Terncy knob does not send ZHA events

I have a zigbee terncy dial knob. I few month ago it used to send ZHA-events when the button was pressed or the dial was turned. But with a HA update, it stopped to send Zha events. Now I don’t see any event in the developer tools.
How can I debug this problem? Is there a chance to switch on a log to trace the way of events?
