Looks like there’s two ROMs available - Lineage 15.1 and Mattmon’s 8.1 ROM. It looks like Lineage doesn’t enable using tapping of the display to wake up the screen. Wondering if that feature is available on other ROMs, like Mattmon’s 8.1 ROM?
Yes I did, but even still not seeing anything related with reboot/shutdown or similar in my LineageOS 
i’m at work but will have a look, hopefully tonight or over the weekend
Maybe it’s not the right place, but I’m trying… My Lenovo have worked for 1 month and today the screen don’t have backlight. It’s all black… the brightness is at 100% but no screen. Try factory reset and nothing change
Correct. Unfortunately this Lineage build doesn’t support tap screen to wake. I think Mattmon’s build does IIRC, but there are other issue with that build - eg audio. It’s a toss up as to which features you need. Never is perfect but in my testing of both, Lineage came out on top.

Hi,
Nice work! I have two questions: are your washer / dryer „smart”? I have quite old washer and I am wondering if there is any way to get it into HA (except of using a smart plug to monitor energy use on it…)
Are you using the Lenovo camera to wake up fully kios from sleep mode? Is there a way to get this entity active in HA?
Thanks a lot in advance…
Best, J
Hi, yes I have Samsung smart washer and dryer. They’re excellent machines. They connect to SmartThings and I then get the data from that. It is cloud based however but it has been working reliably so far. Probably one of the most useful sets of data to show on a dashboard 
To wake the screens, I have a set of automations linked via mmWave presence sensors in each location. That works flawlessly.
Thanks a lot!
The Playstore version of WallPanel seems to constantly crash. Anyone find a stable version that works with LineageOS on the Lenovo?
Not being able to wake the screen is more of an issue than I originally thought. The volume buttons don’t wake the screen. And there’s no power button to tap. The only way is to slide the camera privacy shuttle slider back and forth, that’s really hard to do. I’m not sure that slider is designed to take that much abuse.
I guess a motion sensor to make a wake API call is the only solution if you don’t want the display on all day long.
The volume button do wake the screen - if you have that set in the settings. Looks like you don’t have it set.

bugga, sorry, totally forgot, the long weekend got away from me, I’ll take a look tonight, I’ll put a calendar reminder on for me 
Hi @bjm
I can not see this option on my device under settings. Maybe because your version is different than another I installed: Is this the perfect standalone tablet for HA? ?
However from your options looks like there is no way to shutdown the device either, mainly wake or sleep one. I wanted to find a way to shutdown it properly without need of power off the electricity… but looks like it is getting hard 
Thank you for your support anyway!
My thread (this one) is about Lineage and not Mattmon’s 8.1. They are quite different although both based on Android 8.1.
Thanks for reply @pgale I don’t know why but convinced Mattmon’s were based on LineageOS 15.1…
I may need to consider installing yours since have shutdown capability which I want and seems you got it really stable.
Thanks for sharing!
Not sure Lineage does shut down. I don’t ever do that so haven’t tested that. I think someone else said there were problems. None of these ROMs are 100% perfect, Lineage is the best for my use though. I think Lineage needs root access to shut down and restart and that was tricky when I tested it - but didn’t persevere.

I managed to root Lineage 15.1 for the TSV. I somewhat followed along with this video https://youtu.be/8o5YILpoIvs
To summarise:
First download the Magisk apk to your computer: Releases · topjohnwu/Magisk · GitHub
Then connect a USB to the TSV and in ADB and Fastboot++ enter
adb reboot recovery
Once booted into recovery mode select Apply Update - ADB Update. Then in ADB on your computer enter
adb sideload Magisk-v28.apk
I used v28 but it probably works with other versions. Once it’s finished restart the device. Then open up to Magisk and hit Install. It’ll complain about something to do with ‘Your device needs to reflash Magisk to work properly’. Then select ‘install direct installation’. It’ll then do its thing and root your device.
From there when you open an app that can do root actions it’ll prompt if you want to let it work in root mode. In Magisk you can select the Superuser tab to see what apps you have granted permission to. I had to restart Fully Kiosk Browser then manually grant access in the Superuser tab.
Maybe you don’t even need to boot into recovery mode and can skip straight to installing the apk directly in LineageOS and seeing if it can root it that way.

Thanks for the write up, that’s very useful
I just found out how the navigation bar changes with the display rotation:
When adjusting the display scaling (Android Settings > Display > Advanced) to the minimum or one step above the minimum, the navigation bar rotates with the screen. Everything higher than that leads to the known behavior, ie. the menu sticks on the short side of the screen
Sorry, didn’t check for the English option name, but I think it’s clear what I mean.
