Preparing your site
What the hotel needs to arrange before a Wundermart shop can be installed. Share these requirements with the hotel early: internet and power must be ready on installation day.
Shop opening requirements (PDF): a version to send to the hotel.
Site
- Internet and power are ready and working according to the technical drawing. The hotel arranges this with its own internal or external team.
- The area is clean, accessible and fully prepared for installation.
- An electrician must be on site for all wiring. The installation team isn't allowed to do electrical work.
Payment terminal (POS)
- A wired internet connection within 1 metre of the terminal.
- At least 10 Mbit/s. Share a speed test result (e.g. speedtest.net) and the IP address with Wundermart.
- The kiosk uses the 192.168.1.x range internally, so the hotel network must hand out an IP address outside that range via DHCP.
- Confirm where the POS connection comes from: ceiling, wall or floor. The building partner then prepares a matching conduit.
Outgoing ports
The hotel's IT department or internet provider must not block these outgoing connections:
| Port | Protocol | Used for |
|---|---|---|
| 4500 | TCP | VPN |
| 500 | TCP and UDP | VPN (IKE) |
| 29811–29814 | TCP | Network management (Omada discovery) |
| 29810 | UDP | Network management (Omada discovery) |
| 9092 | TCP | Kafka (data exchange) |
Fridges
- One power outlet per fridge.
- With more than one fridge, each fridge on a separate electrical circuit.
Double-sided shelving unit (mid-floor)
- One power outlet per unit. Confirm whether power comes from the ceiling, wall or floor.
