17Watch the shop from your phone (new in 1.3)

The program has a small web server built in (no IIS, nothing to install). Turn it on and open its address on your phone: today / week / month sales, sales by hour, latest receipts, best sellers, running-low and expiring items, credit owed and the kitchen queue — refreshing every 30 seconds. View-only; you log in with the manager account.

On the shop Wi-Fi — 3 steps

1. Settings → Remote monitoring tab → tick Run the web server → Save & start. The address appears, e.g. http://192.168.1.35:8090/.
2. Press Allow in firewall and accept the Windows prompt (once). Without it phones on the Wi-Fi can't reach the till.
3. Open the address in the phone's browser (same Wi-Fi), log in with the manager name and password, and add the page to the home screen.

From outside the shop

Forward the port on the router (Port Forwarding) to the till PC. The Router port-forwarding help button explains it step by step, and Check from internet asks posmasr.com to try reaching your shop and tells you open / closed plus your public address. If your public IP changes, register a free DDNS name (No-IP, DuckDNS) and write it under “Public address”.

PosMasr Link — from anywhere, no router setup (3.2)

Egyptian ISPs now put most shops behind carrier-grade NAT (a shared address), so port forwarding no longer reaches the till and a static IP is no longer sold. PosMasr Link solves it: the till keeps one outgoing encrypted connection to our relay link.posmasr.com, and your phone opens https://link.posmasr.com/<code>/ from anywhere — mobile data, another Wi-Fi, another city. Nothing to configure on the router, no DDNS, no certificate.

1. Settings → Remote monitoring → scroll to PosMasr Link → tick Turn on PosMasr Link → Save. The status line says connected to link.posmasr.com within seconds.
2. Your address and its QR are right there: scan the QR with the phone camera (or Copy and send it to yourself), open it, and add the page to the home screen.
3. Log in with the same manager name and password as the dashboard — the Inventory and Manage pages work through it too.

HTTPS with your own SSL certificate

Tick HTTPS in the same tab and choose the certificate: a .pfx/.p12 file with its password (stored encrypted), or one from the Windows certificate store — the easy path with free Let's Encrypt certificates via win-acme, which also renews them automatically. Check certificate shows the name, issuer, expiry and whether it matches your public address. Anyone typing http:// on that port is redirected to https. The certificate must be for a domain name (your DDNS name), not an IP.

Something not working?

Press Run all checks: server → local → LAN → firewall → internet, with ✓/✗ and how to fix the first thing that fails. Advanced overrides (usually leave them): port, listen on one IP, LAN-only, allowed addresses, session length, request log.
