This is something I have put on two raspberry pi's I have setup for friends recently to use for basic automations. Rasoberry Pi's setup to monitor and control various sensors and Tasmota devices.
The flows simply build a little control panel for the server with some basic information and status on the services running. For somebody not familiar with Raspberry Pi, Linux, Node-RED, MQTT and more concerned with making stuff work then knowing that everything is running is gold. Having some browser tools for graceful shutdown or restarts is also a safe option.
