130	130	{{{* Zūm Setup App works as long as the NETBRIDGE is physically near the iOS/Android device running the Zūm Setup App.
131	131	** Fade time is automatically applied if scene is set longer than 1 second. Must be triggered from SHOWRUNNER™, cannot be triggered from Zūm keypad with current firmware (as of April 2020).
132	132	*** Zūm wireless does not support direct coupling of fade times and the behavior is different internally within the dimmer versus other Crestron products. Raise/Lower level accuracy is not guaranteed. For best performance when settings scenes, set the slider manually which will send exact levels to the dimmer.
133		-**** Zūm wireless scenes cannot presently be read. Scenes should be created and saved from SHOWRUNNER™ directly. Saved scenes are stored directly on the Zūm wireless dimmer.
	133	+**** Zūm wireless scenes cannot presently be read on command. Scenes should be created and saved from SHOWRUNNER™ directly. Saved scenes are stored directly on the Zūm wireless dimmer and in ShowRunner. ShowRunner will query the NETBRIDGE after scene recall and attempt to build scene information but operations are done one at a time.

	136	+==== Caveats ====

	138	+* Zum Wireless has an internal rate limit that will shutdown communication if a number of commands are received in a short period of time.  This can be seen when repeatedly pressing buttons on a keypad as well as repeatedly triggering actions from ShowRunner.
	139	+* Raise/Lower operations from ShowRunner cannot track directly with the load response, see ~*~** above.  ShowRunner will poll the NETBRIDGE for current levels ~~3 seconds after the raise/lower is stopped to obtain current load levels.
	140	+* Lower operations can turn the load off.  The load will not come on with a raise.  This is a firmware behavior in the Zum hardware.
	141	+* Wireless control presents some additional latency possibilities.  Commands required to provide full functionality (load control/raise/lower) with Zum wireless are more intensive than traditional Crestron hardware and may impact performance under heavy load.  Local operation of the Zum wireless room is not impacted.
