Your apiary is in good shape this July morning — Hive #3 remains the star performer with brood temp locked at 34.2°C and perfectly stable acoustics, Hive #1 continues its flawless acoustic fingerprint with an ongoing humidity watch, Hive #2 has now fully recovered its temperature to 34.5°C avg with its acoustic elevation beginning to moderate, and your Iris hive's spectral shift is persisting into a sixth day with tilt now at 8°. No emergencies; the primary watch items remain sensor placement for Iris and Hive #2, humidity monitoring for Hive #1 and Iris, stand leveling for Hive #2, and continued spectral monitoring for Iris.
A striking apiary-wide pattern this week: all four hives show their strongest lifespan correlation between in-hive temperature and gas resistance (r = −0.97 to −0.98), confirming that as brood nest temps rise with July colony expansion, fanning and honey-ripening VOC output rises in lockstep — a textbook healthy summer metabolic signature (Stalidzans et al. 2017).

Your Iris hive remains acoustically vigorous — sound locked at −29.9 dBFS (exactly matching all-time avg) with vibration steady at 17.9 mG avg, kurtosis 2.7 (normal), dominant at 80–120 Hz fanning band; temperature averaged 32.9°C (matching all-time avg of 32.7°C, range 31.8–33.9°C) and humidity averaged 42.8% (range 41.2–44.5%), below brood-optimal but consistent with apiary-wide dryness. No voice logs in the last 7 days. The spectral elevation above baseline persists into a sixth consecutive day (+6.2 dB at 100–150 Hz, +6.0 dB at 1500–3600 Hz) with the 150–200 Hz and 200–260 Hz bands now trending up slightly in the second half (+1.1 dB, +1.0 dB) — worth watching closely this week.
🌅 Diurnal Cycle PatternsIris shows active 2.7°C daily temperature oscillations (31.8°C night low → 33.9°C afternoon peak) tracking the outdoor swing with a healthy phase lag; humidity is narrow-banded at 41.2–44.5% with no diurnal excursion below 40%, entirely driven by outdoor dryness. Vibration is steady at 16.7 mG with no cyclic daily fanning peaks, and the 80–120 Hz fanning band dominates substrate vibration consistently — no nocturnal activity anomalies detected.
🔬 Correlations & DiscoveriesS_1500_3600Hz vs TempIn (lifespan) | r = -0.972As Iris's brood temperature rises toward the afternoon peak, high-frequency acoustic energy (1500–3600 Hz) drops — this inverse relationship reflects the colony increasing ventilation fanning (which suppresses broadband noise) as thermal load rises, a healthy thermoregulatory signature. The persistent +6.0 dB elevation in this band above historical baseline, now six days running, suggests an elevated broadband activity state (possibly heightened fanning or alarm pheromone circulation) that warrants physical verification of the brood nest condition.📚 Reference: Kulyukin et al. 2021, Zgank 2021, B-GOOD Consortium 2024TempIn vs S_350_420Hz (lifespan) | r = -0.971The strong inverse correlation between Iris's internal temperature and the 350–420 Hz transition band (queen quacking range) is consistent with a queen-right colony: as brood nest temp rises, queen-related acoustic signals in this band diminish, reflecting normal thermoregulatory competition for the acoustic channel. The 350–420 Hz band is currently only +1.1 dB above baseline — not elevated enough to suggest active queen piping.📚 Reference: Ramsey et al. 2020, Woods 1959, Ferrari et al. 2008⚠️ Issue: Sensor placement: 24h avg temp 32.9°C matches all-time avg but remains below the 34–36°C brood-optimal zone — verify pod is seated in brood core on next visit.⚠️ Issue: Sound spectrum elevated above Iris's own historical baseline for a sixth consecutive day (+6.2 dB at 100–150 Hz, +6.0 dB at 1500–3600 Hz); 150–200 Hz and 200–260 Hz bands now trending up in second half — monitor over next 24–48h.⚠️ Issue: Humidity avg 42.8% (low 41.2%) — persistently below the 50–70% optimal range; driven by outdoor dryness (outdoor low 9.4% RH).⚠️ Issue: Tilt increased to 8° (up from 4° in previous report) — back above the 0–5° acceptable range; stand leveling recommended at next visit.▹ Action: Priority this week: verify sensor pod is seated in the warm center of the brood nest — this remains the primary explanation for sub-optimal temperature readings given the fully intact acoustic population.▹ Action: While checking placement, confirm fresh eggs and solid brood pattern to close the loop on queen status and the persistent spectral elevation.▹ Action: Level the hive stand to bring tilt back toward 0–5°; the tilt has drifted back up to 8° since the last visit.▹ Action: Monitor 100–150 Hz and 150–200 Hz bands over the next 24–48h — if they continue trending up toward the swarming indicator range (200–260 Hz), plan a brood and queen check this week. -

