What automation capabilities does Node‑RED provide for Home Assistant?

It offers visual flow creation with trigger‑state, API‑call‑service, function nodes, context storage, timer patterns, and error handling, all connected via the node‑red‑contrib‑home‑assistant‑websocket package.

Can I use existing flows from older Node‑RED versions?

No – node names have changed in recent releases. Using old names will break flows silently, so always use current node names as listed in the latest documentation.

What versions of Node‑RED and Home Assistant are required for this tool?

Node‑RED 4.x with Node.js 18+ and Home Assistant 2024.3.0 or newer are required to run the flows and use the node‑red‑contrib‑home‑assistant‑websocket nodes.
