False trigger?

[hannez82]

Hi,

I'm having a magnet sensor connected to my razberry. Over night I've have som false triggers that I see in the log. However, I don't see these events in the razberry gui so for some reason the gui filters these but my code that binds to the event gets triggered.

Is there some feature in the device perhaps that send an "I'm alive" event with the current status?

The log below is from the false trigger and it does not show up in the gui.

Whether there's such a feature, it depends on your device.

But the packet from the log looks like there is. The device sends battery level, alarm status, luminosity and temperature as one packet. It is hardly a coincidence.

Gui probably checks the "phantom update" flag on change type, and your code should too.

I see,

I found some code :

Code: Select all

zway.devices[4].instances[0].SwitchBinary.data.level.bind(function(type)
{
   if (type !==1){
     return;
   }

Is this what you mean? I'm having trouble understand what the type-variable is. I've tried the code but sometime my magnet sensor sends 65 when it's a correct event. Very confusing.

Yes, it is. You may peek at type constants in ZWave module:

Code: Select all

this.ZWAY_DATA_CHANGE_TYPE = {
	"Updated": 0x01,       // Value updated or child created
	"Invalidated": 0x02,   // Value invalidated
	"Deleted": 0x03,       // Data holder deleted - callback is called last time before being deleted
	"ChildCreated": 0x04,  // New direct child node created

	// ORed flags
	"PhantomUpdate": 0x40, // Data holder updated with same value (only updateTime changed)
	"ChildEvent": 0x80     // Event from child node
};

Ok thnx. It seems though that my pir-sensor from dlink always sends 65(DEC) as type and never 1. However it solved my problems regaring the magnet sensors.
