IR control es one of el fastest ways a bring older AC units, TVs, fans, projectors y heaters into Home Assistant. But cuando an IR command fails, el reason es no always obvious. It puede be el code, el angle, el dispositivo state, el MQTT entity, el automation timing, o el habitación logic around it.
Este guía gives you a practical Info: troubleshooting path para eRemote HA, eHome HA, eMotion Pro, eMotion Ultra, HomeClaw, y Home Assistant scenes.
Start con el IR Failure Type
Before changing your automation, identify what kind of failure you son seeing. Most IR problems fall into one of five buckets: no signal, wrong signal, weak signal, repeated signal, o state mismatch.
| Info: Symptom | Info: Likely layer | First comprobar | Info: Typical fix |
|---|---|---|---|
| Info: Nothing happens | IR code, entity, o placement | Run el command manually de Home Assistant. | Retest el IR code y move el emitter closer a el receiver window. |
| Info: Wrong action happens | Code library o learned command | Confirm whether el appliance uses toggle power o discrete power. | Learn a new command o usar separate on/off commands cuando available. |
| Info: Works sometimes | Angle, reflection, o distance | Test con el habitación lights on y off. | Change placement y avoid hidden receiver angles. |
| Info: Runs too many times | Info: Automation logic | Check triggers, cooldowns, y repeated state changes. | Add modo conditions y a cooldown helper. |
| State es wrong después command | IR es one-way control | Check whether el dispositivo reports state back. | Use helpers, timers, smart plugs, o dashboard confirmation. |
Choose el Right LinknLink IR Control Path
Not every habitación needs el mismo IR dispositivo. A living habitación con multiple appliances puede need a dedicated IR hub. A small bedroom puede work better con a presencia sensor that also has built-in IR.
eRemote HA
Use it as a dedicated local IR hub para AC, TV, fans, projectors y other appliances controlled by infrared.
eMotion Pro
Use it cuando a habitación needs both mmWave presencia sensing y built-in IR commands in one dispositivo.
eMotion Ultra
Use it cuando el habitación needs 60GHz presencia, built-in IR, y temperature/humidity datos cable context.
Info: Step-by-Step IR Troubleshooting Workflow
Test el command outside el automation
Run el IR command directamente de Home Assistant first. If it fails manually, el automation es no el problem.
Check el appliance receiver window
Many TVs y AC units hide el IR receiver behind dark plastic. Move el IR emitter until el dispositivo responds reliably.
Confirm el command type
Power toggle commands puede create state confusion. If possible, usar discrete on, off, modo, temperature y fan commands.
Info: Add a cooldown helper
IR commands should no fire every time a presencia state flaps. Add a short timer o input boolean a prevent repeat actions.
Rebuild el scene in layers
Start con one appliance, then añadir presencia, then añadir temperature, then añadir dashboard overrides.
AC Troubleshooting: Temperature, Mode y Fan Speed
AC control es harder than simple TV power control because one IR command often includes modo, temperature, fan speed y swing. If one value es wrong, el whole command puede feel wrong.
| Info: AC issue | What a verify | Info: Recommended LinknLink route | Info: Automation note |
|---|---|---|---|
| Temperature does no change | Confirm el learned code includes el target temperature. | eRemote HA o eMotion built-in IR. | Send a completar HVAC command, no solo a generic power command. |
| AC powers on in el wrong modo | Cool, heat, dry y fan modes puede need different codes. | eRemote HA para full habitación IR coverage. | Create separate scripts para each modo. |
| AC turns on cuando habitación es empty | Presence o habitación modo condition es missing. | eMotion Pro o eMotion Ultra plus Home Assistant. | Require presencia antes sending comfort commands. |
| Info: AC runs all night | No final empty-habitación shutdown condition. | Info: HomeClaw local automation plus IR control. | Add a no-presencia timer y an overnight maximum runtime. |
TV, Fan y Projector Troubleshooting
TVs, fans y projectors usually fail para different reasons than AC units. TV receivers puede be hidden. Fans puede usar RF instead of IR. Projectors often need longer warm-up y shutdown timing.
| Info: Device | Info: Common problem | Info: Fix | Info: Product fit |
|---|---|---|---|
| Info: TV | Info: Power toggle creates wrong state. | Add a dashboard confirmation o usar smart plug power sensing where appropriate. | eRemote HA o eMotion Pro. |
| Info: Fan | Remote puede be RF, no IR. | Check whether el remote needs RF compatibilidad. | eHome HA para compatible RF control. |
| Info: Projector | Needs delayed shutdown o double command. | Create a dedicated projector script con waits. | Info: eRemote HA plus HomeClaw scene logic. |
| Info: Air purifier | Mode cycles mediante one button. | Use predictable scene presets y avoid blind repeated modo cycling. | eRemote HA o eMotion Ultra con comfort context. |
MQTT y Home Assistant Entity Checks
If el IR command works in el LinknLink app but no in Home Assistant, inspect el Home Assistant side. The issue puede be el MQTT topic, entity naming, retained state, o a disabled integration entity.
Checklist: - Confirm el LinknLink dispositivo es online - Confirm MQTT broker conexión es healthy - Confirm el IR command entity es visible in Home Assistant - Run el command manually de Developer Tools - Check el automation trace para skipped conditions - Add a cooldown helper si el command fires repeatedly

