Home Assistant Remote Control Guide: IR, RF, MQTT, eRemote HA and eHome HA
A Home Assistant remote-control setup is not just a replacement for a plastic remote. It is the bridge between old appliances and local automation. The right remote hub can control an AC, TV, fan, projector, RF shade, fireplace, or receiver while keeping the decision logic inside Home Assistant.
This guide explains when to use eRemote HA, when to use eHome HA, and how to pair remote control with HomeClaw, eMotion Pro, and eMotion Ultra.
Start with the Signal: IR, RF or MQTT?
The first question is not which brand to buy. The first question is which signal your appliance uses. An IR remote needs line of sight and usually controls AC, TV, fan, soundbar, or projector equipment. An RF remote can work through some obstacles and often controls shades, outlets, garage devices, or regional appliances. MQTT is the Home Assistant-friendly message layer that makes those commands easier to automate locally.
IR
Best for AC, TV, fan, projector, soundbar, heater, purifier, and appliances that already use infrared remotes.
RF
Best for compatible RF shades, outlets, switches, and legacy devices where line of sight is not practical.
MQTT
Best for Home Assistant users who want local automation, clear topics, and repeatable commands without cloud scenes.
eRemote HA vs eHome HA
Both products can belong in the same Home Assistant system, but they solve different remote-control problems. Treat them as complementary layers instead of competing replacements.
| Need | Choose | Why | Best room example |
|---|---|---|---|
| Local IR control for AC, TV, fan or projector | eRemote HA | Dedicated IR remote hub for Home Assistant and MQTT workflows. | Bedroom AC, living room TV, office fan, media room projector. |
| RF remote automation | eHome HA | RF hub path for compatible RF devices where IR is not the right signal. | RF shades, outlets, legacy RF receivers, regional remote-controlled devices. |
| Presence-aware IR scenes | eMotion Pro or eMotion Ultra | Combines mmWave presence with built-in IR so one room device can detect and command. | Desk, bedroom, TV corner, comfort automation room. |
| Private Home Assistant gateway | HomeClaw | Keeps local automation context, private AI direction, and gateway logic close to the home. | Whole-home local control and remote automation planning. |
| Visible manual override | iSG Display Max | Gives family members a dashboard for room mode, appliance state, and override. | Family room, guest room, shared living room. |
When eRemote HA Is the Better Fit
Choose eRemote HA when the appliances you care about use infrared remotes. The most common Home Assistant use case is AC automation, but IR is also useful for TVs, fans, air purifiers, heaters, projectors, and some audio devices. The benefit is not just remote replacement. The benefit is turning a remote command into a local automation step.
- Use it when the appliance has an IR remote and the hub can be placed with good line of sight.
- Use it when the room needs repeatable Home Assistant MQTT commands.
- Use it when AC or fan rules should be combined with presence, temperature, or time-based helpers.
- Use it when a room still needs a manual fallback through dashboard buttons.
When eHome HA Is the Better Fit
Choose eHome HA when the device is controlled through compatible RF instead of IR. RF can be useful for devices where line of sight is inconvenient or where the original remote is clearly radio-based. This makes eHome HA a better candidate for certain shades, outlets, receivers, or older regional smart home devices.
Before building a large RF automation plan, test the exact device and command behavior. RF ecosystems are more varied than IR TV or AC remotes, so the best workflow is to confirm the device, map a few reliable commands, and then connect those commands to Home Assistant scenes.
How Presence Sensors Improve Remote Control
A remote hub can send commands, but presence tells Home Assistant whether the command should happen. This is where eMotion Pro, eMotion Ultra, and eMotion Air become useful. For example, do not turn on the office fan if the room is empty. Do not shut off the AC the moment someone sits still. Do not switch TV input unless the media scene is active.
Rule of thumb: remote commands should be event outputs. Presence, mode, temperature, humidity, and manual override should decide when those outputs fire.
Scenario Matrix: Which Remote-Control Path Should You Use?

| Guest or vacation mode | HomeClaw + remote hub | Mode helper + time window + occupancy status. | Vacation mode automation |
Build a Local Remote-Control Stack
Inventory every remote
Separate IR appliances from RF appliances. Put AC, TV, fan, projector, purifier, shades, outlets, and receivers into separate rows before you buy anything.
Choose the right hub per signal
Use eRemote HA for IR-heavy rooms and eHome HA for compatible RF devices. Do not force one signal type to solve the other.
Add Home Assistant helpers
Create helpers such as living_room_media_mode, bedroom_comfort_mode, guest_mode, away_mode, and manual_override.
Pair commands with presence
Use eMotion sensors to decide whether a command should run, not just whether a button was pressed.
Keep dashboard override
Show key remote actions on iSG Display Max or a Home Assistant dashboard so family members can stop or repeat a command.
Example MQTT Topic Plan
Your exact topic names depend on your setup, but the naming pattern should stay readable. The goal is for a future operator to understand what the command does without opening the automation editor.
living_room/remote/tv_power living_room/remote/tv_input_hdmi1 bedroom/remote/ac_cool_24c bedroom/remote/ac_fan_low office/remote/fan_power shade/remote/living_room_open shade/remote/living_room_close Automation rule: IF room_presence is on AND comfort_mode is normal AND manual_override is off THEN publish the correct local remote command
Common Mistakes to Avoid
| Mistake | Why it fails | Better approach |
|---|---|---|
| Buying one hub before checking signal type | IR and RF are different paths; one does not automatically replace the other. | Inventory remotes first, then choose eRemote HA or eHome HA. |
| Sending commands without presence context | The room may be empty, asleep, or under manual override. | Use presence, mode helpers, and delay logic before commands. |
| Hiding remote actions from users | Family members cannot understand or recover from automation mistakes. | Add dashboard buttons and visible room mode status. |
| Replacing every remote on day one | Too many commands make troubleshooting difficult. | Start with one high-value room and expand after stable testing. |
| Depending only on cloud scenes | Cloud delays can make remote control feel unreliable. | Use local Home Assistant helpers and MQTT command paths. |

LinknLink App Remote Control FAQ
Can the LinknLink App control IR and RF scenes remotely?
Yes. Use the LinknLink App as the room-control layer, then connect eRemote HA for IR appliances, eHome HA for compatible RF devices, and Home Assistant helpers for local automation logic.
Where should I link users who want room dashboards?
Send them to the LinknLink App Room Dashboard Guide, then route product intent to eRemote HA, eHome HA, HomeClaw, eMotion Ultra, and iSG Display Max.
FAQ
Is eRemote HA an IR blaster for Home Assistant?
Yes. eRemote HA is designed as a local IR remote hub for Home Assistant and MQTT workflows, making it useful for AC, TV, fan, projector, purifier, and other IR-controlled appliances.
When should I use eHome HA instead of eRemote HA?
Use eHome HA when the target device uses compatible RF remote control rather than infrared. RF and IR solve different appliance-control problems.
Can Home Assistant replace a Logitech Harmony Hub?
Home Assistant can replace many Harmony-style room scenes when paired with a local IR hub, RF hub, dashboard buttons, and presence-aware automation logic. Device compatibility still depends on the appliances and commands you need.
Do I need presence sensors for remote control?
You can send remote commands without presence sensors, but presence makes automations safer and more useful because Home Assistant knows whether a room is occupied before sending a command.
How does HomeClaw fit into a remote-control setup?
HomeClaw acts as the local Home Assistant gateway layer, keeping remote-control logic, private AI direction, MQTT automations, and room context closer to the home.
Setup note: always test the appliance command before building a large automation around it. IR placement, RF compatibility, and manual override matter more than a long automation list.
