Thank you, I am going to do all the above, “Remote RPI system monitor” looks really good.
I can’t use Wake-on-Lan, because the Pi is on WiFi, but I have another solution for that with the Sonoff Micro (smart USB power).
So here’s the plan for one of RPIs which I want to turn on and turn off alongside a PC.
PC Turns off:
Sends MQTT -> Node Red Sends SSH to Pi to shut down -> Configurable ping node starts and pings Pi for 60 seconds -> after ping fails, Sonoff Micro kills USB power.
PC Turns on:
sends MQTT -> Turn on Sonoff Micro
USB power is restored, Pi boots with PC
This particular one is all because I have a media / gaming PC in the living room, the Dongles for a mini keyboard, Game Controllers and Bluetooth are just out of range and keep dropping out.
So I put all the dongles in pi and used “VirtualHere” on the Pi, and I can have the Pi Closer, which all works great.
The issue is that whenever the PC wakes up from sleep or hibernate the VirtualHere client and Pi server fall over each other and both need to be restarted. Plus there’s no point in the Pi being on for no reason
