FreeNAS is a popular free and open-source network-attached storage (NAS) operating system. While FreeNAS does have an interface of its own, it is nice to be able to see how much free space you have from the Home Assistant dashboard. Using the two guides below you can set up your Home Assistant to read FreeNAS statistics and messages and to control the system itself.
Unfortunately, I don’t run FreeNAS on my NAS any more, so there won’t be any more guides added in the foreseeable future. A commenter has kindly informed me that the code in my articles still works.
