After countless attempts to couple my Huawei Watch2 with the NUKI, I eventually made it. I think the 4 sheet metal contacts for keystroke recognition on the NUKI are just total crap and absolutely cheap.
If I am sitting with my watch in front of the lock and I have my smartphone with me, I can open and close the lock with the Smartwatch.
But if I only sit with the watch in front of the lock, I get the message that no Smartlock is available. Only when I bring the mobile phone within range again, the watch will have contact to the lock again.
Obviously the connection is established as follows NUKI -> Smartphone -> Smartwatch.
That’s pretty pointless, if I leave the house without my mobile phone but with the watch, I can’t get in because even if I stand directly in front of the door, there is no connection to the watch because the mobile phone inside is out of range of the NUKI.
Android app version is 2.6.5
