Communication Security
Features
The communication protocol
uses SHA-256 to ensure
cryptographic integrity of all
messages while supporting full
observability by utility firewalls.
The standard device uses an ISM
band RF protocol optimized for
fast telemetry.
Product equipped with the fiber-
optic package uses fiber-optic
communication between the
communication system and the
SmartValve devices
