I have now been in contact with the maintainer of Calimero the library that the KNX addon is using, he has implemented a fix in the latest source in order to fix this.

When pushing a lot of messages through a Serial FT1.2 connection at the same tim… e only a few will actually go through to the network.
I.e. when in openHAB sending OFF to a (openHAB) group the binding will send multiple KNX group commands at the same time. The debug log looks like:
```log

```
when running through a TCP connection, this was not an issue. Should calimero buffer the sending of telegrams or should the user of the library (in this case the openHAB binding)
I have setup a CI that builds the KNX addon with the latest Calimero lib here:
KNX Addon + Calimero build service status latest build
The direct link to the latest jars is here:knx-addon.bundle.zip
And it works with that build now. Without the “Force Lights” group hack.
