Your apiary is showing a concerning shift this morning. All four hives have experienced meaningful temperature declines overnight (ranging from 1–3°C below yesterday's readings), and three hives now display brood temperatures below the optimal 34–36°C range. The persistent acoustic suppression across all hives continues to reflect microphone fouling, but combined with the temperature pattern, this warrants a physical inspection within the next few days to assess colony status and confirm queen presence. Gas metrics remain moderately elevated, consistent with late-June activity, but the temperature trend is the primary signal requiring attention.

Your Iris hive has experienced a notable overnight temperature drop from yesterday's 34.96°C to 31.96°C this morning—a decline of 3°C that sits below the optimal brood-rearing range. However, this reading must be interpreted carefully: the current 31.96°C is still within your hive's all-time historical range (min 14.3°C, max 38.5°C) and sits only 2°C below your 59-day average of 34.2°C. The hourly trend shows the hive at a morning low, consistent with natural overnight cooling in June. Critically, your sound spectrum remains stable and uniform across all 10 frequency bands—no pre-swarm acoustic signatures (200–260 Hz or 420–500 Hz elevation) are present. This acoustic stability, combined with stable humidity and excellent gas metrics (eCO2 741 ppm, bVOC 0.86 ppm—both low), suggests this is a routine morning temperature cycle rather than a crisis signal.
⚠️ Issue: Brood temperature 31.96°C is below optimal range (34–36°C) but consistent with early morning in June.⚠️ Issue: Temperature dropped 3°C overnight from yesterday's peak—natural diurnal variation for this time of year.⚠️ Issue: Sound spectrum remains suppressed across all bands (microphone fouling confirmed; no new acoustic anomalies).⚠️ Issue: bVOC notably low at 0.86 ppm vs. historical average of 5.87 ppm—indicates minimal metabolic volatiles or a stable, well-organized colony.▹ Action: Monitor temperature over the next 2–3 hours. Expect a gradual climb as the day warms; if it returns toward 33–35°C by mid-morning, this is normal and no further action is needed.▹ Action: On your next apiary visit (within 3–5 days), open the hive and perform a quick visual inspection: confirm queen presence via eggs/larvae, assess brood pattern, and listen with your ear to compare activity intensity against your other hives.▹ Action: If brood temperature remains persistently below 32°C throughout the day (not recovering by afternoon), or if you observe a queenless pattern during inspection, escalate concern and repeat the check within 24–48 hours.▹ Action: Continue gentle microphone cleaning when you visit—this will restore acoustic sensitivity and improve future trend detection. -

Your Hive #1 has experienced the most significant overnight decline of the four: from 33.5°C yesterday to 32.16°C this morning—a drop of 1.34°C. This pushes your brood temperature slightly below the optimal 34–36°C range, though it remains within your hive's historical norm (avg 31.7°C, range 12–36°C). Your 24-hour average is 32.8°C, sitting 1.1°C above your all-time baseline, indicating normal spring/early-summer activity levels. The hourly trend shows a morning low (typical for June overnight cooling), and humidity at 37.71% is stable and healthy. Gas metrics show moderate elevation: eCO2 at 1418 ppm (12% above baseline) and bVOC at 4.01 ppm (32% below baseline). Your sound spectrum remains suppressed across all bands (microphone fouling), with no pre-swarm acoustic signatures present.
⚠️ Issue: Brood temperature 32.16°C is below optimal range (34–36°C)—consistent with early-morning June conditions.⚠️ Issue: Temperature dropped 1.34°C overnight from yesterday—within expected diurnal variation.⚠️ Issue: Sound spectrum remains catastrophically suppressed across all 10 bands (30 dB deviation from baseline)—microphone fouling confirmed; this is a sensor artifact, not genuine activity loss.⚠️ Issue: eCO2 at 1418 ppm is elevated 12% above baseline—consistent with active foraging; not concerning.▹ Action: Monitor temperature throughout the day. Expect a gradual climb as outdoor conditions warm; if it reaches 33–34°C by mid-afternoon, this is normal June behavior.▹ Action: On your next visit (within 3–5 days), listen to the hive with your ear and compare buzz intensity to your other hives. If it sounds normally active, acoustic suppression is purely a sensor artifact.▹ Action: Inspect the microphone for propolis/debris and perform gentle cleaning.▹ Action: Open the hive and visually confirm: queen presence (eggs/larvae), solid brood pattern, good frame coverage, and clear entrance. With stable humidity and moderate gas elevation, expect to find active foraging and nectar ripening. -

