Incomplete / outdated / faulty data on the user interface
Problem Cause and corrective measures
Data on the following pages is
not up to date:
• Current Status And
Forecast
• Energy balance on the
Current tab
• Load balance and control
on the Current tab
Settings in the router might prevent SunnyPortal from requesting current data
from the SunnyHomeManager.
Corrective measures:
• Ensure that the following requirements are fulfilled
– All UDP ports > 1024 on the router or modem must be open for
outgoing connections. If there is a firewall installed on the router or
modem, you might have to adjust the firewall rules.
– It must be possible for the outgoing router or modem connections to
reach all Internet destinations (target IP, target port). If there is a firewall
installed on the router or modem, you might have to adjust the firewall
rules.
– On the router or modem with NAT (Network Address Translation) there
must not be any port forwarding. Potential communication problems
can thus be prevented.
– There must be no packet filtering or manipulation for SIP packets
installed on the router or modem.
The page Energy Balance is not
displayed.
The Energy balance page is only displayed if the integrated measuring device
or a separate SMAEnergyMeter supplies measurement data from the grid-con-
nection point.
Corrective measures:
• Ensure that a measuring device is installed at the grid-connection point.
Assign the measuring device (integrated or separate SMAEnergyMeter) to
the point of interconnection in the SunnyHomeManager properties (see
Section11.3.12, page61).
On the pages Energy balance
and Load balance and con-
trol, the Current tab is not dis-
played.
The tab is only displayed if the data request interval is set to Automatic.
Corrective measures:
• Set the data request interval to Automatic (see Section11.3.9, page59).
SunnyPortal is not showing any
weather forecast in the diagram
Forecast and recommended
action.
It can take up to 24 hours after the SunnyHomeManager has been initially reg-
istered in SunnyPortal until the weather forecast is displayed.
Corrective measures:
• After 24 hours, check again to see whether the weather forecast is
displayed.
• If after 24hours there is still no weather forecast displayed, contact the
Service team (see Section23, page145).
The animated graphic on the
page Current status and Fore-
cast is not displaying any current
data.
The reception of current data from the SunnyHomeManager is only possible if
the data request interval is set to Automatic.
Corrective measures:
• Set the data request interval to Automatic (see Section11.3.9, page59).
