The unit I ordered from Amazon never got to me, due to a bizarre Amazon fulfillment error, so I reordered directly from the manufacturer.I am impressed by the Sensibo Air. Setup was smooth, and was completely guided by the app. I was able to configure the device to work on my customized network, which walls off Internet of Things (IOT) traffic.The Sensibo app recognized my air conditioner's somewhat elaborate remote control from a single press of the remote's on/off button, and the app can do everything that the remote can do.The Apple HomeKit integration does what I need it to do, allowing me to turn the air conditioner on and off, set the temperature, and select fan-only mode, whether I'm at home or away.Notes:• The Sensibo app will not operate without continuous Internet access. After initial setup, it should be possible to use basic features of a home control app without external Internet access. Controlling the Sensibo Air through Apple HomeKit is a work-around.• I haven't checked whether the Sensibo Air complains if its external Internet access is revoked. Hopefully the device doesn't "phone home" unnecessarily. (I prefer to let Apple HomeKit broker commands when I am away from home, because HomeKit's security policy is well established.) I will update my review when I've tried tightening the firewall rules for my Sensibo Air.• The privacy implications of Sensibo's built-in geofencing feature (which can turn the air conditioner on when you arrive at home, and off when you leave) are unclear. The Sensibo app needs access to Location Services during the initial setup of the Sensibo Air, but works fine without location access after that (provided that the built-in geofencing feature is turned off). I will update my review when I've tried to create arrive/leave automations for the Sensibo Air at the Apple HomeKit level. (Here again, I prefer to let Apple HomeKit handle my location data, because HomeKit's privacy policy is well established.)• There's a silly user interface mistake in the Sensibo app. During setup, when you link the Sensibo Air to HomeKit, the Sensibo app displays a HomeKit QR code, as well as a manual setup code. Unless you have another iPhone or iPad, you can't scan the QR code. The manual setup code cannot be selected and copied, so you'd have to write it down on a piece of paper, switch from the Sensibo app to the HomeKit app, and manually type the code.In closing, the security and privacy concerns I've raised are common to most home control devices, and they shouldn't deter you. Setup was easy, the Apple HomeKit integration works, and the Sensibo Air is a major convenience. I'm looking forward to using it this summer!
