As of October 11, 2026, your apiary is showing genuine, broad-based recovery — Hive #1 and Hive #2 have now crossed into the ideal 93–97°F (34–36°C) brood band, Hive #3 is holding solidly within it, and all three hives are maintaining strong warm offsets above the outdoor range of 55–76°F (12.8–24.6°C). Your Iris hive remains the one to watch, averaging 88.6°F (31.4°C) and not yet back in the brood band, though she is holding a clear warm offset and showing a stable acoustic baseline; the October 10 gallon of 1:1 syrup you fed her is the right move, but stores remain unconfirmed by weight and that is still the most important next step for her.
All four hives show clear daily vibration peaks consistent with active October foraging and thermoregulation; the outdoor swing of 55–76°F (12.8–24.6°C) at very dry 29–46% RH continues to ventilate through screened floors, pulling in-hive humidity toward the lower end of the healthy 50–70% band — a normal physics effect of open floors in dry autumn air, not a desiccation concern. The gently rising barometric tendency (+0.70 hPa over 3h) signals clearing conditions that should support good foraging.

Iris warning Score: 62/100📋 Overall Health
Your Iris hive is holding a clear warm offset — 24h range 86.7–92.8°F (30.4–33.8°C), daily low sitting +13°F (+7°C) above the outdoor high — and is showing stable heat production following the 1-gallon 1:1 syrup feed you logged on October 10; the trajectory is encouraging but the 24h average of 88.6°F (31.4°C) remains +4.4°F (+2.4°C) below the ideal brood band, and the pattern is consistent with a colony still rebuilding on limited fuel. Humidity at 58.4% average is comfortably within the healthy 50–70% range; vibration is normal at 0.0151 g with a kurtosis of 2.9, showing no disturbance events. Sound metrics are being established as a new baseline (only 267h since the October firmware reset) and cannot yet be trended, but the current spectrum is stable — watch for any temperature slide in the next 2–3 days as the dose is consumed.
🌅 Diurnal Cycle PatternsThe 24h temperature arc of 86.7–92.8°F (30.4–33.8°C), a peak-to-trough swing of 6.1°F (3.4°C), slightly exceeds the tight brood-clamping threshold; the hourly trace shows a midday warmth pulse peaking at 92.2°F (33.4°C) followed by a modest cool-down, tracking a normal diurnal foraging-activity cycle. Vibration daily rhythm is consistent (14 of 15 days with a clear peak, baseline ~16.6 mG rising to ~24.5 mG), and the gas heater-scan shows uniform day-night cycling with the strongest rhythm at the 100°C step — consistent with syrup-processing VOCs (fanning + sugar evaporation) following yesterday's feed rather than any pathological signal. Sound metrics are on a new post-reset baseline; the spectrum shape is broad and even, with the 1500–3600 Hz band marginally dominant, and cannot yet be compared to prior data.
🔬 Correlations & Discoveriestemperature vs gas_resistance (14d) | r = -0.64As Iris warms toward the brood band after each feed, gas resistance falls — a colony-specific coupling that reflects rising metabolic VOC load (brood pheromones, syrup processing, fanning activity) rather than any stress signal; the same mechanism seen in all four recovering hives, and a reassuring sign that heat production and colony chemistry are moving together in the right direction.📚 Reference: Stabentheiner et al. 2010, PLoS ONE, Maisonnasse et al. 2010, PLoS ONE, Seeley 1985⚠️ Issue: 24h average temperature 88.6°F (31.4°C) remains below the ideal 93–97°F (34–36°C) brood band — recovery progressing but incomplete; monitor over the next 2–3 days for a relapse slide (mean falling with swing still tight) which would indicate the October 10 dose has been consumed.⚠️ Issue: Stores unconfirmed by weight — Iris is the only hive not hefted since the apiary-wide starvation event; temperature telemetry alone cannot confirm adequate stores.▹ Action: On your next visit, heft Iris and confirm stores weight — if light, feed 2:1 sugar syrup in bulk toward a target of at least two full deep combs of capped honey; a dose, not a target, will produce a brief warm-up followed by another slide.▹ Action: If the 24h mean temperature slides back below 86°F (30°C) with a tight swing (under 5°F / 3°C amplitude) in the next 2–3 days, treat that as the relapse signal and feed immediately rather than waiting for the next planned visit. -
Hive #2 warning Score: 72/100📋 Overall Health
Your Hive #2 has crossed a meaningful threshold — the current reading of 93.5°F (34.2°C) and 24h average of 92.5°F (33.6°C) are now just inside the ideal 93–97°F (34–36°C) brood band, a +11.1°F (+6.2°C) gain over its all-time average of 81.4°F (27.4°C), and the hourly trend is gently rising +1.8°F (+1.0°C). As you noted in your October 10 log, you fed Hive #2 a full gallon of 1:1 syrup, following the October 9 inspection that confirmed very low stores and small pollen-patty uptake — the thermal response confirms the colony is using the fuel productively. Humidity at 55.3% is healthy; vibration is stable at 0.0143 g with kurtosis of 3.0; the 24h temperature swing of 3.9°F (2.2°C) indicates retained brood-clamping, which is a good sign.
