Question: Venetian blinds mode #17

Closed CHTHSCH closed 4 years ago

CHTHSCH commented 5 years ago

Does your plug-in support roller shutters (Rollläden) only or also venetian blinds (Jalousien) where you can control the position of the lamellas as well?

steilerDev commented 5 years ago

Currently tilting the lamellas is not supported for rollershutters. How is the tilt angle exposed within openHAB? is it s number representing degrees of an angle?

CHTHSCH commented 5 years ago

I will move over to openHAB to control my blinds (Jalousien) two weeks from now. After that I will now and will let you know. I am using FIBARO Roller Shutters (2 & 3). The control of the lamellas is defined by the time they need to fully rotate. There should be two items types in openHAB, a roller shutter item, that controls the movement up/down and a dimmer item, that controls the lamellas.

CHTHSCH commented 5 years ago

I am using FIBARO Roller Shutter 2 and 3. The RS2 is defined as blinds_control, also for the lamellas and the RS3 as switch_dimmer, also for the lamellas

It is represented as a number (I would say % rather than angle) that determines one full turn (0° - 180°, or in my case 0°-90°)

CHTHSCH commented 5 years ago

Update: In the new SNAPSHOT, the RS3 is also represented as blinds_control. Lamellas are controlled by a second item

steilerDev commented 5 years ago

I checked with the HomeKit specification and it states for vertical and horizontal tilting of WindowCovering the following:

The characteristics describes the current angle of vertical slats for accessories such as windows, fans, portable heater/cooler etc. This characteristics takes values between -90 and 90. A value of 0 indicates that the slats are rotated to be fully open. A value of -90 indicates that the slats are rotated all the way in a direction where the user-facing edge is to the left of the window-facing edge.

Therefore, when I implement this feature, I would expect OpenHAB to provide and understand a value of -90 to 90.

CHTHSCH commented 5 years ago

I will check on Sunday again and provide some feedback. At the moment I am setting the angle of the blinds with a setpoint between 0 and 100.

CHTHSCH commented 5 years ago

The FIBARO Rollershutter 2/3 use two channels, one for the up/down and a second one for the angle of the lamellas.

CHTHSCH commented 5 years ago

The lamellas in openHAB have values between 0 and 100, which would correspond to -90 to 90. Perhaps a parameter is required, that would map this accordingly. Also openHAB allows the percentages to be reversed, which would also call for a parameter to configure the interface.

steilerDev commented 4 years ago

My latest commit (3c65977) adds this feature. I also have added a parameter to map the range from -90/90 to 0/100 (or any other range, fitting your use case).

Feel free to test the feature, I will hopefully publish my next release to npm very soon (I want to close all open issues first).
