Cool idea, but the lock is really quite expensive - 150 $ plus shipping.
Spontaneously I would say that you can replicate this inexpensively...
I would build a small box, material does not matter, probably just wood. Simple box, with a lid. A locking device is attached to the lid from the inside, for example an electromagnet with a bolt.
On it would now have a supply, 12 V transformer, a relay and eg an Arduino with ESP32 (wifi).
How it is then opened or locked is then still open, whether there is a keypad, or the Arduino has a small web page, or something else - many possibilities.
Over thumb calculated, 1-2 hours work for the box and 20-30 $ for the technology.
Since I like the idea, I will build that times and post here in the forum :) Thanks for the idea
but it seems an interesting way of locking things (like chastity key or something :))
