Facility

A facility represents a location or object where energy is consumed, or where real-time information such as temperature, CO2, or humidity is relevant. This is distinct from the actual measurement device (meter or sensor). Examples include a room, a building, or a piece of machinery. A facility is typically a static entity that remains consistent over time and is identified by a unique Facility ID. For instance, a building using both water and electricity might have separate Facility IDs for each utility (e.g., BUILDING1234-CW1 for water and BUILDING1234-EL1 for electricity). These IDs also denote a specific physical location.

Meter/Sensor

A meter or sensor is a device that measures energy consumption or environmental data like temperature, CO2, or humidity. This includes water meters, electricity meters, and temperature sensors. Each meter is assigned a unique Meter/Sensor ID for identification both locally and in transmitted digital data. These devices are installed at the aforementioned facilities to gather essential information (water consumption, room temperature) for purposes such as billing, statistical analysis, or control.

Infrastructure Product (Gateway)

To establish connectivity between meters/sensors and Elvaco Services for data transmission, a gateway is required. Similar to meters, each gateway is installed and assigned a unique Gateway ID.

Facility ID vs. Meter/Sensor/Gateway ID

The distinction between Facility IDs and Meter/Sensor/Gateway IDs is crucial because meters, sensors, and gateways are subject to change over the facility's lifespan. For example, a water meter may require calibration every 10 years, necessitating a replacement. However, the facility itself remains unchanged. By linking meter data to the Facility ID in a database, historical data remains intact even after meter replacements. If only the Meter ID were used, replacing the meter would result in the loss of historical data associated with the facility.

Conclusion

For effective metering project setup, two key pieces of information are required:

• Facility ID
• Meter ID

These IDs must be communicated to Elvaco Services to ensure proper operation and to define the scope of Elvaco's responsibilities. Any changes during the installation's lifetime must also be reported.

Wireless M-Bus Projects

Workspace Concept

Elvaco employs a "Workspace" concept, particularly beneficial in wireless M-Bus projects, to optimize gateway utilization and ensure high redundancy. A Workspace is a defined area where wireless M-Bus gateways provide coverage for installed meters.

Example:

Consider a wireless M-Bus project on Baker Street involving two adjacent buildings. Each building has two Elvaco Edge Wireless M-Bus Gateways. To maximize efficiency, only the gateway and meter IDs are required from the installation site. Elvaco Services automatically manages meter-to-gateway connections, eliminating the need for manual configuration. Linking gateways and meters to the Workspace is achieved through the work order form.

Wired M-Bus Projects

The Workspace concept applies to wired M-Bus projects as well. While the physical hierarchy is automatically populated, documenting the wired infrastructure is crucial for service and troubleshooting. This can be done by including the gateway ID supporting the wired meter in the “additional information” column. This documentation is essential for life-cycle management in wired M-Bus projects.
