Same for me!
I’m running 2 Smartlocks and 2 Bridges for 3 or 4 years and I’m satisfied with it.
I all have integrated into my FHEM-Solution but without permission for internet-connection to the bridges.
I also wish full access via API (insert/delete/modify user rights for keypad etc.) but WHITOUT internet-connection.
Thank you!