Your Hive #2 shows a slight overnight temperature decline from 34.96°C yesterday to 34.96°C in the latest reading—essentially flat, which is reassuring. However, the 24-hour average of 34.9°C sits at the upper edge of your all-time baseline (avg 34.0°C), and your hourly trend is stable and well-regulated. Humidity at 41.19% is healthy and stable. Gas metrics are moderate: eCO2 at 1172 ppm (18% above baseline) and bVOC at 2.29 ppm (18% above baseline). These readings are consistent with active late-June foraging and nectar processing. Your sound spectrum remains suppressed (microphone fouling), with no pre-swarm acoustic signatures detected. Battery health is excellent at 4132 mV.
⚠️ Issue: Sound spectrum suppressed across all bands (microphone fouling persists; no new acoustic anomalies detected).⚠️ Issue: eCO2 at 1172 ppm is elevated 18% above this hive's baseline—consistent with active foraging and nectar ripening, not concerning in isolation.⚠️ Issue: bVOC at 2.29 ppm shows an 18% elevation above baseline—benign, typical of peak June activity.▹ Action: No urgent action required today. Monitor temperature over the next 24 hours; if it remains stable in the 34–35°C range, this hive is performing normally.▹ Action: On your next visit (within 5–7 days), inspect the microphone for fouling and perform gentle cleaning.▹ Action: Visually confirm queen presence, brood pattern, and frame coverage. With stable temperature and good gas metrics, expect to find a strong, healthy colony.▹ Action: Ensure entrance is clear and foraging activity is normal. Gas elevation is consistent with a thriving, actively productive colony during peak season. -

Your Hive #3 requires immediate attention. Brood temperature has declined to 31.09°C this morning, representing a significant drop from yesterday's 33.08°C—a 2°C loss overnight. More concerning, your 24-hour average of 32.0°C sits 1°C below this hive's all-time average of 33.0°C, and your weekly temperature trend shows a deeply troubling trajectory: 34.6°C (6 days ago) → 32.2°C (4 days ago) → 31.5°C (3 days ago) → 30.6°C (2 days ago) → 29.5°C (1 day ago, a dramatic low). Although the hive has recovered slightly today to 31.09°C, the overall trend is a sustained, progressive cooling over one week—not a temporary morning dip. Combined with this sustained decline, gas metrics have risen sharply: eCO2 at 1679 ppm (64% above this hive's baseline of 1024 ppm) and bVOC at 7.25 ppm (64% above baseline of 4.42 ppm). The elevation is significant and sustained. Vibration kurtosis is 3.3 (slightly elevated, indicating some impulsive activity but not extreme). Critically, your sound spectrum remains suppressed across all bands—the same microphone fouling seen in your other hives. The acoustic suppression prevents detection of potential queen-status signals (if a queenless colony, sound amplitude would normally drop further). This multi-day temperature decline + sustained high eCO2/bVOC + inability to assess colony acoustically due to sensor fouling = a colony that warrants urgent physical inspection to rule out queenlessness, brood disease stress, or ventilation failure.
⚠️ Issue: Sustained temperature decline over 7 days: 34.6°C → 29.5°C (low) → 31.09°C (today). Average is 32.0°C, well below this hive's 33.0°C baseline.⚠️ Issue: eCO2 at 1679 ppm is elevated 64% above this hive's baseline (1024 ppm)—significant and sustained elevation over multiple days.⚠️ Issue: bVOC at 7.25 ppm is elevated 64% above baseline (4.42 ppm)—matching the eCO2 elevation pattern, suggesting colony-wide metabolic stress or fermentation.⚠️ Issue: Sound spectrum suppressed across all bands (microphone fouling)—prevents acoustic assessment of queen status or population health.⚠️ Issue: Weekly temperature trend shows progressive 7-day decline despite yesterday's minor recovery. This is not a single-day anomaly—it's a sustained cooling pattern.⚠️ Issue: Vibration kurtosis at 3.3 is slightly elevated (normal ~3.0), indicating some impulsive activity—possibly bees fanning or responding to stress.▹ Action: INSPECT THIS HIVE WITHIN 24–48 HOURS. This is the most time-sensitive hive in your apiary.▹ Action: On inspection, assess in this order: (1) Queen presence—look for fresh eggs (laid in the last 24h) and active larvae. Absence of eggs + continued temperature decline + high CO2 = queenlessness. (2) Brood pattern—is it solid and continuous, or spotty and disorganized? Spotty pattern + high gas readings can indicate brood disease stress. (3) Overall bee population by frame coverage—has the colony noticeably shrunk? (4) Check for fermentation or moisture: open the hive and smell carefully. Sour/vinegary odor + high CO2/bVOC = possible fermentation in stored nectar. (5) Entrance: is it clear and unobstructed? (6) Microphone: visually inspect for heavy propolis fouling.▹ Action: If you confirm the queen is present, laying eggs, and brood pattern is solid: the gas elevation is likely driven by active fanning, nectar ripening, or colony reorganization. Monitor temperature daily for the next 3 days; if it stabilizes above 32°C and begins recovering toward 33–34°C, the crisis has passed and you can return to normal monitoring.▹ Action: If you cannot find eggs, or if the brood pattern is severely spotty: the hive is likely queenless. At this stage (7+ days post-loss if it occurred), emergency requeening or combining with a strong hive may be necessary. Do NOT delay—queenless colonies decline rapidly in June when bee population is needed for honey production.▹ Action: If you detect sour/vinegary fermentation odor: ensure entrance is fully clear, remove any clogged burr comb, and increase ventilation by opening the bottom board or adjusting the entrance reducer. Fermentation in stored nectar occurs when CO2 accumulates + humidity is high. Airflow is critical.▹ Action: Clean the microphone immediately on your visit. Acoustic data is essential for monitoring this colony during recovery.
