Hi, my local makerspace is looking for a door lock.
It must preferably have RFID/NFC ( or magnetic stripe card), have Zwave or similar. Must be CE marked, or approved by European insurance companies.
So,- any tips ?
I recommend looking at commercial solutions instead of those designed for smart residences.
this is not a general smart home forum, but one for the openHAB system used in personal homes.
This https://en.wikipedia.org/wiki/MIFARE is being used in many hotels and e.g. for ticketing in public transportation. To make it work for up to hundred users is a matter of the database in the background.
