Your apiary is in late spring with warm outdoor conditions (26.7°C, very dry at 7.3% RH). Three of your four hives show healthy brood temperatures and normal activity patterns, but Hive #3 is significantly cooler at 30.45°C—well below the optimal 34–36°C range—suggesting either a smaller population, early brood pause, or possible queen issue. Additionally, Hive #2 shows elevated bVOC (6.03 ppm) and eCO2 (1598 ppm) with low humidity (44.3%), warranting inspection for early disease or ventilation stress.

node_2662 healthy Score: 82/100📋 Overall Health
Your Iris hive is performing well. Brood temperature is steady at 34.6°C (ideal range), humidity is optimal at 59.9%, and gas metrics are excellent (IAQ 50, eCO2 542 ppm, bVOC 0.55 ppm). Sound spectrum shows balanced energy across all frequency bands with no concerning peaks, and vibration patterns are calm and uniform—classic signs of a contented, queen-right colony actively managing brood.
▹ Action: Continue routine monitoring. No immediate action needed.▹ Action: Watch Iris's sound spectrum over the next 7 days; if 420–500 Hz energy begins to rise, it could signal early pre-swarm queen piping—document and prepare for swarm management. -

Your Hive #1 is thriving. Brood temperature at 34.27°C is in the middle of the optimal range with minimal daily variance (33.9–34.3°C). Humidity at 39.4% is on the dry side but not dangerous. Gas metrics are normal (IAQ 116, eCO2 1351 ppm, bVOC 3.44 ppm—moderate but acceptable for May). Sound and vibration spectra are flat and balanced, indicating steady, quiet colony work. Tilt is stable at 4° (excellent hive orientation).
▹ Action: Maintain current management. This hive shows textbook healthy brood-rearing behavior.▹ Action: The 350–420 Hz band carries slightly elevated energy (0.529); this is within normal range but consistent with active worker communication—compatible with healthy spring buildup.▹ Action: Continue weekly monitoring; no urgent inspection needed unless issues arise in paired hives. -
node_34225 warning Score: 58/100📋 Overall Health
Your Hive #2 is maintaining good brood temperature (34.63°C) and normal vibration behavior, but shows concerning gas and humidity anomalies: bVOC is elevated at 6.03 ppm (3× baseline), eCO2 is 1598 ppm (3× typical), and humidity has dropped to 44.3% (well below the 50–70% optimum for brood). This pattern can indicate early disease onset (fermentation, Nosema) or aggressive ventilation response to colony stress. The elevated 500–600 Hz sound band (0.537) is also slightly elevated vs. other hives—worth monitoring.
⚠️ Issue: Elevated bVOC (6.03 ppm) and eCO2 (1598 ppm) suggest possible fermentation, early Nosema infection, or ventilation blockage.⚠️ Issue: Low humidity (44.3%) increases desiccation risk to larvae and may correlate with disease stress.⚠️ Issue: Slight elevation in 500–600 Hz sound band could indicate distressed fanning or colony unease.▹ Action: Perform a full internal inspection THIS WEEK: check for visible signs of American Foulbrood (sunken/punctured cappings, ropy brood), Nosema (dysentery spots on frames/entrance), or fermentation (wet, pungent smell).▹ Action: Confirm entrance and top ventilation are clear. If blocked, clean gently to restore airflow.▹ Action: Monitor bVOC and humidity daily. If bVOC rises above 8 ppm or humidity continues dropping, suspect disease and consider sampling for lab analysis.▹ Action: In the short term, ensure adequate ventilation and avoid feeding sugar water unless colony is genuinely short on stores—fermentation risk is already elevated. -
node_547 critical Score: 35/100📋 Overall Health
Your Hive #3 is in distress. Brood temperature at 30.45°C is dangerously low—4–6°C below the optimal 34–36°C—indicating either a queen absence, severe population collapse, or early abandonment. Over 24 hours, temperature ranged 30.4–33.3°C (avg 32.3°C), showing the colony struggling to maintain brood warmth. While humidity is higher than other hives (64.1%, possibly compensating), gas metrics are relatively normal, suggesting the issue is population-related, not disease. The latest sound spectrum shows elevated low-frequency energy (100–150 Hz at 0.573), consistent with a weakened or queenless colony trying to organize. Vibration kurtosis is elevated (3.1), suggesting irregular, stressed activity patterns.
⚠️ Issue: Critical brood temperature deficit: 30.45°C is 4–6°C below optimal, indicating queenlessness or severe population collapse.⚠️ Issue: Temperature persistence problem: sustained low brood temperature over 24h shows colony cannot recover thermoregulation.⚠️ Issue: Elevated low-frequency sound (100–150 Hz) and irregular vibration kurtosis (3.1) indicate disorganized colony behavior typical of queenless hives.⚠️ Issue: No queen-presence signal (300–500 Hz structured energy) visible in the acoustic spectrum.▹ Action: INSPECT THIS HIVE IMMEDIATELY: Open the brood nest and check for the presence of a live queen. Look for fresh eggs (laid in last 24–48h) in a pattern; absence = queenless.▹ Action: If queenless, check for emergency queen cells (vertical, off comb edge, made from worker brood). If found, the colony may recover; if none and temperature is still <32°C, consider this a dead loss.▹ Action: If queen is present but colony is very weak, assess disease: check for dysentery, mold, or foul smell. Nosema or chalkbrood in small populations will cause rapid collapse.▹ Action: If colony is salvageable (live queen + brood), consider combining with a strong hive or requeening with a mated queen.▹ Action: If the colony is effectively dead, remove hive from apiary to prevent robbing and disease spread. Disinfect equipment before reuse.
