How to Link Your AC to Alexa
There are various ways to achieve Alexa-controlled air conditioning:

Smart air conditioners are equipped with Wi-Fi connectivity and can be controlled remotely via a mobile app. They are typically mini-split, window, or portable units, designed to cool individual rooms or small spaces.
Many smart air conditioning systems are compatible with voice assistants such as Amazon Alexa, allowing you to control the system using voice commands.

Smart Thermostat for Mini-Splits
If you don’t have a smart air conditioner, you can opt for a smart thermostat for mini-splits, also known as a smart AC controller. It makes any ductless unit (mini-split, window, or portable AC) smart in just minutes. Cielo Breez smart thermostat for mini-splits allows you to control your unit using your smartphone or through smart voice assistants such as Alexa. Moreover, it equips your AC with various smart features such as scheduling, geo-fencing, energy usage tracking, and more.
Smart AC controllers, compared to smart ACs, offer advanced features and compatibility with a wide range of ductless systems, often outperforming smart ACs. Best of all, they come at a fraction of the cost of replacing your current AC with a new smart unit.
Your best choice to make any mini-split, window,
or portable AC smart. Enhance your comfort and savings.
