LinknLink App Agent+ Diagnostics for Smart Home Scenes

LinknLink App Agent+ Diagnostics for Smart Home Scenes

A scene can stop behaving as expected even when each device still appears in an app. The cause may be a renamed room, an unavailable Home Assistant entity, a changed schedule, an IR command that no longer reaches an appliance, or a presence condition that stays active longer than planned.

This guide shows how to use Agent+ as a structured diagnostic assistant inside the LinknLink App. The goal is to narrow the problem, test one reversible action, and keep manual control available while you review a scene.

Why Smart Home Scenes Fail After Setup

Names changed

A device, room, or Home Assistant entity was renamed after the scene was created.

One path is unavailable

The scene contains several devices, while one controller or integration is offline.

Conditions conflict

Time, occupancy, lux, temperature, or manual override rules prevent the action.

Start by separating device control from automation logic. If a device responds manually, investigate the trigger and conditions. If it does not respond manually, investigate the device, controller, network, or integration path.

LinknLink App Agent+ diagnostic workflow for smart home scene troubleshooting

What Agent+ Can Help You Review

Diagnostic area Useful question Evidence to collect Next tool
Device availability Which scene device is unavailable? Current app state and a manual control test. LinknLink device card or vendor app.
Room and device names Does the request point to the intended room? Room name, device name, and duplicate labels. LinknLink room settings.
Scene steps Which step completes and where does the scene stop? Trigger, conditions, action order, and delays. LinknLink scene editor.
Home Assistant Is the exposed entity available and current? Entity state, scene state, and integration health. Home Assistant entities, logs, and MQTT tools.
IR or RF action Does one stored command still operate the appliance? Controller state, profile, range, and manual remote result. eRemote HA, eHome HA, eMotion Pro, or eMotion Ultra controls.
Scope note: Agent+ can help organize the investigation using states and controls available to the app. Detailed broker logs, add-on failures, and protocol-level errors should still be checked in Home Assistant or the relevant integration.

Prepare a Clear Diagnostic Request

A useful request names the room, the expected outcome, the actual result, and the time it occurred. Avoid a broad message such as “my smart home is broken.” Give Agent+ a bounded problem that can be checked without changing unrelated scenes.

Include Example Why it matters
Room Living Room Prevents confusion when several devices have similar names.
Scene or device Movie scene and Living Room AC Defines the controls that should be reviewed.
Expected result Lights dim, curtains close, AC starts Creates a testable sequence.
Actual result Lights dimmed, AC did not respond Identifies the step that needs attention.
Recent change AC profile was relearned yesterday Points to a likely source without assuming the cause.

Step-by-Step Agent+ Diagnostic Workflow

Describe one failed outcome

Name the room, scene, expected action, and observed result. Keep other rooms outside the request.

Ask for a read-only review

Request a summary of the devices, states, scene steps, and conditions involved before approving changes.

Test the affected device manually

Use the device card or Home Assistant entity. A manual test separates connectivity from scene logic.

Review trigger and conditions

Check schedule, time zone, presence state, lux threshold, temperature range, and manual override.

Change one reversible item

Adjust one name, delay, condition, or command. Keep the original value in your notes.

Run a controlled test

Trigger the scene while you are in the room, confirm each step, and restore the prior setting when the result is not expected.

Prompt Patterns for Common Problems

Scene review:
Review the Living Room Movie scene without changing it. List the trigger, conditions, devices, delays, and any unavailable control. The lights worked at 8:10 PM, but the AC did not respond.
Presence review:
Check why the Office Focus scene ended while the room was occupied. Compare the presence state, vacancy delay, manual override, and Home Assistant entity availability.
IR or RF review:
Review the Bedroom Night scene. Test the fan command separately, confirm the selected remote profile, and do not change other devices.
Schedule review:
Explain why the Morning scene did not run today. Check the app time zone, schedule, enabled status, conditions, and unavailable devices before proposing one change.

Diagnose Presence-Based Automations

Presence automations often fail in two directions: a room is treated as empty while someone is still, or a room remains occupied after everyone leaves. Review placement, sensitivity, vacancy delay, room boundaries, and the entity exposed to Home Assistant.

  • Use eMotion Air where battery placement helps test a room before permanent installation.
  • Use eMotion Pro when the room also needs built-in IR control.
  • Use eMotion Ultra for 60GHz presence, built-in IR, and temperature/humidity context through its sensor cable.
Placement check: moving fans, curtains, reflective surfaces, nearby rooms, and an unsuitable vacancy delay can affect presence logic. Test the sensor state before changing several automations.

Diagnose IR and RF Actions

IR and RF scenes depend on a stored command, an available controller, and suitable signal reach. Test one command outside the scene, then review the scene step.

IR line of sight

Confirm the controller can reach the appliance and that the selected profile matches the model.

RF coverage

Confirm the learned RF action still works from the installed location and the receiver remains powered.

Manual fallback

Keep the original remote available while testing climate, shades, media, or other appliances.

Use eRemote HA for local IR workflows and eHome HA for compatible RF actions routed through Home Assistant.

Diagnose Home Assistant Entity Problems

When a scene uses Home Assistant, confirm the entity is available in Home Assistant before reviewing the app. An unavailable entity, renamed entity ID, disconnected MQTT device, or disabled integration can make the app-side scene appear incomplete.

  1. Open the entity in Home Assistant and confirm its current state.
  2. Run the related Home Assistant scene or service manually.
  3. Check whether the intended entity is exposed to the LinknLink App.
  4. Review MQTT, integration, or add-on logs when the entity is unavailable.
  5. Return to Agent+ with the confirmed entity state and test one scene step.

Example: A Living Room Scene Fails at the AC Step

Assume the movie scene dims the lights and closes the curtains, but the AC does not respond. The completed light and curtain actions show that the scene trigger ran. The investigation can focus on the AC step.

  1. Ask Agent+ to summarize the scene without editing it.
  2. Test the AC command from its LinknLink device card.
  3. If manual control fails, check the IR controller, profile, power, and line of sight.
  4. If manual control works, review the scene action, delay, condition, and device reference.
  5. Replace or relink that scene step, then run one controlled test.

Privacy and Change-Control Boundaries

Diagnostics should use the minimum information needed to solve the issue. Do not include door codes, alarm credentials, private network passwords, or personal messages in a troubleshooting request. Review changes before saving them, especially for locks, security systems, heating, cooling, and unattended appliances.

  • Request a read-only summary before asking for a modification.
  • Approve one reversible change at a time.
  • Keep manual controls available during testing.
  • Use Home Assistant logs for technical details that are not exposed to the app.
  • Record the original scene values before editing.

FAQ

What can Agent+ help diagnose in the LinknLink App?

Agent+ can help organize checks for supported device availability, room and device names, scene steps, schedules, presence states, Home Assistant entities, and IR or RF actions. Available detail depends on the connected device and integration.

Why does a smart home scene work manually but fail on schedule?

The device path may be healthy while the trigger, time zone, condition, or scene step is not. Test the action manually, then review the schedule and each condition separately.

Can Agent+ diagnose Home Assistant entities?

Agent+ can help review Home Assistant entities and scenes exposed to the LinknLink App. For integration logs, MQTT broker details, or add-on failures, continue the investigation in Home Assistant.

How should I troubleshoot an IR or RF scene?

Confirm the controller is online, test one command, check the selected remote profile, verify line of sight for IR or radio coverage for RF, and keep the original remote available while testing.

Should diagnostics change several automations at once?

Use one reversible change at a time. Record the original trigger, condition, and action, test the revision, and restore the prior version when the result is not expected.
