Curve Control Data Collection

A Home Assistant integration that collects HVAC sensor data for thermal learning and optimization.

Features

• 5-minute sensor collection: Indoor temperature, humidity, HVAC state, and target temperature
• Daily thermal rate calculation: Heating, cooling, and natural drift rates calculated from your HVAC data
• Privacy-focused: Uses anonymous IDs, no personal information collected
• Lightweight: Simple data collection with minimal impact on Home Assistant performance

Installation

HACS (Recommended)

1. Open HACS in Home Assistant
2. Go to "Integrations"
3. Click the "+" button
4. Search for "Curve Control Data Collection"
5. Click "Install"
6. Restart Home Assistant

Manual Installation

1. Download the latest release
2. Copy custom_components/curve_control_data to your Home Assistant custom_components directory
3. Restart Home Assistant

Configuration

1. Go to Settings → Devices & Services
2. Click "Add Integration"
3. Search for "Curve Control Data Collection"
4. Configure the required entities:
   • Temperature Entity: Sensor that reports current indoor temperature
   • HVAC Entity: Climate entity that shows HVAC action (heating/cooling/off)
   • Thermostat Entity: Climate entity for target temperature
   • Humidity Entity (optional): Indoor humidity sensor
   • Weather Entity (optional): Weather integration for forecasts

How It Works

1. Data Collection: Every 5 minutes, collects current temperature, humidity, HVAC state, and target temperature
2. Batching: Sends data in 1-hour batches to minimize network requests
3. Daily Processing: At midnight, sends daily summary and receives calculated thermal rates
4. Thermal Learning: Creates Home Assistant sensors with calculated rates:
   • sensor.curve_control_heating_rate - °F/hour heating rate
   • sensor.curve_control_cooling_rate - °F/hour cooling rate
   • sensor.curve_control_natural_rate - °F/hour natural drift rate

Privacy

• Uses anonymous UUIDs - no personal information collected
• Only HVAC performance data is transmitted
• Data is used solely for thermal learning calculations
• No user identification or location tracking

Thermal Rate Sensors

The integration creates sensors that can be used by other automations:

# Example automation using thermal rates
automation:
  - alias: "Optimize heating based on learned rates"
    trigger:
      platform: state
      entity_id: sensor.curve_control_heating_rate
    action:
      service: climate.set_temperature
      data:
        temperature: "{{ (states('sensor.target_temp') | float) + (states('sensor.curve_control_heating_rate') | float * 0.1) }}"

Troubleshooting

• No thermal rates calculated: Ensure HVAC system runs regularly and check logs for data collection
• Integration won't load: Verify all required entities exist and are accessible
• Data not sending: Check internet connectivity and backend service status
