+# Monitor grid telemetry and automate compliance alerts with GPT-4o and Slack
+
+# 1. Workflow Overview
+
+This workflow ingests electrical grid telemetry through an HTTP webhook, uses a central AI coordination agent plus four specialized AI sub-agents to validate signals, assess regulatory compliance, generate reports, and determine operator notifications, then stores results and distributes alerts/reports through Slack and email.
+
+Target use cases include:
+
+- Real-time anomaly detection for energy grid operations
+- Automated compliance monitoring against grid standards
+- Operator-facing alerting for critical or warning conditions
+- Continuous storage of validated telemetry and compliance events for audit trails
+
+The workflow is logically organized into the following blocks.
+
+## 1.1 Telemetry Intake and Central Orchestration
+
+A webhook receives telemetry payloads and passes them to a central Coordination Agent. This agent uses a chat model, memory, and four tool-agents to orchestrate validation, compliance assessment, reporting, and notifications.
+
+## 1.2 Signal Validation and Structured Parsing
+
+A dedicated Grid Signal Agent validates generation, load, and storage telemetry. It uses a model, a code-based validation tool, and a structured output parser to normalize results into a predictable schema.
+
+## 1.3 Compliance Assessment
+
+A Compliance Agent evaluates validated telemetry against regulatory thresholds and can consult stored compliance history from a data table to identify trends or recurring issues.
+
+## 1.4 Reporting and Notification Planning
+
+A Reporting Agent generates operator-friendly compliance summaries, while a Notification Agent determines whether Slack alerts should be sent and to which channel, based on severity.
+
+## 1.5 Persistence and Distribution
+
+The final output from the Coordination Agent is transformed for storage and distribution. Validated telemetry is stored, compliance alerts are prepared and stored separately, and a report email is sent.

Telemetry data arrives via webhook and is routed to a central Coordination Agent with persistent memory. Four specialised AI sub-agents operate in parallel: Grid Signal Agent (validates signals via Telemetry Validation Tool and parses structure), Compliance Agent (checks against compliance history), Reporting Agent (generates structured reports), and Notification Agent (triggers Slack alerts). Results flow into a Prepare Telemetry Storage node, then branch into three outputs, validated telemetry stored to a grid database, compliance alerts prepared and stored, and email reports dispatched. This eliminates manual grid monitoring, accelerates anomaly response, and maintains a continuous compliance audit trail across energy infrastructure. |

