Chapter 10 - Advanced Driver Metrics

10.1. Introduction

Response Node with the official release of 2021.2 brings you the ability to collect advanced DALI2 driver data across multiple OR user interfaces. As part of this release the Organic Response advanced driver metrics will initially be made available through the Response App.Before we introduce the feature and how to collect this information lets first have a brief look into what advanced drivers metrics are.

10.1.1. Advanced Driver Metrics

DALI alliance has recently introduced D4i in the DALI standard for intelligent and IoT ready luminaires. With this new standard, the compliant drivers will have the capability to store as well as report energy and diagnostic data in a standard format. Thus the Response Node is an ideal platform from which to collect and report this information directly to users using the Response App.

As part of this release Response App will be the only way to access driver metrics, however, since the Response Node is made capable to report it to gateway, in future these may become available through other OR solutions such as Response portal or the Response API.

10.1.2. Pre-requisites

In order to collect and report this data, drivers must be capable of collecting this information as well as reporting it over DALI. Once the drivers are made capable then an Response Node connected over DALI will be able to present this information through the Response App as a result of query.

10.2. Feature

As part of OR 2021.2 product release we have included the collection and reporting of some initial, important parameters. The list of advanced driver metrics exposed and made available over OR solution includes the following,

DALI Identifier

Description

DALI 251

  • Luminaire identification, i.e. model name.

DALI 252

  • Load side energy (ActiveEnergyLoadside) - energy over an interval, measured in Wh.

DALI 253

  • LightSourceOnTime - the total cumulative “on” time for the light source.

In order to enable access to the values for each of these fields, a new page and query function has been introduced in the Response App.

10.2.1. How to Access Metrics

In order to access advanced driver metrics you will need to have access to the Response App with a configurator level on your smart device (Android and iOS). Once logged in you can access the advanced driver metrics following the below pathway,

  1. Go to “Configure Nodes”.

  2. Select the Response Node connected to compatible D4i driver.

  3. Click on “Configuration“ at the bottom right corner after making your selection.

  4. Scroll down and select “Advanced Driver Metrics“.

  5. Click on “Query”.

The Response App will, in the background, process the request for the selected Response Node and report the information exactly as it’s being reported by the driver from within the last hour. If the driver has information available then the query results will be displayed on screen under Advanced Driver Metrics.

The Response Node will continuously query the driver metrics every hour. Thus the query will result in the information reported from the most recent query.

Here are a few screenshots including an example response from successful query

10.2.2. Metrics Explained

The metrics when queried will result in the values returned to Response Node as stored in the driver. Further explained below,

  1. The model name - may be blank or not displayed at all if the luminaire manufacturer hasn’t set any identification for the luminaire. An example without model name is shown in the sample response above.

  2. LOT - Will show the light on time displayed in hours e.g. LOT = 55 would mean that the light source has been on for 55 hours.

  3. AEL - Active Energy Load-side shown in Watt Hours.
