I just use the openbox window manager. It has built-in support for putting the screen to sleep when not in use. In ~/.config/openbox/autostart, I put my script to launch chromium in kiosk mode. And then ~/.xinitrc launches openbox-session. And logging in triggers startx in my ~/.bashprofile. Systemd uses agetty to automatically log in the kioskuser on tty1 on boot.

5:45 Don't throw own service files to /lib/systemd/system/, there they belong to /etc/systemd/system/. But that is only for services that don't belong to some specific user. On a raspberry pi you have the default user that is automatically logged in. This user has its own systemd running, it is controlled with "systemctl --user ..." and has its service files in ~/.config/systemd/user/ That said, depending on your desktop environment (I assume raspberry pi defaults), there is another place to automatically start the script: ~/.config/autostart/ where you can put *.desktop files.

On which pis/ pi oses does this work? Only Pi 5?

[@techdude1541]

Our college capstone project was actually building out a custom car infotainment system (although we didn't have carplay) But for the hardware, we used a raspberry pi with touchscreen and a hifiberry dac to get composite audio then a car stereo amp to actually push it out to the speakers. Honestly unless you want a lot of software control in a pi I would consider a standard double din stereo. You don't have to worry about temperature issues and after costs are considered (crutchfield has stereos for ~$250-300) it's roughly the same

[@thetinkerer5300]

I built a head unit out of pi 4 a few years back. I used a time delayed relay to control the power to the pi. When the pi is turned off it still consumes a small amount of power, like a a few hindered miliamps. That was enough to kill the car battery in 2-3 days. For sound, I used an external amp, the amp was fed audio through a usb sound card, some pulseaudio changes needed to be made to stop it from popping all the time. Amplifing from usb will feed ALL electrical noise from your car into speakers, it's truly awful, so you'll need a usb power conditioner between the port and the sound card. I think it was 5 - 10 bucks on amazon, and the best solution I had tried.

[@theonlynafester]

same, I used the aux to a 25w amp and a ground loop isolator. Quality wasn't great.. but not bad. I didn't run it off the constant power line tbh but yeah, there's only one earth in a car which makes things tricky. I used the constant power line to run a a 12->5v bucky so I could have phone charging

[@xshadow-0]

A few hundred milliamps while turned off? And it killed your battery in 2-3 days? An idle Pi while turned ON draws 540 mA. That still should kill a battery in over a week, most likely two weeks. Not to mention it's IMPOSSIBLE that it draws HUNDREDS of milliamps while OFF. It should've been fine for a few months. You must've done something wrong or had a bad battery. Besides, if you were concerned about power, why not power Pi from the lighter socket? It gets turned off along with ignition (at least in all cars I've ever seen).

[@theonlynafester]

@xshadow-0 yup yup. This is why I was incredibly fortunate - I lived next door to a guy who did car audio and he made sure I didn't destroy my car and pi just for Waze and Spotify.

[@AndersJackson]

@@xshadow-0 sounds like something else is drawing power through the RPi, if one get that much drawn when turned off. Maybe through USB or something like that. But yes, a relay will definitely turn the Pi and auxiliaries off when the car is not running. But there are other sources which will turn of when the key isn't on, that is better suited. It can be turned of by the Pi, with a self holding circuit, and then when turn of, the Pi can release the self holding relay. So it get started after the key has turned on, and turns of when ready when the key has turned off. One should probably think about the lower voltage when the car is starting.

[@pcurd]

I used the original screen to make a bedside smart screen, I wrote scripts to start KZbin in chrome, to stream my favourite radio station then turn the volume down and turn off the screen, and a few other night time things. Each script also had a shutdown command on a timer so after 2 hours it would shut the pi down. This didn’t turn it off-off (Pi 3, and later 4 problems) but I had a foot switch on an extension cable that I would hit every morning to turn it off properly. That same switch turned it back on when I wanted to use it. Paired with some USB speakers it worked fine but was bulky and eventually the footswitch technique got tedious so I replaced it with a cheap android tablet - although now I have to control the volume and turn off the screen manually. I also have to charge it every 5-7 days which is also annoying. One day I’ll build a perfect setup!

