Frequently Asked Questions - Cosy Baro 35.1154.01 TFA

How to set relative atmospheric pressure?

Press and hold the SET/+ button for 5 seconds. The pressure value flashes. Use SET/+ and °C/°F/- to adjust, then wait 5 seconds to confirm.

How to change the temperature unit?

Press the °C/°F/- button to switch between degrees Celsius and degrees Fahrenheit.

What to do if the screen stays blank?

Check the polarity of the batteries. Replace them with new AAA 1.5V batteries if necessary.

How to connect the device to WeatherHub?

Open the WeatherHub app, tap Add a new sensor and scan the QR code on the back of the device. A WeatherHub gateway (not included) is required.

What is the radio transmission range?

The frequency is 868 MHz with a maximum power of 25 mW. Typical range is about 30 to 100 meters in open space, but may vary depending on the environment.

How to interpret the pressure histogram?

The histogram shows the evolution of pressure over 24 hours in 7 steps. Rising bars indicate improving weather, descending bars indicate deteriorating weather. The 0h level corresponds to the current pressure.

What is the humidity accuracy?

The accuracy is ±5% between 10% and 90% RH, and ±7.5% outside this range.

How to clean the device?

Use a soft, damp cloth. Do not use solvents or abrasive products.

What to do in case of battery leakage?

Wear protective gloves and goggles. Carefully remove the batteries and clean the compartment. Dispose of used batteries according to regulations.

Where can I find the EU declaration of conformity?

The EU declaration of conformity is available on the website www.tfa-dostmann.de by entering the item number 35.1154.

6. Getting started

• Open the battery compartment and insert two new AAA 1.5 V batteries, polarity as illustrated.
• All segments will be displayed briefly and subsequently the number and version number of the software and the absolute actual atmospheric pressure measured by the sensor.
  • The indoor temperature and humidity appear on the display.
  • The device is ready for use.

7. Settings

7.1 Atmospheric pressure setting

• The barometer has to be adjusted first to your local altitude.
• Ask for the current relative atmospheric pressure of your home area (local weather service, www).
• Press and hold the SET/+ button for 5 seconds to enter the setting mode. The pressure value (default 1013 hPa) flashes.
• Press the SET/+ and °C/°F/- button to set the relative atmospheric pressure.
• Press and hold the buttons for fast mode.
• Wait 5 seconds until the display returns to normal mode to confirm the setting.

7.2 Temperature unit setting

• Press the °C/°F/- button to change between °C (Celsius) or °F (Fahrenheit) as temperature unit.

8. Pressure history graph of the last 24 hours

- The bar chart indicates the air pressure history trend over the last 24 hours in 7 steps, 0h, -3h, -6h, -9h, -12h, -18h, and -24h.

COSY BARO – Barometer-thermometer-hygrometer GB

• The "Oh" in the middle of this scale is equal to the current pressure and each change (± 2, ± 4, ± 6) represents how high or low in "hPa" the past pressure was compared to the current pressure.
• If the bars are rising it means that the weather is getting better due to the increase of air pressure. If the bars go down, it means the air pressure has dropped and the weather is expected to get worse from the present time "Oh".

9. Live healthier by controlling the temperature and humidity

• Checking indoor temperature and humidity can help to achieve a comfortable and healthy living environment and may even save you money on heating costs.
• Excessive humidity indoors promotes the formation of mould. But air that is too dry is also bad for your health.
• Ideally, the indoor temperature should be between 18^ - 22^ and the relative humidity between 40 - 60% .

10. Setting of the WeatherHub connection (only in conjunction with the WeatherHub system)

- You can connect the station with the WeatherHub System gateway (not included). Your data will be transmitted wirelessly through the gateway and the Internet directly to a server.

• Once connected, you can monitor the values measured at your home on your smartphone and use numerous additional functions.
• Open the WeatherHub App and the overview will be displayed. Tap "Add new sensor" and scan the QR code on the back of the station.
• For more information and a detailed description, go to www.tfa-dostmann.de/weatherhub
