First of all say thank you to everyone posting and answering since reading dozens of posts related I have been able to make my KNX/alexa run in this OS and platform that I never handle before, specially thanks to @Udo_Hartmann who appears in many solved post which comments really helpful and maybe can help out this time as well. It was not easy but I got reasonable success so far.
At the moment I have just modeled a few components which I have simplified above since they were repetitive. Only two sort of things: lights and blinds
The target is just make the system recognize the KNX console, identify properlly every item, make them work and then link them to Alexa. Well, target accomplished so far. At this point I need to properly fix it, to make it work as I wish.
The issue comes as follows:
Blind is working in a 36 steps or pulses based. So the range of the blind goes from 0 to 36 and makes no action over 36 since it is fully closed.
In the same way appears said before in HABpanel. I can set the slide from 0 to 36 since range over 36 is useless, but the target would be teach the system the 36 position should be the 100 one instead of working with a weird range such 0-36.
At some point I think somewhere I have read this can be solved setting up max and min limits in things file, should this is the correct way. Not sure whether in the community or maybe in BK Hobby tutorials (which I found really helpful) I think I have seen it can be done.
May some of you guys help out with this?
Beyond of this, as further step I need to solve the way Alexa understand instructions. She acts to my demands but not right since when I tell her “Alexa raise the blind” she does in the oposite way and viceversa and not full but parcial move of the blind
I am aware of Alexa skill metadata configuration but I would like firstly fix the issue above, make it work properly in HABpanel and then Alexa.
Rollershutter Blind "Blind" {alexa="RangeController.rangeValue" [category="INTERIOR_BLIND", friendlyNames="@Setting.Opening", supportedRange="0:100:10", unitOfMeasure="Percent", actionMappings="Close=0,Open=100,Lower=(-10),Raise=(+10)", stateMappings="Closed=0,Open=1:100"]}
Thanks in advance.