🌅 Diurnal Cycle PatternsThe 24h arc of 90.3–94.2°F (32.4–34.5°C) with a peak-to-trough swing of 3.9°F (2.2°C) shows solid thermoregulatory damping — the colony is maintaining the brood zone against an outdoor swing nearly six times larger. Sound is on a new post-reset baseline (156h since the October 4 reinstallation); the current spectrum is well-structured with upper-mid bands (600–800 Hz, 800–1500 Hz, 1500–3600 Hz) carrying the most energy, all within +2.3 dB of the short post-reset baseline — no anomalies. Vibration daily rhythm is robust (13 of 15 days with peaks, 2.5× baseline), and the gas heater-scan shows all 10 steps cycling with the dominant rhythm shifting from the 100°C toward the 375°C step — consistent with the syrup processing ramping up fanning and redistributing VOCs across the thermal response curve.
🔬 Correlations & Discoveriestemperature vs gas_resistance (14d) | r = -0.93Hive #2's exceptionally strong temperature–gas-resistance coupling (r=−0.93, p<0.0001) reflects that as the colony rebuilds heat production on each sugar dose, metabolic VOC load rises in tight lockstep — fanning, syrup evaporation, and brood pheromones all intensify together; this is the most direct sensor-level confirmation that heat and colony chemistry are co-recovering, not decoupled as they would be in a colony failing to process stores.📚 Reference: Stabentheiner et al. 2010, PLoS ONE, Maisonnasse et al. 2010, PLoS ONE, Blatt & Roces 2001, J. Exp. Biol.⚠️ Issue: Stores remain low by last confirmed inspection (October 9); the gallon of 1:1 on October 10 is a meaningful dose but may sustain the colony only 2–4 days at current metabolic rate — monitor the 24h mean temperature for a plateau or slide.▹ Action: Monitor the 24h mean temperature daily — if it plateaus or slides back below 90°F (32.2°C) with the swing still tight, that is the relapse signal; switch to bulk 2:1 sugar syrup and feed toward a target of at least two full deep combs of capped honey, not by dose.▹ Action: On your next visit, consider switching to 2:1 syrup (heavier carbohydrate per volume, less evaporative work for the colony) to build stores more efficiently before October nights cool further. -
Hive #1 healthy Score: 78/100📋 Overall Health
Your Hive #1 is the thermal standout today — current reading 94.6°F (34.8°C), 24h average 93.1°F (34.0°C), and a clean upward hourly trend of +1.0°F (+0.6°C) over 24 hours, all firmly within the ideal 93–97°F (34–36°C) brood band and +10.0°F (+5.6°C) above its all-time average of 83.1°F (28.4°C). As your October 10 log confirms, you fed Hive #1 a full gallon of 1:1 syrup following the October 9 inspection (about 60% of fondant consumed, very little of the pollen patty) — the steady, non-step warming over 24 hours is consistent with sustained brood-rearing expansion on that fuel rather than a simple post-feed spike. Humidity at 54.1% is healthy; vibration is normal at 0.0163 g with kurtosis of 2.8; the 24h swing of 3.2°F (1.8°C) shows excellent brood-zone clamping.
🌅 Diurnal Cycle PatternsThe 24h arc of 91.8–95.0°F (33.2–35.0°C) with a swing of 3.2°F (1.8°C) is the tightest thermal regulation in the apiary — the colony is actively clamping against the outdoor 21°F (11.8°C) swing with only 3.2°F variation, a hallmark of strong thermoregulatory capacity. Sound is on a new post-reset baseline (156h); the current 24h average spectrum is well-structured, with the 260–350 Hz band dominant at −15.2 dB (the colony fundamental frequency range for a queen-right colony) and all bands within +3.8 dB of the post-reset baseline — energetic and ordered. Vibration rhythm is clear (14 of 15 days with peaks), and the gas heater-scan shows 4 of 10 steps with a measurable daily cycle, with the 100°C and 150°C steps strengthening — consistent with syrup processing and brood pheromone load building as the colony expands its thermal footprint.