[@domramsey]

This is very cool. I want to say though that if you're specifically interested in Home Assistant, then an old Android tablet and the "Fully Kiosk" app is a much more useful - and useable option. You can have it run from boot, and it gives Home Assistant access to a load of the sensors on the tablet, meaning the front camera can be used to detect motion and automatically turn the screen on when someone stands in front of it. It's very powerful and given it's really just a wrapper for a web browser, it runs well even on old & low power tablets.

[@U1TR4F0RCE]

@@U1TR4F0RCE I have a couple of de-amazoned fire hd10 tablets, a Fire HD8, a Samsung Galaxy Tab A, an old Acer tablet and a couple of android phones running as HA touchscreens Running the HA android app. They all do a fine job. Since most android devices expose things like battery level the charger can be connected via a smart socket set to turn on at 10% battery and off at 90%. This reduces the problem of bloating batteries due to constant charging that some badly designed devices seem to suffer from. The HA server itself runs on an old Wyse thin client I had laying around.

[@faeranne]

The early rotation option is tricky but possible, as I'm pretty sure the driver used on this board uses the same kernel entrypoint that the old screen used, Kernel Mode Setting. It's just a kernel command line change (`video=DSI-1:800x480@60,rotate=90` for the original display, adjust resolution for display 2), which can be put into cmdline.txt on the boot partition. I believe even the config.txt can be set to rotate the pre-kernel boot screen (`display_lcd_rotate=1`), but only when used on a SD Card, and only for pre-kernel environment. NVME, USB, and Net boot all start after the bootloader starts rendering, only the SD Card is read before the GPU finishes starting up.

[@dudeh9702]

Home Assistant dashboard is a perfect use case (especially with dimming). I have a future project to build out a Hi-Fi music control interface (maybe piCorePlayer project) that pulls in my entire local (legal!) music collection from the NAS and outputs the audio through some fancy DACs and speakers, so I'm very happy there's a newer Pi display out.

[@chompdoesathing]

To be fair the UI of Android Auto and Car Play and OpenAuto/Dash are large and chunky and kind of built around super simple touch controls so even the old screen worked well and from my limited testing in an old build (15) of open auto the new one worked fine there too. Only thing of note I could figure out was there was no multitouch support in Android auto back then, but then again the 9" screen in my 5th gen RAM doesn't do that either so I think that's more of a platform limit than a screen issue (or it could be entirely supported now and I just don't have a new enough vehicle to test that against lol)

It might be advisible to use a DC/DC converter in the car that has proper 12/24V UVLO limits which prevents accidental deep discharge. Also it needs to fully control power to the Pi (with it's power mgmt signals factored in) to avoid trickle current drain when it's powered down and goes to a simple halt() state (just like /w old AT PSUs) or get power from IGN as an alternative and loose the ability to to run it from the battery as a compromise and risk SD corruption (tmpfs/ssd/run with fs mounted ro?). An input circuit that has noise filtering and at least transient suppression ensures a long life for the Pi.

Ask me this 2 months ago and I would agree that it had setup issues, but it appears to be more supported today! It is a great alternative to consider given the size and price. I was trying to use this display for a drone ground control station until I realized no GCS software works well on a Pi, so it has been sitting around since summer... Now I am making a Home Assistant dash like yours! I have done similar setup to your kiosk mode for a work project.

Years ago I got the original Pi Touch Screen, a Raspberry Pi 3, a audio hat (forget the specific model) that I could wire the speakers up to, and one of the USB power switches from Mausberry Circuits to build a car computer. I did a similar thing as you, where it would launch Chrome into kiosk mode, and then I built a node.js custom touch interface that would switch between bluetooth audio, MPD, and rtl_fm. But it was always a little bit flakey (mostly the bluetooth) and didn't have CarPlay support (I don't think that dongle you mentioned was available then). So in the end, I ended up just buying one of those cheap Android dual-DIN car stereos on Amazon a couple years ago. It's not the greatest thing ever but it's a lot more reliable (and it spends most of it's time in CarPlay mode anyway). I do miss tinkering on the Pi car computer, though.

