KNX/EIB Pushbutton dimming

[rgiglietto]

Hallo Alles,
is it possible with pushbutton with long operation to dim up and then down without leaving button? only one press.
I thought it was possible but I forget how.
Normally with only one press you may reach max or min level but you need to press twice to pass from max to min.

Yes, but the sensor needs to supports this function.

Merten

Is it possible to upgrade firmware in Merten devices? How?

Is it possible to upgrade firmware in Merten devices?

It's almost impossible to answer such a question without knowing the exact type of device.
As saft6luck said, the application needs to differentiate between a short push and a long push
Usually, using the latest version of the application would do the trick.
Of course, in the application, you have to select "dimmer" not "switch"

I'm using Merten's series 6222xx 6227xx, works great

More details

I would ask to give a look to these pictures.
I think problem is: Dimming cannot switch channel in both ways, isn't it?
devices are MTN649315 universal dimmer 4x150w and MTN670802 Push-button interface, 2-gang plus both from Schneider electric

Hi,
You have good devices and your setup is almost correct, just some details need to be tuned.

I think problem is: Dimming cannot switch channel in both ways, isn't it?

I've attached a sample setup, with Merten devices, almost the same as yours. Mind the red lines.

from Schneider electric

I'm still a loyal Merten customer, I'm very happy with their excellent Tech Sup.
Why Schneider ? to have the application in french ? I'm happy with the english version.
I'll not forget that they have changed the manufacturer ID to avoid that people could load the new application in old Merten devices

I wish you a Happy New Year, a year without bugs

Merten vs Schneider

Here in Italy Merten is no more dealt
I have no contact with Merten directly.
schneider support has replied it is impossible to set devices in the way we are talking in this thread.
I ask to the person who asked me about this problem to put dimming can switch on and off, as we both were arguing and I will send the result as soon as I can.
Thanks to you Warichet and all contributors.
Let's stay in contact, will you?

No problem, look here

No problem, look here de-merten-infoline@de.schneider-electric.com

The support is supposed to know what they are talking about

Did you have a look at the above screenshots ?
Do you think it is working for me ? (although I didn't use exactly the same models as you)
If yes, have a closer look at the screenshots and try to duplicate the settings.

Of utmost importance are:
- the parameters of the dimmer (tuut5) and
- the parameters of the PB (tuut6)

Can you do it ?

Status

Hello,
it seems that on and off in dimming section is an option already tested.
I see that project has something wrong in my opinion about status.
Push botton needs to know about status of dimmer channel?
In picture you can see status with input object. What about this?
