I am on a fresh build of OH 4.0.1, not an upgrade. I am having issues with my 2 Pioneer Air Conditioners going Online and Offline every couple minutes. The debug shows endpoint unreachable when it goes offline. This is seen as a Thermostat Appliance. It does not have this issue in 3.4. In fact, if I disable it in 4.0.1 and enable it in 3.4. it stays online and works properly in 3.4. All my other Amazon connected devices work fine. Thank you
