When this guide applies

Control app discovery is distinct from Bluetooth media.

Connection scope: Bluetooth. Symptom: The control app cannot find my device.

This is a documented check, not a diagnosis of your equipment. The model name does not confirm the selected input, mode, software or connected partner.

If your exact model or a required setting is unknown, use the “I don’t know” branch below. Do not apply a similarly named model’s instructions.

Checks and possible outcomes

Start at step-0. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.

step-0

Does ordinary Bluetooth music already work?

This checks a missing HEOS room, not Bluetooth pairing.

Look for: Confirm the stated prerequisite or observation; unknown is not a fault diagnosis.

step-1

Has home-network setup been completed?

Unknown setup needs the official HEOS setup procedure rather than a Bluetooth reset.

Look for: Confirm the stated prerequisite or observation; unknown is not a fault diagnosis.

step-2

Is the phone on the same intended home network?

Phone WiFi is required for HEOS control even when the speaker uses Ethernet.

Look for: Confirm the stated prerequisite or observation; unknown is not a fault diagnosis.

step-3

Inspect Rooms in HEOS

Select the intended registered speaker if present; do not change households or service accounts.

Look for: Perform only the stated check, then confirm whether it could be completed.
