I like to use smart home without cloud conncetions. I used version 2 for some months some years ago with the bridge and from time to time it stopped working as the connection was not really stable. Now I tried version 4 “pro”. still some bugs after years of development:
- wifi: the app offers wpa3 - but this does not seem to work in reality. connections are successful only with “mixed” mode
- mqtt: it is not possible to change the basic topic (nuki) or even the port - although the product is labeled “pro”
- mqtt: no encryption (tls certificates) is possible
- mqtt: the states for /state and /lockAction are labeled different?!?
at least the connection is stable over several days…
