Saunabox Blebox Review 2026: Is This WiFi Sauna Controller Worth It?

The Problem That No One Was Talking About

Picture this: It’s a freezing winter evening. You’ve had a long, exhausting day. All you want is to step into your sauna, let the heat melt away the stress, and emerge feeling reborn. But there’s one problem—your sauna is cold. Completely cold. And now you have to wait 45 minutes for it to heat up while you sit there, impatient and frustrated.

For decades, this was the reality for sauna owners around the world. You couldn’t preheat your sauna before you got home. You couldn’t check the temperature from your phone. You couldn’t schedule your sessions. You were essentially stuck in the dark ages of heat therapy.

Then came the Saunabox Blebox—and everything changed.

The Saunabox (also known as the Blebox Saunabox or Saunabox Blebox) is the world’s first WiFi-enabled sauna controller that lets you turn your sauna on and off and control the temperature from anywhere in the world. No additional peripherals. No complicated installations. Just pure, effortless control at your fingertips.

But is it really as good as it sounds? Does it actually deliver on its promises? And most importantly—is it worth your money?

Let’s dive in.

What Exactly Is the Saunabox Blebox?

The Saunabox Blebox is a compact, WiFi-enabled sauna controller manufactured by BleBox, a European company known for innovative smart home solutions. At its core, it’s a smart relay controller that connects to your sauna heater and allows you to control it remotely via a smartphone app.

But calling it just a “controller” is like calling a smartphone just a “phone.” The Blebox Saunabox is so much more than that.

The Two Sides of Saunabox

It’s worth noting that “Saunabox” refers to two distinct product lines:

1. The Blebox Saunabox Controller – A WiFi-enabled smart controller that retrofits any traditional sauna, turning it into a smart, remotely controllable wellness device.

2. Saunabox Portable Saunas – A range of portable steam and infrared saunas that include built-in smart controls.

This article focuses primarily on the Blebox Saunabox controller—the device that’s transforming how people interact with their existing saunas.

Technical Specifications at a Glance

These specs might look like technical jargon, but here’s what they actually mean for you: the Saunabox Blebox is powerful enough to handle virtually any residential sauna heater while consuming less energy than a nightlight.

Why the Saunabox Blebox Is a Game-Changer

Let me share a quick story.

My friend Mark is a sauna enthusiast. He built a beautiful outdoor sauna in his backyard—cedar walls, proper ventilation, the works. But there was one thing that drove him crazy: he couldn’t use it spontaneously.

“Every time I wanted to use the sauna, I had to wait almost an hour for it to heat up,” he told me. “By the time it was ready, I’d often lost the motivation or got distracted by something else.”

Then he installed the Blebox Saunabox.

Now, Mark preheats his sauna from his office before leaving work. He checks the temperature on his phone during his commute. By the time he walks through his back door, his sauna is perfectly heated and waiting for him.

“It’s honestly changed my life,” he says. “I use my sauna three times as often now. It’s not an event anymore—it’s just part of my daily routine.”

This is the real power of the Saunabox Blebox. It doesn’t just add a feature; it transforms a behavior. It removes friction. It makes wellness effortless.

The Core Benefits

• Remote Control from Anywhere – Turn your sauna on or off, adjust the temperature, and monitor its status from any location with internet access.

• Scheduling Capabilities – Set your sauna to turn on at specific times with specific temperatures.

• Visual Temperature Feedback – The device features a color-changing backlit panel that shifts from blue through white, yellow, orange, and red based on the current temperature.

• Manual Control Options – Touch buttons on the device panel allow for direct control even without a smartphone.

• Self-Diagnosis – The system detects incompatible settings and sensor failures, alerting you to potential issues.

Key Features That Make the Saunabox Stand Out

1. World-First Remote Control

The Saunabox is the first sauna controller that allows you to turn your sauna on and off and control the temperature from anywhere in the world without additional peripherals. This isn’t just a marketing claim—it’s a genuine technological breakthrough.

2. Dual Control Methods

You’re not locked into using your phone. The Saunabox Blebox offers:

• Remote control via the wBox app on iOS or Android

• Direct control via touch buttons on the device panel

• Wireless button control using the inBox module

• μRemote remote control compatibility

3. Intelligent Temperature Display

The device doesn’t just show numbers—it communicates through color. The backlit panel shifts through a spectrum of colors based on the current temperature, giving you an instant visual read on your sauna’s status from across the room.

4. Advanced Scheduling

Set your sauna to turn on with the last used temperature, a specific programmed temperature, or shut off at user-convenient times. This is perfect for morning routines or post-workout recovery sessions.

5. PRO Version for Extended Range

For outdoor or garden saunas where WiFi range might be an issue, the Saunabox PRO version includes an external antenna connector that significantly extends the signal range.

6. Open API for Smart Home Integration

The Saunabox Blebox features an open API that allows for seamless integration with various smart home systems. This means it can be part of a broader connected ecosystem rather than operating in isolation.

How to Set Up Your Saunabox in Minutes

One of the most impressive aspects of the Blebox Saunabox is how easy it is to set up. Here’s a step-by-step breakdown:

Step 1: Install the Hardware

The Saunabox is designed for surface mounting and comes in a compact, halogen-free polyurethane housing with an IP44 protection rating. Installation involves:

1. Mounting the device near your sauna control wiring

2. Connecting the temperature sensor probe (5m waterproof cable included)

3. Wiring the relay outputs to your sauna heater (supports both single-phase and three-phase configurations)

⚠️ Important: Always observe local electrical safety regulations. If you’re not comfortable with electrical work, hire a qualified electrician.

Step 2: Connect to WiFi

The Saunabox Blebox supports three connection modes:

• Direct connection (as an Access Point)

• WiFi connection via a standard router

• Remote access from anywhere with internet access

The device uses µWiFi technology, which is compatible with standard 2.4GHz WiFi networks.

Step 3: Download the App

The wBox app is available for:

• Apple iPhone and iPad

• Android devices

• Any device with an HTML5-compatible browser

Step 4: Start Controlling

Once set up, you can immediately start controlling your sauna from anywhere in the world. Users report that the entire setup process takes just minutes.

“Super teil, das Relais schaltet schön leise, die App ist leicht verständlich. Die Einrichtung war in wenigen Minuten erledigt.”

Smart Home Integration: The Blebox Ecosystem

The Saunabox Blebox isn’t just a standalone device—it’s part of a broader smart home ecosystem that includes products like thermoBox, gateBox, shutterBox, and switchBox.

Home Assistant Integration

Perhaps most exciting for smart home enthusiasts is the native Home Assistant integration. The Saunabox appears as a climate entity in Home Assistant with full support for:

• Setting target temperature

• Reading current temperature

This means you can:

• Automate your sauna based on your schedule or other triggers

• Monitor your sauna from your Home Assistant dashboard

• Create complex automations involving your sauna and other smart devices

Hubitat Support

The community has also developed a Hubitat driver for the Blebox Saunabox, giving you full thermostat integration so you can control and monitor your sauna from dashboards, rules, and automations.

Open API

The Saunabox features an open API that makes it easy to integrate with virtually any smart home platform. This flexibility is a massive advantage over proprietary, locked-down systems.

Saunabox vs. Traditional Sauna Controllers

The comparison is clear: the Blebox Saunabox offers capabilities that traditional controllers simply can’t match, often at a lower price point.

Real User Reviews: What People Are Saying

The Saunabox Blebox has garnered overwhelmingly positive reviews across multiple platforms.