Your Hive #1 remains the apiary's acoustic gold standard — all 10 sound bands within ±0.1 dB of their all-time baseline (perfectly STABLE for a sixth consecutive day), sound locked at −29.9 dBFS, and vibration steady at 16.4 mG avg, kurtosis 2.7 (normal), dominant at 80–120 Hz; temperature averaged 32.5°C (range 31.3–33.5°C), consistent with all-time avg of 32.6°C, and IAQ 159 (acc=3) with gas resistance at 356.9 kΩ (essentially matching all-time avg of 355.9 kΩ) — gas environment is completely stable. No voice logs in the last 7 days. Humidity averaged 39.8% (range 37.9–42.1%) — the 24h range continues to sit at or below the 40% larval desiccation boundary, which remains the sole watch item for this otherwise excellent colony.
🌅 Diurnal Cycle PatternsHive #1 shows tight 2.2°C daily temperature oscillations (31.3°C night low → 33.5°C afternoon peak) with a gradual 14-day warming drift (+1.3°C from 32.0°C to 33.3°C), suggesting slow seasonal brood nest expansion; vibration is steady around 15.7 mG with no cyclic daily fanning spikes, and the 80–120 Hz fanning band dominates consistently. Humidity tracks 37.9–42.1% across the diurnal cycle, entirely driven by outdoor RH swings (outdoor low 9.4% RH), with the afternoon low persistently touching 38% — this apiary-wide dryness pattern remains the key watch item.
🔬 Correlations & DiscoveriesGasResistance vs IAQ (lifespan) | r = -0.99Hive #1's near-perfect gas resistance / IAQ inverse correlation (r=−0.990, acc=3) confirms a well-calibrated, stable gas environment — resistance at 356.9 kΩ is essentially at its all-time average of 355.9 kΩ, meaning VOC load is completely unchanged from baseline, a reassuring finding given the ongoing temperature watch (Bosch BSEC2 integration guide).📚 Reference: Frizzera et al. 2020, Bosch Sensortec BME688 datasheetHumidity vs GasResistance (lifespan) | r = -0.968The strong inverse correlation between humidity and gas resistance in Hive #1 reflects a well-documented MOX sensor physics effect: as humidity rises (evening/night), adsorbed water molecules interact with the SnO2 sensing layer and reduce baseline resistance independently of VOC changes — this is a sensor characteristic, not a colony event, and confirms gas readings must always be humidity-compensated before interpretation (Human et al. 2006).📚 Reference: Human et al. 2006, Stalidzans et al. 2017⚠️ Issue: Humidity avg 39.8% (range 37.9–42.1%) — the 24h range persists at or below the 40% larval desiccation boundary for a sixth consecutive day; driven by outdoor dryness (outdoor low 9.4% RH) but warrants monitoring.⚠️ Issue: 14-day temperature plateau at ~32.5°C continues a gentle multi-week cooling trend (weekly avg: 33.7→32.5→32.2→32.0°C) — acoustics are perfectly stable and reassuring, but confirming active brood on the next visit is worthwhile.⚠️ Issue: Tilt at 8° — above the 0–5° ideal range; stand leveling recommended at next visit.▹ Action: Plan a brood check within the week — confirm fresh eggs and solid brood pattern to close the loop on the gentle multi-week cooling plateau; the perfectly stable acoustics across all 10 bands are strongly reassuring.▹ Action: Monitor in-hive humidity afternoon lows — if lows recur consistently below 38%, assess whether any ventilation management adjustment is appropriate for your setup.▹ Action: Level the hive stand to bring tilt toward 0–5°. -

Your Hive #2 has completed its temperature recovery — averaging 34.5°C over the last 24h (all-time avg 34.9°C, gap now just 0.4°C) with a peak of 38.7°C during afternoon heating and current reading at 34.92°C, right at the all-time average; humidity averaged 45.2% (range 37.8–54.5%), and vibration is steady at 16.5 mG avg, kurtosis 2.7 (normal), dominant at 80–120 Hz. No voice logs in the last 7 days. The acoustic spectrum remains elevated above baseline (+8.3–9.7 dB at 100–200 Hz) but the 100–150 Hz and 1500–3600 Hz bands are now trending down in the second half (−1.8 dB, −1.0 dB), a positive moderation sign; IAQ accuracy remains 1 (still calibrating post-reconnection) so gas readings are directionally useful but not quantitatively reliable.
