Re: How to set timers for z-wave devices

[nobody@xxxxxxxxxxxx (Dave Houston)]

As a general rule, scene data is stored within the switch or module so, yes,
they only work with devices that have scene support built in. It is a method
for having multiple devices (with multiple network addresses) go to some
predefined state simultaneously. The number of scenes that a switch or
module can participate in varies from with the type of technology (X10,
Insteon, UPB, Z-Wave) and manufacturer. For example, the X10 LM14A lamp
module can belong to 4 scenes. When it sees a command for Scene A it goes to
the level previously defined for it and Scene A. Other devices that
participate in Scene A will respond by going to their predefined Scene A
levels (which may differ for each participant). Each device can have
different levels for the different scenes it participates in. Most of the
technologies allow for many more scenes than does X10.

Scenes are popular with home theater arrangements where it's desirable to
set several devices at once.

Timers and macros are different. They are almost always stored in a master
controller/interface (for timers an RTC is needed). They cannot be stored in
the switches and modules because the latter have no RTC and, in most cases,
have no way to communicate with other receiving devices.
