KNX and Flows

Questions & Help
1

I have a problem with usage of KNX in a flow.
I want to make a Flow to close (4) the shutters , and set status (6) of lights.

The problem is that the behaviour is random. Some times 1 or 2 shutters wont close and other time the light doens’t work. I added delays between the commands. But that doesn’t seem to help.

For reference i had setup a Home Assistant. And there it all works. Like expected.

Any idea what is the cause ?

Welcome @Jan_De_Schepper ,
for those readers, who do not a) know your configuration or b) have had exactly the same experience, your post is more like a quiz than a demand for help.
So please tell us more about:

  • your type of home
  • the App(s) you are using
  • the KNX devices in question
  • what you wanted the flow to do
  • what the flow did or did not
  • if possible about the circumstances and conditions, when it did not work as expected and why you think the shutters should close or the lights should turn on or off
    And show us
  • your flow that does not work as expected

As I do not know your experience with flows with other devices, my first suspect would be , that you misunderstand the concept of When… and And… cards. But of course sometimes the apps do something strange, which would be something to be told to the support team of the relevant app.

Hi,

I have a Homey Pro 2023 ,
I only use the KNX integration app in these flows.
I have light an shutters in configured in homey , which do work from within homey.
I have build a flow (which is started manualy) with only Then rules , to close some shutters en set some light on and off. Some kind of evening sphere.

The problem is that de flow is working , but it drop some commands to KNX at a random base.
Sometimes the shutter doesn’t go down onother time the lights are not set. When I re-run than sometimes it works.

I think you are not the only one with problems, see Homey 10.2.1 and KNX-IP interface not reachable - #14 by Andrea_Marchisi
