Problem Cause and corrective measures
After you have entered the sys-
tem password and added de-
vices, some devices are shown
with a warning symbol in the sys-
tem setup assistant.
There is a different installer password configured in the devices with warning
symbols.
Corrective measures:
1. Select [Skip forward] in the system setup assistant and finish registration
without selecting the devices.
2. Set a uniform installer password for all devices via the inverter user interface.
3. If you do not know the password set on each device, apply for a Personal
Unlocking Key (PUK) for each device from the Service (see Section23,
page145).
4. Enable each device with the corresponding PUK. Then set a uniform installer
password in all devices.
5. Log in to SunnyPortal and add the devices to the SunnyHomeManager
system as new devices using the configuration wizard.
While the system setup assistant
is performing the device search,
the status LED of the
SunnyHomeManager first
flashes red for 1 to 2 minutes.
Subsequently, the status LED
glows green again.
Device detection takes a few minutes longer.
Corrective measures:
• No measures required.
18.3 Problems with Integration of Devices
Problem Causes and remedies
The SunnyHomeManager does
not detect any devices.
The devices must be connected to the local router via Ethernet/Wi-Fi and also be
able to communicate with the SunnyHomeManager:
Corrective measures:
• All Ethernet/Wi-Fi devices in your PV system must be in operation.
• The Ethernet/Wi-Fi devices must be connected to the router/network switch
correctly.
• The network cable connecting the Ethernet devices with the router/network
switch must be suitable for 100MBit/s.
• The Ethernet devices must be in the same local network as
SunnyHomeManager.
• DHCP must be activated on the router.
• The router must have an Internet connection.
• For Ethernet devices with integrated Bluetooth interface, the NetID of 0 must
be set. In this way, Bluetooth is deactivated.
• The LAN ports on the router / network switch may not be switched off in the
event of apparent inactivity (see router / network switch manual).
• The network switch may not use IGMP snooping (see network switch
manual).
