Who it’s for

Facility managers, building automation engineers, and workplace managers ask “what is the illuminance in this space right now?” They need a compact, space-efficient card that fits into multi-zone lighting dashboards without dominating the layout.

What it does

A sensor reporting illuminance = 350 lx displays the reading in a horizontal card whose label and value sit side by side, color-coded by band: dark gray for Dim (0–100 lx), orange for Low (100–300 lx), dark orange for Moderate (300–500 lx), and red for Bright (above 500 lx).

  • Horizontal layout fits more zones per row on a multi-zone lighting dashboard
  • Live illuminance reading in lx with automatic color coding across four bands
  • Shows one sensor’s reading per widget; tile multiple widgets to monitor all zones at a glance

How to set up

Data keys

KeyRoleTypeDescription

The widget ships with a simulated function datasource key labeled Illuminance, so it draws random values until you point the datasource at a device and rename the key.

To point it at your own device: open the dashboard in edit mode, open the widget’s Datasources, pick the entity or entity alias, and replace the function key with the key your device reports.

How to customize

  • To change the band thresholds — open the widget settings and adjust the boundaries to match the lighting standard for your space.
  • To change the band colors — edit the color for each level in the widget settings.
  • To rename the units label — change the Units field in the widget settings if needed.

Tips

  • Use the horizontal layout to fit more zones per row when building a whole-floor lighting overview for a post-occupancy evaluation; pair with the standard card for key task areas that require closer monitoring.
  • Placing horizontal cards for illuminance and occupancy side by side on the same row lets building engineers quickly verify that the lighting control system is responding correctly to sensor inputs.
  • For a commissioning sign-off, a row of horizontal illuminance cards across all monitored zones gives the handover team an instant multi-zone compliance check.
