Hi farmio, thanks for your input, I didn't think about that when I changed the mode to parallel (and to be honest I mostly copied your code for the dimming part without thinking too much about it :p). The goal of parallel was to avoid missing any light state change in the unlikely case that the process would still be running when a light state/attribute changes again quickly.
I guess that I will need to change it to restart to avoid the dim to go full scale up or down every time :-D
You'd need some kind of global variable (or even better, automation scoped) that you can set on dimm-start and unset on end. Then check for it on every repeat. That way parallel would work.
With restart mode, intermittent status value updates would cancel your repeat - and thus the dimming.
correct, every state change of the light entity (including the one induced by each step of dimming) will stop the process. As far as I can see there is no way to create global variables in automations/blueprints at the moment right ? The only workaround that I see is to manually create a toggle helper for each light, reference it as an input, and use it to store the beginning/end of the dim process. Any other idea ?
I modified the code to use an external Helper entity to catch the "stop" telegram. I guess that there are no other solutions until HA supports global variables for automations :/
Thank you very much for this script! I really appreciate it and it works almost perfectly :)
Unfortunately I'm having the strange issue that somehow the stop telegram when releasing the relativ dimming button does not get caught - but only when dimming up. I even checked it with looking at the helper entity state: For dimming down it reliably switches on-off whenever the dim button gets released. But for dimming up it does nothing and the dimming continues.
I also checked the group monitor for the dim group address and i could verify that the stop telegram gets sent but the increasing of the brightness continues:
There are no related error in the HA logs from what i can say. And I also triple checked that there is no other entity interfering with the dim address.
Do you have any idea what I could do wrong or where to change something to make it work? Any help is appreciated
When dimming down immediately after "stopping" a dimming up process, the light flickers, because the dimming down seems to "fight" agains the dimming up. Maybe that could also give a indication of where the problem relies.
You'd need to check the trigger data for data in (0, 8)
instead of data == 0
in the stop branch (Line 319) (pseudo code - not sure if this works as such in jinja).
exact, I changed it the easy way :-) should work now
Thank you both for the super fast reply. I can confirm that the updated script now works perfectly well. 🙌🙏
Hey,
i do have MDT lightswitches which have a "Color Temp (Tunable White)" mode. This uses DPT 3.007 for dimming as well as for the color temp. Is there any way to use this with your blueprint?
Hi Daniel, I doubt that it's gonna work with the actual version of the blueprint, but it's probably possible to code that. To be honest I won't be able to implement this myself since I don't have such hardware to test/debug and really not enough free time atm, sorry
Hi, thanks a lot for this blueprint, it solved my KNX-Hue problem ;-)
In my setup with MDT glass switches, I don't use continuous dimming, but the "send value" setting with discrete dim values. I'm not sure if it was because of this that the current dim value didn't get sent back to the switch when switching to the next value. By adding the knx.send function at the end of the "BRIGHTNESS command", I got it working.
- service: knx.send
data:
address: "{{ value_state_address }}"
payload:
- "{{ state_attr(light_entity, 'brightness') | int(default=0) }}"
Hi ptobler,
Why don't you use the "Brightness state group address" from the blueprint which is doing exactly that ? It would then also send the new brightness value if you dim your light via the HA interface, so your MDT switch is always in sync ;-)
Hey @kalhimeo ,
thanks for this awesome blueprint.
I have it running for a while but noticed an issue maybe related to the last HA update (2023.11.2) or the latest zigbee2mqtt update.
When turing a zigbee light off, the brightness
is now null
instead of not defined. This leads to an issue where the 0 brightness value was not send to KNX.
Temporarily solved this by changing this line to
- "{{ trigger.to_state.attributes.brightness or 0 }}"

Hi sti0, thanks for reporting this bug. I think that they changed something in HA recently about that since I now have the same bug with my Hue lights. I will have a new version to fix that soon. I am also working on a "tunable white" support so I will release both updates together when ready
Hi 👋!
If you use
mode: parallel
, how do you end therepeat:
loop for relative dimming (line 303) when a stop telegram was received?On my blueprint I use
mode: restart
for that.
