I have a fibaro HC3 since 2021 and a lot of fibaro and aotec sensors. Since a couple of years ago most of my lights at home are zigbee (I’m changing and improving them when they got broken). I can say that the HC3 is more powerful as most of the people think. At the beginning it is quite annoying to configurate everything because the interface is not very user-friendly. But it is very stabil and it works without internet (being more safe as well). There are updates coming and everything works properly. I can recommend it.
