Device Groups

A single Everything Presence Pro Grid sensor may not cover a whole room. Device Groups let you combine 2 or more physical sensors into a single virtual device in Home Assistant — so automations can target "Master Bedroom" without ORing multiple sensors by hand.

Device Groups Listing Page.

A device group exposes:

  • One occupancy binary sensor that is on if any source sensor's occupancy is on.
  • The same for static presence, motion presence, target presence, and mmWave presence — each only created if at least one source has that entity enabled.
  • One Rest of room binary sensor, combined across all source devices.
  • One binary sensor per zone (1–7) on each source — passing through with the zone's original name.
  • One binary sensor per merged zone you define — for combining named zones from different sources into a single sensor.

Every sensor can be turned off in the editor if you don't want it in the group. If a source goes offline, the device group ignores it. The helper becomes unavailable only when every source is unavailable.

Creating a device group

  1. Open the Everything Presence Pro Grid panel and switch to the Device Groups tab.
  2. Click Add a device group.
  3. Enter a Device name; optionally choose an Area to assign the virtual device (and its source devices) to.
  4. Under Devices, toggle on the sensors to include. Each shows whether it is Online, Offline, or no longer exists.
  5. Under Sensors, every sensor from the included devices is on by default — toggle off any you don't want. Presence sensors show which devices provide them and flag any device where the sensor is disabled in HA.
  6. To combine named zones from different devices into a single binary sensor, switch the Sensors list to Merge zones, tick two or more zones, give the merged zone a name (e.g. "Bed"), and click Merge. The merged zone appears in the list and becomes a single binary sensor.
  7. Click Save.

Device Groups Editor.

The new virtual device appears under Settings → Devices & Services → EPP Grid with all its aggregated entities.

Editing or deleting

Each device group in the list has a ⋮ menu:

  • Edit reopens the editor — change the name, devices, area, sensors, or merged zones and Save.
  • Delete removes the group and all its helper entities.

A merged zone has its own ⋮ menu inside the editor for editing or removing just that zone.

What happens when…

Event Behavior
A source device goes offline It's ignored. Helper still tracks the rest.
You delete a zone on a source If it was in a merge group, the group keeps its definition but the entity goes unavailable. Add another zone to the group or delete it.
You rename a source device or zone Display names update; the helper's entities keep their unique IDs and don't break.
You remove a source device entirely The group keeps it in its source list but shows it as unavailable, and the helper ignores it. Edit the group to remove or replace it.
You need one device's rest-of-room separately The group exposes a single combined Rest of room sensor. Use the physical device's own Rest-of-room entity for per-device tracking.
