I'm very happy with the unit. Works very well so far and so quiet! The hardest part was getting the wifi connected. The instructions supplied did not work for me. What ended up working for me was sticking a paperclip into the reset button of the wifi module under the front cover for about 15-30 seconds and the green light started flashing. I then opened up smart life app on my (android) phone. Selected large appliances then in the top section I selected picture that looked like my mini split indoor unit with wifi beneath it. I entered my wifi password, hit next a few times and it connected! It now works with Google and Alexa. Hope that this might help someone else.
