or betterproto directly.

Upgrading

• The client now uses a string URL to connect to the server, the grpc_channel and target arguments are now replaced by server_url. The current accepted format is grpc://hostname[:<port:int=9090>][?ssl=<ssl:bool=false>], meaning that the port and ssl are optional and default to 9090 and false respectively. You will have to adapt the way you connect to the server in your code.

• The client is now using grpclib to connect to the server instead of grpcio. You might need to adapt your code if you are using grpcio directly.

• The client now doesn't raise grpc.aio.RpcError exceptions anymore. Instead, it raises its own exceptions, one per gRPC error status code, all inheriting from GrpcError, which in turn inherits from ClientError (as any other exception raised by this library in the future). GrpcErrors have the grpclib.GRPCError as their __cause__. You might need to adapt your error handling code to catch these specific exceptions instead of grpc.aio.RpcError.

  You can also access the underlying grpclib.GRPCError using the grpc_error attribute for GrpStatusError exceptions, but it is discouraged because it makes downstream projects dependant on grpclib too

• The client now uses protobuf/grpc bindings generated betterproto (frequenz-microgrid-betterproto) instead of grpcio (frequenz-api-microgrid). If you were using the bindings directly, you might need to do some minor adjustments to your code.

• If an unknown EV charger component state is received, it will now be set to EVChargerComponentState.UNKNOWN instead of EVChargerComponentState.UNSPECIFIED.

New Features

• The client now raises more specific exceptions based on the gRPC status code, so you can more easily handle different types of errors.

  For example:

  try:
     connections = await client.connections()
  except OperationTimedOut:
     ...

  instead of:

  try:
     connections = await client.connections()
  except grpc.aio.RpcError as e:
     if e.code() == grpc.StatusCode.DEADLINE_EXCEEDED:
        ...

• We now expose component errors as part of the streamed component data:

  • BatteryData.errors
  • InverterData.errors

• We now expose component states as part of the streamed component data:

  • BatteryData.component_state and BatteryData.relay_state
  • InverterData.component_state

• Added the missing EVChargerComponentState.UNKNOWN state.

Bug Fixes

• Fix a leakage of GrpcStreamBroadcaster instances.
• The user-passed retry strategy was not properly used by the data streaming methods.
• The client set_bounds() method might have not done anything and if it did, errors were not properly raised.

What's Changed

• Clear release notes by @llucax in #32
• Bump nox from 2023.4.22 to 2024.3.2 by @dependabot in #35
• Update protobuf requirement from <5,>=4.21.6 to >=4.21.6,<6 by @dependabot in #34

v0.1.2

Frequenz Microgrid API Client Release Notes

Summary

This version downgrades the protobuf dependency to 4.21.6.

This is the version used in the SDK v1.0.0-rc5, which we imported the code from. If we don't do this we introduce an unnecessary dependency conflict with the SDK.

Summary

This release add some symbols that were missing from the public API:

• ComponentCategory
• ComponentMetadata
• ComponentMetricId
• ComponentType
• Fuse
• GridMetadata
• InverterType

What's Changed

• Clear release notes by @llucax in #21
• Expose missing symbols by @llucax in #22

Full Changelog: v0.1.0...v0.1.1

v0.1.0

Frequenz Microgrid API Client Release Notes

Summary

Code import from the SDK v1.0.0-rc5 release.

Upgrading

Changes compared to the code in the SDK v1.0.0-rc5 release:

• The MicrogridGrpcClient class was renamed to ApiClient.

  • The retry_spec constructor argument was renamed to retry_strategy.

• The MicrogridApiClient abstract base class was removed, use ApiClient instead.

• The Connection class is now a dataclass instead of a NamedTuple. If you use the tuple-like interface (connection[0], etc.) you should use the named attributes instead or use dataclasses.astuple() to convert it to a tuple.
