Resumen del artículo
If your minisplit has a remote control, it can become smart today. The Cuby G4 smart controller learns your remote's signals and gives you full access from the Cuby app: turn it on or off, adjust the temperature, set schedules, and share control with your family — from anywhere.
The Sentry presence sensor completes the automation by turning off the AC when the room is empty, so you never have to think about it.
Every time you leave a room with the minisplit running, the compressor keeps working for no one. Multiplied across days, weeks, and months, those accumulated hours translate into a higher electricity bill and unnecessary wear on the unit.
The solution isn't buying a new AC or replacing any hardware: your current minisplit already has everything it needs to become smart.
What is a smart air conditioner
It's a conventional minisplit controlled from your phone instead of a remote. The unit stays the same — what changes is the controller that operates it.
The Cuby G4 smart controller does that job. It learns your unit's remote signals and replicates them through the Cuby app. It's compatible with any minisplit brand that uses an infrared remote control.

What you can do from the app with the Cuby G4
From the Cuby app, you control your minisplit as if you had the remote in your hand, from anywhere:
- Turn it on and off
- Adjust temperature, mode, and fan speed
- Set schedules by day of the week
- Share control with your family
The Cuby G4 smart controller provides the WiFi connection; your minisplit only needs an infrared receiver. If your remote can turn the unit on, off, and change the temperature, your unit already qualifies.
How to automate shut-off by presence
Controlling from your phone is useful, but automation is what turns a controllable AC into one that takes care of itself. The Sentry presence sensor detects whether anyone is in the room and turns off the minisplit after the space has been empty for a set amount of time — without the user having to remember.

It works autonomously without an internet connection. To configure wait times and review history from the Cuby app, it pairs with the Cuby G4 smart controller.
If you have more than one minisplit
Install a Cuby G4 smart controller on each unit and control them all from a single app, with schedules and rules per room. Useful in homes with multiple bedrooms, offices, or vacation rental spaces where leaving ACs running in empty rooms is the most common energy drain.
Conclusion
Your minisplit can be smart starting today without replacing the unit. The Cuby G4 smart controller gives you full control from the Cuby app, and the Sentry presence sensor turns it off automatically when the room is empty.
