The assumption that all IO roller shutters support the
setClosureAndLinearSpeed action was incorrect, only the RS100 IO does.
In order to maximize compatibility, use setClosure instead.
For the moment this means RS100 IO motors don't move in silent mode
anymore until we find a solution to differentiate them from others.
The single unique identifier of Somfy Gateways is the Gateway PIN that
the device announces via zeroconf (txt + hostname). There's no point in
setting two params to the same value.
Note that due to a previous mistake this fixes also getting the IP
via zeroconf, because the old code was comparing against an incorrect
identifier.
Add support for controlling Somfy smart home devices through their
Tahoma box (and the Somfy API).
The plugin currently contains support for roller shutters as well as
for venetian blinds.
