Step 1 — Create PIN

On first power-on the device prompts you to create a PIN code. This PIN encrypts the master device key — it is required on every startup.

Step 2 — Connect to WiFi

After PIN creation the device starts an Access Point. Connect to it from your phone or computer. A captive portal opens automatically — select your WiFi network and enter the password. The device reboots after saving.

Step 3 — Web cabinet starts automatically

On first boot after WiFi setup, the web server starts automatically. Enter the device IP or mDNS address in your browser to complete registration.

After entering the PIN on every boot, you have a few seconds to select a mode by pressing a button. If nothing is pressed, WiFi mode starts automatically.

WiFi Mode — Web Server

After connecting to WiFi and syncing time via NTP, the device asks: enable web server?
