In this article you're going to learn what reference meters are and how to configure them on the EMS platform.

Reference meters are the devices that, set up in a location, indicate their "meaning" in the site. In the case of Electricity this can be: Main device, HVAC, Lightning...
The reference meters allow you to aggregate, following the locations hierarchy and tags, the consumption of your sites, in order to perform portfolio analysis.
Setting up your reference meters can save you a large amount of time in the future, and can ease considerably your day-to-day job.
Energy Sources and Reference meters available
- Exported Energy
- Thermal (heating)
- Thermal (cooling)
- Compressed air volume
- Solar radiation
- Liquified natural gas energy (LNG)
For each of these Energy Sources you can create 1 or more Reference meter.
You can find the whole list of Reference meters by Energy Source available in Settings --> Preferences.
Remember that you can easily activate Reference meters that are not active by default in the same section under Settings --> Preferences.
Note: For Storage Reference Meters (Electricity) we have these two types:
Storage charge: energy entering the batteries - parameter 402
Storage discharge: energy coming from the batteries - parameter 452
If you need a Reference meter that is not yet available in DEXMA, contact us through the help center.
- To have a location or sublocation created
- To have data from any of the energy sources available in a device
- To have a device assigned to its corresponding location
Prior to this point, please make sure that you have enabled in Settings --> Preferences all the reference meters that you need to use.
When setting up a location, once you have assigned properly all its devices to it, you can, at some point, indicate which is the function of each device. Here's where the reference meters settings begin.
- Go to Settings --> Locations and, inside your location, go to the reference meters tab
- Go to the Energy Source that you want to setup the reference meter for.
- Select the device or group that is going to act as the reference meter. Check out the Tips and tricks section
- Click on save.
Note: Reference meters are available to be set up in Locations and Sublocations.
Use : what are they for?
The reason why Reference meters are so important is that they ease a lot the job of "identification" of the main devices to DEXMA. Once they have set up, your analysis job becomes much easier.
They are essential to:
- Create Dashboard and widgets by Zone or Template.
- Bill Simulation Reports.
- Advanced Analytics aggregated queries.
- Degree Days, automatically calculated by DEXMA
Tips and tricks
1. Assign as reference meters devices by hierarchy
You can select as a reference meter a device or group assigned to the location or a device or group that the location has access to by hierarchy, which means that it is assigned to a location or zone in a higher level of the hierarchy.
Example: Imagine that you want to share a Temperature device across multiple locations. You can assign it to the Global zone and then set this device up as the Temperature reference meter in all the locations under it. This is useful to calculate the Degree Days of several locations using the same temperature device.