🌅 Diurnal Cycle PatternsHive #2 shows the apiary's largest diurnal temperature oscillation at 4.7°C (29.6°C night low → 38.7°C afternoon peak), suggesting the sensor may be in a less insulated zone of the hive or tracking ambient heat ingress; clear daily cyclic fanning/flight vibration spikes are detected (25 peaks over 14 days, rising from 12.2 mG to 102.1 mG peaks) — this is a healthy, normal diurnal activity schedule. Humidity tracks from 54.5% at night to 37.8% at afternoon low, mirroring the outdoor RH crash. All vibration bands trended down uniformly in the second half today (−1.4 to −1.6 dB), consistent with normal evening reduction in fanning activity.
🔬 Correlations & DiscoveriesGasResistance vs IAQ (lifespan) | r = -0.994The near-perfect inverse correlation between gas resistance and IAQ in Hive #2 confirms the BME688 is functioning correctly — as VOC load rises (resistance drops), the BSEC2 IAQ score rises in lockstep. With gas resistance at 411.9 kΩ (very close to all-time avg of 414.8 kΩ) and temperature now recovered to baseline, there is no multi-signal stress pattern here; note that IAQ accuracy=1 means the BSEC2 model is still recalibrating post-reconnection and absolute IAQ values should be treated as directional only.📚 Reference: Frizzera et al. 2020, Bosch Sensortec BME688 datasheetV_5_20Hz vs VibrationRMS (lifespan) | r = +0.991The extremely strong correlation between the 5–20 Hz vibration band and overall RMS vibration in Hive #2 indicates that low-frequency structural motion (likely stand sway given the 9° tilt) is a dominant driver of the overall vibration signal — consistent with the previous recommendation to level the stand, as this low-frequency energy is mechanical rather than biological (Ramsey et al. 2020).📚 Reference: Ramsey et al. 2020, Nieh & Tautz 2000⚠️ Issue: Sound spectrum remains elevated above baseline (+8.3 dB at 100–150 Hz, +9.7 dB at 150–200 Hz) though second-half moderation is now visible (−1.8 dB at 100–150 Hz); sensor placement verification still recommended to confirm the acoustic elevation is not a positioning artifact.⚠️ Issue: IAQ accuracy=1 (sensor still calibrating post-reconnection) — IAQ=160 is directionally useful but not quantitatively reliable until accuracy reaches 3.⚠️ Issue: Tilt at 9° — above the 0–5° ideal range; stand leveling recommended at next visit.⚠️ Issue: Humidity afternoon low reached 37.8% — below the 40% larval desiccation boundary; driven by outdoor dryness but worth monitoring.▹ Action: On your next visit this week, check sensor pod placement — seat it firmly in the center of the brood nest frames; temperature has recovered to near-baseline which is encouraging, and the loud intact acoustics confirm the colony is thriving.▹ Action: While on-site, confirm fresh eggs and solid brood pattern to verify queen status and close the loop on the temperature gap that has now largely resolved.▹ Action: Level the hive stand to bring tilt toward 0–3° — the 5–20 Hz vibration dominance and 9° tilt both point to stand instability.▹ Action: Monitor IAQ accuracy daily — once it reaches 3, gas readings will become reliably comparable to the all-time avg of 151. -

