Overview

The TempHistory module is responsible for tracking and managing temperature data over time. It provides telemetry data, processes incoming telemetry, and serves historical temperature data through web routes.

Features

• Tracks hourly, daily, and monthly temperature data.
• Provides telemetry data such as min, max, and average temperatures.
• Stores and retrieves historical temperature data from disk.
• Serves temperature history details via web routes.

UI Hardware / Pinout Configuration

No specific hardware or pinout configuration is required for this module.

Telemetry Provided

The module provides the following telemetry data:

• tempmin: Minimum temperature recorded in the current hour.
• tempmax: Maximum temperature recorded in the current hour.
• tempavg: Average temperature recorded in the current hour.
• tempcount: Number of temperature readings in the current hour.
• daymin: Minimum temperature recorded in the current day.
• daymax: Maximum temperature recorded in the current day.
• dayavg: Average temperature recorded in the current day.
• daycount: Number of temperature readings in the current day.

Telemetry Consumed

The module processes telemetry data with the following fields:

• time: ISO 8601 formatted timestamp of the telemetry data.
• tempReadAt: Timestamp of the last temperature reading.
• temperature*: Temperature readings (e.g., temperature1, temperature2).

Commands Provided

The module does not provide any commands.

Commands Consumed

Additional Information

• Routes:
  The module provides the following web routes:

  • /temphistory: Serves the main temperature history page.
  • /temphistorydetailtoday: Provides detailed temperature data for the current day.
  • /temphistorydetailyesterday: Provides detailed temperature data for the previous day.
  • /temphistorydetailmonth: Provides detailed temperature data for the current month.

• Data Storage:
  The module saves historical temperature data to a file named temphistory.json and loads it on startup.

• Dependencies:

  • Requires the datetime module for processing timestamps. If not available, it attempts to install it using WiFi.
  • Uses ujson for JSON serialization and deserialization.
