I have a Marantz NR1506 AVR that worked just fine with OH2, using HTTP control.
But since upgrading to OH3 I can’t turn the AVR on from OpenHab. The Thing shows as Offline with:
COMMUNICATION_ERROR
IO error while connecting to AVR: java.util.concurrent.TimeoutException: Total timeout 5000 ms elapsed
shown at the head of the page. The AVR is enabled for Network Control always, and I can still ping and use the built-in web control. So it’s definitely still accessible.
What gives?
