That is really disappointing to hear. The summer update actually stated that it would not be supported in 2019 which I did not interpret as never, but rather just not in 2019.
Perhaps, as an alternative, you could look into integration with the SmartThings cloud? This was my intended use case so integration here would be fantastic.
For what it’s worth, the product, and continued support is fantastic and so, whilst I find this decision very disappointing, were I to buy a lock again today, it would still be a Nuki 2.0 on my door.
Keep up the good work.
