Almost every Singapore home runs aircon — and most of it is controlled by a dumb remote. A smart aircon controller adds scheduling, geofencing (aircon off when you leave), temperature automation and voice control to the units you already own, usually for under $150.
What to look for in Singapore
- Works with your aircon’s IR remote (check compatibility before buying)
- Geofencing so the aircon turns off when everyone leaves
- Temperature/humidity automation — useful in a tropical climate
- Ecosystem support (Google/Alexa/Apple) and Matter where possible
- Optional room sensor for accurate temperature control

Sensibo is purpose-built for aircon: reliable IR control, genuine geofencing, climate reactions (turn on above a set temperature/humidity) and broad assistant support. The most polished experience.
Pros
- Excellent aircon-specific features
- Reliable geofencing
- Works with all major assistants
Cons
- Pricier than generic IR hubs
- Best features benefit from a subscription on some tiers
Best for smart-home fans
Aqara Hub (with IR)
If you already run Aqara, its IR-capable hubs control aircon and slot straight into automations with your motion and door sensors — and it’s Matter/HomeKit friendly.
Pros
- Great value within an Aqara home
- Ties aircon into wider automations
- Matter/HomeKit support
Cons
- Less aircon-specific polish than Sensibo
- Best with other Aqara gear
Best budget
SwitchBot Hub
An inexpensive IR hub that turns any aircon into a voice- and schedule-controlled unit. Add a SwitchBot thermometer for temperature automations.
Pros
- Very affordable
- Controls aircon + other IR devices
- Easy setup
Cons
- Automations less sophisticated
- Sensor is a separate purchase
Frequently asked questions
Will a smart controller work with my aircon?
Most controllers work with any aircon that uses an infrared remote — which covers the vast majority of split units in Singapore. Check the brand’s compatibility list for your model before buying.
Can it turn the aircon off when I leave?
Yes — geofencing uses your phone’s location to switch the aircon off when everyone leaves and on before you return, which is where most of the energy savings come from.
Do I need a separate temperature sensor?
Controllers with a built-in sensor can react to the room’s actual temperature/humidity. If yours doesn’t, adding a small sensor unlocks smarter automations.
