IAS Zone: Zone Status Change Notification the Zone Status value sometime is 0x0011 and can be 0x0010 or 0x0001.Why?

That's status byte of IAS zone which you can refer to Zigbee Cluster Specification for details.

I knew the details.When I Pressed the key in End Device the status sometimes can changed 0x0001 to 0x0010 or 0x0011.Just press one key,why change to diffrent values?

Do you implement this end device or it's from 3rd party? If it is from 3rd party, you should check what this button would trigger.

What's meaning?Now I don't know how to implement.If I implemented this status change.How can I do to implement that Press one key can change to other status?

Can you show me your code to send IAS zone status?

Sorry, It isn't implement in my hand.I had implemented the other one.But not change.So I doubted is ZCL or other layer implement this?

I don't get it. Can you elaborate?

In my mind When I press my alarm key.there is one bit change to alarm(0x0001).In fact when I press alarm key,it works report 0x0011 or 0x0001 and 0x0010.This End device use other one project,so I don't know how implement this.

If the device is not implemented by you, I suggest you to ask detail from whom implemented it.
