Compatibility with the Sunny Home Manager
To ensure compatibility with the Sunny Home Manager, the Gateway Stretch firmware must
be of version 2.7.7 or higher. If Gateway Stretch has an older firmware version, an update
request can be carried out in the following way:
• Send the Plugwise Stretch ID (as printed on the Stretch type label) to Firmwareupdate-
Plugwise@sma.de with the subject line: Update Clearance Plugwise.
• Plugwise will clear the Stretch update for the firmware version 2.7.7 or higher. Normally,
the update is then performed automatically.
• A manual update can be triggered via the HTML interface of the Stretch (call up via
Plugwise app).
• The current Stretch firmware version can be called via the HTML interface of the Stretch
(call up via Plugwise app).
