Your apiary shows a persistent and now-crystallized acoustic anomaly: all four hives continue to exhibit dramatically suppressed sound spectra, but the pattern remains stable day-to-day and is NOT worsening. Brood temperatures are healthy and stable across all hives, gas metrics are reasonable for June, and all structural indicators (tilt, vibration, battery) are normal. The consistency and lack of progression over 48 hours strongly indicates a sensor or environmental factor (likely microphone fouling or propolis buildup) rather than a genuine colony health crisis. However, Hive #3 shows a new concerning development: brood temperature has dropped to 33.35°C and is trending downward from yesterday's 32.86°C baseline—this warrants investigation this week.

Your Iris hive continues to excel. Brood temperature at 34.21°C is perfectly in the optimal 34–36°C range and remains consistent with this hive's 56-day historical average of 34.2°C. Humidity at 47.73% is stable and healthy. Gas metrics are exemplary: eCO2 at 796 ppm (well below baseline of 788 ppm—actually slightly lower than normal, which is fine for June) and bVOC at 0.97 ppm (notably LOW compared to this hive's average of 6.13 ppm, indicating minimal volatile production and healthy stable conditions). Battery is strong at 4076 mV with excellent 24h stability. The acoustic spectrum remains suppressed across all bands, but this is consistent and stable—NOT worsening.
⚠️ Issue: Sound spectrum suppressed 5–15 dB below historical baseline across all 10 frequency bands. The 350–420 Hz band is the most affected (−14.6 dB). This pattern is identical to yesterday and has NOT degraded, suggesting microphone fouling rather than genuine activity loss.⚠️ Issue: Vibration profile shows slight upward trending in the second half of the 24h period (+0.6–0.9 dB in low-frequency bands 5–80 Hz), which is benign and consistent with normal diurnal activity cycling.▹ Action: On your next apiary visit (within 7–10 days), visually inspect the sensor microphone location for propolis, wax debris, or dust. Even light accumulation can dramatically attenuate sound transmission.▹ Action: When you visit, listen to your Iris hive with your ear. If it sounds normally active and buzzing, the acoustic suppression is almost certainly a microphone fouling issue. If it sounds quiet, note population density and check brood pattern.▹ Action: If fouling is confirmed, gentle propolis removal with a wooden stick (never metal tools) may restore acoustic sensitivity.▹ Action: Continue routine weekly monitoring. All core health indicators (temperature, humidity, gas, vibration, battery) are excellent and this hive is performing at the top of your apiary. -

Your Hive #1 shows stable brood temperature at 33.81°C (24h range 32.9–34.2°C, avg 33.7°C), which is above this hive's historical average of 31.7°C by +2.0°C—warm but still within normal operating limits. However, gas metrics are notably elevated: eCO2 1598 ppm (vs. baseline 1267 ppm, +26% above normal) and bVOC 6.04 ppm (vs. baseline 5.88 ppm, +3% above normal). These elevations suggest active brood rearing or nectar ripening, which is typical for June. The critical issue remains the acoustic spectrum: catastrophically suppressed across all bands (−5 to −30 dB below baseline), matching yesterday's severe suppression pattern. This hive continues to show the most severe acoustic anomaly in your apiary.
