today the world’s first energy-automated Z-Wave sensor was released.
It’s powered by solar energy only. A little solar panel is charging a small capacity inside to power the device also at night. Hence no batteries are needed at all.

The internal battery management makes sure that the capacity is never fully discharged but keeps enough energy for emergency actions in case of heavy wind.

Z_Weather is a combining several environmental related sensor. All these sensor values can be reported a central Z_Wave controller The following values are available:

– Air temperature
– ambient light
– relative humidity
– wind speed
– air pressure
– dew point

The device furthermore estimated the solar and the wind energy to be harvested on the position the sensor is mounted. The total solar energy is measured in KwH but refers to a standard 1 square meter panel positioned at the place of the sensor.

The wind energy is counted in total number of rotations, however the measured energy count only used ever 8th rotation of the wind mill.

The internal energy management makes sure that there is always enough energy for the essential operations, wind alarm. The energy management will change the wakeup time on demand, the time where the device will transmit the other sensor values such as temperature etc. to the central controller.

The wakeup interval can change between 5 minute and 1..2 hours. On a morning of a long night in winder time it may even reach 5 hours as an extreme. The button operation will be deactivated as soon as the energy level falls below 30 %

Hi Chris,

I am doing Smart Home with my Fibaro Home Center 2 and am wondering, if Fibaro is already supporting the Z-Weather. Do you know other controllers that already work with Z-Weather and maybe you have some information about if Fibaro is working on implementing the Z-Weather?

Thanks a lot in advance

Hey Alex,

currently Z-weather is not supported in Fibaro HCL / HC2 – sorry!
Fibaro statement: in the next Hofixes it will be implemented.
On Devolo Home Control and in Z-Way (RaZberry) is Z-weather 100% compatible.
Also Zipato will implement Z-weather in the coming next weeks.

Is there any technical datasheet about this product?

I figured out how to change the default BASIC_SET values sent by the z-weather when a threshold is triggered. (As my awning was moving in the wrong direction when there was too much wind.)

Like always it is simple when you know how. The z-weather follows the z-wave standards and there was no need for a technical or developer manual from the manufacturer (although I asked, based on experiences with other brands).

For other users facing the same issue/question, below an example how I did this with z-way (Razberry).
At this moment of writing the command class (ASSOCIATION_COMMAND_CONFIGURATION), needed to change the default BASIC_SET value, is not (yet) implemented in the z-way user interface or expert interface.
But you can use the API of the z-way software to send the desired configuration commands through entering a line in a internet browser.

In the example below the z-wave ID# of the z-weather is 44 (replace with you own id#) the z-wave ID# of the awning (sunscreen) is 22 (replace with you own id#).
An association have to be setup in the normal way between group 2 (too much wind) of the z-weather and node 22 (the awning/shutter module).
To change the (default 00) BASIC_SET value to 255 I entered the following in my browser: (using z-way as controller!)

http://Z-wayIp:8083/JS/Run/zway.SendData(44,[0x9b,3,2,22,3,32,1,255])

With the default setting changed I am able to use the z-weather without the presence of an online z-wave controller and keeping my awning at one piece when there is too much wind. That was the reason for buying the z-weather.

I hope the information above can help other home automation enthusiasts with a z-weather too.
