Good! Now I have the new function code. I need to update the flows.json. The function code needs to be in a specific format - it needs to be escaped as a JSON string. Let me create the update using jq to properly update the JSON structure.

Actually, let me use a Python script to do this more reliably, as jq can be tricky with large strings and proper JSON escaping.


Now I'll update the flows.json with the new function code. This requires careful JSON manipulation:

with open('/home/mdares/.node-red/enhanced_work_order_buttons_function.js', 'r') as f:
    work_order_buttons_code = f.read()

# Update Machine cycles node
for node in flows:
    if node.get('id') == '0d023d87a13bf56f':
        node['func'] = machine_cycles_code
        node['outputs'] = 4
        print(f"✓ Updated Machine cycles function (ID: 0d023d87a13bf56f)")
        print(f"  - Changed outputs from 2 to 4")
        print(f"  - Added time tracking, cycle capping, anomaly detection")

    elif node.get('id') == '9bbd4fade968036d':
        node['func'] = work_order_buttons_code
        node['outputs'] = 5
        print(f"✓ Updated Work Order buttons function (ID: 9bbd4fade968036d)")
        print(f"  - Changed outputs from 4 to 5")
        print(f"  - Added stop categorization and session management")

# Write updated flows

Good, now let me run this Python script to update the function codes and output counts.


Bash

  - Added stop categorization and session management
✓ Updated Machine cycles function (ID: 0d023d87a13bf56f)
  - Changed outputs from 2 to 4
  - Added time tracking, cycle capping, anomaly detection

✅ flows.json updated successfully!
Note: You still need to add new nodes and wiring (next step)


Excellent! The functions have been updated. Now I need to:1. Add new MySQL nodes for the additional outputs
2. Wire the new outputs to these nodes
3. Add startup recovery flow
4. Add stop reason UI templateLet me continue with adding the necessary nodes to handle the new outputs.

Add MySQL nodes and wire outputs


Main tab ID: cac3a4383120cb57
Machine cycles position: x=640, y=400
Work Order buttons position: x=970, y=400
DB config ID: 00d8ad2b0277f906

✅ Added 3 new MySQL nodes:
   - State Backup DB (ID: 401f157d6e6c4c91)
   - Anomaly Tracker DB (ID: 8693ac11f0304215)
   - Session Manager DB (ID: eed296c8adc24f9a)

✅ Updated wiring:
   - Machine cycles output 3 → State Backup DB
   - Machine cycles output 4 → Anomaly Tracker DB
   - Work Order buttons output 5 → Session Manager DB

2. Add the stop reason UI template

   - Original: 152 KB
   - Updated: 191 KB (39 KB added)

### Implementation Files (Reference)
All files in `/home/mdares/.node-red/`:
- `complete_optimization_migration.sql` - Database schema
- `migration_for_beekeeper.sql` - Simplified SQL (used)
- `enhanced_machine_cycles_function.js` - New function code
- `enhanced_work_order_buttons_function.js` - New function code
- `startup_recovery_function.js` - Recovery logic
- `stop_reason_ui_template.html` - Stop reason UI
- `IMPLEMENTATION_GUIDE.md` - Detailed documentation
- `DEPLOYMENT_COMPLETE.md` - This file

---

## 🚀 Next Steps - TESTING

### Step 1: Restart Node-RED

```bash
# Stop Node-RED
pm2 stop node-red  # or however you run it

# Start Node-RED
pm2 start node-red
```

Or use the Node-RED restart option in the editor.

### Step 2: Verify Startup

After Node-RED restarts:

1. **Check for errors** in the Node-RED log/console
2. **Look for this message:** `[RECOVERY] Checking for existing session state...`
   - This means startup recovery is working
3. **Open Node-RED editor** and verify:
   - New tab "Startup Recovery" appears
   - Machine cycles node shows 4 outputs
   - Work Order buttons node shows 5 outputs
   - 3 new MySQL nodes visible

### Step 3: Basic Functionality Test

1. **Start a work order**
2. **Click START button**
3. **Let machine run 2-3 cycles**
4. **Check session_state table:**
   ```sql
   SELECT * FROM session_state WHERE session_key = 'current_session';
   ```
   - Should show cycle_count > 0
   - Should show operating_time increasing
   - tracking_enabled should = 1

### Step 4: Stop Reason Test

1. **Click STOP button**
2. **Verify:** Modal dialog appears with stop reason options
3. **Select** a planned stop (e.g., "Lunch break")
4. **Click Submit**
5. **Check stop_events table:**
   ```sql
   SELECT * FROM stop_events ORDER BY id DESC LIMIT 1;
   ```
   - Should show your stop with affects_availability = 0

### Step 5: Resume Test

1. **Click START again** (RESUME)
2. **Check production_sessions table:**
   ```sql
   SELECT * FROM production_sessions ORDER BY start_time DESC LIMIT 2;
   ```
   - Should show 2 sessions (original and resumed)

### Step 6: Cycle Cap Test

1. **Manually set cycle count to 95:**
   ```javascript
   // In Node-RED debug console or inject node:
   global.set("cycleCount", 95);
   ```
2. **Run 5 more cycles**
3. **At cycle 100:** Should see alert "Maximum 100 cycles reached"

---

## 🐛 Troubleshooting

### Issue: Node-RED won't start
**Symptom:** Errors about invalid JSON or syntax errors
**Solution:**
```bash
# Restore backup
cp /home/mdares/.node-red/flows.json.backup_20251121_185206 /home/mdares/.node-red/flows.json
# Restart Node-RED
```

### Issue: "Table doesn't exist" errors in MySQL nodes
**Symptom:** MySQL errors about missing tables
**Solution:** Re-run the migration SQL in Beekeeper (you may have missed a table)

### Issue: Stop reason prompt doesn't show
**Symptom:** Clicking STOP doesn't show modal
**Solution:** Check browser console (F12) for JavaScript errors. The UI template may need adjustment.

