I'm on the current build, I tested this new action and can see from the logs that it is sending the flash at 750ms to my caseta dimmer, but the dimmer doesn't do anything. Is there something else I should be doing to get this to work?
Sorry to OP for hijacking but I think this is probably the same question.
Just to make sure I understand this capability though, should I be able to "flash" any switch? Or doe the hardware have to support that capability? i.e its not a "virual flash"? If so, this may be why I can't use it
Yes, the driver and the device have to support it. Caséta hardware does not support it, but the driver does (because RA2 hardware does support it). Most Z-Wave and Zigbee devices support it.