The screen was somewhere in the US$40-70 range depending on whether you get the 480 or the 720 pixel tall version (both are 1280 wide), hooks up to the Pi via MiniHDMI, and can hook up to regular-sized HDMI as an output as well (I haven't used it that way yet, so don't know off the top of my head if it needs to be externally powered for that or not).

In my experience, when it gets super cold, like -40c. Electronics still work. Batteries are very compromised although lead acid batteries only loose 60% or so. Screens are also very affected but this mostly revolves around a single screen refresh taking 5-10 seconds. While driving, the cabin temperature increases and the devices own heat warms it up it gets faster and faster. The touch screen has several problems but it depends on the type. Again, it warms up in 1 - 10 minutes. I don't know the tech type in the screens I've used but this has been common among all the screens I've used outside. Personally I wouldn't be scared to try your specific screen, I don't think it would break, Just function like an old e-ink display trying to play a movie until it warms up to -20 or so. That being said, I've not tried your specific screen.

The best Smarthome is the one which doesn't need buttons, doesn't need voice control. Over the past two years I got so much stuff automated that I really don't need to control that much anymore. Same in a Tesla. Automation to a large degree is just so good, you just miss the buttons almost never. In your case I would get one of those car-play screens for your own car. There are many outthere which cost little and have the bluetooth/wifi connection right built in. And do the temperatures and 12v etc. just without the hassle of setting up a pi and probably more efficient. Cause pis use quite a lot of power, btw everything above 2W in standby is a lot imho.

[@WattTheTech]

I'm waiting for that 15" Pi display. It's fine that's not touch. Seeing that a few months ago I need it. It looks nice. Please Pi release it before Christmas

[@abhimaanmayadam5713]

you could get a cheap driver board for any old laptop panel off of ebay. Its basically that

Jeff please. I need a full video guide to install (kiosk/ha). I fail on the second of code.

[@elpanteroazul3474]

Great video. I am now inspired to start learning Raspberry Pi. Following the Apple CarPlay.

[@Luix]

How does it work with QT apps?, maybe custom apps.

[@JeffGeerling]

I didn't have one handy to test, but it should be good for that, as most of those HMI devices I showed are meant for custom QT apps.

[@MakeOrBreakSociety]

I'm using my OG display for a home assistant dashboard and it hasn't been great. However your setup looks interesting. Looks like I'll be setting that up as a weekend project😅

[@JeffGeerling]

Certainly worth seeing if it's any better with the higher resolution!

[@MakeOrBreakSociety]

@@JeffGeerling the way mine is running is with pios lite I have no touch keyboard it's getting old having to plug one in ever few days. I'm really excited to have a working touch keyboard 😂

For Android Auto you can flash CrankShaft on the sd-card. With this you don't need a dongle.

2:00 For one second there I thought I was looking at the code-animation from The Matrix lol.

[@wouldntyaliktono]

This is great! I think for my needs I'd really love to use an e-ink display to act as a "good things to know" dashboard for next to the front door. Do you have any suggestions (or follow up videos) about that kind of thing? I've considered using ESPHome for that purpose, but it feels clunkier and I like the flexibility of a linux native development environment.

[@JeffGeerling]

I've looked into eInk here and there, may do a project with it at some point. It's great for status display!

[@jeffreypohlmeyer8782]

For what it's worth, I can rotate the terminal on my Lenovo IdeaPad with this command: echo 1 > /sys/class/graphics/fbcon/rotate (Value can be one of: 0=Normal; 1=Clockwise; 2=upside-down; 3=CCW) It might be possible to add something like that into early userspace to force the boot messages into landscape but I doubt if it would be worth the trouble.

[@JeffGeerling]

We figured it out over on GitHub! (Thanks especially to one of the YT comments, too!).

Here in Phoenix the inside of your car will get over 140 160. The outside temperatures are 120 plus. This last summer we beat the number of days of over 110° and that was even all the way in October we were still hitting 110. And it was also the first time ever we'd ever hit over 100° in October. But yeah, that touch screen would not survive a single summer day in Phoenix. It might survive a winter day but the winter is up to about mid '70s during the day, so inside the car should be maybe in the '90s or even close to 100

[@8bitHuman]

8:20 its not fun. we should get rid of Fahrenheit at all. Also inches and foot. Celsius is the most logical thing. 0C° water freezes. 100C° water boils. as simple as that.