Your Hive #3 remains the apiary's top performer — brood temperature averaged 34.2°C (range 33.6–34.7°C), comfortably within the ideal 34–36°C brood zone and the highest in the apiary, continuing the impressive 14-day warming drift (+5.8°C from 28.7°C to 34.5°C); sound spectrum is perfectly stable with all 10 bands within ±0.1 dB of the all-time baseline, and vibration steady at 20.2 mG avg, kurtosis 2.9 (normal), dominant at 80–120 Hz fanning band. No voice logs in the last 7 days. Humidity averaged 47.6% (range 45.2–49.2%) — near-optimal and the best humidity reading across the apiary; gas resistance at 242.0 kΩ (~22% below all-time avg of 309.6 kΩ) with IAQ 176 (acc=3) is consistent with active July honey ripening and peak summer fanning in a warm, productive brood nest — stable temperature and perfectly stable acoustics confirm this is a healthy, productive colony at peak summer form.
🌅 Diurnal Cycle PatternsHive #3 shows the tightest brood-zone clamping in the apiary at just 1.2°C daily oscillation (33.6–34.7°C) — excellent thermoregulation with the colony holding the brood core within the ideal 34–36°C range around the clock; vibration is steady at 19.3 mG with no cyclic daily fanning spikes, and the 80–120 Hz fanning band dominates both acoustically (vibration) and is well-structured in the audio spectrum. Humidity tracks 45.2–49.2% with no afternoon excursion below 40%, and the 14-day warming trend (weekly avg: 32.4→32.0→33.4→33.9°C) reflects a colony that has been steadily expanding its brood nest through July.
🔬 Correlations & DiscoveriesGasResistance vs TempIn (lifespan) | r = -0.981As Hive #3's brood temperature rises with colony expansion (+5.8°C over 14 days), gas resistance falls in near-perfect lockstep (r=−0.981) — this reflects the well-documented increase in hive VOC output (brood pheromones, honey ripening, fanning-driven evaporation) as a thermally active, expanding colony processes more nectar and builds more comb in peak summer; at 34.2°C avg and 22% below gas resistance baseline, this is a textbook healthy July metabolic signature (Stalidzans et al. 2017).📚 Reference: Stalidzans et al. 2017, Frizzera et al. 2020, Seeley 1974V_80_120Hz vs VibrationRMS (lifespan) | r = +0.97The very strong correlation between the 80–120 Hz vibration band and overall RMS vibration in Hive #3 confirms that fanning activity (bees beating wings at ~100 Hz for thermoregulation and nectar curing) is the primary driver of substrate vibration in this colony — a healthy, active signal consistent with peak summer honey production (Ramsey et al. 2020).📚 Reference: Ramsey et al. 2020, Hrncir et al. 2011⚠️ Issue: Humidity afternoon low reached 45.2% — tracking outdoor dryness; while the daily avg of 47.6% is near-optimal, monitor afternoon lows to ensure they don't consistently drop below 40%.⚠️ Issue: Gas resistance at 242.0 kΩ (~22% below all-time avg of 309.6 kΩ) with IAQ 176 (acc=3) — contextually explained by active summer fanning and honey ripening in a warm brood nest; stable temperature and perfectly stable acoustics confirm this is not a stress signal.▹ Action: On your next routine visit within 5–7 days, confirm fresh eggs and solid brood pattern — the 14-day warming trend and perfectly stable acoustics suggest an actively expanding brood nest at peak summer productivity; no urgent action needed.▹ Action: Monitor afternoon humidity lows — if they recur consistently below 40%, assess ventilation management for your setup.▹ Action: Tilt is 3° — within the ideal 0–5° range; no action needed.
