Every series from every reporting device at the facility ends between 22:09 and 22:12 UTC on 2026-05-25. Before that moment, the substrate sensors were reporting on a clean 3-minute cadence with zero gaps over 30 minutes for 4.3 straight days. Batteries on all 12 nodes read 100% at last communication. This pattern rules out node radios, batteries, and individual sensors: the failure is upstream — the gateway ("veg 5 nova core", H2110001107) lost power or the site lost its internet uplink. The gateway, sink and Climate One are PoE-powered, so the first physical check is the PoE switch / power circuit feeding the head-end, then the uplink.

"Node ×2" = paired radio units sharing a position (-2 suffixed serials), each hosting a TEROS One substrate sensor. 12 node radios + 12 TEROS One total.

The trial in F9 ("novacore vs bio", zones "zone 1 nova" vs "bio") was producing clean data right up to the outage. These are observed ranges from the final 4.3 days — shown for context only; this is NOT a 14-day audit window.
| Signal | Zone 1 nova (6 TEROS One) | Bio zone (6 TEROS One) |
|---|---|---|
| Substrate VWC (median per sensor) | 30.2 – 50.0 % | 22.9 – 63.0 % |
| Pore EC (typical, mS/cm) | p50 ≈ 3.6 | — |
| Substrate temp | ≈ 78.4 °F | ≈ 78 °F |
| Climate (Climate One, zone 1 nova) | Observed May 21–25 |
|---|---|
| Air temperature | 74.6 – 82.1 °F (p50 78.9) |
| Relative humidity | 46.8 – 72.6 % (mean ≈ 56) |
| CO₂ | 850 – 1397 ppm (p50 1335) |
Per-sensor VWC medians spread 23–63% across the bio zone — wide position-to-position variation worth reviewing once data is restored. Sensor H3440012461 (TEROS One) also logged one 2-day internal gap before the outage and is worth watching after recovery. No dryback or irrigation-phase metrics are quoted here: with no series after May 25 and no configured harvest group, computing them would require fabricating data.
The scheduled 14-day audit window (2026-05-28 → 2026-06-11) contains zero sensor data: the facility went dark three days before the window opened. Coverage is 0% of the required ≥90%. Per audit rules, missing days are never synthesized or modeled, so no cultivation audit is published for this window.
Additionally, the facility has no active harvest groups — the last two HGs ended in September 2025 (F22 and Flower 5 runs). The F9 trial has been running without a configured harvest group, which means no phase context (P0–P3 irrigation day structure, steering targets) can be attached to its data even when the mesh returns.
Palatka runs the new-generation fleet: 12× TEROS One substrate sensors + Climate One. On 2026-06-09 Richard Callahan flagged TEROS One reading 5–15% higher VWC than TEROS 12 on replacement units. As already communicated to Richard: the two sensor families measure VWC and EC differently and are expected to read differently — TEROS 12 is being phased out in favor of TEROS One. Recommend the training session include a short "reading the TEROS One" segment so site teams stop comparing it 1:1 against TEROS 12 history.