⚠️ Issue: Acoustic spectrum devastatingly suppressed: all 10 frequency bands are 5–31 dB below historical baseline. The 100–150 Hz band at −30.21 dB represents approximately 1,000× energy reduction from baseline (vs. all-time avg of +0.47 dB). This is the WORST acoustic anomaly recorded for this hive.⚠️ Issue: eCO2 elevated to 1598 ppm (26% above this hive's baseline of 1267 ppm). This elevation is consistent with active brood rearing or nectar ripening—benign explanations—but warrants monitoring to ensure it does NOT spike further over the next 3–5 days.⚠️ Issue: Battery trajectory shows slight draining (−22 mV over 24h), but 4196 mV is well above the critical threshold and healthy. Monitor for any accelerating drain pattern.⚠️ Issue: Outdoor conditions show elevated VOC (bVOC 1.00 ppm vs. clean baseline <0.5 ppm) and high eCO2 (4465.9 ppm vs. typical 400–500 ppm), suggesting regional air quality impacts. This may contribute to your colony's gas readings but does NOT explain the acoustic suppression.▹ Action: Conduct a physical inspection within 3–5 days (this week, not emergency) to determine whether the acoustic suppression reflects a microphone fouling issue or genuine colony activity changes. Key observations: (1) Listen to the hive with your ear—compare activity to your other hives. If it sounds normal, the sensor is fouled. If subdued or quiet, note this. (2) Visually estimate bee population by frame coverage (% of frames with bees). (3) Look for queen presence (eggs and larvae). (4) Inspect the microphone for propolis or debris.▹ Action: If microphone fouling is confirmed, gentle propolis removal should restore acoustic sensitivity.▹ Action: Monitor eCO2 and bVOC over the next 2–3 days: if they drop back toward baseline, the elevation was temporary (weather or foraging activity). If they remain elevated for >5 days AND brood temperature begins to drop 1–2°C below this hive's normal 33–34°C range, escalate to a closer inspection for possible ventilation blockage or fermentation.▹ Action: Ensure the entrance is clear and unobstructed to allow free airflow and normal ventilation.▹ Action: Do NOT apply treatments or make drastic changes based on sensor data alone. Ground truth from physical inspection is essential before any hive intervention. -

Your Hive #2 is performing solidly. Brood temperature at 35.03°C is in the optimal range and consistent with this hive's all-time average of 34.0°C. Humidity at 39.39% matches this hive's historical baseline of 40.0%—dry conditions are normal for this colony. Gas metrics are healthy: eCO2 949 ppm (below baseline of 989 ppm) and bVOC 1.38 ppm (well below baseline of 1.94 ppm), indicating minimal metabolic stress or excess volatiles. Battery is stable at 4048 mV. The acoustic spectrum remains suppressed across all bands, but the pattern is stable and consistent with yesterday—no worsening observed.
⚠️ Issue: Sound spectrum suppressed 10–16 dB below historical baseline across most frequency bands. The 350–420 Hz band shows the largest deviation (−16 dB). This is consistent with yesterday's report and suggests microphone fouling rather than genuine activity changes.⚠️ Issue: Data telemetry is sparse (only 2 readings in last 24h vs. the normal ~260+), which limits trend detection for today. However, the latest reading at 2026-06-22 06:08 UTC shows stable conditions matching yesterday's snapshot.▹ Action: On your next apiary visit (within 7–10 days), inspect the sensor microphone for propolis, wax, or debris accumulation.▹ Action: Listen to this hive with your ear during inspection. If it sounds normally active, the acoustic suppression is a sensor artifact. If it sounds unusually quiet, note population coverage and brood pattern.▹ Action: Ensure your water source is clean and accessible—with outdoor humidity at 9.28%, your bees will be focused on water management and may increase foraging for moisture.▹ Action: Continue routine monitoring. Temperature and gas profiles are excellent. -

Your Hive #3 shows a concerning downward trend today compared to yesterday. Brood temperature at 33.35°C is BELOW this hive's all-time average of 33.0°C (−0.35°C deviation), and more importantly, the hourly trend shows a gradual RISE from a low of 30.2°C overnight to 33.5°C now—suggesting the hive may have experienced a significant cold event or brood cluster repositioning early this morning. Gas metrics are elevated: eCO2 1613 ppm (vs. baseline 1024 ppm, +57% above normal—the HIGHEST eCO2 reading in this hive's 77-day history) and bVOC 6.23 ppm (vs. baseline 4.42 ppm, +41% above normal). Combined with the severe acoustic suppression, this pattern warrants investigation to clarify whether the hive is experiencing fermentation, ventilation stress, or brood cluster migration.
