For hobby meteorologists: Z-Weather on the Devolo-Home-Control

by crissxcross2. September 2016

The Z-Weather multi-sensor also functions with the Devolo-Home-Control System. Unlike Fibaro and Co, data concerning weather can even be graphed in diagrams and this is how it all looks in the WebUI:

We already talked about the energy-self-sufficient weather sensor Z-Weather multiple times: Z-Weather in the test, Script for Z-Weather under Fibaro HC2, Netatmo vs. Z-Weather, … and so on.

Thanks to solar energy, this manages to go without additional power supply and provides diverse data about the weather to the user. It is now possible to integrate the weather sensor into the Devolo-Home-Control Center and to use data concerning weather for the performing of certain rules. In the following we are going to show you, how easy the integration and usage work:

Preparation:

Before the logging on to Z-Weather can be performed, following steps have to be followed:

  • Z-Weather comes unmounted; the montage is conceivably easy though – the 4 rotor blades are mounted onto the sensor with the 8 enclosed screws and nuts – Done.
  • Before going into the teaching mode, the sensor should be charged for about 6 hours, which means it should be laid into the sun, in order to receive enough power for the inclusion process.
  • In order to receive reliable measured value, the montage should not be done in direct insolation, if possible, since the directly illuminated sensor would then deliver divergent (higher) temperatures from 10-15 degrees. Even in the shadow the sensor will charge sufficiently in order to be able to last the whole day, especially as the transmission intervals are being adjusted to the capacity of the intern capacitor. This way the intervals at night are prolonged to up to 2 hours or on dark winter days to up to 5 hours. However, the Z-Weather will always have enough power to directly pass on “extreme” wind conditions. (The limit can be defined in the parameters.)
  • The direction of the mounted solar panel to the south is not absolutely necessary. A bracket for the montage of the pole is unfortunately missing in the extent of delivery.

Inclusion:

The sensor can be logged into the Devolo-user-interface without any problems. For this purpose you choose “(+) Plus – Symbol” -> Other devices -> Z-Wave device from the list of devices. The teaching mode will be started, you have to push the button on the bottom of your Z-Weather 3x within 1,5 seconds.

Tip: There is a small button with following functions underneath the sensor: Push 1x: NIF (wake up) / 3x within 1,5 seconds – Inclusion/Exclusion / push for more than 2 seconds: return to factory settings

After the inclusion is done, the device will appear in the overview and can be used directly.

Following information are gathered and passed on to the Devolo-center:

Daten

  • Humidity
  • Temperature
  • Brightness
  • Wind speed (unfortunately not the wind direction)
  • Air pressure
  • Dew point
  • Own battery status

… and the arising solar energy at the installation site / resp. possibly achievable electric energy through photovoltaic-modules. The latter is obviously unrealistic, if the sensor was mounted in shadow as described at the beginning. The gathered data is neatly displayed in the overview of devices resp. the daily statistic.

 

 

 

 

 

 

Statistik

In case of bad weather (or by day at insufficient brightness), resp. at night, Z-Weather will turn off automatically, resp. into the power-saving-mode. If this happens, the transmission intervals will be enhanced, from 5 minutes to up to 5 hours (at night), and thanks to the “Wake-Up-Function” only “Extreme values”, which will then be able to perform certain actions, will be transferred.

Example of Use:

At this time there are unfortunately not that many scenarios that can be performed with the combination Z-Weather and Devolo, since components like shutter-/awning control are missing. Though, the measurement “Brightness” can be useful to the user for the light control. This way, e.g. a rule can be created, which turns the light on at the predefined brightness. This far, you either had to work with time rules, which then had to be laboriously adjusted to the twilight during summer and winter – or with a motion sensor, which in inside areas is somewhat unreliable in case of closed awnings or a lack of movements.

An example for a rule would be e.g. “If the outside brightness goes below 21%, turn on the light in the hallway.” The complete would then look like this:

example rules

You can either limit this temporally (light on for x-hours) or turn it off via time control (e.g. 0:00 o’clock). Likewise, a combination with several lamps or other conditions is also imaginable.

Furthermore, you could set up a warning via email or massage in case of extreme values to, as the circumstances require, take actions, other than that you can also be warned after getting up, if the temperatures are close to the freezing point. This way you are pre-warned and can start your way to work safely.

Due to a lack of further Devolo-components there are not any more additional functions yet, though, Z-Weather convinces in combination with the Devolo-Home-Control, thanks to a reliable inclusion, smooth operation and the delivered data, which at least please the hobby meteorologists among us.
