Your smart home, fully under your agent's control

AutomationDeveloperSecurityProductivityAnalytics

Home Assistant is the open-source home automation platform that runs locally on your own hardware — no cloud dependency, no data leaving the building. Connect it to Actionist and your agents gain direct access to every device in the building: they can read sensor states, call any service across lights, climate, locks, and media, fire events into the automation engine, and retrieve full entity histories. Whether you're automating an office, a showroom, or a distributed facility, the agent acts on real device data the moment it matters.

Smart office welcome for every new client visit

When a client-visit confirmation lands in Gmail, your agent reads the Home Assistant configuration to identify available meeting room scenes, fires the 'client-ready' service call to set lighting and temperature, then posts the room status and parking instructions to Slack — and drops the appointment details on Google Calendar so nothing falls through. The client walks into a room that's already at the right temperature, with the right light, before you've had to touch a single switch.

How to plug Home Assistant into Actionist

Pick the connection method that suits your environment.

The fastest path to full Home Assistant control. Connect via the Home Assistant MCP server and the agent can read states, call services, fire events, and retrieve logs through a single permissioned channel — no token management, no manual API wiring.

1
Open the Apps tab

Find Home Assistant in the Apps library and click Connect. MCP is selected by default.

2
Authorise in Home Assistant

The agent opens your Home Assistant instance's OAuth flow. Select the user account to connect and approve the requested scopes — state read, service call, and event access are pre-selected.

3
Test the connection

Actionist runs a read-only call to verify the handshake. You're ready.

FAQs

Questions about Home Assistant + Actionist

How do I connect Home Assistant to Actionist?
Open the Apps tab, find Home Assistant, and click Connect. The recommended path is MCP — the agent handles the OAuth handshake with your Home Assistant instance and confirms the connection with a read-only state check. Alternatively, use the API Token method: generate a Long-Lived Access Token in your HA profile settings (Security → Long-Lived Access Tokens) and paste it alongside your instance URL. The token method works well for self-hosted instances on a local network where OAuth redirects aren't available.
What permissions does the agent need in Home Assistant?
For read operations (Get all states, Get entity history, Get all services) the agent only needs read access to your Home Assistant instance. For write operations — calling services, creating events, firing webhooks, upsert state — the connected user account must have the ability to call services in the relevant domain. A dedicated Home Assistant user created for Actionist with appropriate role permissions is the safest approach; avoid using an admin account for automated access.
Can the agent combine Home Assistant with other apps in one workflow?
Yes, and that's where the most useful automations live. The agent can read a state from Home Assistant, use the result to make a decision, call a HA service, and then post a Slack notification or log a row to Google Sheets — all in one uninterrupted sequence. Common patterns include: Gmail triggers that activate HA scenes, Google Calendar events that set HVAC pre-conditions, and HA state changes that create ClickUp maintenance tasks.
What are the most useful automations for a business using Home Assistant?
The highest-leverage automations centre on facilities operations and cost reporting: daily anomaly sweeps (agent reads all states at 07:00 and flags open doors, offline sensors, or out-of-range temperatures), monthly energy cost reports (agent reads entity history, applies tariff rate via template, outputs to a spreadsheet), and event-triggered scene management (agent calls the right service the moment a meeting or visit fires in the calendar). Security log retrieval — pulling entity history on demand for compliance queries — is another high-value use case that previously required manual dashboard navigation.
Does Actionist work with self-hosted Home Assistant instances?
Yes. The API Token connection method is specifically designed for self-hosted instances. Provide your instance URL (e.g. http://homeassistant.local:8123 or your external domain if port-forwarded) and a Long-Lived Access Token. For instances only accessible on a local network, run Actionist on the same network or expose HA via a secure reverse proxy. The MCP path also works with self-hosted instances as long as the instance is reachable from the Actionist runtime.
How do I avoid trigger loops when the agent writes states that could re-fire a trigger?
Two safeguards work well in practice. First, include a state-check step before writing: the agent reads the current entity state and only calls the service if the state isn't already what you want — breaking the retrigger cycle before it starts. Second, scope your triggers narrowly by entity ID and new-state value rather than listening to all state changes; a trigger on sensor.office_temp crossing 28°C only fires when the threshold is crossed, not on every update. For automations that write virtual sensor states, use a cooldown attribute or a dedicated input_boolean as a lock to prevent re-entry.
What rate limits should I be aware of when the agent calls Home Assistant services frequently?
Home Assistant's REST API is self-hosted, so rate limits depend on your hardware rather than a vendor-imposed cap. On a Raspberry Pi 4, expect comfortable handling of up to 10–20 service calls per second; on a more powerful host, the limit is effectively your network throughput. The main constraint to watch is the recorder database write rate — high-frequency state upserts can saturate SQLite on low-spec hardware. For polling patterns that run more than once per minute, prefer the WebSocket API via MCP over repeated REST calls; it holds a persistent connection and imposes far less overhead.
Can the agent react to Home Assistant events in real time, or does it poll?
Via the MCP connection the agent uses a persistent WebSocket channel to Home Assistant, so it reacts to state changes and events in real time — typically within 100–500 ms of the event firing. The trigger types (Entity state changed, Motion detected, Door or window opened, Low battery alert) are all event-driven; the agent doesn't poll. If you're using the API Token method without a persistent connection, you can still use scheduled runs to approximate real-time behaviour, but true event-driven reaction requires the MCP path.
