No. Problem Cause Remedy
1 The Sunny
WebBox does not
display any
Bluetooth devices.
An incorrect NetID is set. • Set the NetID of the PV plant
(see Section 6.2 "Configuring
Bluetooth Settings for the Sunny
WebBox" (page 24)) and repeat
the commissioning).
The connection to the
Bluetooth plant is too weak.
• Shorten the distance to the devices
or use an SMA Bluetooth Repeater
in order to extend the radio range.
Repeat the commissioning
(see page 23).
There are already four
masters connected to the
Bluetooth plant.
• Remove a master and repeat the
commissioning (see page 23).
There are already two
participants connected to the
device through which you
want to set up a connection
to the Bluetooth plant. • Change the position of the
Sunny WebBox in order to set up a
connection via another device in the
plant or remove one master from the
plant. Further information on
