As of October 14, 2026, three of your four hives are holding solid brood-band temperatures with Iris, Hive #1, and Hive #2 all averaging 93–95°F (34–35°C) — a genuine improvement from the low-20s readings of a few weeks ago. The one thread that remains unresolved across the whole apiary is confirmed stores: October is shortening the foraging window daily, the last feeding round was four days ago, and hefting every hive on your next visit is the single most important action you can take before winter.
All three in-hive sensors with full gas data (Iris, Hive #1, Hive #3) show a sustained negative partial correlation between in-hive temperature and gas resistance (r = −0.65 to −0.94, controlling for outdoor weather) — consistent with brood pheromone load, syrup-processing volatiles, and fanning activity all rising together as the colonies rebuilt their brood nests after the October feeding round (Maisonnasse et al. 2010; Basile, Pirk & Tautz 2008).
All four hives show clear daily vibration activity rhythms (10–14 of 15 days with distinct afternoon peaks), consistent with October foraging on shortened daylight; outdoor conditions of 55–71°F (13–22°C) at 34–49% RH are pulling in-hive humidity toward the lower end of the healthy 50–70% band through the screened floors — normal ventilation physics for open-bottom Apimaye hives.

Iris healthy Score: 76/100📋 Overall Health
Your Iris hive has resolved the relapse concern flagged yesterday — the 24h average of 93.2°F (34.0°C) sits at the ideal floor and the hourly trace has been rising +1.0°F (+0.6°C) over the last 12 hours, now reading 94.6°F (34.8°C), up from the 90.4°F (32.5°C) low seen earlier in the window; your October 10 log of 1 gallon of 1:1 syrup lines up with the sustained acoustic surge (+14 dBFS over 14 days) and the gas resistance step-down around October 6, both consistent with active syrup processing and brood pheromone buildup. Humidity is healthy at 57.3% average; the primary open item remains confirming stores by weight on your next visit — a continued rise toward 94–95°F (34–35°C) is encouraging, but telemetry cannot see what is in the cells.
🌅 Diurnal Cycle PatternsThe 24h swing of 90.4–94.8°F (32.5–34.9°C) = 4.4°F (2.4°C) peak-to-trough is well within the healthy brood-clamping threshold, and the hourly trace shows a smooth rising arc rather than the mid-period dip that characterized the relapse pattern; the acoustic spectrum is the most energetic in the apiary (+14 to +18 dB above all-time baseline across all bands), with the dominant rhythm band having shifted from 1500–3600 Hz toward 420–500 Hz over the second half of the window — consistent with increased lower-frequency buzzing during active syrup curing; vibration is stable at 0.0167 g average with kurtosis 2.6 (slightly smooth, no impulsive events) and a dominant 80–120 Hz band, with 14 of 15 days showing clear afternoon activity peaks; the gas heater-scan shows a persistent low-resistance profile (320°C step ~316 kΩ vs. all-time avg ~386 kΩ), with the low-temperature steps (100–200°C) shifted ~24–26% lower than earlier in the window, reflecting elevated volatile load from syrup processing and brood pheromones — this is a colony phenomenon, not a concern.
🔬 Correlations & Discoveriessound_energy vs gas_resistance (14d) | r = -0.79The partial correlation between gas resistance and in-hive temperature (r = −0.79, controlling for outdoor weather) reflects the brood-nest expansion arc: as the colony rebuilt its brood zone after the October feeding round, rising heater-bee activity increased both temperature and the circulating load of brood pheromones (E-β-ocimene) and syrup-processing volatiles, driving MOX resistance lower — a healthy metabolic coupling, not a distress signal.📚 Reference: Maisonnasse et al. 2010, PLoS ONE 5(10):e13531, Basile, Pirk & Tautz 2008, Zoology 111:433–441⚠️ Issue: Stores unconfirmed by weight — the October 10 gallon of 1:1 syrup is likely approaching or past exhaustion; telemetry cannot confirm adequate reserves.▹ Action: On your next visit, heft Iris and feed bulk 2:1 sugar syrup toward a confirmed stores target of at least two full deep combs — a gallon of 1:1 is a dose, not a winter stores target. -
Hive #2 warning Score: 72/100📋 Overall Health
Your Hive #2 is holding its brood temperature with remarkable precision — the 24h range of 92.9–95.0°F (33.9–35.0°C) with a 2.1°F (1.2°C) swing and a flat hourly trace locked at 94.3°F (34.6°C) average is textbook brood-nest clamping, +12.1°F (+6.7°C) above its all-time average; your October 9 inspection and October 10 feeding logs confirm the colony was low on stores and received a gallon of 1:1 syrup, and the sustained 9.6°F (5.3°C) warming drift over 14 days reflects genuine brood-nest recovery. Humidity at 53.7% is healthy; the watch flag is carried by the battery, now at 3844 mV and draining 76 mV in 24 hours — below the all-time low of 3916 mV and trending toward the caution zone.
