Quick terms before the comparison

Fan coil: the indoor aircon unit on the wall or ceiling, not the outdoor compressor.

IR: infrared, the same invisible remote-control signal your Mitsubishi handheld remote uses.

Line of sight: the controller must be able to see the aircon receiver, roughly like pointing a remote at the unit.

Apple HomeKit: Apple's smart-home layer inside the Home app, Siri, and automations.

Matter: the newer smart-home standard that lets devices appear across Apple, Google, Alexa, and other ecosystems, but each app may support different features.

Aqara Hub M3: mainly the control hub for Aqara sensors and switches. Its aircon control is an extra feature, not its only job.

MyME: Mitsubishi Electric Singapore's own app for controlling supported Starmex systems.

Wi-Fi interface: an add-on module fitted to the aircon so it can talk to Mitsubishi's app.

Native two-way integration: the aircon and app talk both ways, so the app should know the real mode, temperature, and power state.

Desync: the app thinks the aircon is in one state, but the actual aircon is doing something else.

Cloud control: the command goes through the internet first. Local control can work inside the home network even if the internet is down.

DB/router area: the utility cabinet where many BTO owners place networking gear. It is usually a poor spot for sending remote-control signals into rooms.

The short answer

For a master bedroom, kids room, and living/dining setup, I would choose:

Sensibo Air per fan coil as the default Apple-first path

Aqara Hub M3 for the Aqara smart-home layer

Aqara M3 as a possible one-room AC trial only if line of sight and Apple Home exposure are proven

I would not assume one Aqara hub in the DB/router area can control every Starmex fan coil. IR needs line of sight, and Aqara says Hub M3 can expose only one AC device to Matter, with functionality varying by Matter app.

Mitsubishi MyME is native, but not Apple Home

Mitsubishi Electric Singapore's MyME path is worth asking the aircon installer about.

But for this Apple Home plan, it is not the clean family interface.

Mitsubishi Singapore's own MyME FAQ says the app controls Mitsubishi Electric air conditioners by smartphone, requires the official Wi-Fi interface, and currently supports Starmex. It also says direct local control without internet is not possible, third-party interfaces are not supported for MyME, Google Home and Alexa are not currently supported, and physical remote changes may take up to 5 minutes to sync through the cloud.

That makes MyME the most native Mitsubishi route technically, but not the Apple Home answer.

Why Sensibo Air is the cleaner multi-room path

Sensibo Air is easier to reason about because the architecture is explicit:

one Sensibo unit per air conditioner or heat pump

clear IR line of sight to the indoor unit

Apple HomeKit compatibility

built-in temperature and humidity sensing

optional Sensibo Room Sensor support

simple scaling across rooms

For this home, that means:

master bedroom: 1 Sensibo Air

kids room: 1 Sensibo Air

living/dining: 1 Sensibo Air per fan coil

There are still caveats. Sensibo is still IR control, not a native two-way Starmex integration. If someone uses the Mitsubishi remote, the app state can become less authoritative. Sensibo's HomeKit support exposes the important aircon behavior, but not every advanced Sensibo feature; support material notes that fan levels and swing are not exposed in HomeKit.

Still, the mental model is clean. If I want room-by-room Apple control, I place a controller in each room.

Where Aqara Hub M3 fits

Aqara Hub M3 is attractive because it can sit at the center of the broader Aqara setup: sensors, buttons, switches, locks, Zigbee, Thread, Matter, and some IR control.

But the aircon caveat is important.

Aqara says M3 can expose an IR-controlled AC to Matter when paired with an Aqara climate sensor, but only one AC device can be exposed to Matter, and functionality can vary by Matter app.

That makes it risky as the whole-flat Starmex strategy.

Where I would use M3:

Aqara sensors

Aqara scene buttons

Aqara switches

Matter/Thread/Zigbee bridging

maybe one living/dining AC if the hub has line of sight

Where I would not use it by default:

as the only plan for master bedroom, kids room, and living/dining aircon control

Sensor placement matters

For any IR climate controller, do not place the temperature sensor in a nonsense location.

Avoid:

direct fan-coil airflow

direct sun

windows

behind curtains

inside carpentry

kitchen heat

TV/console heat

Place it where the room actually feels occupied. In the kids room, keep logic conservative. Use comfort alerts and gentle schedules, not aggressive occupancy-based cooling.

The desync problem

IR control has a built-in weakness: the aircon is not always reporting its true state back to the controller.

If someone uses the original Mitsubishi remote, the smart controller may not know everything that changed. Some products try to detect remote commands, but that is still not the same as a fully native two-way integration.

My rule:

keep the Mitsubishi remote as fallback

train the household to use one normal daily control path

do not build safety or comfort assumptions on perfect AC state

avoid automations that assume fan speed, swing, and mode are always known

Renovation decisions

Before electrical signoff, I would plan:

reachable power for each IR controller

line of sight from controller to fan coil

temperature sensor placement away from airflow

bedside/scene button logic for Sleep, Wake, and All Off

remote storage so the original remote is always available

My recommendation

For this Apple Home-first BTO:

Use Sensibo Air per Starmex fan coil if multi-room Apple control matters.

Use Aqara Hub M3 for the Aqara ecosystem, not as the assumed whole-flat AC controller.

Trial M3 for one living/dining AC only if line of sight is good and Apple Home exposure is proven.

Treat Mitsubishi MyME as a manufacturer app path, not the main Apple Home interface.

Keep every room usable through the original aircon remote.