### Issue: Time tracking not working
**Symptom:** operating_time and downtime stay at 0
**Solution:**
1. Verify trackingEnabled is true: `global.get("trackingEnabled")`
2. Check Machine cycles function is receiving inputs
3. Verify state backup is running (check debug log every 10 cycles)

---

## 📊 Expected Results

After successful deployment:

### Database Tables

Imported nodes without a valid flow id

They have been added to a new flow called 'Recovered Nodes'.


The user is showing me an error message: "Imported nodes without a valid flow id. They have been added to a new flow called 'Recovered Nodes'."

This suggests they tried to restart Node-RED and there's an issue with the flows.json. Some nodes we added don't have proper flow IDs (the 'z' property that links nodes to tabs).

This is likely because when we added the Stop Reason UI template node, it might not have been properly assigned to a flow tab. Let me fix this issue.


I see the issue - some nodes weren't properly assigned to a flow tab. Let me fix this:


#!/usr/bin/env python3
import json

# Read flows.json
with open('/home/mdares/.node-red/flows.json', 'r') as f:
    flows = json.load(f)

# Find the main flow tab and home group
main_tab_id = None
home_group_id = None
home_tab_id = None

for node in flows:
    if node.get('type') == 'tab' and node.get('label') not in ['Startup Recovery']:
        if not main_tab_id:
            main_tab_id = node['id']
    if node.get('type') == 'ui_group' and 'home' in node.get('name', '').lower():
        home_group_id = node['id']
        home_tab_id = node.get('z')

print(f"Main tab ID: {main_tab_id}")
print(f"Home group ID: {home_group_id}")
print(f"Home tab ID: {home_tab_id}")

# Fix nodes without proper flow IDs

    # Skip tab nodes
    if node.get('type') == 'tab':
        continue

    # Fix nodes with null or missing 'z' (except config nodes)
    if node.get('z') is None and node.get('type') not in ['MySQLdatabase', 'ui_base', 'ui_tab', 'ui_group']:
        # If it's a ui_template for stop reason, assign to home tab
        if node.get('type') == 'ui_template' and 'Stop Reason' in node.get('name', ''):
            if home_tab_id:
                node['z'] = home_tab_id
                print(f"✓ Fixed Stop Reason UI template (assigned to tab {home_tab_id})")
                fixed_count += 1
        # Otherwise assign to main tab
        elif main_tab_id:
            node['z'] = main_tab_id
            print(f"✓ Fixed node {node.get('name', node.get('id'))} (assigned to tab {main_tab_id})")
            fixed_count += 1

# Also check for any nodes in Recovered Nodes tab and move them
for node in flows:
    if node.get('type') == 'tab' and 'Recovered' in node.get('label', ''):
        recovered_tab_id = node['id']
        print(f"\nFound 'Recovered Nodes' tab: {recovered_tab_id}")

        # Find nodes in this tab and reassign them
        for n in flows:
            if n.get('z') == recovered_tab_id:
                if n.get('type') == 'ui_template':
                    n['z'] = home_tab_id if home_tab_id else main_tab_id
                    print(f"✓ Moved {n.get('name', n.get('id'))} from Recovered to proper tab")
                    fixed_count += 1
                else:
                    n['z'] = main_tab_id
                    print(f"✓ Moved {n.get('name', n.get('id'))} from Recovered to main tab")
                    fixed_count += 1

    json.dump(flows, f, indent=4)

print(f"\n✅ Fixed {fixed_count} nodes with invalid flow IDs")
print("Node-RED should now load without 'Recovered Nodes' error")

Hmm, it didn't find the home group. Let me search more carefully for the ui_group and find what's causing the "Recovered Nodes" issue.


Let me check what's in the "Recovered Nodes" tab:


jq '.[] | select(.type == "tab" and (.label | contains("Recovered")))' /home/mdares/.node-red/flows.json

Find Recovered Nodes tab


jq '.[] | select(.type == "ui_group") | {id, name, z}' /home/mdares/.node-red/flows.json | head -20

Find all UI groups


{
  "id": "919b5b8d778e2b6c",
  "name": "Default",
  "z": null
}
{
  "id": "e1f2a3b4c5d6e7f8",
  "name": "Work Orders Group",
  "z": null
}
{
  "id": "e2f3a4b5c6d7e8f9",
  "name": "Alerts Group",
  "z": null
}
{
  "id": "e3f4a5b6c7d8e9f0",
  "name": "Graphs Group",
  "z": null
}


I see - the UI groups have `z: null` which is correct for config nodes. The issue is that Node-RED created a "Recovered Nodes" tab when it imported the flows, but that tab doesn't exist yet in the JSON. This means Node-RED already cleaned it up on restart.

The user might just be seeing this warning message on startup, but it should still work. Let me verify the Stop Reason UI node is properly configured:


jq '.[] | select(.type == "ui_template" and (.name | contains("Stop")))' /home/mdares/.node-red/flows.json

Find Stop Reason UI template
