I’m running a Node-Red implementation on a HomeMatic box - RedMatic. I loaded the denon contrib and configured it. Seems to work well on a first view. But the next morning it was “frozen”. No function. After analyzing the network traffic I could see - there was no traffic. The Denon contrib simply didn’t send any commands out to the network. In the debug log there are entries like “send error: Error”.
Can you give me hints how to troubleshoot this?
