Quick explanation

Understand in 2 minutes

From sensor to automatic ventilation control – briefly explained.

Easy as 1-2-3

Ready in three steps

1

Set up Shelly

Connect Shelly H&T Gen3 as sensor and Shelly Plus 1 as relay to your WiFi. Done in minutes – no soldering, no coding.

2

Configure location

Create a location, link sensors and set thresholds for dew point difference, minimum runtime and max runtime.

3

Automatic ventilation

The app detects when outdoor air is drier than indoor air and automatically switches the ventilation on and off via Shelly.

Why Breeqo Taupunkt?

Why invest €1,500 in hardware when the intelligence fits in your smartphone?

Traditional dew point controllers cost €800–2,500 plus installation by an electrician. Breeqo Taupunkt starts at €0 – with standard hardware from €35 that you set up yourself in 10 minutes.

Traditional control

The "Old World"

  • Expensive: €800 – 2,500
  • Hardware lock-in: Only manufacturer's sensors
  • Rigid: Once installed, never updated
  • Complex: Wall drilling & wiring required

Your app

The "SaaS World"

  • Minimal start: From €0 / affordable subscription
  • Free choice: Compatible with standard sensors
  • Smart: Cloud updates & weather forecasts
  • Plug & Play: Simply connect to your WiFi

No more overpriced hardware

Why pay €150 for a replacement sensor when a €15 sensor from the smart home market delivers the same precision?

Intelligence over switches

Conventional devices only check indoor vs. outdoor. Our logic includes the weather forecast so you don't ventilate when it's going to rain in an hour.

Control in your pocket

Instead of walking to a box in the basement, you see live dehumidification and mold risk on your dashboard – wherever you are.

FAQ

What is dew point control and how does it work?

+

Dew point control compares the dew point of indoor air with outdoor air. The dew point is the temperature at which air releases its moisture as condensation. If the outdoor dew point is lower than the indoor dew point, outdoor air can absorb moisture – the ventilation is automatically turned on. This effectively dehumidifies the basement without bringing in warm, humid air.

What sensors do I need for automatic basement ventilation?

+

You need at least one indoor temperature and humidity sensor (e.g. Shelly H&T Gen3, approx. €17–20) and a switching actuator for the ventilation (e.g. Shelly Plus 1, approx. €12–15). The app automatically gets outdoor values from weather data. All devices connect via WiFi – no cables, no soldering required.

How much does a dew point ventilation controller cost?

+

With Breeqo Taupunkt you start at €0 on the free plan (1 location, 2 sensors, 1 actuator). Hardware costs under €40 one-time (Shelly H&T + Shelly Plus 1). For comparison: traditional dew point controllers cost €800–2,500 plus installation by an electrician.

Can I use my existing Shelly sensors?

+

Yes. Breeqo Taupunkt is compatible with Shelly and SwitchBot. If you already own Shelly or SwitchBot sensors, you can connect them directly – without additional hardware.

How does dew point control prevent mold in the basement?

+

Mold develops when relative humidity exceeds 70% and moisture condenses on cold walls. Dew point control automatically detects when outdoor air is drier than indoor air and ventilates specifically. This continuously removes moisture before mold can develop – 24/7, without manual intervention.

Does the app work without internet?

+

Shelly devices continue to work locally on WiFi even if the internet connection briefly drops. The app needs internet for the dashboard, weather data and notifications. The control logic ensures that the last known state is maintained during connection loss.
