Z-Weather is the world’s first energy-automated Z-Wave sensor. The multi functional sensor is powered by a solar cell. Thanks to the energy management and the internal capacitor the wind sensor sends measures to the Z-Wave Controller even during the night. The built in energy manager automatically calculates and sets the wake up interval between 5 minutes (on sunny days) and 1 – 2 hours on cloudy days or at the beginning of the day. Additionally, the energy management protects against full discharging and enables continuous operation for reporting gusting wind, storm or dusk in case of emergency.

The multi functional sensor is able to capture and send different values via Z-Wave to the smart home center:

• Air temperature
• Relative humidity
• Light intensity
• Wind speed
• Air pressure
• Dew point

In addition, Z-Weather samples the energy delivered by the solar cell. The measurement is normalized to a solar cell of 1 square meter and  reported with 16% efficiency in kWh.

To  calculate  the  wind  yield,  every  eighth  rotation  is  counted  and  the  total  sum  is reported as Pulse.  

Thanks to Z-Weather you can trigger closing of the awning and blinds either by direct associated devices or scenes. Measures of the ambient light and the solar yield can be used to turn on the outdoor light at dusk time and turn the light off in the morning.  

Please notice: Before you can configure and use Z-Weather, the unit needs to be fully charged by direct sunlight for 4-6 hours. Without direct sun light, charging may take 12 hours.
