It should work as long as it can reach the internet

I’m not really a fan of cloudflare tunnels, but I guess thats an option too

You can’t expose ports on mobile data. You can ether host the web server at home or on a vps or use something like tailscale.

You could try tunneling usb from the host into wine with usbip, but I have a feeling that this wouldn’t work

An alternative would be to boot into the bios and shut down from there

I heard of the heart rate issues in a lot of reviews, but it just works on my (and my dads) skin. Its bad that it doesnt work for everyone though. I found a stupid workaround for background heart rate monitoring, you just start the manual monitoring and then close the app on the watch, which doesnt stop the monitoring.

We only had sync issues only on my dads phone, my phone (Fairphone 5 w. CalyxOS) works just fine. The issues on his phone were fixed by an Android update a few weeks ago.

Im happy with the battery, it lasts longer than a fitbit we have.

I dont think its a perfect watch, but for <50Eur with shipping its not bad

He ordered it from the global store a few month ago, it took ~2-3 weeks to ship to germany.

Thats the only issues he told me. I also tried it for a day and didnt notice anything else it cant do, which i need. He and I only need it to show notifications/calls, track steps/heart rate, have a working alarm and show the time. I also didnt have the disconnect and notification issues, that he had.

My dad got one shipped (imported) to germany for less than 50Eur. The 3 issues he had was that the notifications didn’t work on his phone (an android update fixed that), random disconnects on some phone models and that the current alarm app only supports one alarm.

I dont know how you flashed the usb, but it seems like the installer is damaged. Try redownloading the iso, check the file hash, flash the usb drive with balena etcher and reinstall.

Did you change the partition layout in the installer?

I’m currently building a similar device, which uses miraclecast for screen sharing from a phone or laptop and jellyfin in firefox kiosk mode controlled via the jellyfin app as a idle screen. Also sending media links via kde connect is possible. I still want to implement hypnotix for tv and some kind of intigration with the streaming services of the german public brodcasters. I haven’t thought about dlna but I like the idea.

I’m also using Debian as a base but I’m using LXQT with Wayland insted if Plasma. I tested everythin on a rasberry pi 4b but it’s struggeling. I want to move everything to a rock 5c.

You could try pkexec insted of sudo. Pkexec pops up the password prompt in a window insted of prompting in the terminal.

I’m assuming you’re using the nautilus file manager. I found this post in adding right click actions to nautilus: https://askubuntu.com/questions/210192/how-can-you-add-an-item-to-the-right-click-menu-in-nautilus-without-nautilus-ac#672553 You could make a bash script like shown in the post and use polkit to open the password prompt and run a command as root.

Most phones can, it’s just disabled in software, you can enable it in Androids developer settings.
