YAHKA crashes continouesly when using home app

See original GitHub issue

Hi there. I’m using YAHKA prefer redly to map my KNX Installation to HomeKit using iobroker and the KNX adapter. Initially, with Version 0.8.1 it worked fine. After upgrading to 0.9.2 it continuesly crashes when pressing a “button” in the home app, i.e. to switch a light. The Adapter restarts after that.

I suspected the knx adapter that was updated as well, but I have no option to downgrade, due to the knx architecture and importing projects. As well I need the multistage feature due to the knx architecture, where state and action are typically two objects.

I get this error log:
