I’ve built a native Synology DSM package for running hass.io. It is using Docker so that package needs to be installed and running first. It’s been tested on various x64 based versions running DSM 6.1 or more.
Everything is quite straightforward but make sure to create a Shared Folder to use for data storage and select that in the first dialog.
Installation is made trough Synology’s Package Center by adding a manual package (with the file below). Just make sure to install the Docker package first (I’ll try to make even that automatic in a future version).
