Although Home Assistant is primarily meant for smart appliances and IoT products, it has evolved into a powerful platform capable of pairing with everything from LLMs to server platforms. After all, you’ve got hundreds of integrations built into HASS, alongside plenty of apps (or add-ons, as we veterans call them) that can connect more services to the smart home platform. However, the real fun begins once you set up the Home Assistant Community Store and start perusing the sheer number of integrations, cards, and blueprints designed by tinkerers.

The TrueNAS integration is one such optional HACS offering that can hook the all-powerful ZFS-based NAS distro with Home Assistant. At first glance, it may not seem all that useful. But when you consider the custom dashboards and trigger-action automation provisions on Home Assistant, this integration becomes a must-have for home lab enthusiasts.

The HACS integration for TrueNAS scans all the essential NAS entities

It’s great for creating custom dashboards featuring different aspects of your storage server

If you’ve ever tinkered with the Proxmox community integration available on HACS, you’ll feel right at home with the one for TrueNAS. By reading the disks, storage pools, applications, network shares, and other important aspects of a TrueNAS server, it adds them to Home Assistant as entities – effectively turning them into any ol’ smart device in your arsenal.

On the dashboard front, you can use it to design a custom UI featuring the NAS stats you’d like to monitor in real-time, with certain tools like Bubble Card providing even more customization options for the interface. Or, if you’re anything like me, you can pair it with Proxmox and Docker integrations to create an all-in-one dashboard featuring entity cards of each platform. The TrueNAS integration can even pull snapshots tasks and virtual machine stats, and you can even control the VMs and backup operations directly from the UI. So, you can get a lot more functionality out of your Home Assistant-powered NAS interface instead of just using it as a monitoring utility. And since we’re already on the subject of controlling TrueNAS…

Its real utility lies in creating automations that involve smart devices and your NAS

Even the virtual guests running on your storage rig are fair game

Considering that you can control entire smart home setups using trigger-action rules, it shouldn’t come as a surprise that you can use the entities imported from TrueNAS to design automation chains. No, I’m not just talking about the notification workflows where you’ll get pinged on the Home Assistant companion app any time a pool goes offline, TrueNAS has an update, or a virtual guest crashes. For example, you could design a chain where every time a new data pool’s capacity exceeds a specific threshold, it gets archived as a snapshot. Or, you can design one that causes companion apps to stop when a parent virtual guest (say Jellyfin) shuts down. And that’s just the automations involving your TrueNAS system.

I’ve paired numerous smart gizmos and home lab appliances with my HASS instance, and the TrueNAS integration opens doors to some wacky automations spanning multiple systems in my arsenal. For example, before I had my 3-2-1 backup pipeline, I’d force Proxmox to send virtual guest data to a PBS instance, and upon receiving these snapshots, HASS would trigger a Cloudsync task that saved them to the cloud. Speaking of off-site backups, the HACS integration for TrueNAS supports multiple device configurations, and with a little bit of Tailscale wizardry, it’s possible to pair numerous devices running this distro with Home Assistant.

The beta version of the integration is compatible with TrueNAS 26

It’s fairly easy to set up, too

If you’re an avid TrueNAS user, you’re probably aware that the distro strips away the REST API in the beta version and instead switches to a JSON-RPC 2.0 over WebSocket API for tasks that involve external tools. Unfortunately, any integrations relying on REST endpoints won’t work anymore, and it’s something I learned the hard way. In fact, the Home Assistant community integration for TrueNAS stopped detecting my storage server when I installed the latest beta release.

But one quick trip to the bugs section of the integration’s GitHub repo revealed that Home Assistant fails to access TrueNAS if you use its stable version – the one you’d install by default on HACS. In particular, switching to version 1.4b4 of the community-created TrueNAS offering caused Home Assistant to detect my pre-configured TrueNAS instance immediately.

Just to test whether the beta integration works with fresh connections, I spun up a virtualized TrueNAS instance and updated it to version 26. Sure enough, once I’d entered the TrueNAS URL and added a new API key, I was able to connect the virtualized NAS server to Home Assistant.
