Klima Smart Controller review — Turn any room AC into a smart thermostat
If you rely on a ductless mini split, window unit, or standalone room air conditioner but hate juggling remotes and wasting energy, the Klima Smart Controller promises a simple fix: smart control for nearly any IR remote AC. In this review I test what Klima actually does, how easy it is to set up, and whether it can help you save money and stay comfortable—without rewiring or calling a technician.
Quick overview: what is the Klima Smart Controller?
The Klima Smart Controller is a compact, plug-and-play smart thermostat and controller that connects to your Wi‑Fi and learns the infrared (IR) signals from your AC remote. Once paired, Klima hands control to your smartphone through its app so you can change temperature, mode and fan settings, schedule heating/cooling, and apply automations to reduce energy waste.
- Compatible units: mini‑splits, window ACs, room ACs, and most heat pumps that use an IR remote with a display.
- No wiring: installs in under three minutes—no electrician required.
- Central control: one Klima per AC, all units manageable from the app.
- Price: $165 (available in Aluminium Silver and Graphite Grey).
How Klima works (in plain terms)
Klima listens to the infrared commands your AC remote uses. During setup the device “learns” those IR signals and replicates them on command. It connects to your home Wi‑Fi and pairs with the Klima app on your phone. From there you can control the unit remotely, create schedules, and use the smart automations Klima offers to avoid running the AC unnecessarily.
“Simplicity is the ultimate sophistication.” — Leonardo da Vinci. Klima aims for simple smart climate control without hardware changes.
Key features and real-world benefits
1. Universal IR compatibility
Klima is manufacturer-agnostic. If your AC has a remote with a display showing current settings, Klima can learn it.
- Benefit: No need to replace your AC or buy brand-specific controllers.
- Real-world: Works with older mini‑splits and modern window ACs alike—handy in rentals or homes with mixed brands.
2. Fast, no‑wiring installation
Plug Klima in, connect to Wi‑Fi, point your remote and let the device learn the commands. The company claims setup takes less than three minutes.
- Benefit: No electrician, no wall-mounted thermostat, no invasive installation.
- Real-world: Ideal for renters or DIYers who want smart control without altering the property.
3. Smartphone control and central app
Once configured, Klima lets you operate your AC from the phone—turn it on/off, change temperature, switch modes, and more. Multiple Klima units can be managed from one app.
- Benefit: Control each room from anywhere and coordinate multiple units centrally.
- Real-world: Turn the AC on remotely before you arrive, or switch off a unit you forgot to turn down.
4. Automations to reduce energy waste
Klima can run schedules and automations to avoid unnecessary cooling/heating. The maker cites up to 30% energy savings when used intelligently.
- Benefit: Lower utility bills without losing comfort.
- Real-world: Use schedules or presence-based automations to avoid cooling empty rooms or to reduce run-time during the day.
5. One device per AC, unified experience
You’ll need one Klima for each air conditioner, but all units talk to the same app for seamless multi-room control.
- Benefit: Scalable and simple to expand across a home or apartment.
6. Design and build
Klima ships in two finishes—Aluminium Silver and Graphite Grey—with a compact, modern design meant to blend with interiors.
- Benefit: Looks smart on a shelf or mounted near the AC without being obtrusive.
Who should consider Klima?
- Owners of mini‑split systems or window/room ACs who want smart control without replacing equipment.
- Renters and homeowners who want quick, non‑invasive smart climate upgrades.
- Anyone looking to reduce HVAC-related energy use with schedules and automations.
Limitations and what to watch for
- IR‑based only: Klima requires an infrared remote with a display. If your AC uses a proprietary wired controller or doesn’t show settings on the remote, Klima may not work.
- One per unit: You’ll need a separate Klima for each AC; costs add up for multi‑room systems.
- No hardwired control: Klima replicates remote commands rather than replacing a wall thermostat for centralized HVAC systems.

Final verdict — should you buy the Klima Smart Controller?
Klima delivers exactly what it promises: a practical, easy way to make IR‑remote air conditioners smart. If you run mini‑splits, window units, or room ACs and want remote control, scheduling, and basic automations without rewiring, Klima is a strong, budget‑friendly option.
Buy Klima if you:
- Have one or more IR remote‑controlled AC units and want true smartphone control.
- Rent or don’t want to alter walls or wiring.
- Want to reduce AC energy use through scheduling and automations.
Skip Klima if you:
- Use central HVAC that requires a hardwired thermostat.
- Your AC uses a non‑IR or displayless remote that Klima cannot learn from.
- You need a single controller to manage multiple internal zones without installing one device per unit.
Final thoughts
For what it is—a wireless, IR‑learning smart controller—the Klima Smart Controller is simple, effective, and well suited to renters and homeowners with individual AC units. It won’t replace a full home HVAC overhaul, but it will turn your existing units into connected, smarter devices that can save energy and make daily life easier.
Have specific compatibility questions?
Klima is manufacturer-agnostic but needs an IR remote with a display. If your AC meets that requirement, the likelihood of compatibility is high.