🌅 Diurnal Cycle PatternsThe 24h temperature swing of 2.1°F (1.2°C) is the tightest in the apiary, consistent with a well-insulated Apimaye enclosure running active brood clamping; sound is reported as a new post-reset baseline (sensor was out of the hive October 4–9) — the current 24h average of −40.3 dBFS with a dominant 800–1500 Hz band and per-band deltas of +2.6 to +5.0 dB above the post-reset baseline represent this hive's emerging acoustic fingerprint, and no trend comparisons to pre-reset data are meaningful; vibration is stable at 0.0164 g average with kurtosis 3.1 (normal), dominant 80–120 Hz band, and 10 of 15 days showing afternoon activity peaks — the 160–200 Hz fanning rhythm has weakened in the second half of the window, consistent with October's cooler temperatures reducing ventilation demand; the gas heater-scan at 39.9 kΩ (320°C step) is close to this hive's all-time average of 49.8 kΩ, with the low-temperature steps (100–200°C) shifted ~16–19% lower recently — likely driven by syrup-processing VOCs and the strong deconfounded temperature/gas coupling (r = −0.94) seen in the multivariate analytics.
🔬 Correlations & Discoveriestemperature vs gas_resistance (14d) | r = -0.94The strongest temperature–gas coupling in the apiary (r = −0.94, deseasonalized residuals) reflects a single colony-state arc: as the brood nest warmed from ~79°F (26°C) to ~94°F (34.6°C) after October feeding, heater-bee activity and brood pheromone load rose together, driving MOX resistance lower — the tight r value indicates this hive's gas channel is an unusually clean metabolic proxy for brood-nest activity, grounded in the known coupling between E-β-ocimene emission and brood mass (Maisonnasse et al. 2010).📚 Reference: Maisonnasse et al. 2010, PLoS ONE 5(10):e13531, Seeley 1985, Honeybee Ecology⚠️ Issue: Stores confirmed low at October 9 inspection; the October 10 gallon of 1:1 syrup is likely near or past exhaustion — monitor for a mean slide below 92°F (33.3°C) as the relapse signal.⚠️ Issue: Battery at 3844 mV, draining −76 mV in 24 hours, now below the all-time low of 3916 mV — approaching the caution zone; plan to recharge on your next visit.▹ Action: On your next visit, heft Hive #2 and feed bulk 2:1 sugar syrup toward a confirmed stores target of at least two full deep combs; switch to 2:1 concentration (more carbohydrate per volume, less evaporative work) as October nights cool further.▹ Action: Recharge the Hive #2 battery on your next visit — at the current drain rate it will approach 3700 mV within a few days; address before it nears the ~3500 mV caution floor. -
Hive #1 healthy Score: 79/100📋 Overall Health
Your Hive #1 continues its impressive run — the 24h range of 94.1–95.1°F (34.5–35.1°C) with only a 1.0°F (0.6°C) swing and a perfectly flat hourly trace is the tightest brood clamping this hive has ever recorded, sitting +9.6°F (+5.3°C) above its all-time average of 85.0°F (29.5°C) and squarely in the ideal band; your October 9 inspection (low stores, ~60% fondant consumed) and October 10 gallon of 1:1 syrup log align with the 12.4°F (6.9°C) warming drift over 14 days. Humidity at 52.7% is healthy, vibration is steady, and the relapse watch remains open — confirmed stores by weight on your next visit is the one thing telemetry cannot provide.
