TTM4HVAC — source-all train (TsFile)

Apache TsFile version of gft/ttm4hvac-source-all-train.

Overview

HVAC and weather time-series data used to train the source-all TinyTimeMixer model (gft/ttm4hvac), the main model of the TTM4HVAC project. This split aggregates all available source-building data under default and non-default control conditions. Each series_id is a building/sensor series of time-aligned weather and HVAC measurements.

Schema (TsFile structure)

Time (INT64, milliseconds) — the observation timestamp.
series_id (TAG) — device dimension identifying the building/sensor series.
Room_Air_Temperature_C / Outdoor_Air_Temperature_C (FIELD, FLOAT).
Heating_Setpoint_C / Cooling_Setpoint_C (FIELD, FLOAT).
Outdoor_Humidity (FIELD, FLOAT).
Wind_Speed_m_s (FIELD, FLOAT).
Direct_Solar_Radiation_W_m_2 (FIELD, FLOAT).
HVAC_Power_Consumption_W (FIELD, FLOAT).
is_default (FIELD, FLOAT) — whether the sample is under a default control schedule.

Usage

Install the Apache TsFile Python SDK (pip install tsfile) and read a converted file:

from pathlib import Path
from tsfile import TsFileReader

path = Path("ttm4hvac_source_all_train.tsfile")
with TsFileReader(str(path)) as reader:
    schemas = reader.get_all_table_schemas()
    print("tables:", list(schemas))
    table_name = next(iter(schemas))
    table = schemas[table_name]
    columns = [column.get_column_name() for column in table.get_columns()]
    print("columns:", columns)
    field_names = [
        column.get_column_name()
        for column in table.get_columns()
        if column.get_column_name() not in {"Time", "time"}
    ]
    if field_names:
        with reader.query_table(table_name, field_names[:3], batch_size=1024) as result:
            batch = result.read_arrow_batch()
            if batch is not None:
                print(batch.to_pandas().head())
