 `account` is a bridge thing type that will allow automatic discovery and configuration of the available K1 connectors on the specified ELRO Connects account.
 This bridge is optional.

 Notice that K1 connectors in another network than the LAN will also get discovered, but will not go online when accepted from the inbox without adjusting the `connector` configuration (set the IP address).
 
 The K1 connector `connector` will be auto-discovered when an ELRO Connects `account` bridge has been created and initialized.

+It can also be configured manually without first setting up an `account` bridge and linking it to that `account` bridge.
 Once the bridge thing representing the K1 connector is correctly set up and online, discovery will allow discovering all devices connected to the K1 connector (as set up in the Elro Connects app).
 
 If devices are outside reliable RF range, devices known to the K1 hub will be discovered but may stay offline when added as a thing.
