The Bresser 8-day 4CAST XL 7-in-1 Wi-Fi weather station with a solar-powered sensor features a modern design with a huge 48.3cm (19”) wide-angle colour screen for displaying your meteorological data. Ideal for offices, schools and plant nurseries – the base station is perfect for providing an overview of the weather in large rooms. In addition to displaying the data from your outdoor sensor, the Wi-Fi weather station can also connect to the Internet to display forecast data from the ProWeatherLive platform, including an 8-day weather forecast with maximum/minimum temperatures and the chance of rain, as well as the local visibility and cloud cover.

Solar-powered weather station

The weather station comes with an eco-friendly 7-in-1 outdoor sensor that operates via solar power and measures the temperature, humidity, wind speed, wind direction, rainfall, UV level and light intensity. As the sensor is solar-powered, there is no need to replace any batteries. Simply align the large solar panel with the sun for seamless year-round operation. When the sun shines, the built-in rechargeable battery stores the energy to power the sensor. The data will then be displayed on your base station, which has a range of up to 150 metres.

Wi-Fi weather station with feature-packed base station

In addition to displaying the measurements from your outdoor sensor, the base station of the 8-day 4CAST XL Wi-Fi weather station also has many other functions. For example, it comes with a built-in thermo/hygro sensor which measures the ambient indoor temperature, humidity and air pressure. There is also a maximum/minimum memory – perfect for monitoring your indoor climate and preventing mildew and excessively dry air. The max/min values for outdoor, temperature, rainfall and other outdoor measurements can also be viewed on the display. In addition to weather data, the large screen has plenty of space for displaying the time, date, day of the week and moon phase. The sunrise/moonrise and sunset/moonset times are also displayed at the top of the screen.

Share your weather data and connect to your smart home

The readings from the wireless solar-powered sensor can be published on the Internet with a few simple clicks so that you can access your data remotely using the ProWeatherLive weather platform (with a web browser or the app). You can also send the measurements from your weather station to a smart home system free of charge using the german-language portal Awekas.

Solar-powered weather data: Monitor the local weather conditions with the Bresser 8-day 4CAST XL 7-in-1 Wi-Fi weather station with a solar-powered sensor.

Cold weather, hardly any sun – will the solar power continue to function?

Example: If, due to the weather conditions, the solar panel only charges for 4 hours each day and the charging current drops to 5 mA, the battery will charge 20 mAh each day. 5mA x 4hrs = 20 mAh

Even though the battery has to power the sensor for the remaining 20 hours, it will still store additional power, as the sensor only consumes a total of 4.458mAh each day out of the 20mAh charged. If the battery only charges for 4 hours at 5mA, this will provide enough power for more than 4 days of use: 20/4.458 = 4.48 days

Note: It is not possible to ship the battery fully charged. The battery should have approximately 30-40% of its capacity when installed (i.e. between 600 and 800mAh). This charge will provide enough power for 118 (600x0.88/4.458) to 158 days (800x0.88/4.458). As a result, a battery replacement will not be necessary for this sensor.
