LWM2M integration
What is LWM2M?
Lightweight M2M is an open protocol from the Open Mobile Alliance (OMA) that is designed for addressing the needs of mobile low-power devices with very little compute power. LWM2M® is being adopted widely by telecom operators and is emerging as the standard protocol for device management and service enablement.
Why use LWM2M?
As the use of Internet of Things continues to grow so will the need to manage and use remote sensors and devices in areas with intermittent connectivity and situated far from power connections. LWM2M provides a standardized way to manage these devices and send telemetry data drawn in by the sensors quickly and cost effectively to the cloud.
LWM2M has been designed to reduce power and data usage for low-power devices, which are limited in processing power and bandwidth. The protocol is ideal when people or devices are a long way from power and need to use battery-powered local devices, have a SIM card and no power cord.
So sensors and devices can be managed centrally and viewed remotely, LWM2M defines a common language for the communication between devices and IoT platforms, such as Software AG’s Cumulocity IoT. With LWM2M, metadata (which describes the data) needed to understand the capabilities of a given device and interpret the data sent by the device is stored in a central repository in the cloud. This allows devices to minimize the transmission of data, so that only key data is sent. Saving bandwidth in particular for remote devices accelerates transmission, as well as reduces communication costs.
Sample use cases
Example uses include tracking shipper containers, cargo railways, farming where sensors monitor and optimize irrigation fertilization, smart cities, and water and energy metering. LWM2M is also used across telecommunications, the automotive industry, security devices, by utilities companies and in manufacturing.
Benefits of LWM2M
The Cumulocity IoT platform natively supports LWM2M as an IoT device management and service enablement protocol.
Self-service, plug and play
You can connect any LWM2M server and device without coding. Direct integration with LWM2M devices is quick and easy with our plug-and-play integration.
Remote management
Even though your devices are in hard-to-reach locations you need to be able to update the firmware and be aware of any issues. With its native integration, Cumulocity IoT provides firmware updates and monitoring capabilities out of the box and enables you to troubleshoot devices remotely.
Easy-to-use interface to map with the Cumulocity IoT data model
Cumulocity IoT’s device management allows you to define which data you want to receive from the device and at which frequency. Additionally, you can integrate data from the device into your IoT application’s domain model, allowing you to treat an LWM2M device in the same way as any other device connected to your Cumulocity IoT tenant.