[@andrewberg9611]

I am human not water. How temperature feels to me is more relevant

[@am2dan]

My other hobby is woodworking, so my 7" Pi weather display has a nice walnut case. For the UI I write directly to the video memory buffer and catch touch events at a low level. But the cursor is always blinking in the corner despite my efforts to get rid of it. I'm gonna have to try that unclutter package. Thanks!

[@CedroCron]

You could take the Pi/Pi-display out of the car with you when you aren't in it, similar to 1990's when people would take their stereo faces off to prevent theft. 😂😂😂

[@JeffGeerling]

Ha! I had one of those head units. I'd pop off the little front display and toss it in my glove box. Thought I was pretty cool with a CD player in my Olds lol

[@CedroCron]

@@JeffGeerling And probably worth more than the car right? ... First car for me was a babe magnet... 1986 Dodge Caravan, beige with gold trim and tan interior. 4 Cylinder 90hp of raw power. Used to blow blue smoke on start-up and a bit taking off from a light... But the JVC removable face CD & MP3 radio was awesome! Hahahaha ... Those were the days!

[@JeffGeerling]

@@CedroCron About the same price, heh.

[@theodoros_1234]

Since Raspberry Pi OS now runs on Wayland, forcing your web browser to use Wayland should improve touchscreen support (and laptop trackpad gesture support). Chromium has (imperfect but functional) Wayland support, but it defaults to X11. Alternatively, you could try using Firefox, which has it on by default.

[@tcghunter9196]

I do not mean this as a bad thing by any means, love the vids, love what you do, started my home lab journey from your pihole and speed test monitor. Just a funny thought when you kicked on the screen and booted into home assistant. You made a stream deck >< if you had home assistant have 32 buttons in a grid, you just recreated the wheel on this one. Obviously there's much more you can do than the simple things a deck can do, but you could use this for both

[@GeFlixes]

I've been using an okd Android tablet as a secondary touch screen. a 90 or 180 degree USB adapter and a kickstand is all it takes, and it saves a old device with a dead battery from the ewaste bin.

[@the_beefy1986]

No too shocked that RPi is heading to larger LCDs. I've been seeing similar sized units on AliExpress the last few months for like $15! I picked one up last time I was buying a few things there and it's coming in next week (in theory). It even has 75mm VESA mount holes, and of course a reasonable stand cost more than the display hahaha

[@Starlite123]

Amazon has some cheap car stereos that would go perfect in an old car. They are about 35 bucks. And you can even get them with touch screen monitor for a few bucks more.

[@_DSch]

If you want to use carplay/aa with close to zero delay on linux I have a fork of node-carplay which has some fixes :D Audio has some alsa mixers too since I wanted different volume levels for media and navigation and proper (as per apple spec) audio hedging. I had it running on a PI2 for some years now, have to update the repo though since gstreamer is blazing fast compared to mpv. A reimplementation in rust would be better, it could even be made native since the only thing needed for carplay is an mfi chip (which i have) on i2c and a usb host&device capable usb port. Since openauto got apparently sold and is unavailable rn I think a community project would be awesome. My Idea was to use gstreamer for playback and UI and code in the background that handles background stuff like ui logic, canbus messages and buttons in the car - needs more people than a single person though.

Is the argon thrml fan and heatsink near silent? I find the official active cooler a bit noisy

[@JeffGeerling]

The sound is quite similar. Slightly different pitch but the sound level is about the same.

[@jonasslettingjensen5032]

I used the original touch display to control a drinks machine. Paired with a Raspberry Pi and some motors it could mix together drinks with quite a few ingredients.

[@johnknight7293]

My (version 1) touchscreen sits on the wall in the hallway showing weather info, my Google calendar and a "screensaver" weather satellite image. After 7pm it switches to random A.P.O.D. images. Works with UK or Spanish weather APIs (no good for you!) and is all coded in Java. UI is JavaFX.

