Best Smart Controller for Mini-Split ACs in 2026

Mini-splits are fantastic for zoned comfort and efficiency, but the standard remote control experience still feels stuck in the past. 

Remotes can’t automate your routine, react when you leave home, or help you understand what your comfort is costing you. That’s exactly the gap a smart controller is meant to fill.

If you’re looking for the best smart controller for mini-split ACs in 2026, Klima is the most complete, mini-split-first option, built to work broadly, install quickly, and add real “smart home” capability without rewiring your HVAC. 

Why mini-splits need a dedicated smart controller (not a traditional thermostat)

Traditional smart thermostats like Nest and Ecobee are designed for central HVAC systems with low-voltage wiring. 

Mini-splits are different: they commonly use infrared remote commands or brand-specific control protocols, so they can’t be wired into a standard thermostat the same way. 

A smart controller like Klima bridges that gap by taking your mini-split remote to the next level and connecting to Wi-Fi, so you get app control and smart home automation without turning your install into a wiring project.

What makes Klima the best smart controller for mini-split ACs in 2026

A lot of devices can “turn your AC on from your phone.” Klima goes further by focusing on three things that matter in mini-split homes: setup, compatibility, and intelligence.

1. Fast, low-friction setup

Klima is designed to be plug-and-play. Klima's installation takes under five minutes, with no wiring, adapters, or tools.

2. Wide compatibility

Klima is built to be universally compatible, working with all ductless brands.

3. Premium build that actually looks like it belongs on a wall

Klima is designed with premium materials like aluminum exterior and mirrored glass, ensuring your controller is durable and lasts a lifetime. 

4. No subscription for core functionality

Some controllers in the market hold advanced features behind a paid plan. Klima comes with 0 subscription fees, all of the smart features offered are included as soon as you purchase a Boldr device. 

Klima’s smart features 

Klima’s “smart” value isn’t just remote access—it’s automation plus visibility.

1. Cost monitoring

Instead of guessing whether your mini-split use is “high,” Klima is designed to measure consumption in real time and provide monthly bill predictions, so you can connect comfort choices to actual cost. 

2. Smart scheduling 

Klima lets you build schedules around how you live—hour-by-hour, day-by-day—so you’re not running peak heating/cooling when nobody’s using the room. 

3. Remote access

Klima is built to give full control of your mini-split wherever you are, through the Boldr Energy app. 

4. Zonal control for multi-unit homes

Mini-splits shine when you treat rooms differently. Klima supports room-by-room control where a Klima and mini-split are located. 

5. Presence sensing 

Klima’s presence sensing technology is designed to turn the AC off when the last person leaves and get your home climate ready when the first person returns, one of the most effective ways to reduce waste without constantly adjusting settings. 

6. Multi-user control 

Homes aren’t run by one person with one phone. Klima supports shared use—others can use basic controls on the device, and household members or guests can join the app for access to all of Klima's smart features. 

Smart home integration

Klima is designed to fit into modern smart homes rather than exist as a standalone gadget. Klima is compatible with smart home devices like Google Home, Home Assistant, Amazon Alexa, Apple Home, and SmartThings. 

Conclusion

If you want the best smart controller for mini-split ACs in 2026, Klima is the strongest “set it up once, benefit every day” choice.
