SMA sunny home manager - States of the BLUETOOTH LED

10.1.3 States of the BLUETOOTH LED
LED status Cause and corrective measure
Flashing blue The BLUETOOTH connection to the devices of the PV system is criti-
cal.
Corrective measures:
• If possible, select a different mounting location and check the
connection.
• If no other mounting location is possible, use an
SMABLUETOOTHRepeater or an SMAradio-controlled
socket. This will extend the wireless range of your
BLUETOOTH network.
Off There is no BLUETOOTH connection to the devices of the PV system.
Corrective measures:
• Commission the SMA BLUETOOTH devices.
• For inverters with BLUETOOTHPiggy‑Back: wait until the
inverters switch on.
It is possible that the NetID configured on the SunnyHomeMan-
ager is not identical with that of the PV system devices.
Corrective measures:
• Ensure that the same NetID is configured on the
SunnyHomeManager and the devices of the PV system (see
Section5.2.2, page35).
There may already be more than one additional master in your
BLUETOOTH network (e.g. SunnyBeam and computer with
SunnyExplorer). As a result, the SunnyHomeManager cannot es-
tablish a connection to the BLUETOOTH devices.
Corrective measures:
• Together with the SunnyHomeManager, use a maximum of
one additional master in the BLUETOOTH network.
