    'details': {
        'path': '/org/bluez/hci0/dev_E7_37_97_XX_XX_XX',
        'props': {
            'Address': 'E7:37:97:XX:XX:XX',
            'AddressType': 'random',
            'Name': 'SmartSolar HQ2248AM79D',

            'RSSI': -89,
            'Connected': False,
            'UUIDs': [],
            'Adapter': '/org/bluez/hci0',
            'ManufacturerData': {737: bytearray(b'...')},

Device Key

You need the Device MAC address and the key.

The easiest way to get the device key: Install the official Victron Smartphone and and copy&paste the key:

• Click on your SmartSolar device
• Go to detail page about the SmartSolar Bluetooth Interface
• Click on SHOW at Instant readout via Bluetooth / Encryption data
• Copy the Connectionkey by click on the key

(I send the key via Signal as "my note" and use the Desktop Signal app to receive the key on my Computer)
