I have been using a Nuki lock in London-based property, integrated with Klevio for 2 years now (image enclosed). I have a door fitted with a deadbolt operated by Nuki, and an electric nigh-latch (deadlock) operated by Klevio. Klevio issued me with a digital key which operates both, the deadbolt (via Nuki) and the electric night-latch (via Klevio) in tandem, in that order and one after the other. So, if the deadbolt is locked and one clicks on this digital key to unlock the door, Klevio tells Nuki to unlock the deadbolt and about 2 seconds after it holds the night latch back for about 4 seconds so one can open the door. If the deadbolt is already unlocked, it only holds back the latch. Conversely, the same digital tandem key is capable of locking the deadbolt in which case, of course, the night latch is left as it is (with no instruction being sent to it).
The above-described locking set up worked well for a few months back in early 2021, however not for the last year and a half. We get tons of ‘time-outs’ (with in-app notifications) in which Klevio never manages to unlock the Nuki deadbolt, having to then open all locks with the physical key; the whole experience is a real pain and straightforwardly the antithesis to what one would call ‘smart’. So most of the time we just leave the Nuki deadbolt unlock through the day, operating only the Klevio night-latch with another digital key which actually works faultlessly.
Klevio engineers have checked and cannot see any obvious issue in their servers. However they suggested there may be a bluetooth interference where Klevio may be trying to communicate with the Nuki unit at the same time Nuki is trying to do it. Obviously if there is an ITTT protocol in place, this should work well and one should not have such a poor and frustrating experience.
With all that said, would an engineer at Nuki be available and able to liaise with me and hopefully with a Klevio engineer (they would like to visit the property and do a full assessment of the problem) to get to the bottom of this issue? As a result, it may lead us to stay with the current brands without ditching the whole ‘solution’ once and for all, and also to unforeseen product improvements for both companies, Nuki and Klevio.
Many thanks, Jav.
