I’m using home assistant, with mqtt which acts for many things and I get notification in different way depending the needs. Could be home assistant app or telegram or lighting up some light or sending voice messages to a speaker. All notifications are triggered by automations looking at states. Haven’t done it but automation could be re launched automatically until (for exemple) I press a button or responding to telegram message

And if that’s doesn’t work, message me and we will try to solve this out

Have you tried a Factory reset?

Not the answer you are waiting but there is something wrong with your shield, I have a 2015 and 2019 Shield and both are just very good even if the first one has nearly 10 years

On your Xiaomi first time you launched app, you can determine wether you always allow or allow on prompt (but you should still be able to manage that setting afterwards). You also need to disable battery optimization for that app and set app to be able to auto launch in background. This is at least what I do with my home assistant app to determine GPS location in background (app record every 15mn) and no issues with battery draining.

Don’t have particular case to recommend as the one I have has been printed but get one where you can add an SSD. SD card are not well suited for home assistant due to the amount of overwriting.

So pc is consuming 13W, this is with one nvme + one SSD, pic at 30w for a few seconds at boot.

Curious, might have same machine but do consume a bit more, do you have one SSD + one nvme?

It is a beelink mini s12 pro https://www.bee-link.com/beelink-mini-s12-pro-n100-mini-pc-clone-1

Do also have a n100 processor running proxmox with 3 VM. Can’t try right now but can come back in a few days to let you know how much power it draws
