# Digital Signage Runbook
|
|
|
|
## Updating a Price
|
|
|
|
1. Open Google Sheets (master inventory)
|
|
2. Find the item row, edit price (col C), name (col B), or tank designator (col D)
|
|
3. Google Slides updates automatically
|
|
4. TVs pick up the change within 5 minutes — no further action needed
|
|
5. **Immediate update:** force-stop ScreenLite on that FireTV → relaunch
|
|
|
|
## Adding New Inventory
|
|
|
|
1. Add new row: SKU (A), display name (B), price (C), tank designator(s) (D)
|
|
2. Multiple tank designators are space-separated: `T4 T5`
|
|
3. Slides update automatically
|
|
4. Push to Square: currently manual via Square catalog CSV upload
|
|
|
|
## When an Item Sells — Manual Fallback
|
|
|
|
1. Remove the tank designator from col D of that item's row
|
|
2. Slides update automatically within a minute
|
|
3. TV picks it up within 5 minutes
|
|
|
|
## Google Sheets Column Reference
|
|
|
|
| Column | Field | Example |
|
|
|--------|-------|---------|
|
|
| A | SKU | `CLOWN-001` |
|
|
| B | Display name | `Ocellaris Clownfish` |
|
|
| C | Price | `29.99` |
|
|
| D | Tank designator(s) | `T4` or `T4 T5` |
|
|
|
|
## Troubleshooting
|
|
|
|
| Problem | Fix |
|
|
|---------|-----|
|
|
| TV showing stale price | Force-stop ScreenLite → relaunch |
|
|
| Image blurry/soft text | Add `?sz=s1920` to PNG export URL in HTML file |
|
|
| Slides not updating from Sheet | Check Apps Script in Extensions → Apps Script for errors |
|
|
| FireTV lost the URL | Re-enter Apache URL in ScreenLite settings |
|
|
|
|
## Square Webhook Automation (When Deployed)
|
|
|
|
Once live, the automation flow will be:
|
|
|
|
```
|
|
Square sale → Webhook POST → Google Apps Script Web App
|
|
→ Find item SKU in Sheet
|
|
→ Remove tank designator from col D
|
|
→ Slides auto-update → TV picks up within 5 min
|
|
```
|
|
|
|
**Status:** Designed, not yet deployed. Next step: configure Square developer dashboard webhook endpoint to the Apps Script URL and test with a real sale.
