Your apiary is showing mixed signals as you head into peak spring activity. Three hives are operating within healthy ranges, but Hive #3 is running cooler than ideal (32.6°C), and Hive #2 is showing elevated gas levels (eCO2 1449 ppm, bVOC 4.3 ppm) that warrant closer inspection. The outdoor conditions are cool (15°C) with very low humidity (11%), so ensure your hives have adequate ventilation and monitor for any signs of moisture or disease.

node_2662 healthy Score: 82/100📋 Overall Health
Your Iris hive is performing excellently with stable brood temperature at 34.2°C—right in the sweet spot for active spring brood rearing. Humidity is holding steady at 55%, and gas metrics are excellent (IAQ 54, eCO2 743 ppm, bVOC 0.86 ppm), indicating good ventilation and no signs of disease or fermentation. The acoustic and vibrational signatures show a quiet, well-organized colony with a gentle baseline hum.
▹ Action: No immediate action needed. Continue routine monitoring.▹ Action: With outdoor temps at 15°C, ensure entrance is clear for foragers returning to the hive.▹ Action: Watch for the next 7-10 days for any acoustic energy shift toward 200-260 Hz or 420-500 Hz, which could signal early pre-swarm activity in May. -

Your Hive #1 is in solid shape with excellent brood temperature control at 34.1°C and healthy humidity at 43%. Gas levels are good (IAQ 105, eCO2 1182 ppm, bVOC 2.35 ppm), and the acoustic profile shows a well-balanced frequency signature with some energy in the 350-420 Hz and 420-500 Hz bands, consistent with normal spring activity and possibly early waggle dance behavior. Vibration spectrum is flat and healthy.
▹ Action: Continue monitoring. This hive is performing well and ready for spring expansion.▹ Action: Watch for any spike in the 420-500 Hz acoustic band over the next week—this could indicate queen piping or early pre-swarm signaling.▹ Action: Consider a light inspection in the next 3-5 days to assess brood coverage and food stores, especially given the cooler outdoor temps (15°C) and potential for foraging delays. -

Your Hive #2 is maintaining proper brood temperature (34.7°C) but is showing concerning gas chemistry: eCO2 at 1449 ppm (nearly double your outdoor baseline of 2869 ppm is not anomalous, but the spike is notable) and bVOC at 4.3 ppm—approaching the disease threshold of >5 ppm. The humidity is unusually low at 40%, which combined with elevated bVOC suggests possible early fermentation or moisture stress. The sound spectrum shows elevated energy in the 200-260 Hz swarming indicator band (0.580) and 260-350 Hz fundamental band (0.569), worth monitoring.
⚠️ Issue: Elevated bVOC (4.3 ppm) approaching disease threshold—possible early fermentation or Nosema activity.⚠️ Issue: eCO2 moderately elevated (1449 ppm) suggesting reduced ventilation or higher metabolic activity.⚠️ Issue: Humidity critically low (40%) for spring brood rearing—risk of larval desiccation.⚠️ Issue: Sound spectrum shows elevated 200-260 Hz energy, which could indicate either swarming preparation or colony stress.▹ Action: Inspect this hive within the next 2 days: check for signs of fermented honey, mold, or Nosema symptoms (dysentery, lethargy). Look for queen presence and brood pattern.▹ Action: Ensure entrance is not blocked and top ventilation is adequate. With outdoor humidity at 11%, your hive's low humidity may be due to over-ventilation—consider reducing upper entrance slightly if the colony is small.▹ Action: Monitor bVOC daily. If it climbs above 5.0 ppm or eCO2 rises further, escalate to immediate inspection.▹ Action: Do NOT harvest from this hive until you've ruled out fermentation or disease. -
node_547 warning Score: 68/100📋 Overall Health
Your Hive #3 is running cooler than ideal at 32.6°C—nearly 1.5°C below the optimal 34°C target for active spring brood rearing. This suggests either a smaller population, reduced brood coverage, or early signs of queen decline. The gas chemistry mirrors Hive #2: bVOC at 4.62 ppm (high) and eCO2 at 1480 ppm, indicating possible ventilation stress or early fermentation. The acoustic signature shows unusual energy spikes in the 100-150 Hz (0.608) and 150-200 Hz (0.647) bands—well above baseline—which may indicate a struggling or unusual colony state.
⚠️ Issue: Brood temperature low (32.6°C) for spring—below optimal 34-36°C range, suggesting reduced metabolic activity or smaller population.⚠️ Issue: Elevated bVOC (4.62 ppm) and eCO2 (1480 ppm) mirror concerns in Hive #2—possible fermentation, moisture issues, or disease.⚠️ Issue: Unusual acoustic profile: energy concentrated in 100-150 Hz and 150-200 Hz (baseline hum bands) suggests either a small colony or stressed/disorganized hive state.⚠️ Issue: Vibration profile is elevated across all bands (0.52–0.57 g), higher than the other hives, indicating either more physical activity or possible disturbance.▹ Action: Inspect this hive immediately. Assess colony strength, brood pattern, queen presence, and food stores. Check for signs of disease, fermentation, or small population.▹ Action: If population is small or queen is absent/failing, consider combining with another hive or requeening after a full inspection.▹ Action: Check for moisture condensation or mold inside, especially given the low outdoor humidity and the hive's reduced thermal mass.▹ Action: Monitor bVOC and eCO2 daily. If bVOC exceeds 5.0 ppm, treat as a disease risk and increase monitoring frequency.▹ Action: Verify the tilt sensor (currently 4°) is accurate—any ground settling could explain thermal changes.
