CloudGate Probe NB-IoT

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 NB-IoT is ideal for asset monitoring use cases.

Data Sheet

The English datasheet, titled Option_CloudGateProbe_NB-IoT_Datasheet.pdf is available for download at the bottom of this page.

Configuration Options

The CloudGate Probe can be configured in three different ways:

1. MQTT
2. Programming Cable and Command Line Interface (CLI) Tool
3. Factory Configuration (Available for bulk orders, subject to Minimum Order Quantity)
   For this option, please fill in the CloudGate Probe Cellular Configuration Request Form at the bottom of this page and contact support@option.com or your sales contact.

We recommend configuring your CloudGate Probe devices via MQTT for ease of use. The CLI tool for manual configuration is available for download below. For larger projects, we offer factory pre-configuration services. Please contact your local representative for more information.

Recommended Hardware

For RS-485 configuration, we recommend using the following USB to RS485 dongle, which is the model we use internally: DFRobot FIT0737 USB to RS485 Dongle
