Introduction: The Day My Sauna Got Smart {#introduction}
Picture this: It’s a freezing winter evening. You’re stuck in traffic, muscles tight from a long day, and all you can think about is the warmth of your sauna. But when you finally get home, you have to wait 30–45 minutes for it to heat up. By the time it’s ready, your motivation has evaporated.
Now imagine this instead: You’re leaving the office, pull out your phone, tap a button, and your sauna begins preheating. By the time you walk through the door, it’s waiting for you at the perfect temperature. That’s the promise of the SaunaBox Blebox.
The SaunaBox Blebox (also known as Blebox SaunaBox or simply Blebox sauna) is a WiFi-enabled smart controller that turns any traditional sauna into a connected, app-controlled wellness machine. It’s not just a gadget—it’s a lifestyle upgrade that brings centuries-old sauna traditions into the 21st century.
And here’s the kicker: you don’t need a new sauna to make this happen. The Blebox SaunaBox retrofits onto your existing setup, giving it superpowers overnight. Whether you have a backyard barrel sauna, a basement infrared unit, or a garden cabin, this little device can breathe new life into it.
What Exactly Is SaunaBox? {#what-is-saunabox}
Before we dive deep into the Blebox SaunaBox controller, let’s clarify something important: “SaunaBox” refers to two distinct but related things.
First, there’s SaunaBox the brand—a Los Angeles-based company that’s built a reputation for creating the world’s most accessible at-home saunas. They’ve sold over 100,000 units and offer everything from portable steam tents (the SmartSteam Pro) to full-spectrum infrared wooden cabins (the Solara) and traditional Finnish dry saunas (the Forge). Customers rave about the experience—one verified buyer called it “the best purchase I’ve ever made”, while another said it “provides a sauna experience that well exceeds the MSRP”.
But here’s where things get really interesting: SaunaBox also refers to the Blebox SaunaBox—a smart controller made by Blebox, a European electronics manufacturer. This is the device that makes your sauna “smart.” It’s a compact module (129 x 89 x 57 mm) that connects to your sauna’s heating system and gives you remote control via WiFi.
So when we talk about the SaunaBox Blebox, we’re talking about the controller—the brains behind the operation. And when we say Blebox sauna, we mean any sauna equipped with this brilliant little device.
The Blebox SaunaBox: Brains Behind the Heat {#blebox-saunabox}
The Blebox SaunaBox is, at its core, a WiFi-enabled sauna controller that replaces your old-school manual dials and timers. It’s designed for both single-phase (1x230V) and three-phase (3x230V) electric heaters, making it compatible with virtually any residential sauna setup.
Here’s what’s inside the box:
The device comes with a wired, waterproof temperature probe with a 5-meter cable. This probe is what gives you precise temperature readings—accurate to within half a degree Celsius. It’s the kind of precision that separates a mediocre sauna experience from a truly exceptional one.
Key Features That Make SaunaBox Blebox a Game-Changer {#key-features}
1. Remote Control from Anywhere in the World
This is the headline feature. Using the free wBox app (available on Android, iOS, and Windows), you can turn your sauna on or off, adjust the temperature, and check its status from anywhere with an internet connection. Blebox sauna control isn’t limited to your home network—you can preheat your sauna while you’re still at work, or check if you left it on while on vacation.
2. Intuitive Color-Changing Control Panel
The device features a backlit control panel with color lighting that shifts from blue through light blue, white, yellow, orange, to red. This isn’t just for show—it provides visual information about the current temperature. Users can set their own temperature ranges (e.g., 20°C to 80°C) and watch the color change smoothly as the heat builds.
3. Advanced Scheduling
The SaunaBox Blebox comes with a powerful time control function. You can program your sauna to turn on at specific times, with specific temperatures, or shut off automatically. Imagine waking up to a preheated sauna every morning, or coming home from work to one that’s perfectly warm.
4. Self-Diagnosis and Safety
The built-in self-diagnosis mechanism detects inconsistent configurations and recognizes probe failures. This isn’t just a convenience feature—it’s a safety feature that gives you peace of mind. The device also supports WPA2-PSK encryption and authenticated encryption with associated data (AEAD) for secure communication.
5. Open API for Smart Home Integration
Perhaps the most exciting feature for tech enthusiasts: the Blebox SaunaBox has an open API, making it easy to integrate with other home automation systems. This is where the SaunaBox Blebox truly shines for the smart home crowd.
Installation: From Box to Bliss in Minutes {#installation}
One of the most common questions about the Blebox SaunaBox is: “Is it hard to install?”
The short answer: No.
The longer answer: It’s surprisingly straightforward, even for non-electricians. Here’s the step-by-step:
- Mount the device – The SaunaBox Blebox is designed to fit in a standard surface junction box. It’s compact enough to mount discreetly near your sauna.
- Connect the temperature probe – The 5-meter waterproof probe needs to be placed inside the sauna where it can accurately measure the air temperature.
- Wire the heater – Connect your sauna heater to the controller’s relay outputs. The device supports up to 3 x 16A loads.
- Power it up – Connect to 230V AC power.
- Configure WiFi – The device creates its own WiFi network (named “saunaBox-xxxxxxxx”). Connect your computer or phone to this network, open a browser, go to, and select your home WiFi network.
- Download the app – Install the free wBox app from Google Play or the App Store.
