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.

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.

BRESSER Climate Monitor Thermo-Hygrometer DCF 3-piece Set
Bedroom, kitchen, study, children's bedroom: the BRESSER Climate Monitor thermometer/hygrometer DCF three-piece set shows current air conditions at three individual locations. It's important that the temperature and humidity in indoor spaces are balanced for us to feel healthy and well. If the air is too humid for a prolonged period of time, there is a risk of harmful mould developing. Conversely, if the air is too dry, we can quickly experience discomfort. This is particularly noticeable on cold days after prolonged exposure to overheated air. With the thermometer/hygrometer monitor, you can keep a close eye on the indoor climate and give a boost to your health and wellbeing. Thermometer/hygrometer with indoor climate display for added comfort The handy temperature and humidity gauge shows you accurate measured values on a clear and organised display. But sometimes, all you need is the answer to a quick question: do I need to ventilate, or keep the windows closed? The coloured indoor climate/comfort indicator will show you at a glance how the indoor air is currently doing. Is the arrow in the green area? Then the humidity and indoor temperature are both in the green area as well. Red indicates that the air is too dry, while blue indicates humid air - time to act! In addition, the thermometer/hygrometer also gives you the current time on the screen. Keep track of the time: the DCF time signal automatically adjusts the integrated clock from summer to winter time and vice versa. You can also view the date with a simple press of the button. With the BRESSER Climate Monitor thermometer/hygrometer DCF three-piece set, you benefit from three handy assistants to help keep up that feel-good indoor climate. PLEASE NOTE: This device receives the DCF time signal (Central European Time). However, you can easily adjust the time display to different time zones using the offset function.

BRESSER MeteoChamp 7-in-1 HD Wi-Fi Weather Station with Various Display Modes
What is the weather doing? The BRESSER MeteoChamp 7-in-1 HD Wi-Fi Weather Station will show you everything that you need to answer this question. The dynamic 17.8 cm (7-inch) HD TFT colour screen displays the measurements from the two included sensors in a range of different display modes. With a simple button press, you can view the weather data that you need: the home screen with the basic data and a reliable weather forecast, the detailed view with more data including maximum and minimum values and trends, or the overview screen with the temperature and air pressure. And for passionate weather enthusiasts, the Wi-Fi weather station can also display historical data. The data protocol delivers detailed measurements at intervals of 5, 10 or 30 minutes – all of which can be exported via USB for further analysis on your PC. All max/min values for the past day can also be displayed on the Wi-Fi weather station with a simple button press. You can also view a history graph to analyse the recent trends in the weather. Solar weather station with 7-in-1 sensor and thermo-hygro wireless sensor The MeteoChamp Weather Station comes with two feature-packed outdoor sensors: one 7-in-1 sensor and one wireless thermo-hygro sensor.The 7-in-1 wireless sensor reliably measures the outdoor temperature, humidity, wind speed, wind direction, rainfall, UV level and light intensity. And what’s more, this multi-sensor with a large solar panel is powered by solar power. The measuring device needs about 4 hours of direct sunlight (100,000 lux) a day. There isn’t much sun around? Simply insert 3 AA batteries as a back-up during installation and they will take care of the power supply. The thermo-hygro wireless sensor is responsible for indoors. Because the climate there influences our well-being just as much as it does outside. That's why in addition to the built-in hygro-thermo sensor inside the base station this wireless thermo-hygro sensor measures the indoor temperature and humidity in an additional room. This way you can check in a flash whether the air in the bathroom is dry enough or the temperature in the children's room is pleasant - and give mould as well as excessively dry air no chance. Perfectly networked – share measurements from your Wi-Fi weather station In the age of the Internet, we want to be able to access our local weather data remotely and share it with others. The solar weather station comes with a Wi-Fi function that allows you to do just that – on up to 3 weather platforms. The Wi-Fi weather station features native support for the popular weather services ProWeatherLive, Weather Underground and Weathercloud, which can be configured in a few simple steps. If you prefer to use another platform such as the German-language portal AWEKAS, you can also connect your weather station to your desired provider. And if you have a smart home, the Wi-Fi weather station can be connected directly to your smart home system with our partner AWEKAS. For more information, visit the following link: https://www.awekas.at/for2/index.php?thread/17080-software-api-stations-api-beschreibung-beta/ The weather station also has another smart feature to ensure that you have plenty of time to get ready on frosty mornings: an ice/frost alarm. This makes the built-in alarm go off 30 minutes earlier when the outdoor temperature drops below -3 °C. The solar weather station also has an individually configurable weather alarm, which notifies you when the wind speed, rainfall or other readings exceed or drop below your preset limits. Keep track of the weather with the comprehensive measurements and display options on the BRESSER MeteoChamp 7-in-1 HD Wi-Fi Weather Station.
