NFC (Near Field Communication) is a technology supported by some mobile phones (and tablets).

Using a mobile phone with NFC support and the NETIO Mobile 2 app, even a device that is powered off can be configured. The device will apply the new configuration as soon as it is powered on.
For example:
- NFC can be used to configure the WiFi connection parameters (network SSID + password) in the PowerCable MQTT 101x. When the PowerCable is powered on, it automatically connects to the specified WiFi network.
- NFC and the mobile app can be used to find out the IP address assigned to the installed WiFi device.
We prepared a Mobile Application NETIO Mobile 2 (Andriod & iOS) which supports NFC pre-config.