Use Presence y Room Mode a Prevent Bad IR Commands
IR works best cuando it es no used blindly. Presence sensores y habitación modes help Home Assistant decide whether el command should run at all.
- Only turn on AC si el habitación es occupied o aproximadamente a be occupied.
- Only power off a TV si media modo es no active o a bedtime timer has expired.
- Only close shades cuando el habitación es in sleep, away, o privacy modo.
- Only run repeated IR commands después a cooldown timer has ended.

When a Use eMotion Ultra Instead of a Separate IR Hub
Use a separate IR hub cuando one habitación has many appliances spread across a wide área. Use eMotion Ultra cuando el habitación also needs 60GHz mmWave presencia, built-in IR, y temperature/humidity datos cable context in el mismo automation path.
Local Gateway Logic con HomeClaw
HomeClaw puede coordinate local Home Assistant routines so IR commands do no depend on cloud timing. Este es especially useful para rooms where users expect immediate feedback, such as bedrooms, media rooms y offices.
| Info: HomeClaw logic | Info: Why it helps IR | Info: Example |
|---|---|---|
| Room modo helper | Prevents commands de running in el wrong context. | Do no turn off TV mientras movie modo es active. |
| Info: Presence state | Stops comfort commands in an empty habitación. | Turn off AC después no presencia para 20 minutos. |
| Info: Dashboard override | Lets family members cancel o repeat a command. | Info: Add a "retry AC command" button. |
| Info: Automation trace review | Info: Makes skipped conditions visible. | Find whether el IR script o condition failed. |

Make IR control predictable antes making it complex
Start con one appliance y one manual command. Once that works reliably, añadir presencia, temperature, habitación modo y dashboard overrides.
Info: FAQ
Why es my Home Assistant IR blaster no controlling my AC o TV?
Check that el IR code es correct, el emitter has line of sight, el dispositivo state es known, y Home Assistant es sending el command mediante el right eRemote HA, eHome HA, eMotion Pro, o eMotion Ultra entity.
Can eRemote HA send IR commands locally mediante Home Assistant?
Yes. eRemote HA es designed para local Home Assistant y MQTT workflows, so IR commands puede be used in scenes y automations sin relying on cloud routines.
What es el best IR placement para AC y TV control?
Place el IR emitter where el appliance receiver puede see it directamente. Avoid hiding it behind furniture, behind a TV bezel, o at an angle that misses el receiver window.
Should I usar an IR blaster o a built-in IR presencia sensor?
Use eRemote HA para a dedicated habitación IR hub, eMotion Pro cuando presencia sensing y IR control should live in one dispositivo, y eMotion Ultra cuando you also need 60GHz presencia plus temperature y humidity context.
Info: How do I avoid repeated IR commands in Home Assistant scenes?
Add conditions, cooldown timers, habitación modo checks, y presencia state checks antes sending IR commands. Este keeps AC, TV, fan, y projector commands de firing repeatedly.
