An infrared (IR) controller for remote-controlled split air conditioners, with a temperature and humidity sensor, so you control the AC from the phone and by room conditions.
At a glance
- Works with any remote-controlled split AC.
- Temperature and humidity sensor.
- Connects over Wi-Fi.
How does smart AC control work?
IR controllers send the same commands as the AC remote by infrared, so they work with any remote-controlled split AC without any wiring to the unit. VRF / FCU gateways connect to the central AC system and link it to the smart home over Zigbee.

The critical point: line of sight and compatibility
An IR controller needs a direct line of sight to the AC in the same room. For VRF / FCU gateways, confirm compatibility with the AC system brand and model before ordering.
General notes
- One controller per room with a split AC.
- Place the controller away from heat sources so it reads room temperature accurately.
- Scheduling and occupancy control reduce consumption.
These are general notes
These points are general smart home installation practice, not taken from the NEXSMART datasheet. Electrical connections are made by a qualified electrician to the Saudi electrical code and the authority’s requirements.
Installation steps
- Place the controller where it sees the AC directly.
- Connect power and link it to the app.
- Pick the AC brand or learn the remote commands.
- Test on, off and temperature.
- Create schedules and scenes.
Common mistakes
- Placing an IR controller behind furniture or in another room.
- Ordering a VRF gateway without confirming system compatibility.
- Placing the controller near a sunny window.
Inspection and maintenance
Update the controller software from the app and keep its surface free of dust.
