For now, I use 3 devices:
- The RoofWindow itself, which is a Blinds Percentage Inverted device
- RoofWindow RainSensor
- RoofWindow RainSensor Alarm
The rainsensor devices go "On" when it is raining outside and the roof window is open, the roof window then closes automatically. These rainsensor devices go "off" after 2minutes, so they do not stay "On" for as long as it rains.
I'm still figuring out what the alarm devices are doing exactly. They are switching Off together with the rainsensor device. Probably to be used to trigger other z-wave devices as well via the group function. I must admit that I only recently started with z-wave and I did not read the f*cking manual

One thing I also didn't get to work is to operate the roof window from Domoticz as well as with the remote that came with the roof window the Fakro ZWP10). Probably I have to add the ZWP10 as secondary controller or something. Seems that I do have to read that manual.
If anybody has questions about this roof window (or tips on how to add the remote), let me know!