🌅 Diurnal Cycle PatternsThe 1.0°F (0.6°C) 24h swing is the most tightly clamped brood reading in the apiary, reflecting both active thermoregulation and the Apimaye enclosure's high wall R; sound is reported as a new post-reset baseline — the 24h average of −18.5 dBFS with a dominant 260–350 Hz band and all per-band deltas within +2 to +5 dB of the post-reset baseline is this hive's emerging acoustic fingerprint; the second-half-of-day sound energy shows a broad gentle decline across most bands (−1 to −2 dB), consistent with the natural late-October foraging taper as daylight shortens; vibration is stable at 0.0152 g average with kurtosis 3.1 (normal), dominant 80–120 Hz band, and 11 of 15 days showing afternoon peaks; the gas heater-scan at 340 kΩ (320°C step) is below this hive's all-time average of 436 kΩ, with mid-temperature steps (200–280°C) shifted ~12–13% lower recently, consistent with brood pheromone and syrup-processing VOC load correlating with the brood nest's recovery (partial r = −0.86 controlling for outdoor temperature).
🔬 Correlations & Discoveriessound_energy vs temperature (14d) | r = +0.68The partial correlation between sound energy and in-hive temperature (r = +0.68, controlling for outdoor weather) captures the colony's brood-nest rebuild: as heater-bee density and brood mass increased after October feeding, both the acoustic energy from colony metabolism and the temperature rose together — consistent with Kleinhenz et al.'s finding that heater-bee clusters produce coordinated thermal and vibrational output as brood area expands.📚 Reference: Kleinhenz, Bujok, Fuchs & Tautz 2003, J. Exp. Biol. 206:4217–4231, Ramsey et al. 2020, Sci. Rep. 10:9798⚠️ Issue: Stores confirmed low at October 9 inspection; the October 10 gallon of 1:1 syrup is likely near exhaustion — watch for a mean slide or swing widening as the relapse signal.▹ Action: On your next visit, heft Hive #1 and feed bulk 2:1 sugar syrup toward a confirmed stores target of at least two full deep combs; the stable temperature is encouraging but cannot confirm what is in the cells. -
Hive #3 warning Score: 58/100📋 Overall Health
Your Hive #3 is the warmest and most acoustically active hive in the apiary — the 24h average of 95.7°F (35.4°C) with a stable hourly trace is solidly in the ideal band — but the battery situation has become urgent: at 3612 mV and draining 158 mV in 24 hours, it has fallen 168 mV below its previous all-time low of 3780 mV and will approach the ~3500 mV sensor-degradation floor within roughly one day; your October 10 log confirms only a half-gallon of 1:1 syrup (half the dose of Hive #1 and #2) while the colony continues consuming the pollen patty, meaning carbohydrate demand remains elevated. Humidity at 43.7% average is at the dry end of the healthy range, driven by the upper-box sensor placement and October's dry ambient air — no desiccation concern, but worth watching.
🌅 Diurnal Cycle PatternsThe 24h swing of 94.1–96.2°F (34.5–35.6°C) = 2.1°F (1.2°C) is well clamped; sound is a new post-reset baseline — the 24h average of −12.4 dBFS with a dominant 260–350 Hz band is this hive's emerging acoustic fingerprint, with a 2.0 dBFS declining trend in the second half of the day consistent with the October foraging taper; vibration is stable at 0.0176 g average with kurtosis 3.0 (normal), dominant 80–120 Hz band, and 12 of 15 days showing afternoon peaks with a shift in dominant rhythm band from 20–50 Hz to 50–80 Hz; the gas heater-scan at 101 kΩ (320°C step) is near this hive's all-time average of 105 kΩ, with high-temperature steps (375–400°C) shifted ~19–20% lower recently and the strongest daily gas rhythm (100°C step, +48% swing) weakening compared to earlier in the window — consistent with the brood-nest reaching a steady metabolic state after the October warming step.
🔬 Correlations & Discoveriessound_energy vs temperature (14d) | r = +0.78The strongest sound-temperature partial correlation in the apiary (r = +0.78, controlling for outdoor conditions) in Hive #3 reflects the upper-box sensor capturing the warmest, most acoustically active zone of the hive — as the cluster expanded upward after feeding, both brood temperature and colony acoustic output rose together, a well-documented signature of increasing heater-bee density and metabolic activity (Kleinhenz et al. 2003).📚 Reference: Kleinhenz, Bujok, Fuchs & Tautz 2003, J.
