Cause and corrective measure
No energy meters or not all energy meters are connected
to the Sunny Home Manager or they are not configured.
Corrective measures:
• Connect the energy meters to the
Sunny Home Manager and configure them (see the
installation manual of the Sunny Home Manager).
Sunny Portal cannot receive any data from the
Sunny Home Manager.
Corrective measures:
• Make sure that the connection between the
Sunny Home Manager and the Sunny Portal is
established (see the installation manual of the
Sunny Home Manager).
Settings in the router 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 on the router or
modem.
Sunny Portal could not transfer the parameters to the
Sunny Home Manager.
Corrective measures:
• Make sure that the connection between the
Sunny Home Manager and the Sunny Portal is
established (see the installation manual of the
Sunny Home Manager).
