Firmware and device update, restart
Problem Cause and corrective measures
The automatic firmware update is
not working and there is a corre-
sponding error message.
The SunnyHomeManager may not be able to establish a connection to the
SMA Update Portal because there is a proxy server in your network.
Corrective measures:
• Configure the settings of your network in such a way that the SMA Update
Portal https://Update.SunnyPortal.de can be reached.
New firmware is not updated. The firmware update is always a 2-step process. First, it is downloaded and in-
stalled. At this point, the message "Update successful..." already appears.
The update is only active after a reboot, which the Sunny Home Manager per-
forms the night after the update.
Corrective measures:
• Check the update again later.
• If necessary, perform a manual device reboot (as per the device manual).
Device updates are not being
loaded.
Some devices can only get their update directly since the update file is too large.
Corrective measures:
• Check the status or event messages of the affected device.
If necessary, perform a manual device update (as per the device manual).
Restarting the Sunny Home Man-
ager does not work.
It is possible that the device cannot be accessed.
Corrective measures:
• Reconnect the device and perform the restart again (see Section11.8,
page68).
• In an emergency, you can also trigger the restart directly on the
SunnyHomeManager: Press and hold the reset button on the device with a
pointed object until the LEDs stop flashing red (at least 6 seconds).
