I've got 2 Ambis. They worked great in 2019 but since 2020 they have been absolute garbage. Very frequent service outages, the "AI" setting the air conditioner to ridiculously high temperatures (like 26 Celsius / 79 Fahrenheit) when you tell it you are feeling hot, and completely useless customer support that can't even get your name right, much less resolve even one of your problems. Avoid like the plague.
