in my migration process from Raspberry Pi4 to Synology DS918+ as Docker install I managed to port everything working so far. Home Assitant (Docker), Mosquitto Broker (Docker) and Conbee II via USB (for Zigbee) utilizing DeConz (Docker). Octoprint is perfectly integrated as well as Wake On Lan.
The only thing missing is RPC Shutdown. Since I do not have the Add-On Store (no supervisor) what would be the best / cleanest / simplest … … option to reactive that function from HA?
