Anthias is a digital signage platform for Raspberry Pi. Formerly known as Screenly OSE, it was rebranded to clear up the confusion between Screenly (the paid version) and Anthias. More details can be found in this blog post.

Anthias works on all Raspberry Pi versions, including Raspberry Pi Zero, Raspberry Pi 3 Model B, and Raspberry Pi 4 Model B.

The quickest way to get started is to use Raspberry Pi Imager, where you can find Anthias under Other specific-purpose OS. Alternatively, you can find our pre-built disk images (powered by Balena Hub) here.

Do however note that we are still in the process of knocking out some bugs. You can track the known issues here. You can also check the discussions in the Anthias forums.

If you'd like more control over your digital signage instance, try installing it on Raspberry Pi OS Lite.

The tl;dr for on Raspberry Pi OS Bullseye Lite is:

$ bash <(curl -sL https://install-anthias.srly.io)

If you've selected N when prompted for an upgrade – i.e., "Would you like to perform a full system upgrade as well? (y/N)" – you'll get the following message when the installer is almost done executing:

"Please reboot and run /home/$USER/screenly/bin/upgrade_containers.sh to complete the installation. Would you like to reboot now? (y/N)"

You have the option to reboot now or later. On the next boot, make sure to run upgrade_containers.sh, as mentioned above.

Otherwise, if you've selected y for the system upgrade, then you don't need to do a reboot for the containers to be started. However, it's still recommended to do a reboot.

This installation will take 15 minutes to several hours, depending on variables such as:

• The Raspberry Pi hardware version
• The SD card
• The internet connection

During ideal conditions (Raspberry Pi 3 Model B+, class 10 SD card and fast internet connection), the installation normally takes 15-30 minutes. On a Raspberry Pi Zero or Raspberry Pi Model B with a class 4 SD card, the installation will take hours.
