Product Description
The CloudGate Probe is a compact, DIN rail-mountable metering device designed to connect various devices over Modbus (RS-485), M-bus, Digital & Analog Inputs to a Cellular (NB-IoT/LTECatM) network. This enables convenient remote monitoring of assets and buildings.
As a cost-effective and compact solution, the CloudGate Probe is capable of reading and transmitting data from nearly any meter to any IoT platform. Additionally, it can be used to adjust settings or control the state of actuators such as HVAC systems, control valves, relays, and more.
The CloudGate Probe Cellular is ideal for asset monitoring use cases.

Configuration Options
The CloudGate Probe can be configured using multiple methods:
- MQTT (over-the-air)
- USB-C Cable and Configurator Tool
The recommended configuration method is the DIN2 Configurator Tool, which can be downloaded from OPTION's FTP server. This tool allows you to create an extract of a device's configuration and import it into other devices, making it convenient to configure multiple CloudGate Probe units consistently and quickly.
During operation, we recommend configuring your CloudGate Probe devices via MQTT for ease of use.
