MAC address dabase
The MAC address database has been created using the dowloaded JSON data from https://macaddress.io.
Build database
Before you can start the build-database.py script, please make sure you downloaded the the online database in JSON format.
Once the macaddress.io-db.json file has been downloaded and placed into this folder, the python tool can be started in order to generate a read performance optimized and minimal database for searching mac address OUIs (Organizationally Unique Identifiers).
$ python3 build-database.py
The final database will be named mac-addresses.db.
In nymea the MacAddressDatabase will search for this database file in /usr/share/nymea/mac-addresses.db and provides an asynch mechanism to provide the manufacturer name for a given mac address.
