2 things I found on a quick search:

1st Look if your GPU is actually designed to have a „headless“ start - if not you most likely need that dummy adapter that others mentioned

2nd In the bios settings look for something like an "Halt on all errors" option and disable it. If the GPU is the problem than you might get to start it anyways without any monitor connected

I second Valetudo. I’m using it on a roborock S5 and installation was pretty straight forward. Even if it takes more effort to „root“ your vacuum it is definitely worth it. I also integrate my vacuum in HA over mqtt.

SelfToasted

But I would assume you're used to using a 'manual' keyboard whereas if you only grew up on touchscreens its probably more difficult to get familiar to.

The prevelance of touchscreens much rather results in people lacking skills/efficiency/speed when using a regular computer keyboard

Yes it is that simple. In the beginning you can reach your services via localhost or simply the IP address of your laptop (followed by the specific port).

Start with Docker/Containers.

Once you understand the basics of it you can start selfhosting all sorts of applications from/on your laptop with very little effort. For Docker Command Line Basics there are tons of free tutorials online. If that’s to big of a step in the beginning, start with a Portainer (spinning it up is basically just copy and paste one little command) the rest can be done from the GUI. Docker will also help you to figure out what you might think is worth „selfhosting“ for yourself. Because selfhosting is almost like clothing: Everyone has their own taste and style.

Make sure you introduce your USB dongle through ProxMox to the VM on which HA ist installed. There is an USB-option in the menu for your VM where you can choose which USB device or port from the Host should be passed trough. Once that is done figure out how the USB is connected to your HA VM via the HA shell. Something like

ls /dev/tty*

should give you the path you will need to integrate it into HA (if autodiscovery doesn’t work).

That escalated quickly.

But I guess drugs and friendships never really go hand in hand.

Was looking for that comment 😅

Google

They made private data the „new gold“ which it is today long before social media started exploiting it. Changing their motto /code of conduct „Don’t be evil“ into „Do the right thing“ (for our shareholders) didn’t benefit their reputation either…

• Added the eventually for Murphy’s law because in its original version it kinda implies that everything that can will go wrong right away
