In order to properly send data to Kontakt.io Cloud, Gateways have to be able to reach the internet. Right now, it's possible to connect through a 802.11b/g/n/ac WiFi network operating on the 2.4GHz/5GHz band.
The initial firmware release supports only WiFi authentication schemes based on pre-shared keys, like WPA(2) Personal. Support for certificate-based schemes (WPA2 Enterprise) is scheduled for later firmware updates.
For now, Gateways require DHCP to be enabled in your network. Static IP address assignments are not supported.
Gateways need to have access to certain remote resources if they are supposed to operate correctly, so a network firewall has to allow them to communicate with:
- Kontakt.io Cloud – this is where Gateways send and receive data & configuration updates.
- Amazon S3 servers – firmware binaries are stored there, so communication with these servers is necessary to allow firmware upgrades
- NTP servers – required for time synchronization. Gateways use these particular ones:
