Hello!
Can someone tell me if it is easily possible to install hass.io via USB Stick onto an Raspberry Pi 4B?
I tried it flashing the image from https://www.home-assistant.io/hassio/installation/ onto an USB Stick, but the Pi did not boot.
When I tried it with an SD-Card it was running without a problem.
Is there any trick to get this work?
afaik there is no firmware yet for the Pi4 to boot from usb (any OS, not just hassio). Only for the Pi3. It should be possible to just put the bootloader on sdcard and everything else on usb, but I cant help you there.
You should be able to mount the USB drive persistent.
Knowledge of Linux is required to perform these steps successfully.
How ? Have a look here:
Step 1:
This step is important if you have/will have >1 USB device connected to the Raspberry

Step 2:

After that you can mount the storage in one or more filesystems.
Hmm?
Which answer should I use? The first one says it is not possible to boot from USB, the second is telling me that I can mount USB drives permanent.
They dont contradict each other. The bootloader needs to be on an sdcard for now, as the Pi4 cant boot directly from usb yet, but you should be able to put at least the docker images and possibly more than that, on usb. And for that to work, I guess you need USB drive persistence, but thats above my paygrade.
