When I received the device, I was very happy to have this POE option and so I started with a second instance of Z2M. After getting this started I tried to integrate some Zigbee devices, but interviewing failed always. So I opened a ticket and I got an answer very quickly. Everything did not help, and finally I started to try to update to e dev FW. This failed, maybe due to my PC hardware, as well. Than I got a message to get in touch with a developer, and finally the newest FW on ESP32 and ZIGBEE are flashed. Thank you Serge and Taras! Regards Christoph
