What this workflow does
This AI workflow has 17 nodes and runs on a schedule (every 24 hours). Along the way it connects Slack, Postgres and OpenRouter Chat Model.
How it runs
Trigger: On a schedule (every 24 hours).
- Simulate Vehicle Data (Edit Fields (Set)): sets 13 fields: vehicle_id, make, model…
- Fleet Data Source (Code): runs custom JavaScript code
- Analyze Maintenance Needs (Edit Fields (Set)): sets 7 fields: needs_oil_change, low_brake_pads, low_tire_pressure…
- Split Fleet Data (Loop Over Items (Split in Batches)): loops over the items in batches
- Check If Maintenance Needed (If): checks a condition and branches into true / false
- Generate Alert Details (Code): runs custom JavaScript code
- No Maintenance Needed (Edit Fields (Set)): sets 4 fields: vehicle_id, driver, summary…
- Send Slack Alert (Slack): uses Slack
- Log to Database (Postgres): uses Postgres
- Aggregate: combines items into one
…plus 5 more steps. See the full node list below.
Services it uses
Before you upgrade to n8n 3.0
1 thing in this workflow is removed in n8n 3.0. Fix it before you upgrade:
- AI Agent v1 (old agent modes) in AI Maintenance Analyzer (v1.6): replace with Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent.
Rather not rewrite it? Many of these flows can be rebuilt in Make (free plan).
| Removed in 3.0 | Replace with |
|---|---|
| AI Agent v1 (old agent modes) AI Maintenance Analyzer (v1.6) | Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent. |
