Review on Sensibo Air: Apple HomeKit Certified Smart Air Conditioner Controller with 60-Second Installation, Energy Saving Features, and Compatibility with Google, Alexa, and Siri by Shawn Price

This product works as advertised. First, it doesn't turn the air conditioner on and off automatically. You need to go into settings and set "Climate Responsiveness" to turn it on. I found out the hard way that if you turn off the AC and leave the house, the climate response turns your AC on when you're not home, which happened for three days when I was on vacation and it cost me many dollars. $$s. The app also tries to sell you a monthly subscription to get access to your AC usage data, which annoys me.