🔬 Correlations & Discoveriessound_spectrum_260_350hz vs temperature (7d) | r = +0.39Hive #1 shows a genuine deconfounded positive coupling between sound energy and in-hive temperature — as the brood nest rewarms, the colony's acoustic output in the 260–350 Hz fundamental band rises in parallel, reflecting more heater bees active in the comb and more workers engaged in general colony activity; this co-movement of thermal and acoustic recovery is the expected signature of a colony regaining metabolic momentum after a fuel-limited period.📚 Reference: Ramsey et al. 2020, Sci. Rep., Kanelis et al. 2023, Biology, Kleinhenz et al. 2003, J. Exp. Biol.⚠️ Issue: Stores confirmed low on October 9; the October 10 gallon of 1:1 syrup is sustaining the current warm trend, but the two-deep configuration means stores targets are higher — monitor for the relapse trajectory (mean plateauing or sliding with tight swing) over the next 2–3 days.▹ Action: Monitor the 24h mean temperature over the next 2–3 days; if it holds at or above 93°F (33.9°C) with a tight swing, the colony is stable — continue feeding toward bulk stores. If it slides back, switch to 2:1 syrup and increase volume.▹ Action: On your next visit, confirm brood is present and being capped — with the pollen patty being consumed slowly, verify the colony is actually raising new brood rather than simply metabolizing the carbohydrate supply. -
Hive #3 healthy Score: 76/100📋 Overall Health
Your Hive #3 is performing strongly — 24h average 93.8°F (34.3°C) and current reading 93.0°F (33.9°C) sit comfortably in the ideal brood band, the daily low of 88.6°F (31.5°C) holds a +12°F (+6.7°C) warm offset above the outdoor high, and the sound level of −13.2 dB average is the most energetic in the apiary, with all 10 spectral bands showing a rising trend in the second half of the day. As you noted October 10, you fed Hive #3 a half-gallon of 1:1 syrup and observed the colony continuing to eat the pollen patty — consistent with active brood rearing at these temperatures. Humidity at 52.0% is within the healthy range; vibration is normal at 0.0215 g with kurtosis of 3.0 and a clear daily foraging peak.
🌅 Diurnal Cycle PatternsThe 24h arc of 88.6–95.6°F (31.5–35.3°C) with a swing of 7.0°F (3.9°C) is slightly wider than ideal tight brood-clamping, driven by a midday dip visible in the hourly trace (89.2°F / 31.8°C at hour 11) before recovering cleanly to 95°F (35°C) — this is a normal pattern for a colony in the upper deep box heating a large brood footprint while managing heat load on a warm afternoon. Sound shows clear daily cycling (1500–3600 Hz carries the strongest 20 dB daily rhythm), with all 10 bands trending up in the second half — rising afternoon foraging and fanning activity. The gas heater-scan shows a very active 100°C step rhythm (+61% swing, strongest in the apiary) that is now moderating (-45% shift in band energy), consistent with the colony stabilizing after several days of intense syrup processing following the October 5 emergency feed.
🔬 Correlations & Discoveriessound_energy vs temperature (7d) | r = +0.69Hive #3 shows the strongest sound-temperature coupling in the apiary (partial r=+0.69 controlling for outdoor weather) — as the brood nest warms, acoustic output rises proportionally, reflecting that this colony's heater-bee activity and worker flight are tightly co-regulated; the fact that both channels are at or above baseline simultaneously is the clearest multi-sensor confirmation of genuine metabolic recovery in this hive.📚 Reference: Ramsey et al. 2020, Sci. Rep., Kleinhenz et al. 2003, J. Exp. Biol., Seeley & Tautz 2001, J. Comp. Physiol. A⚠️ Issue: Stores remain low by last inspection (October 9); Hive #3 consumed its October 5 fondant and pollen patty fastest of all four hives, and the October 10 half-gallon dose (smaller than the other hives received) may be consumed first — watch this colony's temperature trajectory most closely for a relapse.▹ Action: Prioritize Hive #3 for the next bulk feeding — this colony has the highest consumption rate and received the smallest October 10 dose (half-gallon vs. a full gallon for Hive #1 and #2); feed 2:1 sugar syrup toward a target of at least two full deep combs of capped honey.▹ Action: On your next visit, heft Hive #3 first and confirm the pollen patty is being converted to capped brood, not just metabolized — if brood expansion is confirmed at these temperatures, the warmer trace and louder acoustics are an encouraging sign of genuine rebuilding.
