After more than 12 months of working as expected, it dawned on me how good this device was, so I bought a second one just in case..... Just have to master the offline backup and restore process and the solution stands up really well. For me, powering the device via POE with the option of USB is really flexible, and having WiFi as well helped troubleshoot issues as I can take this device (the coordinator) out to the router or end device that I am having an issue with to speed up the diagnosis using HA. Well done and thank you!
