I bought Sensibo after trying a competitor product, Puck. After getting frustrated with getting Puck to work with my Senville mini split, I was hoping for a better experience with Sensibo. And to my pleasant surprise, Sensibo turned out to be a great choice! I had some setup difficulties trying to get the device to connect to my home wifi, but I went to the Sensibo website and followed the troubleshooting guide which helped. Once set up, Sensibo worked great with my system. While not a nest, it still does a great job of allowing me to remotely interact with my workshop's mini-split. The iOS app is easy to use and doesn't cause errors like the Puck app.——UPDATE—— I recently added a second Sensibo for another mini split for my new office building and am very satisfied. The Sensibo app makes it easy to manage both devices. Both work perfectly and I highly recommend these little devices.