Would it be possible to use 5 finger touch to exit the service or application? Perhaps show desktop on 5 finger touch?

[@JeffGeerling]

Possibly! So far I haven't seen anything in Pi OS take advantage of more than one finger at a time.

[@Sqaaakoi]

KDE has a lot of 3 finger touch screen gestures that could do this, and you can also configure actions when swiping in from each edge of the screen

[@harriet-x.x]

i have a dedicated battery and alternator to run a small rock64pro and a 10" display for carplay in my old 1991 CRX been working smooth for years now! Better than some of the new cars with all display only 😕

[@djlalorocks]

I am with you about modern vehicles taking away audio interface options. I would be interested in your pursuits in this field. I tried using a rp5 headless, with my phone as an interface with Moode. I live in south Texas and could not keep the rp5 in the vehicle and expect it to function - way to hot.

[@Ziggurat1]

What you show when you say the boot screen is rotated is called console, and it can be rotated. The name sound obvious for someone like you, but I'm just saying that's the technical name. A kernel boot parameter can be used to rotate it! fbcon=rotate:1 (or 3) should fix the issue! It is possible, if the kernel can recognize the model of the screen, if the screen communicates edid, the raspberry pi foundation can add a quirk (that's the technical term the kernel guys use for a patch like this) so the kernel will have the landscape rotation by default on this screen. But maybe the rpi foundation thinks landscape is optional. You can optionally use Plymouth to display a rotation agnostic animation instead of the kernel boot information

So my parents got a 2021 Honda CRV with a semi-basic entertainment center and I think it's the best mix of simplicity, accessibility (still using knobs for the heat/AC so you don't HAVE TO look away from the road - AND having steering wheel controls to change volume/track and cruise control... plus the buttons are in a good layout) I connect my phone with bluetooth and it does calls over the speakers if I want, plus I can control my phone from the steering wheel.... BUT it doesn't have GPS.... but you can connect to you phone with bluetooth and will come over the speakers and you can control the volume with the steering wheel... but the map doesn't come up on the car's screen.... but mounting a phone is easy - the car has lane keep assistant (it rumbles the steering wheel when you get too close to the lines) and auto braking which I didn't know about until it started doing it way sooner than I would have and it SCARED ME!!!! - And it's great on gas..... Oh and it has a rear-reverse cam too, which I've grown to love LOL - - So you don't HAVE TO get the latest and greatest tech when you buy a new car, and I think they would have electric cars that have the same level of tech that I listed here (I think that's the type of tech that you'd want in a car too... I think MOST PEOPLE would be just fine with that level of tech (except maybe built-in GPS) - you don't need all the apps, and all the internet connection so you get album art for the music you already own.... - so MAYBE a Honda is a brand you haven't looked into, and the small SUV's carry 5 adults snuggly lol, but 4 comfortably... and they have a decent size trunk too... So maybe you ought to look into the CRV and see if it's something you'd like (idk if you want and electric car or not, but I'm sure they have a good selection) - I hope this helps is some way :)

I considered using an old iPad like that, the one downside is managing a LiIon battery, I hate having so many devices around with those batteries and either managing charge, or risking keeping the battery 100% over long periods, which can lead to expansion more quickly.

[@JonVB-t8l]

I know you are hesitant to get a new car, but my Tesla has been bullet proof and it's super easy to add features and games. You just add them via the browser. Jellyfin works great, emulatorJS even works while driving (although you this is something I'd recommend for passengers only), Home assistant is hosted locally but controlled via the browser can be super useful and integrated into voice controls in the car! Thats not even mentioning BT support is very wide spread and the modding community and open-source nature of Tesla CAN bus and Ether-loop make things like track and drift mode possible with plug and play adapters from sexy-button to diy raspberry pi solutions! Host things on your phone, export things from your car to track it's use locally is also super cool and shockingly easy. My favorite thing is, because the camera feed is exported by the car via the Tesla app. Every hour or on-demand I can have it take a snapshot to add to my existing home security system and even export events from sentry mode to my home security system!
