The Smart Gateway is the latest in our product development. It provides a wide range of operating options and is on track for a 3rd quarter 2024 release. If interested, contact to be part of the early test and validation users.

This Gateway receives messages from the Wireless RF sensors and sends them to the JemRF Monitor servers.

The Smart Gateway has a built-in MQTT Agent that can publish sensor values to an MQTT Broker, providing a wide range of custom applications.

A simple firmware update button will automatically download and install firmware updates. USB port for offline updates.

The Smart Gateway setup uses the same internal WiFi configuration process as the WiFi Gateway and WiFi Sensor devices.
