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)
