Govee H5179: Wi-Fi Monitoring for Your Cave

The Govee H5179 is all about peace of mind. Its main advantage is built-in Wi-Fi, allowing you to check the temperature and humidity of your cheese cave from anywhere using your phone. This isn’t just a novelty; it’s a practical tool for anyone who can’t be home all the time.

Imagine you’re on vacation or stuck at work and a power outage trips the breaker to your cheese fridge. With a simple digital thermometer, you wouldn’t know until it’s too late. The Govee app will send an alert to your phone the moment conditions go outside your preset safe range, giving you a chance to call a neighbor or race home to save your precious cheese. The app also stores historical data, letting you see trends over days or weeks, which is incredibly useful for troubleshooting a cheese that didn’t turn out quite right.

For its price, the Govee provides an immense amount of value. It combines remote monitoring, data logging, and customizable alerts into one affordable package. It’s the perfect "set it and forget it" solution for the modern cheesemaker who wants to stay connected to their craft, even when they’re away from the farm.

Inkbird ITC-308: Temperature Control & Safety

The Inkbird ITC-308 isn’t just a thermometer; it’s a thermostat controller. This is the device you need if you’re converting a refrigerator or chest freezer into a dedicated cheese cave. It actively manages your environment rather than just reporting on it. You plug the Inkbird into the wall, then plug your fridge into the Inkbird’s "cooling" outlet.

You set your target temperature (say, 52°F) and a differential (maybe 2°F). The Inkbird will turn the fridge on when the temperature rises to 54°F and turn it off when it cools back down to 52°F. This simple action is the key to maintaining the stable environment cheese needs to ripen properly. A standard refrigerator thermostat is designed for much colder temperatures and wider swings, which is terrible for cheese.

Crucially, the Inkbird has built-in safety features that protect your equipment. A programmable compressor delay prevents the fridge from cycling on and off too quickly, which can burn out the motor. It also has high and low temperature alarms to warn you of a malfunction. The Inkbird is the non-negotiable workhorse for any serious DIY cheese cave. It’s not for monitoring; it’s for control.

ThermoPro TP65: Wireless Indoor/Outdoor Gauge

Think of the ThermoPro TP65 as a convenient dashboard for your cheese cave. It consists of a remote sensor that you place inside your aging space and a large base station that you keep in your kitchen or workshop. This setup allows you to see the current temperature and humidity at a glance without ever opening the cave door.

Every time you open your cave, you disrupt the carefully balanced environment inside. The TP65 minimizes this by giving you the data you need from up to 200 feet away. The display is large, backlit, and easy to read, showing data from up to three remote sensors simultaneously. This is great if you have multiple aging boxes or zones with different conditions.

The main tradeoff here is the lack of Wi-Fi. You can’t check it when you’re away from home, and it doesn’t log historical data for analysis. But for simple, real-time, at-home monitoring, it’s a fantastic and reliable option. It strikes a great balance between the basic AcuRite and the fully-connected Govee.

AcuRite 00613: A Simple, Reliable Digital Unit

Sometimes, the best tool is the simplest one. The AcuRite 00613 is a small, inexpensive, and dependable digital thermometer/hygrometer that does one thing: it tells you the conditions inside your cave. There are no apps, no wireless signals, and no alerts. You stick it inside and open the door to read it.

Why would you choose this? For one, it’s incredibly cheap, making it a perfect entry point for a new cheesemaker. It’s also an excellent backup. Many of us run a sophisticated system like a Govee or Inkbird but keep a simple AcuRite inside as a sanity check. If your fancy sensor starts giving a weird reading, a quick check against the AcuRite can confirm if you have a real problem or just a sensor failure.

Its small size means it can fit inside smaller aging boxes or even a large Ziploc bag for creating a micro-environment. While it lacks advanced features, its reliability and low cost make it an essential piece of kit. Never underestimate the value of a simple, trustworthy backup.

SensorPush HT1: Compact Wireless Data Logging

The SensorPush HT1 is for the cheesemaker who obsesses over data. This tiny, button-sized sensor is known for its accuracy and its powerful app. It connects to your phone via Bluetooth and continuously logs temperature and humidity data, storing it on the device until you sync it.