- Start controlling – Your Blebox SaunaBox will be automatically detected by the app.
Users consistently praise how easy the setup is. One Trustpilot reviewer wrote: “Super, schnell und unkompliziert” (Super, fast and uncomplicated). Another noted: “Die Einrichtung war in wenigen Minuten erledigt” (Setup was done in a few minutes).
The wBox App: Your Sauna in Your Pocket {#wbox-app}
The wBox app is the command center for your SaunaBox Blebox. Available for free on Android, iOS, and Windows, it’s the interface that brings all the controller’s features to life.
What you can do with the wBox app:
- Turn the sauna on/off – The most basic, most used feature.
- Set target temperature – Dial in your perfect heat.
- Monitor current temperature – See exactly what’s happening inside.
- Create schedules – Set weekly routines for automatic heating.
- View interactive charts – Track temperature changes over time.
One user described the experience: “Über die App lässt sich alles einstellen und regeln. Auch von unterwegs.” (Everything can be set and controlled via the app. Even from on the go.)
That said, the app isn’t without its critics. Some users have reported glitchy performance, with one calling it “one of the most frustrating things to use”. However, the vast majority of reviews are positive, with the Blebox SaunaBox Pro earning a 4.7/5 rating from 33 verified customers.
Smart Home Integration: Sauna Meets Automation {#smart-home-integration}
This is where the SaunaBox Blebox truly separates itself from the competition. Thanks to its open API and μWiFi communication standard (compatible with 2.4GHz WiFi), the Blebox SaunaBox plays beautifully with major smart home platforms.
Home Assistant Integration
The Blebox SaunaBox integrates natively with Home Assistant as a climate entity. This means you can:
- Turn the sauna on and off via automations
- Set target temperatures from your dashboard
- Read current temperatures for monitoring
- Create complex automations (e.g., “If outside temperature drops below 10°C and it’s between 6-8 PM, preheat the sauna”)
One Home Assistant user shared: “I’ve been using a Blebox SaunaBox to control my sauna” and created a custom driver for full thermostat integration.
Hubitat Integration
Community developers have created Hubitat drivers for the Blebox SaunaBox, giving you full thermostat integration so you can control and monitor your sauna from dashboards, rules, and automations.
Homey Pro Integration
The Blebox SaunaBox also works with Homey Pro smart home hubs, with community-developed drivers available.
The Alexa Wish
There’s strong community interest in voice control. One App Store reviewer wrote: “I bought the Saunabox / wBox so I could use Alexa to control my sauna. I know about 100 sauna owners here in the US that would run out and buy Saunabox if it had this feature.” While native Alexa support isn’t officially available yet, the open API makes it technically possible for developers to build it.
SaunaBox PRO vs Standard: Which One Do You Need? {#pro-vs-standard}
The Blebox SaunaBox comes in two versions: standard and PRO.
The standard SaunaBox includes:
- Built-in WiFi antenna
- Backlit touch control panel
- All core features (remote control, scheduling, self-diagnosis)
The SaunaBox PRO adds:
The PRO version is ideal for:
- Outdoor saunas where WiFi signal might be weaker
- Garden saunas located far from the house
- Any installation where you want the maximum possible range
One retailer describes the PRO as “saunaBox controller with an antenna connector and an external antenna that increases the signal range. It will work great in outdoor, garden saunas, where the wider WiFi range is needed.”
If your sauna is indoors and relatively close to your router, the standard version should suffice. If you’re installing in a backyard cabin or a detached garage, spring for the PRO.
Real-World Performance: What Users Are Saying {#real-world-performance}
The SaunaBox Blebox has generated a lot of buzz, and real-world reviews paint a mostly positive picture.
The Good:
- Silent operation – “Świetna część, przełączniki przekaźnikowe są ciche” (Great part, the relay switches are quiet)
- Easy setup – “Die Einrichtung war in wenigen Minuten erledigt” (Setup was done in a few minutes)
- Comprehensive control – “Everything can be set and controlled via the app”
- Value for money – “Full recommendation, especially when you compare what other control units cost”
The Critiques:
- No built-in temperature display – Multiple users have noted this as a missing feature. One reviewer said: “Was absolut fehlt ist eine Temperaturanzeige am Gerät” (What’s absolutely missing is a temperature display on the device)
- App reliability – Some users have reported glitchy app performance
- Long-term durability questions – One user reported a failure after three years following a firmware update
The SaunaBox Brand Itself
The SaunaBox portable sauna products have their own enthusiastic following. Customers report:
- Reaching 130°F in 20 minutes
- 15-minute tool-free setup
- Fitting in a 3×3 foot space
- Improved sleep, clearer skin, and less post-gym soreness
However, some users have reported performance issues in cold climates. One Minnesota user noted: “After 45 minutes, it failed to reach anything close to adequate, let alone hot in a MN winter”.
Health Benefits Beyond the Heat {#health-benefits}
Why invest in a Blebox SaunaBox? Beyond the convenience, there’s a compelling health case.
The SaunaBox brand has been endorsed by health professionals. Dr. James LaValle (Chief Science Officer of Lifetime Fitness) said: “The SaunaBox trains the body to handle stress more effectively, increasing resilience and promoting a deep state of relaxation by pushing one’s physiological limits.”
Regular sauna use has been linked to:
