Proposed change

Support for Matter EVSE - EnergyEvse cluster

Matter 1.3’s energy features also enable new energy-centric devices, the first of which is Electric Vehicle Supply Equipment (EVSE). This enables EV charging equipment manufacturers to present a consumer-friendly way to control how and when they charge their vehicles. It features the ability to manually start or stop charging, adjust the charging rate, or specify how many miles of range to be added by a set departure time, leaving the charging station to automatically optimize the charging to happen at the cheapest and lowest carbon times.

As discussed with Marcel, the second step would be to create a specific entity for EVSE in Home Assistant for better integration.

Supported attributes:

  • EnergyEvse.Attributes.State
  • EnergyEvse.Attributes.SupplyState
  • EnergyEvse.Attributes.FaultState
  • EnergyEvse.Attributes.CircuitCapacity
  • EnergyEvse.Attributes.MinimumChargeCurrent
  • EnergyEvse.Attributes.MaximumChargeCurrent
  • EnergyEvse.Attributes.UserMaximumChargeCurrent

Add command_timeout attribute in MatterButtonEntityDescription class. This is mandatory for EnergyEvse commands.

Type of change

  • Dependency upgrade
  • Bugfix (non-breaking change which fixes an issue)
  • New integration (thank you!)
  • New feature (which adds functionality to an existing integration)
  • Deprecation (breaking change to happen in the future)
  • Breaking change (fix/feature causing existing functionality to break)
  • Code quality improvements to existing code or addition of tests

All lights are green. Tests are now successful.
I had to close the #133457 because I have conflicts with the branch/PR and I was not able to fix it.
