IT Overview

Infrastructure

Resource	Details
Domain	`pncfishandmore.com` — managed via ISPConfig
Web server	Apache on NetGrimoire (self-hosted Docker, `web.yaml`)
Email	MailCow + MXRoute relay
DNS	ISPConfig + internal Technitium
Accounting	Bigcapital (Docker on docker5, `accounts.netgrimoire.com`)

Digital Signage System

Three FireTV devices display live price board slides on in-store TVs. Each TV runs ScreenLite kiosk app loading an Apache HTML page, which fetches a Google Slides PNG export and refreshes it every 5 minutes via JavaScript.

TV Pages on Apache

File	Slide Deck	Purpose
`left.html`	Saltwater fish	Main fish price board
`right.html`	Secondary	Freshwater or secondary display
`inverts.html`	Invertebrates	Inverts price board

Google Slides Deck IDs

Deck	Slide ID
Left (saltwater fish)	`1S3j0K1QlWAtkjq73E73At3gz9vWp9vVr_yZswUHiyN8`
Right (secondary)	`1mWzgisxMQAFAhME9HXY_PEK0v_hIuQ4Md0PQS10ES8Q`
Inverts	`1nzunM4pQxqmW82_Ab0rrOsV4QuO8G5TVUDodplI_4tY`

PNG export URL format: https://docs.google.com/presentation/d/<ID>/export/png?sz=s1920

Use sz=s1920 for sharper text. If display looks soft, increase canvas size in Google Slides settings.

Critical: ScreenLite Does Not Respond to Meta-Refresh

ScreenLite ignores <meta http-equiv="refresh">. All TV page refreshes use JavaScript setInterval image src swap only:

setInterval(function() {
  var img = document.getElementById('slide');
  img.src = SLIDE_URL + '?t=' + Date.now();
}, 300000); // 300,000ms = 5 minutes

Force Immediate Refresh

Force-stop ScreenLite on the FireTV and relaunch. It reloads the Apache URL and picks up the latest PNG immediately.

Pending

Square webhook → Apps Script → Google Sheets automation (designed, not deployed)
"Push to Square" Apps Script button in Google Sheets
Store network documentation (router, AP, FireTV connections)
