Class Method Summary

• .encode_invoke_response(response : InteractionModel::InvokeResponse) : Bytes

  Encode InvokeResponse manually to preserve PATH container types

• .encode_read_response(response : InteractionModel::ReadResponse) : Bytes

  Encode ReadResponse manually to preserve PATH container types TLV::Serializable loses container type metadata, so we build manually

• .invoke_commands(invoke_requests : Array(InteractionModel::CommandDataIB), clusters : Hash(Tuple(UInt16, UInt32), Cluster::Base), session_id : UInt64 | Nil = nil) : InteractionModel::InvokeResponse

  Execute commands from invoke requests

• .parse_invoke_request(payload : Bytes) : InteractionModel::InvokeRequest | Nil

  Parse InvokeRequest from decrypted TLV payload

• .parse_read_request(payload : Bytes) : InteractionModel::ReadRequest | Nil

  Parse ReadRequest from decrypted TLV payload

• .read_attributes(attribute_requests : Array(InteractionModel::AttributePath), clusters : Hash(Tuple(UInt16, UInt32), Cluster::Base)) : InteractionModel::ReadResponse

  Read attributes from clusters
