Product Features

  • Bi-directional connectivity between field devices and the RSTAR Affinity browser-based UI dashboard and mobile application.
  • Flexible connectivity including Ethernet, cellular, Wi-Fi, local radio LAN.
  • A pole mount is included with the gateway enclosure. An optional wall mount is also available.

The RSTAR Affinity gateway receives telemetry from RSTAR Affinity data loggers through LoRa radio. The data is forwarded to the RSTAR Affinity cloud server through wired internet, Wi-Fi, LTE, or to an on-premise server through local ISM radio.

The RSTAR Affinity gateway enables secure wireless communication between data loggers and the RSTAR Affinity browser-based dashboard and mobile application so sensor data can be transmitted and analyzed.

RSTAR Affinity

Built by our team of seasoned instrumentation experts specifically for geotechnical monitoring projects, the RSTAR Affinity system comprises loggers, gateways, secure communications for data telemetry, and mobile and desktop applications. Forget the headaches of improvised monitoring solutions cobbled together from different third-party vendors. RSTAR Affinity represents your complete industrial internet of things (IIoT) solution for reliable, real-time data flow from your work site to your desktop—all from a single source.

Speak with an Expert

I’m very happy with the quality of the instrumentation and technical support from RST, as always. They worked with us from the initial stages of the project to ensure that we were fully prepared and equipped to use the RSTAR network for the first time. They delivered everything within the tight project time frame to ensure that there were no delays on site, and the submersible tilt meters looked like new even after over twelve months of being submerged in Thames water!
