Nous Research added an official Hermes Agent plugin for Home Assistant. It provides a gateway that forwards state change events and a toolset of four commands to list entities, get state, list services and call services. The plugin works with Hermes Agent version 0.21.5 or newer and only needs a long‑lived Home Assistant token. Installation is a single command from the Hermes plugin catalog.
