Stove Use Monitors (SUMs) are sensors that track cooking events to verify actual stove usage and prevent stove stacking. A cooking event is recorded when the stove temperature exceeds a defined threshold, providing continuous, objective data about usage patterns.

​
Key Features

Complete Coverage

Installation required on all active cookstoves unless deviation is justified

Continuous Monitoring

Ongoing measurements with no interruption preferred

Stacking Detection

Track concurrent usage across multiple stoves to prevent double-counting

Data Reliability

Regular collection to prevent data loss when digital transmission isn’t possible

​
Handling Stove Stacking

from emerging import HouseholdAnalytics

# Analyze stove usage patterns
analytics = HouseholdAnalytics("did:ixo:household/123")

stacking_report = analytics.detect_stacking(
    period_start="2024-02-01",
    period_end="2024-02-28",
    stove_types=["traditional", "improved"]
)

# Get detailed cooking events
events = analytics.get_cooking_events(
    min_duration=1800,  # 30 minutes
    min_temperature=60
)

​
Integration with Household Monitoring

from emerging import Household, Device

# Get household digital twin
household = Household.get("did:ixo:household/123")

# Register SUMs for all stoves
for stove in household.stoves:
    sum_device = Device.create(
        type="StoveUseMonitor",
        stove_id=stove.id,
        household_id=household.id
    )
    
    # Link to household digital twin
    household.add_device(sum_device)

# Monitor stove usage compliance
compliance = household.check_monitoring_compliance()
