How Temperature Measurement Helps Save Energy

Did you know? Lowering the room temperature by just 1 degree can save up to 6 percent of energy. It's worth paying close attention when heating. With the integrated thermometer in our weather stations and thermo-hygrometers, you can always keep an eye on the current room temperature – allowing you to adjust your heating habits to save energy. Has the temperature reached a level that's comfortable for you? Then the thermostat can be turned down a bit to maintain the room temperature and save money.



Practical everyday helpers: Some models also offer a high-low temperature alarm that alerts you with a sound when your individually set temperatures are reached. Our modern Smart Home weather stations take it a step further: based on the measured values, these devices can automatically regulate your heating through an app and your existing Tuya thermostats. Saving energy can be that simple!


Why Get a Weather Station for Your Home?

Storm surges, hurricane-force winds, and heat waves – climate change is becoming increasingly noticeable. Even in Germany, we are experiencing more frequent meteorological changes. And the trend is rising!

Why is it worth having a weather station at home when weather apps are available? BRESSER's product manager for consumer electronics, Dominik Becker, answers this and other interesting questions in an interview for you.

Product information "BRESSER CO² Air Quality Monitor Smile"

Endless meetings, urgent work emails, looking after the kids, cleaning the flat… during our hectic lifestyles, it's easy to forget about regular ventilation. Even though we know better: a high CO2 concentration can affect our health and wellbeing. The BRESSER CO2 air quality monitor Smile will show you when it's time to let some fresh air into your home or office. Simply have a quick look at the intuitive LCD display to keep an eye on the CO2 concentration, temperature and humidity. You don't need to worry about remembering what constitutes a critical carbon dioxide level - the intuitive graphical display with a linear scale and smiley face will show you the quality of the air in your surroundings. The measurements are precise, with high resolution and fast

Ventilation alarm

The practical carbon dioxide alarm reminds you when you need to let in some fresh air. If the default setting is different to your ideal indoor climate, you can configure your own limit up to a maximum of 5000 ppm. The alarm function can then be activated with a simple button press. If the preset limit is exceeded, the alarm will sound at a varying intensity depending on the CO2 concentration. The display will also show a flashing arrow symbol to remind you to open the windows. 
Humidity is also an important factor, as high humidity levels can cause mould to form. You can also set your own visual alarm for this reading so that you will know whether the air in the room is too dry or too moist. If you want to see more than just the current readings, there is also a practical memory function that displays the maximum and minimum values for the last 24 hours as well as the average values from the last 15 minutes and 8 hours for carbon dioxide concentration, temperature and humidity. The device is powered by a power adapter to enable continuous operation

BRESSER ClimaTrend Hygro Indicator 3-piece Set Thermo-Hygrometer
The ideal room climate not only has positive effects on our well-being, it is also good for our health. The two critical values which determine the room climate are temperature and relative humidity.If for instance the humidity is too low the effects can be burning eyes, chapped lips as well as dry nasal mucosa, which reduces our ability to provide protection against inhaled pathogens. On the other hand, if the humidity is too high there is a risk of mould formation. This can also be prevented thanks to the indicator. With the practical 3 piece ClimaTemp Thermo Hygrometer Indicator you now have the control over the room climate in all the rooms you spend most of your time in (e.g. living room, bedroom and children's room). Next to the exact measured values for the room temperature (C°) and humidity (%) the indicator also shows in symbolic form, whether these values are within the recommended range or if there is a need for action.
