1/2/23 is the group address that is bound to the “dimming” functionality of the KNX switch. I assume that the problem is “current dimming value” vs. “new dimming value”.
Do I have to create a rule in order to dim my Hue lamps with KNX switches? Or is there another, smarter way?
Which KNX switch do you have? I have the MDT glass switch and unfortunately i can’t change the way the messages are sent.
The dimming to dark is aborted after a short reduction of the brightness. As long as i keep the button pressed the brightness keeps its value but as soon as i release the button the brightness gets set to 100% again.
I dont understand who request the 100% again…
However if i configure the glass switch to send absolute values there is no problem and the brightness keeps constant.
I have a Gira Tastsensor 3. The switch is set to relative dimming. But I had to change its behavior:
The switch is sending dimming telegrams every 200 ms, as long as the button is pressed. I had to reduce the dimming steps down to 6%. With these changes I am able to dim the Hue lamps nice and smoothly.
As far as I remember, the default dimming behavior is to send a start and a stop telegram. That did not work with the hue lamps.
this is a old topic
I am using Openhab 3 to control a Dimmer (Philips HUE) with an MDT Glastaster (KNX).
I´m using a dimmer Control Channel with a rule. This works, but it is not perfect.
Does the KNX Binding 3.0 support Start/Stop Commands by adding ss at the end of the Group Adress? {knx=“3.007:2/0/1ss”}