The real power of the SensorPush is in its data analysis. The app provides clean, detailed graphs that are easy to manipulate. You can zoom in on specific timeframes to see exactly how your cave responded to a change you made or how conditions fluctuated over a three-month aging period. This level of detail is invaluable for perfecting your process and replicating a successful cheese.

The primary consideration is its reliance on Bluetooth. You have to be within range (typically 30-50 feet) to sync the data and get real-time readings. SensorPush sells a separate Wi-Fi gateway to give you remote access and alerts like the Govee, but this significantly increases the cost. Without the gateway, it’s a top-tier data logger for close-range analysis, not a remote alert system.

Extech RHT30: USB Datalogger for Precision

The Extech RHT30 is a different beast entirely. It’s a professional-grade datalogger designed for situations where precision and documentation are paramount. It has no screen and no wireless connectivity. You program it on your computer, place it in your cave, and let it record data for days, weeks, or months.

When you’re ready to analyze the data, you retrieve the device and plug its USB interface directly into your computer. The accompanying software generates detailed PDF reports and Excel spreadsheets, complete with graphs and summary statistics. This is overkill for many, but it’s perfect for the cheesemaker who is methodically testing variables or needs to prove their process is stable.

Think of this as a tool for deep-dive analysis, not for daily checks. You won’t get alerts if your fridge fails. But if you’re trying to figure out why your cheddars are developing a bitter taste at the six-month mark, the detailed historical data from an Extech could reveal subtle temperature fluctuations that other devices might miss. It’s for the scientist in every cheesemaker.

Calibrating Your ThermoPro and AcuRite Sensors

Affordable sensors are fantastic, but you can’t always trust their out-of-the-box accuracy. A sensor that’s off by even 5% humidity can ruin a delicate bloomy rind. This is why calibration is not optional; it’s a fundamental part of using these tools.

For humidity, the "salt test" is the gold standard.

• Mix table salt with a little water in a small dish until it’s the consistency of wet sand.
• Place the dish and your sensor inside a sealed Ziploc bag or airtight container.
• After 8-12 hours, the air inside the container will stabilize at exactly 75% relative humidity.
• Check your hygrometer’s reading. If it reads 80%, you know it’s off by +5%. If it reads 71%, it’s off by -4%.

For temperature, an ice water bath is just as simple. Fill a glass with crushed ice and add just enough cold water to fill the gaps. After a few minutes, the water will be 32°F (0°C). Submerge the probe (not the whole unit!) and check the reading. Note any deviation and mentally adjust your readings going forward. Do this every six months to ensure your cheese is aging in the conditions you think it is.

Govee vs. SensorPush: App and Alert Features

Choosing between the two most popular smart sensors often comes down to a single question: do you need remote access out of the box? The Govee H5179 has Wi-Fi built-in, meaning you can set it up and immediately get alerts and check data from anywhere with an internet connection. This is its killer feature, especially for the price.

The SensorPush HT1 uses Bluetooth, so its remote capabilities depend on an additional purchase: the G1 Wi-Fi Gateway. While the SensorPush sensor itself is often praised for its high accuracy and compact size, the total cost for remote monitoring is significantly higher than the Govee. Without the gateway, it’s a fantastic local data logger, but you won’t get an alert if your fridge dies while you’re at the grocery store.

Both apps are excellent, offering clean graphs and data export options. Govee’s app is robust and user-friendly, making it easy to set alert thresholds for temperature, humidity, or both. SensorPush’s app feels a bit more polished and is geared toward deep data analysis. The choice is clear: if your primary need is affordable, all-in-one remote alerts, Govee is the winner. If your priority is maximum accuracy and you’re willing to invest more for remote access or only need local data logging, SensorPush is a worthy contender.

Ultimately, the best thermometer for your cheese cave depends on your goal. Whether you need the active control of an Inkbird, the remote vigilance of a Govee, or the simple reliability of an AcuRite, the right tool is out there. Investing a little money in accurate monitoring is the cheapest insurance you can buy to protect the time, effort, and passion you pour into every wheel of cheese.