⚠️ Issue: Brood temperature trajectory shows a dramatic LOW point at 30.2°C early this morning, with gradual recovery to 33.5°C now. This 3.3°C swing over 24 hours is significant and suggests either: (a) a brood cluster migration (sensor moved away from the warmed area), or (b) a transient colony stress event (possible swarm preparation or environmental disturbance early morning).⚠️ Issue: eCO2 CRITICALLY ELEVATED at 1613 ppm—the single highest reading recorded for this hive across 77 days of history. This is 57% above this hive's baseline (1024 ppm) and warrants urgent clarification. Elevated CO2 can indicate: nectar ripening (benign), active brood rearing (benign), or fermentation/ventilation blockage (concerning). The combination with the temperature swing and acoustic suppression creates ambiguity.⚠️ Issue: bVOC elevated to 6.23 ppm (41% above baseline), consistent with active colony work—but in context of the eCO2 spike, this may suggest fermentation or increased metabolic stress.⚠️ Issue: Acoustic spectrum remains catastrophically suppressed (−5 to −30 dB below baseline, matching Hive #1's severity). The 100–150 Hz band at −30.5 dB represents ~1,000× energy reduction.⚠️ Issue: Battery trajectory shows slight draining (−36 mV over 24h), but 4086 mV is still healthy. Monitor for acceleration.⚠️ Issue: Weekly temperature trend data shows Hive #3 has been declining for the past ~2 weeks: [34.8°C → 34.8°C → 34.8°C → 34.6°C → 34.5°C → 32.2°C → 31.5°C → 30.6°C → 29.5°C]. This is a SIGNIFICANT DOWNWARD TRAJECTORY that suggests either seasonal cluster contraction (less likely in June) or a genuine problem (brood cluster migration, possible population loss, or queen issues). This is the most concerning hive in your apiary today.▹ Action: Conduct a physical inspection WITHIN 3–5 DAYS THIS WEEK (not emergency, but more urgent than the others) to clarify what has happened to this colony. Key observations: (1) Listen to the hive with your ear—compare activity and buzz intensity to your other hives. (2) Open the hive and visually assess bee population by frame coverage. Are bees present on most frames, or are they clustered in one area? (3) Check for queen presence by looking for eggs and larvae. (4) Inspect brood pattern—is it solid and continuous, or are there gaps suggesting recent population loss? (5) Look for signs of fermentation (discoloration, sour smell, slime on frames—very unlikely in June but worth noting). (6) Inspect the sensor microphone for fouling.▹ Action: If brood cluster migration is suspected (bees present but concentrated away from sensor location): expect temperature to gradually recover toward 33–34°C over 1–3 weeks. Elevated eCO2 is consistent with a reorganizing colony (fanning activity, reduced air circulation near sensor). This is NORMAL spring/early summer behavior—not a crisis. Monitor temperature recovery.▹ Action: If brood cluster migration is NOT found and population appears reduced or queen is absent: this is more serious. Check for: capped queen cells (is a new queen emerging?), signs of recent swarming (missing large population cohort), or disease indicators. Escalate to a follow-up inspection 1–2 weeks later to confirm queen presence or emergence.▹ Action: If the hive sounds quiet to your ear AND population is visibly low AND no queen signs: this warrants urgent reassessment of colony viability. Feeding and monitoring may be needed.▹ Action: IMPORTANT: The eCO2 spike to 1613 ppm is likely explained by either nectar ripening (active fanning concentrates CO2 near the sensor) or fermentation if any comb is degrading. Physical inspection will clarify. Do NOT diagnose disease based on gas readings alone.▹ Action: Ensure entrance is clear and unobstructed to allow maximum air exchange.▹ Action: If this hive has been underperforming or declining for 2 weeks (as the weekly trend suggests), and inspection reveals legitimate concerns (population loss, absent queen, signs of distress), consider whether requeening, feeding, or combining with another hive may be warranted—but only AFTER physical confirmation.
