Panel Offline

eddymouse

Hi i have a level that commands a light dimmer.
When the 8400 wiFi panel go offline ( I hate WiFi!!! ) the level raise up a level 0 event so the dimmer go off.
How can I know if the panel is online or offline?
Thank's a lot!!!

Panels generate an online and offline event. Just make a DATA_EVENT for the panel with those handlers.

However, to avoid the level being sent to zero, you will probably be better served by combining your panel with a virtual, and using the virtual instead. Virtuals never go off line unless the master shuts down.

Other way to prevent this:

DEFINE_DEVICE
dvPANEL 		= 128:1:0


DEFINE_VARIABLE
INTEGER nBARGRAPHVALUE		// the active bargraph value


DEFINE_START
// we will NOT use a CREATE_LEVEL to Bargraph 1,
// because if the panel goes OFFLINE, the bragraph value goes to 0


DEFINE_EVENT
LEVEL_EVENT[dvPANEL,1] // Bargraph 1
{
	IF(DEVICE_ID(dvPANEL)) // only if Panel Device is online
	{
		nBARGRAPHVALUE = LEVEL.VALUE // take Bargraph value
		// send nBARGRAPHVALUE to any other device 
	}
}

DATA_EVENT[dvPANEL]
{
	ONLINE:
	{
		SEND_LEVEL dvPANEL,1,nBARGRAPHVALUE // resend latest value to the bargraph
	}
}


DEFINE_PROGRAM

DATA_EVENT ONLINE/OFFLINE has a higher priority as a LEVEL_EVENT[]. Because of this, The DEVICE_ID(dvPANEL) fails and the LEVEL.VALUE, which falled to 0, is not executed.
