Humidor monitoring, done right.

Live humidity and temperature data for your cigar collection — with alarms that reach you before your cigars notice anything is wrong. Bring your own Govee or Shelly sensor; The Cabinet does the rest.

The problem

Your hygrometer is lying to you.

Most cigar loss happens to people who thought their humidor was fine. The dial reads 70%; the wrappers crack anyway. Mold blooms on a row of Cohibas you haven’t opened in a month. The Boveda packs are still spongy. None of it adds up — until you check with a calibrated sensor and discover the dial has been reading 5 to 10 points high since last winter.

Analog dial hygrometers drift. They’re typically accurate to ±5% RH on day one and degrade from there, especially after a salt-test calibration that nobody bothers to redo. Digital pucks fare a little better but still rely on you actually opening the humidor and reading the screen. Neither catches the moments that matter most: the afternoon you left the lid ajar, the radiator cycle that spiked the room 4°C, the slow Boveda exhaustion that happens over weeks.

Humidor monitoring fixes this by replacing “the dial says 70%” with a live, timestamped record. You stop guessing. You start knowing.

How it works

Three steps, one quiet dashboard.

Step 01

Drop a sensor in.

Connect a Govee or Shelly H&T Gen 3 sensor and sign in. Most cigar collectors are reading data within five minutes of unboxing.

Step 02

Set your thresholds.

Pick the humidity range that suits your style — 65 to 72% RH covers most collections. The Cabinet evaluates threshold, rate-of-change, and VPD-based alarms on every reading.

Step 03

The Curator watches.

Your AI Curator reads the data 24/7 — writes daily reports, explains anomalies in plain English, and answers questions you ask in Telegram or in the app.

Climate science, briefly

The numbers that actually matter.

Cigar humidity is not a single number. It’s the interplay between temperature, relative humidity, and the air’s capacity to hold moisture. The Cabinet computes all three so you can see what’s actually happening inside the wood.

What humidity should a humidor be?

The classical target is 70% RH at 18-21°C — what cigar makers in Cuba aim for. Many modern collectors prefer 65% for a drier, easier draw, especially in cooler climates. The right answer is “wherever your cigars taste best, held steady.” Drift is the enemy, not the absolute number.

What is VPD?

Vapor Pressure Deficit — the difference between how much moisture the air is holding and how much it could hold at the current temperature. A higher VPD means thirstier air, which pulls moisture out of your cigars even at “normal” RH. VPD catches stress that a raw humidity reading can hide.

What is dew-point margin?

The gap between current temperature and the dew point. When the margin shrinks toward zero, condensation forms — and condensation in a humidor means mold within 48 hours. The Cabinet warns you before the margin gets dangerous, not after you’ve lost a row of cigars.

From travel case to walk-in

One account. Every humidor you own.

Most cigar monitoring tools assume you have one humidor. Real collections rarely look like that. There’s the everyday desktop, the travel case for trips, the aging cabinet for special occasions, and — for some — a walk-in vault that needs multiple sensors just to get an honest read.

The Cabinet treats each humidor as a first-class object. Independent thresholds, independent alarm rules, independent dashboards — all in one account. For walk-ins and large cabinets, multiple sensors per humidor let you watch stratification: warmer at the top of the room, more humid near the floor, drier near the door seal.

Lounges and retailers run on the Salón plan, which adds white-label dashboards, dedicated SLA support, and walk-in humidor features tuned for venues that can’t afford a humidity excursion to surprise them on a Saturday night.

Compatible sensors

You don’t buy a sensor from us.

The Cabinet is the dashboard, alarm engine, and AI Curator on top of your hardware. Buy a Govee or Shelly directly from the manufacturer or any electronics retailer; we recommend specific models on the FAQ.

  • · Govee WiFi & gateway-connected sensors — any Govee temp/humidity sensor that reports through the Govee Cloud, whether WiFi-native (e.g. H5179) or BLE behind a Govee gateway (H5151 with H5110 and similar). Updates land in your dashboard within seconds.
  • · Shelly H&T Gen 3 — WiFi-connected sensor, polled on a tight schedule. Battery-friendly and ideal for walk-ins. Webhook-push support is on the roadmap.
  • · WiFi-only today — more sensor families on the roadmap. Got a specific model in mind? Send a request and we’ll prioritise it.
Common questions

About humidor monitoring.

Do I need to replace my analog hygrometer? +
No. The Cabinet layers on top of whatever you already have. Many serious cigar collectors keep their analog hygrometer as a visual cue inside the humidor, and use The Cabinet for the actual data — alarms, trends, and the historical record.
How accurate are smart humidor sensors compared to analog ones? +
Considerably more accurate, and far more stable over time. A factory-calibrated Govee or Shelly sensor reports humidity within ±3% RH and temperature within ±0.3°C per manufacturer spec. Analog dial hygrometers typically arrive at ±5% RH out of the box and drift further within 6 months. The Cabinet shows you the actual number every time you check; no guesswork.
How fast do humidity alerts arrive? +
Quickly enough to matter. Both Govee and Shelly H&T sensors report via WiFi to their respective cloud APIs, and The Cabinet polls on a regular cycle. Alarm thresholds are evaluated on every reading and a Telegram message goes out the moment a breach is detected. Webhook-push support is on the roadmap, which will tighten this further.
Can I monitor multiple humidors at once? +
Yes — that's a core design goal. Maestro and Salón plans are unlimited on humidors, sensors, and history. Each humidor gets a dedicated dashboard with its own alarm thresholds. Walk-in humidors and large cabinets can use multiple sensors per humidor, and The Cabinet shows you the spread between sensors so you can spot stratification (warmer at the top, more humid near the floor).
What's the smallest humidor that's worth monitoring? +
Anything you care about. We have collectors monitoring 25-count travel cases and members' lounges with walk-in vaults on the same account. The smaller the humidor, the faster it reacts to lid-opens and ambient changes — which is exactly when monitoring is most useful.
