KNX/EIB Door actuator and blind at the same time

[MikeMelga]

Hi.

I need some help.

I have a Gira fingerprint reader that is connected to a switching actuator and to a KNX binary input.

When I lay my finger it switches the binary input on and off with no problem.

The problem is that I don't know how to implement this:

I have an external door which has an electric lock and has an external blind.
What I want to do is: when I lay my finger the blind rises and the door unlocks for x time.

I've created a group with the binary input, blind actuator and electric lock actuator. The problem is that the blind raises and lowers whenever I lay my finger.

If the blind is raised I only want for the door to unlock.

How can I do this?

Thanks

Does your binary input has any kind of logic? Or are there lock and state objects?

If I understood you correctly, you could use the state of the blind to open the door for x minutes. During that time you also lock the blind. After the x minutes the door is closed and that unlocks the blind which moves down.

finger on fingerprint -> move blind up
blind is up -> open the door for x minutes
door is open -> blind is locked
the x minutes are over -> door is closed -> blind is unlocked -> blind move down

Did you know this this configuration is not for outdoor use?

@2ndsky,

I guess my binary input does not support any logic (I'll check later) but I do have an ABB LMS1.1 logic module, if needed.

All I need is that when I lay my fingerprint two things happen:

- Rise the blind
- Open the door for x minutes

If the blind is already up... it will only open the door.

It would be like sending the 'UP' command always for the blind.

Also...I do not want the blind to be shut after the x minutes. It stays open.


@division,

I probably did not explain correctly: I have the fingerprint connected to a switching actuator from the door communication bus. That actuator is then connected to a KNX binary input.

Ok... Great... thats the right way.

The up command to a normal blind actuator is just a one (or zero, I don't remember) to the move object. Therefor if you use the right communication object of your actuator that should work. Can you give me the vendor and the model of your blind actuator? For some blind actuators there is the possiblity to put them to a defined position if they receive a one on a boolean input group address.

@2ndsky,

The blind actuator is a Gira 1038 00.
The binary input is an ABB BE/S8.20.1

What about if I set the binary input to something like the picture?

If it always sends the ON command... I guess it could work, no?

[2ndsky]

You can just try, I'm not 100% sure. You can also look at the sun object of the blind actuator. Set this with your binary input and give the upper most position as sun position. Then the blind will open when you set sun=1.

[MikeMelga]

Will try that also.

Thanks!

Ok.....my solution worked.

I only had to change 'ON' to 'OFF' because it seems that OFF raises the blind.
Great. Problem solved.


Now that I had a taste of this... I will try other things

For example: I have another fingerprint reader that I use to arm/disarm the alarm. Together with the 'arm' command I also lower all the blinds and power off some of outlets. However... this fingerprint reader is near to a door with a blind.

How can I add a delay for that particular blind?

For example: I arm the alarm and it lowers all the blinds except that one near... which lowers 30 seconds later.

How can I do that?

Thanks again!!