+    - Model: `gpt-4o`
+    - Temperature: `0.3`
+    - Connect it to `Notification Agent` as **AI language model**.
+
+20. **Create the Slack tool**
+    - Add a **Slack Tool** node named `Slack Notification Tool`.
+    - Configure:
+      - Authentication: `OAuth2`
+      - Send to: `Channel`
+      - Message text:
+        - `={{ $fromAI('message', 'Alert message to send to operators') }}`
+      - Channel field:
+        - `={{ $fromAI('channel', 'Slack channel ID for the alert', 'string', '#grid-ops-alerts') }}`
+    - Add **Slack OAuth2 credentials** with posting permissions.
+    - Make sure the bot is invited to the intended channels.
+    - If your Slack node requires actual channel IDs, use IDs rather than names.
+    - Connect it to `Notification Agent` as an **AI tool**.
+
+21. **Expose the notification agent to the coordinator**
+    - Connect `Notification Agent` to `Coordination Agent` as an **AI tool**.
+
+22. **Add the post-processing Set node**
+    - Create a **Set** node named `Prepare Telemetry Storage`.
+    - Connect `Coordination Agent` → `Prepare Telemetry Storage`.
+    - Add fields:
+      1. `timestamp` as string: `={{ $now.toISO() }}`
+      2. `validation_status` as string: `={{ $json.output.validation_status }}`
+      3. `generation_output_mw` as number: `={{ $json.output.generation.output_mw }}`
+      4. `generation_frequency_hz` as number: `={{ $json.output.generation.frequency_hz }}`
+      5. `load_consumption_mw` as number: `={{ $json.output.load.consumption_mw }}`
+      6. `storage_charge_percent` as number: `={{ $json.output.storage.charge_percent }}`
+      7. `anomalies` as string: `={{ $json.output.anomalies.join(', ') }}`
+   - Important: verify the Coordination Agent really returns data under `output`. If not, adapt expressions to the actual output shape.
+
+23. **Create the validated telemetry storage table**
+   - In n8n Data Tables, create a table for validated telemetry.
+   - Add columns matching the flattened fields above.
+   - Then add a **Data Table** node named `Store Validated Telemetry`.
+   - Set it to auto-map input data.
+   - Select the validated telemetry table.
+   - Connect `Prepare Telemetry Storage` → `Store Validated Telemetry`.
+
+24. **Create the compliance alert preparation node**
+   - Add another **Set** node named `Prepare Compliance Alerts`.
+   - Connect `Prepare Telemetry Storage` → `Prepare Compliance Alerts`.
+   - Add fields:
+     1. `timestamp` as string: `={{ $now.toISO() }}`
+     2. `alert_severity` as string: `={{ $json.output.validation_status }}`
+     3. `alert_type` as string: `compliance_check`
+     4. `description` as string: `={{ $json.output.anomalies.join('; ') }}`
+     5. `generation_mw` as number: `={{ $json.output.generation.output_mw }}`
+     6. `frequency_hz` as number: `={{ $json.output.generation.frequency_hz }}`
+   - Note: these expressions assume the original nested structure is still present. Because this node receives data from `Prepare Telemetry Storage`, you may need to adjust them if that node has already flattened or replaced the payload. In practice, this is one of the workflow’s likely points needing correction.
+
+25. **Create the compliance alerts storage table**
+   - Create a second Data Table for compliance alerts.
+   - Add columns for:
+     - timestamp
+     - alert_severity
+     - alert_type
+     - description
+     - generation_mw
+     - frequency_hz
+   - Add a **Data Table** node named `Store Compliance Alerts`.
+   - Enable auto-mapping.
+   - Select the compliance alerts table.
+   - Connect `Prepare Compliance Alerts` → `Store Compliance Alerts`.
+
+26. **Add the report email node**
+   - Create an **Email Send** node named `Send Report Email`.
+   - Connect `Prepare Telemetry Storage` → `Send Report Email`.
+   - Configure:
+     - Subject: `=Grid Compliance Report - {{ $now.format('yyyy-MM-dd HH:mm') }}`
+     - To: operator email address
+     - From: sender email address
+     - Format: `text`
+     - Body text: `={{ $json.output }}`
+   - Add email credentials:
+     - SMTP, Gmail OAuth2, or another supported provider
+   - If the body becomes `[object Object]`, change the expression to stringify or format the report text explicitly.
+
+27. **Create or verify required credentials**
+   - **OpenAI credentials** for all model nodes
+   - **Slack OAuth2 credentials** for the Slack tool
+   - **Email credentials** for the email node
+   - **Data Table access** in your n8n environment
+
+28. **Replace all placeholders**
+   - Replace:
+     - `<__PLACEHOLDER_VALUE__validated_telemetry_table__>`
+     - `<__PLACEHOLDER_VALUE__compliance_alerts_table__>`
+     - `<__PLACEHOLDER_VALUE__operator_email__>`
+     - `<__PLACEHOLDER_VALUE__sender_email__>`
+
+29. **Add optional sticky notes for maintainability**
+   - Add sticky notes for:
+     - prerequisites
+     - setup steps
+     - compliance logic
+     - reporting/notification
+     - storage/distribution
+   - This is optional for execution but useful for long-term maintenance.
+
+30. **Test with a sample telemetry payload**
+   - Send a POST request to the webhook with a realistic JSON body including:
+     - generation output
+     - frequency
+     - voltage
+     - load consumption
+     - power factor
+     - storage charge percent
+     - charge rate
+     - timestamp
+   - Confirm:
+     - the Coordination Agent can call sub-agents successfully
+     - structured parser output is valid
+     - Slack posts succeed
+     - email sends correctly
+     - rows appear in both data tables
+
+31. **Harden the workflow before production**
+   - Recommended improvements:
+     - Add an initial **Set** or **Code** node to normalize webhook input into a consistent string/object
+     - Add **IF** or **Code** nodes after the agent output to validate required fields before storage
+     - Serialize report content explicitly for email
+     - Use deterministic channel IDs in Slack
+     - Separate validation severity from compliance severity
+     - Consider adding error workflows or Error Trigger handling

+
+## Important implementation observations
+
+- The workflow depends heavily on AI agents returning a predictable structure, but only the Grid Signal Agent has an explicit structured parser.
+- The `Prepare Telemetry Storage` and `Prepare Compliance Alerts` nodes both reference `{{$json.output...}}`. This should be tested carefully because agent output formats in n8n can differ.
+- `Send Report Email` uses `{{$json.output}}` as plain text, which may not render well if the value is an object.
+- Slack channel selection may need real Slack channel IDs rather than names beginning with `#`.
+- The compliance severity currently appears to be derived from validation status rather than a dedicated compliance result, which may not reflect true regulatory severity.
