FAQ

Questions about Home Assistant + Slack.

How long does it take to connect Home Assistant and Slack on Tiny Command?

Under two minutes. Authorize Home Assistant and Slack once each, drop the Home Assistant trigger and Slack action onto a workflow canvas, map a couple of fields, and publish. No code, no glue.

Is the Home Assistant ↔ Slack integration real-time?

Yes. Both Home Assistant and Slack expose webhooks, so events from one fire workflows in the other within seconds rather than on a polling interval.

Can I filter or transform data between Home Assistant and Slack?

Yes. Add a Filter node to only pass through matching events, a Switch node to branch by value, or an AI / Code node to transform payloads before they hit Slack.

What Home Assistant events can trigger a Slack workflow?

Use Tiny Command's universal Webhook trigger to receive Home Assistant events, then run any of the 45 Slack actions downstream.

Do I need a paid plan to use Home Assistant with Slack?

No. There's a free tier that covers most Home Assistant+Slack use cases without a credit card. Paid plans unlock higher run volumes and team features when you outgrow it.

What if I want Slack → Home Assistant instead?

Build it the same way, in reverse. There's a dedicated /integrations/slack/with/home-assistant page with the reverse-direction triggers and actions.
