Cause and corrective measures
It is possible that the Sunny Home Manager is not properly
connected to the router.
Corrective measures:
• Ensure that the Sunny Home Manager is correctly
connected to the router (see Section 7.3).
DHCP is possibly not activated on your router or there is a proxy
server in your network. For this reason, Sunny Home Manager
cannot establish a connection to the Sunny Portal.
Corrective measures:
• Establish the connection to the Sunny Portal using the
Sunny Home Manager Assistant (see Section 9.4 "Using
the Sunny Home Manager Assistant", page 56).
Sunny Home Manager has already been assigned to a plant with
your e-mail address in Sunny Portal.
Corrective measures:
• Delete the Sunny Home Manager from the plant (see user
manual of the Sunny Portal for Sunny Home Manager).
or
• Re-register the Sunny Home Manager using the Plant Setup
Assistant (see Section 9.7 "Reassigning the Sunny Home
Manager after Resetting the Sunny Home Manager Plant",
page 58).
Sunny Home Manager is assigned to a different plant in
Sunny Portal, e.g. if you bought the Sunny Home Manager
second-hand.
Corrective measures:
• If possible, contact previous owners and ask them to delete
the Sunny Home Manager plant in the Sunny Portal.
or
• Contact the SMA Service Line.
