If you're an electrician, here's how to connect to a panel.
Firstly, ensure you're standing within a metre or so of the panel you are trying to connect to. Open and log into the Basis Trade app.
On the home screen, you will see a section called "Available Panels". The app will automatically start scanning for nearby panels. To connect to the correct one, simply press the black activation button, found at the top right on the panel itself.
The correct panel should come up in your app, however, you can verify this by checking that the serial number matches the serial number on the panel. Once you have done so, press "Connect" in the app, and press the activation button on the panel again.
This should now come up to show the panel and circuits, and you'll see a successful "Panel connected" message.
