Users see their ACs grouped by site and room. For each AC, they see live data such as power status, room temperature, humidity, and device health. From their phone, they turn the AC on or off and change the temperature, fan speed, and swing.
The app tracks electricity use. It shows the estimated cost, active hours, and carbon emissions. Users also set timers that turn ACs on and off on selected days.
When an AC needs service, users book a technician in the app. They choose the service, apply a voucher, and follow the work order. After the job, they approve extra work, rate the technician, and download the service report.
The app is live on Google Play and the Apple App Store.
