Sapient devices act as DHCP clients only and use DHCP to obtain their IP addresses. The devices do not expose any DHCP capabilities to other devices such as acting as a DHCP server.
Sapient devices communicate with the Sapient cloud using HTTPS and NTP. No advanced firewall configurations are required.
The network name and password you choose to provide your Sapient devices are encrypted and cannot be retrieved after the device has been configured for the network.
